City, MI (August 16, 2019) – Howell EFI, the conversion experts since 1988, is well known
for the company’s large number of Jeep TBI kits for off road, in addition to
kits for the 304, 360 and 401. Howell now offers Ford TBI kits for any classic carbureted inline 6 or V8 Ford application. The
Ford TBI kits are ideal for increasing drivability, and improving fuel mileage
and cold starting in older street-driven classics and 4-wheel drive vehicles.
TBI kit provides everything needed to convert an I6, V6 or V8 engine from carburetor to
throttle body fuel injection. Howell EFI Owner Matt Howell says, “For ignition
systems other than points, and regardless of the configuration, we are able to
develop a TBI kit that will do what you want it to do. If you don’t see the part number you are
looking for, give us a call. This is a simple system that you do not have to
Howell TBI kit features a remanufactured GM throttle body appropriate for the
engine size for both engines with, or without ECM controlled ignition including
all sensors, components, wiring harness, ECM and fuel pump. Every kit includes
custom calibration PROM and an ECM that installs under the dash.
The fuel pump installs into the main fuel line, and bypass
fuel is returned to the tank. The harnesses are equipped with a diagnostic connector that works similar to a 1987-92

Four-wheel fun comes in a variety of methods and manners these days from the bombastic custom builds of Baja trucks and buggies, and jacked up Jeeps and pickup trucks from the ‘big three,’ to foreign import models cruising down the road built more for comfort and convenience over outdoor spectacle.
With everyone getting in the game of conversions, regardless of the intention for on or off road use,specific to the Pacific Northwestern region lies a specialized shop converting the classic 4 wheel Toyota Landcruiser, supporting the many years of classic models and nostalgic Japanese imports. Along with many various suppliers and vendors, Landcruisers North West (Portland, OR), chooses Howell for their EFI.
“They don’t just sell you the parts and ignore you after the sale. In over 10 years of working with Howell, they’ve been easy to work with and if there was a problem we’ve always gotten it sorted out. They help with troubleshooting and assist in finding any issues we may encounter.”
Matt Gustafson of Landcruiser NW
Landcruiser NW co owner, Matt Gustafson, has been raised on Landcruisers from his first days with a driver’s license, to his current ‘91 2-door soft-top 70-series, with an 89” wheelbase, sporting a V8 5-speed. “My first car was a Toyota Landcruiser,” says Gustafson. “When I was 16 yrs. old, I bought a 1970 Landcruiser and that was the start of the hobby. Five or six years later, my buddy and I started our Landcruiser shop.”
Gustafson started his company at 22 years of age during an internship straight out of college. With his first dabbling in corporate America, he quickly learned the soul-robbing trade of time for money, corporate agenda and yes-man games required to succeed in the suit-n-tie role, probably wasn’t for him. In seeking out his personal interests instead, the two-man team decided to start their own brand of Landcruiser shop.
Specific to the Gustafson brand is the opportunity to leave the city streets for the splendor of the Pacific Northwest outdoors. Plus with the lack of a harsh winter, nor any salt on the roads, Gustafson says, “Landcruisers survive here very well. We don’t have any corrosive chemicals all over our vehicles. And with our SUV/outdoor-based lifestyles, our heaviest load is a surfboard and maybe a bike, on our way to the beach or up in the mountains.”
The Landcruiser NW business has seen recent upticks in business with the Landcruiser now coming en vogue. As with many auto enthusiasts, when the daily driver becomes a toy to play with as well, often times the wrenches come out and the imagination starts to run wild with ideas of modifications and enhanced performance. “Many of our customers look at the prospect of restoring a cool old car and driving something that’s fun and exciting, over spending the same amount of money on a modern-day design that doesn’t have much soul to it,” says Matt.
With not only his personal passion for Landcruiser supporting his business, but also the reputation of a solid product from the manufacturer, Gustafson says it’s helpful to build our business on quality and reliable products. “When you start with a good foundation, and stick to the high standards and the same quality of your modifications, it’s easy to develop a good reputation in our work, and the cars will last for a long time. And regardless of crazy modifications or remaining with stock from the factory, we want our work to make the car as safe, if not safer than it was, and we have to deliver a reliable car that many times is even more reliable than when we started.”
