I have a 2007 ls2 58x reluctor wheel motor and I'm trying to figure out what all options I have for the wiring harness and PCM. I will be using drive by wire with a manual transmission and I currently have a '05 GTO harness with the foot pedal that I was used with the E40 PCM. I now know that this harness will not work with my motor and I will need to either use a E67 or E38 PCM. Question is, which would be a better choice? Also, does anyone have or know where I could find p/n's for a wiring harness from 06 and up C6/TBSS/SSR, or something similair? Or maybe a 06+ Aussie car with a gen IV motor? I've had no luck so far searching around on the net...
