$339.95
09-14 Trucks*
- *Fits drive-by-wire applications with 5.3 L LH6, LY5, LMG, and LH8 engines and 4L80E automatic transmissions
PLEASE NOTE! Our harnesses are a standalone harness; meaning they will only control the engine and/or transmission, depending on your application. These will NOT communicate with body computers in a factory style application, nor are they intended to be a factory replacement part. The primary purpose and design is in an engine swap scenario, such as an LS swap into a hot rod or muscle car.
An LS engine swap is a no-brainer when it comes to adding some affordable horsepower to a project car, but any swap comes with its share of headaches, including wiring. That’s where TSP’s engine and transmission wiring harness comes in. It is designed for 5.3 L LH6, LY5, LMG, and LH8 engines from ’09 – ’14 drive-by-wire GM trucks with 4L80E automatic transmissions.
