I have a 1994 K3500 that had a 6.5 in it and now it has a Cummins. I was wiring my truck up the other day, this is my first project by the way, and I got the Cummins to crank with the key. I have the fuel shutoff wired how it's supposed to be also. But when I did this swap I took out all of the wiring. I took the headlight harness out, engine harness and computer (sold that with the 6.5L), and the one behind the dash.
I figured out which wires were the 12v in, run, and start. I cut them after the fuse box but before the place where you plug in those wiring harnesses. I have the 12v in going to the battery, the start wire to the starter, and it will crank with that. I'm going to put it on a relay though. Then I have my fuel shutoff solenoid wired to a relay. I have the 12V going to 30, "pull" wire to 87, 86 ground, and 85 goes to the starter.
That's all I have wired up, I have my dash back in and everything plugged in besides the computer because I no longer have that. Now after I did this wiring I have no power to anything else in the truck. The lights don't come on when the doors open, no hvac, no radio, etc.. What did I do wrong here? Is there something else I need to hook up?
Sorry if it's stupid, I'm 16 and this is my first swap and the whole wiring part really really confuses me lol. Thanks guys!
