LS Harness Connection
Integration Harness Assemblies

LS Harness Connection was built around the standalone-style wiring harness. This is a build that allows you to use that harness to control a specific powertrain in any vehicle of your choosing - whether you are swapping a boat, airplane, or car, the standalone harness will allow that engine and transmission to operate as a standalone unit - separate from the vehicles electrical systems. There are some wires that will need to be connected for operation, while others are optional and depend on how much you want to tie the systems together.

​

An integration harness does everything for you. While some companies have advertised their harnesses as "plug and play" they are actually standalone style and still require you to make the connections as noted above. The integration builds will repurpose some of your swap vehicles wiring and OEM power distribution center to allow the LS/Vortec/LT platform to function inside of your swap vehicle, while keeping all other functions that are a part of the OEM power distribution center and engine bay harness. This will create a truly plug-and-play system for your swap and ensure that you have all lights, horns, ABS, and other functions that were present on the vehicle in OEM configuration.

​

Currently only the 88-98 Chevrolet/GMC C/K truck and SUV are supported for integration, but there are plans to branch out to other chassis in the near future. If you have something that is not offered below, please contact us to see about having the first LS Harness Connection integration harness for your vehicle created!

If you already have your engine and transmission selected, please select the correct engine generation below based on the reluctor wheel and engine control module being used.
