Mystery fuse box in 81 k10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

juiceboxhero · 06-21-2018, 02:01 AM

Hello, i am having some serious wiring issues with my new k10 i got. Mainly instrument panel and headlights. The owner was unsure what they had done other than a serious wiring headache. I know its an 81 frame, supposedly 85 cab and various other mismatched parts from other truck. I would like help to identify this fuse box because i am almost certain its not the original and i cant figure it out.
Any help would be awesome.

Well to help I would look under a 85 fuse box first. There is some wiring pic's on this forum do a search. I guessing if it's 85 cab and it have the fuse box in it to save work they used it. Write down all the options that are on the truck hooked up then see what fuses are in the fuse box. To see if they match each other. IE: a/c fuse in fuse holder but truck does not have a/c.
It had to see you fuse box clear to read it.

Thank you pontiac1976. I did more digging and ask some more questions. And it turns out they took it off an 85 to 87 c10 with all the accessories at the time. The original cab has no ac but the dash and other components are meant for more options. So the fuse box doesn't match the cab. Its a cluster.
