Ok i have the ls1 and t56 in my 85 mustang coupe. I have the wiring harness and pcm mounted and hooked up. I also put the gauge cluster out of the 2000 camaro and put it in my car and i thought i hooked it up correctly by using diagrams and schematics, but the only stuff that is working is the volt gauge, dash lights, blinkers and high beams. I need all the gauges to work..and i know it has somthing to do with the class 2 serial data wire. Can anyone that has maybe done a swap similar give me some pointers on how to get the serial data wires wired up properly? Theres gotta be something i missed.