“For example, we use Howell EFI because they offer a fuel injection conversion that works with the factory Landcruiser engine,” says Gustafson. “Howell uses basic throttle body and fuel injection components that have been proven over the last 30 years.” Gustafson claims that if he does some work and then sometime later the car ends up in someone else’s shop, “If they have to scratch their head to figure out what we have done in our shop, our modification is not all that good. With Howell however, if I make the mod and it goes somewhere else, the other shop is going to easily recognize the parts and the process.” As with many shops, the mechanic is often handed a project of wiring and harnesses that have seen multiple modification and molestation over the years. “One of the things huge for us,” says Matt, “is that Howell makes a stand alone wiring harness for old cars that I can install and easily rebuild the system, reliably and correctly.”
When Gustafson started his business in 2002, he says he was looking for a company that made a stand alone wiring harness so he could choose his own inputs like A/C, electric fans, or whatever their needs become. “There is a lot of generic stuff out there but there are very few that I can determine for myself this type of connector for the fuel injector, I want it to have two electric fans over one, I’d like the harness adapted to the passenger side instead of the driver side of the engine, or even super long so I can install from the trunk, or whatever the situation may be, with Howell, they make all of that stuff, and provide the full kit with everything I need, in one stop. Yes we work for improved efficiency, horsepower and enhanced performance, but we strive first for quality, safety and reliability in our builds. Many times we need the attributes of one harness included in the attributes of another harness. Howell helps us do that.”
Matt also enjoys the reliable customer service from Howell, with their dedication to ‘make it work.’ Matt says, “They don’t just sell you the parts and ignore you after the sale. In over 10 years of working with Howell, they’ve been easy to work with and if there was a problem we’ve always gotten it sorted out. They help with troubleshooting and assist in finding any issues we may encounter.”
Matt advises for any modifications to always keep in mind reliability, safety and the future service. And whether a fuel injection conversion from a carburetor, or swapping in a fuel injected engine, stick with the basics. “When someone gets too exotic with their mods, it makes it very tough to service five or 10 years down the line.”
After 20 years in business, Gustafson continues his excitement for his Landcruisers and auto projects to come. “Just last week I found a really cool ’65 FJ45 pickup out in the middle of nowhere, and I am super excited for the previously unavailable ‘70 series Landcruisers coming in from Japan too! We end up in a lot of treasure hunts. When someone knows of something cool out there, they usually give us a call. We are picking up a Landcruiser fire truck, coming in this week, that will be a really fun conversion.”
The Jeep Grand Wagoneer was an iconic sport utility vehicle dating back to even before SUV was ever coined as a hip genre of automobile. For many it was the original 4-wheel drive wagon allowing a sporty flair, not only for off-road adventure, but also toting around the family and perpetual drives to the grocery store. For Jeep/Chrysler, the Brook Stevens design was a gold mine, making its way from the woodsy trails to suburbia driveways across the map. With the signature woodgrain panel sides, the Woody was recognized coast to coast as the go-to family four-by.
For Chip Miller of Wagonmaster Jeep Wagoneers (Kerrville, TX), the Grand Wagoneer has been a lifelong family tradition reaching back to his childhood. His earliest memory of a Jeep was the 50’s-model Willis CJ3B, owned by his grandfather, on a ranch in Dillon, Montana. Miller says he has a picture of his dad holding him at about 2 years old, with the old-style army looking Jeep in the background, with the hood up.
With his baby pictures providing signs of future duties to come, the 70’s pre-woodgrain Wagoneer Limited entered the picture under his father’s ownership and the passion for Wagonmaster began without even knowing it. “I remember when my dad bought his first Wagoneer Limited in late 1978,” says Chip, “It was the first to have the full woodgrain.” The following year, Chip’s father, Leon, purchased his second Wagoneer as another workhorse for their ranch in Texas. “Versus the open air CJ, with no air conditioning and such,” says Chip, “the Wagoneer was also something that you could get out on the highway for a comfortable drive into town. In 1982, he bought another.”
