I put power to the PCM tonight for the first time, so i could see if my Dakota Digital would communicate through the OBDII port and it wouldnt.... Even tried using my scan tool i keep in my car to monitor MPG ect and still nothing.
let me start by saying im completely self taught at wiring, very basic.
But tonight i had to get out of my comfort zone lol. So i found the pin out diagram on google for the PCM and found that pin 58 on the blue connector is the serial data for OBDII, so i got my Multi-meter and did a resistance test to the plug and got nothing.
next I removed every bit of the Loom to the PCM and traced the wire back to the number 50 pin out on the red PCM connector which turns out to be the VSS signal.... Turns out the VSS signal wire was wired to the 58 pin out on the blue connector with them being completely swapped.....
We are gonna try to start the truck tomorrow and hope the guy in OKC who did our standalone loom didn't screw up anything else
Wish us luck guys! i was able to get fuel pressure tonight and got the coolant added, just gotta turn her over a bit to build up some oil pressure and to get some fluid thru the trans.
