- 42" in-car harness layout
- Setup for GM E38 ECM's and T42 TCM's (if 4L60 or 4L80E)
- Corvette Accessory drive alternator and A/C compressor locations
(if using a self exciting accessory drive, you can ignore these two connections)

-LS3 MAF sensor
-Corvette C6 Front O2 Sensor provisions
-C6 Vette/GMPP/5th Gen Camaro Accelerator pedal

Computer(s), accelerator pedal, O2's, and/or LS3 MAF sensor are available with the kits if needed. We can also reprogram YOUR computer.

All harnesses were tested on a live engine/transmission here with the Tech 2 scan tool to verify proper functionality before going on the shelf!

Need a custom length harness or a custom harness to fit your aftermarket intake manifold or accessories, inquire today.

Feel free to email or call with any questions!

ARE YOU AWARE THAT WE PROVIDE CUSTOMIZED LAYOUTS AND HARNESS LENGTHS TO MEET YOUR SPECIFIC NEEDS? Many of our truck customers opt for under-the-seat installations, which require custom-made harnesses. This approach is particularly useful when working with aftermarket A/C systems or larger Gen V E92/E90 computers, as it allows for efficient mounting under-the-seat or under-the-hood.
