Worked on the wiring for a few minutes today. Truck starts by the key now, and the shifter is working as it should. Only issue I'm having, other than the 4wd selector switch flashing, and not working properly, which was already an issue, is that when the brake pedal is pressed, the dash lights go out until the pedal is released, and the reverse lights are not working. The reverse lights are most likely only because the Park/Neutral switch bolts are only a few threads in at the moment and it is not adjusted due to nobody to help check on things while I adjust it.

Next step will be to check for power at Pin F of the PNP while adjusting it while in reverse. If no power then it could be a bad circuit running to the fuse, but I had to cut it short today to pick up my grandson. The only thing I found off in the fuse box/circuit pin out is that according to the pin out, is that it showed that the circuit for the reverse lights comes from the VCM C1 connector at the F3 pin, yet the wire showed continuity to the C2 connector at the B11 pin.

It could be that the circuits run together, but the power gets routed to the other circuit when reverse is engaged. If that's the case I will have to cut a couple wires and test them again. Likely pins C and F, although I really don't care about the reverse lights, but I would like the dash lights to work when I hit the brakes, and it'd be nice to be able to get it all 100% working.

Once I figure out the reverse lights, and the dash lights going out, I will have the circuit pin outs complete, and will post them for anyone who may need them in the future.

 

So no updates lately. I've been busy with other vehicles, and remodeling my bathroom, but I will still post the wiring here when done in case anyone needs it in the future.

The dash light problem was fixed, and I noticed that the headlights were not working, unless I jumped power to the fuse, but that should be an easy fix. I still have to clean up the wiring a bit more, make sure it's tied up away from any hot or moving parts, and reconnect the y pipe and drive shafts so I can drive it home and put in in my garage so I'll have time to finish it up.
