I'll start with what I have/did. 96 12v manual truck put complete 00 v10 quad cab on it, dash and all. Using 98 pcm and engine harness hooked to the v10 fuse box and wiring. Swapped sensors to 98 12v so it all plugs in correctly. Obviously the v10 had no pin to power up the fuel solenoid relay...
New member here from CO. I was google searching trying to find a 98 12v harness and got led here. Hoping to find what I need to get my truck back on the road.