In 1984, Jeep changed the name to Grand Wagoneer. The wrap around tail lights were replaced by an embedded upright tail light (similar to the Jeep Cherokee), and Jeep/Chrysler added headrests. Both updates were incorporated into the design until the discontinuation of the model in 1991. “We were a family of six kids, and the Grand Wagoneer remained as our ‘people transporters’ throughout the decades.”
“We come by all of this (Wagonmaster) business honestly,” says Miller. “When I joined my dad in 2010, I began to listen to our customers’ interests and motivations, it’s still the same thing with their Wagoneer too. That it’s the family heirloom, it’s the heritage, tradition and legacy of their memories; fishing trips, riding in the backseat with the neighbors, the dentist three-doors down having one in the driveway and the eagerness to have one too. And we’ve been lucky to speak to and hear the stories from the Chrysler designers that were in the trenches when assigned the tasks for the new truck to compete with Chevy and Ford.
With their stock well entrenched into the Grand Wagoneer lineage, Wagonmaster has restored over 2000 vehicles, and the shop may have 70 to 90 Wagoneers on hand at any given time. “We continually hear stories of trucks for sale out there and we try to be picky in our selections,” says Miller. “The low mile, barn finds go to the front of the pack, and begin immediate restorations, so we can bring it back to life and get into the hands of our customers. We update the car and our 26 years of business is always forward progression for parts and systems processes, and typically in prices as well. We are always moving forward, producing a steadily more and more enhanced Wagoneer. Plus in doing so, we are raising the value of all the others out there as well.”
For example, Wagonmaster perpetuated the carburetor fuel intake for the first 18 or 19 years of business. “As improvements surfaced, we then offered the option of carb or injection (circa 2014). After a year’s time phasing out of the carburetor, however it was clear that injection was the way to go,” says Chip. “Increased additives from the refineries made it tougher and tougher for the carburetor to remain tuned. Modern day fuel formulas were causing the repeated need for carb. rebuilds and we had to eliminate the issue. My dad wanted us delivering vehicles, easy for anyone to drive; without choking, pumping without it dying, blowing power valves, without the backfire and the continual issues of the carburetor. Our customers experience the same nuisance many times, as a helpful incentive for them to sell the car to us instead.”
Miller says, “We chose Howell Fuel Injection as our vendor because they had a much more simple, throttle body-type system that easily bolted on, providing us the ability to install and manage the settings on our own. Plus, we needed an injection system compliant within all 50 states including the California Air Resources Board. With the longevity of the company, and one of the original fuel injection systems on the market, Howell helps us deliver a product of our service, that meet’s my dad’s standard, for the ease of driving a Wagonmaster rebuild.”
Miller approximates that Wagonmaster has installed over 300 Howell injection systems in their vehicles, to date.
“When people ask of typical breakdowns with a Grand Wagoneer, I have three main issues I typically see; 1) Carburetors need rebuilt, 2) Rear main seal needs replaced, and 3) Tailgate window doesn’t function” says Chip. “We see dysfunctional tailgate windows, inoperable relay switches and we always recommend, without hesitation the conversion from carburetor to EFI.” With his advice, he says many will call back saying my car has never run better. “And I love hearing that!”
In his quest forward, Chip Miller and his Wagonmaster team continue to forge ahead in their service and their deliverables. “I’m always on the lookout for the next Wagoneer, and I’m surprised every day,” says Chip. “When I first started in this business, I always wondered from where will I find the next one, and stay in business? I’ve since learned I’ll run short of money before I run short on cars!”

A custom wiring harness and kit are the only way to go with Electronic Fuel Injection conversions.
Not all vehicle builds are the same. That’s why they call them customizers, right?
