1981 K5 Wireing issues

[FFF_05]

I was wondering if any of you would know where the wireing harness to power the cab/dash is, and also where is it supposed to be plugged into? I have been tracing wires all day and am not getting any power to the cab/dash components. I do however have headlights/brake/and turn sigs, and also windshield wipers. However, there is no power to heater/AC, or radio or guages, and no interior lighting power either. If anyone can help that would be great!

Are you getting power to the fuses for all of the systems that are not working? If not, my guess would be either a bad connection at the bulkhead connector, or a burnt out bus bar on the fuse panel.

Try checking the connector at the firewall, and see if it is loose. Test all the fuses and make sure they are getting power, I would bet that no power is coming into the fuse panel for those circuits.

You have a junction on the firewall above the distributor, and a couple fusible links that attach to the starter.
