This harness is designed to be a complete stand-alone engine wiring harness with all brand new wiring and connectors to suit any model vehicle with an LS1 PCM and supports any mechanical automatic transmission, any manual gearbox and both factory 4L60E & 4L80E Transmission.
It is designed for a D.I.Y application, which also comes with its own instruction booklet to assist you in completing your conversion. Avoid broken wires and connectors with your second hand harness.
This harness is ONLY if you have an L76, L77, L98 or LS3 (6.0L-6.2) engine that is setup without DBW (electrical throttle) and it has been replaced with a mechanical throttle body. The only way to make your engine run this way is to use an LS1 PCM, which was the only computer to be able to control a mechanical throttle body. This wiring harness includes everything that is needed to make the LS1 computer run without needing to buy external wiring adapters or extensions. Everything is incorporated in the harness which makes for a neater finish and less complications.
The TRG-002 Lingenfelter Conversion module is needed for this conversion if you have not changed the reluctor wheel on the rear of the crankshaft. The factory 6.0L – 6.2L has a 58tooth reluctor wheel, where the 5.7L LS1 has a 24tooth reluctor wheel. The TRG-002 tricks the computer to think it now has a 24 tooth reluctor wheel, without having to change it from your engine.
Lingenfelter Module Wiring Upgrade (Plug & Play)
The TRG-002 is designed originally to be plugged into the crank sensor and the cam sensor, then mounting it wherever the harness ends in the engine bay, then needing to power and ground it. This wiring upgrade we offer we integrate it into the harness you are purchasing as a plug and play setup and fits neatly under the dashboard away from the engine bay heat and any water. You won’t have to do any wiring at all with this upgrade.
Our New Design Fusebox
Our new updated fuse box which is now included as standard, has been designed to accommodate everything that you require to complete your LS Conversion without the need for any upgrades. It is designed to control everything needed to make your engine run which takes all the hard work away from you.

Cloth Taped Harness Package
The stand-alone engine harness is finished in standard black harness tape to suit conversions that don't require a detailed show finish and prefer a standard finish. For conversions that require a show finish harness, the upgraded show package includes an overall harness modification to the lengths of each component of the engine bay, allowing you to run the harness much neater then factory to create a more hidden wiring look on your engine, and comes with a complete wrap of a stylish cloth tape of the complete engine harness which is also liquid resistant.