The fact is that when converting an originally carbureted engine over to fuel injection, there are man upgrades that are required to make it work properly. Electric radiator with thermostatic controls, fuel pump relocation to the gas tank and exhaust oxygen sensors required to make the fuel injection operational all require a custom wiring harness with the right fittings and the proper length wiring to connect it all together. No “cookie cutter” conversions kits could possibly do the job.
“We see a lot of online conversions kits that claim to be a one size fit all solution for folks converting their cars to electronic fuel injection,” said Matt Howell, President of Howell EFI. “But the fact is that these are very complex systems that need special attention to the layout of the wiring harness and the right matching components. We spend a considerable amount of time on the phone during the order process to make certain every piece of the kit is better than OE spec.”
Howell wiring looms utilize better than original equipment wire. The individual connectors used are exactly the same as those used by the original manufacture to ensure perfect attachment to the assigned component each one labeled with white tags to make for trouble-free installation. Best of all, when ordering a Howell EFI conversion kit, everything is included. Case in point for the classic Jeep carb to EFI change out, the kit features components like a new Throttle Body and computer module specifically programmed by Howell to the requests of the consumer. It is literally turn key!
“We have people who call in thinking this is a simple process because they have done some research online or actually bought a cut-rate conversion kit thinking that they had everything they need for the job,” said Troy Brown, Howell EFI Tech Director. “But it becomes painfully obvious that without attention to these details, the system will either not run at all or it will start but not deliver the performance they expect. We get too many customers who spend good money only to find out that the discount system was a total waste of time. We spend a lot of time to get it right and an equal amount of time researching new and updated systems either to enhance our existing systems or expand out coverage to include new models.

No vehicle on the road (or off road) benefits more from swapping from a classic carburetor to electronic fuel injection than a Jeep After all, eliminating those angle sensitive float bowls that can starve an engine for fuel and creating an engine system that can adjust to the altitude of the climb by richening and leaning out the fuel delivery is every Jeep lover’s dream.
Howell EFI offers eight different kits for most Jeeps built between 1982 and 1993 that originally came with carburetors. Best of all, for the street-driven Jeeps, the conversion kits include full emission compliance within strict Air Resources Board mandates. That means owners will never have a problem with the local regulators when checking emissions compliance.
“The Howell EFI conversion kit integrates the critical charcoal canister and the EGR systems and eliminates the need for the air pump and other engine cluttering components,” stated Troy Brown, Howell EFI Tech Director. “What we do recommend is that owners who install this kit go on our website and print out Air Resource Board Executive order D452 and keep this two-page document in their Jeep. This document shows that our system is emissions complaint and should handle any issues they encounter.”
The Howell EFI conversion kit includes everything you need to install the kit including the GM Throttle Body, reprogramed computer, high flow electric fuel pump, fuel filter, MAP sensor, all hardware, clips, mounts and most importantly, the custom factory-look wiring harness that uses better-than-factory components and wiring. Howell estimates that most of their Jeep conversion kits will take between 8 and 10 hours to install depending on your level of skill and the condition of your Jeep.
Key points to the installation include modification of the fuel system. Fuel injection systems require both a fuel delivery line and a return line, both running the length of the vehicle from the fuel tank to the engine. The recommendation is that this line be 5/16-inch diameter line, either braided steel or hard line. Rubber fuel line or steel line, if so desired, should be used but when using steel line, small sections of rubber hose are allowable around the new fuel filter and fuel pump to make them easy to service when needed. Many owners choose to mount these parts inside the transmission protection pan to avoid the buzzing noise notoriously emitted by electric pumps. Mounting the pump with some kind of rubber foam spacer where it touches the pan will keep the noise to a minimum.
The MAP (Mass Air Pressure) sensor supplied with the kit is a key component to proper operation. Howell EFI offers two types; one that can be simply installed off the TBI unit with a stiff piece of rubber hose or a second type that must be mounted in a downward facing angle with vacuum pointing towards the ground and the sensor mounted above the TBI unit itself on a bracket or the firewall. When reviewing your instructions, the MAP mount for your component will be noted.
