The LS3 | LS7  Gen IV Wire Harness:

Welcome to the LS3 wire harness, built by Speed Scene Wiring, Made U.S.A. The LS3 engine wiring or as many call it, LS3 engine management system requires solid integration with the GM LAN, and all associated computers. The LS3 harness will support active fuel management, giving you the full access to every option that GM has engineered.

With every fly-by-wire LS3 harness we build, we supply the pedal harness. If you have the pedal, we will need it to test your application upon completion. If you are in buying a new accelerator pedal, always stick to the exact year, make and model the engine came out of.

Transmissions used with the LS3 wire harness are. 4L60E | 4L80E | 6L80E | T56 | 700R4 | Any STD Trans. Special programming and additional computers are required.

All GM engine fuel management computers need re programming and re mapping. We can handle any programming parameter changes you have made. SSW removes anti-theft and body programs, linking the LAN with the ECM. The LS3 engine wire harness is found in many different vehicles – ranging from the 2008 to 2011- LS3  vehicles listed below.
