Hey yall! Just picked up an 85 K5 and although the wiring is in good condition, there is a discconnect somewhere...literally.
Does anyone have a wiring diagram for it?
I hooked up a battery and the indicator, license, and tail lights turn on around the outside and on the inside the clock starts working and the radio and heater light up.
Tried jumping the starter out of the truck and that worked fine.
Thanks!

 

So what does not work? I assume it does not crank? Does the dash come alive at key on?

no crank, no click.

Dash doesnt light up. I'm gonna try replacing the lock cylinder and pulling the gauges out to test for power.

 

When I get a break today I’ll get out some wiring diagrams and help you through this. In the meantime I would start with power into and out of the ignition switch at the harness.

OK I have some wiring diagrams for your truck. Is this a manual or automatic?


George

 

It's automatic.
I pulled starter(jumped it and solenoid didnt even kick out) and the wired for it nearly disintegrated. Destroyed the lock cylinder, so I'm just gonna replace the whole ignition system.
Thanks George!

 

OK, let me know if you need anything else


George

 

One more thing, could you take a look at this wiring diagram I got offline and tell me if it looks correct?
Thanks

 

I cant read the details of this large diagram and i cant download it to zoom in. Try printing to pdf and attaching so i can download and zoom
