Howell EFI is pleased to introduce their new 2016 LT1 Camaro, 2014 – 2016 LT1 Corvette, and 2015 – 2016 LT4 Corvette harnesses, as well as its Ecotec3 truck versions for the 2014 – 2016 4.3L, 5.3L and 6.2L GM Gen V engines. 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.
Howell EFI provides more vehicle coverage for these engines families at better prices than any other harness maker in the industry. With the ability to put an LT1, LT4, or Ecotec3 engine into basically anything you want, these new engines are sure to become very popular swap options. Each harness is proudly made in the USA with a Lifetime Guarantee.
Look to Howell EFI to make it happen with ease.