Your Jeep’s computer is located within the interior behind the glove box. The dashboard on the passenger side must be loosened to allow for removal of the glove box. Once it is removed, the computer is easily located. Two nuts located on the engine side of the firewall must be removed to release the computer. Once it is free, gently remove the original equipment wiring harness junction from the computer.
The CTO (Coolant Temperature Override) switch is mounted on the engine block just below the intake manifold. It will be retained for any conversion and must be working properly. These switches are notorious for leakage, so if yours is showing its age it must be replaced. In addition, the original engine block mounted mechanical fuel pump will be removed and replaced by the block off plate supplied with the Howell EFI kit. The original pump rod stays in the block or the engine or oil pressure will not be correct. Make sure that the Howell plate is well sealed or oil leaks will occur.
For those looking for an overview of the system and owner experiences, YouTube-based instructional videos are readily available. “We have Jeep owners who go the full route and take out all of the original wiring loom and those that just tuck the unused original wiring away in the dashboard after heat shrinking the powered wires so they don’t ground out,” said Troy. “It is at the discretion of the builder as to how much or little they want to do – as with any vehicle modification. We honestly estimate the total install to not be longer than 10 hours from start to finish. The key is to study the schematic supplied with the kit and call our tech line if there are any questions.”
With many of their electronic fuel injection conversions, Howell EFI includes a drive-by-wire (DTW) pedal assembly that must be mounted in the new vehicle to control the throttle. DTW first appeared in Corvettes back in 1997 with the dawn of the C5 models delivering far improved throttle response than the previous cable-driven systems. By 2005-2007 almost GM vehicles switched to the DBW wire system, which delivered these benefits to all LS-powered vehicles in their line up. The beauty of this system for enthusiasts is that they can place the throttle pedal in any position they like as long as the wiring harness has enough length to reach the new positioning. In addition, they can be combined with traction control and ABS completing a state-of-the-art vehicle control system.
Without most recent installation, removal of the original throttle pedal was a terrific move since the years of wear on the original parts meant their future was limited. After unbolting the original mount, it was clear that the new DBW pedal system would not mount cleanly to the flooring and allow the pedal to move and operate properly.
After a quick call to the Howell Tech line, it was clear that a custom pedestal is required to properly mount the pedal. Researching the program further, a call to Steve Rupp, editor at Chevy High Performance Magazine netted his solution, which delivered not only proper pedal operation but excellent toe-heeling ergonomics. Bottom line, creating a plate to mount the DBW system is as unique as you want it to be. Here is an example of the solution used for Rupp’s Camaro – yours could be different.
Howell EFI announces availability of 2014+ EcoTec3 4.3L V6 LV3-C truck wiring harnesses, allowing for transplant into an unlimited number of applications from Street Rod, Pro-Touring, Off-Road, Sandrails, Street Machines and more. For ease of installation, relays are included, wires are clearly labeled and terminated, and one ground serves the entire system. Harnesses also include 6L80/6L90 transmission functionality making the installation of these engines and transmissions as easy as possible.
Each new harness also features its own fuse block and a GM diagnostic connector. This allows customers to have their vehicles easily diagnosed and serviced at any repair facility utilizing the common OBD II port. Installation requires just three points of power at the battery, ignition, and fuel pump making these harnesses truly plug-and-play. Harnesses are prepared to customer specifications, not a one size fits all approach, and each incorporates a rugged nylon or OEM style plastic covering and glued shrink tube. ECM/TCM reprogramming needed for the swap is also available. Each harness is proudly made in the USA with a Lifetime Guarantee.
According to GM, the 4.3L EcoTec3 V-6 has one purpose – providing budget-conscious customers a great standard engine. It’s large 4.3L displacement provides class-leading torque (305 lb-ft) and available towing (7,600 lbs.) for a standard V-6, while its aluminum cylinder heads and block saves weight. Its ability to operate on four cylinders under lighter loads helps improve fuel efficiency. Look to Howell EFI to make a transplant happen with ease.
