Iam in the process of restoring my 1976 chevy k-10, and I bought some doors from a 1985 chevy. They have power doors and windows. The original wire harness is in bad shape. Is their anywhere that I could get a wiring diagram so that I could rewire the doors, or better yet is their anyplace to get new door harnesses for both doors?

Doc here,

Your first , cheapest resource is the bone yard..for harness.

Next would be Ron Francis, Painless or EZ2Wire..

What year are the doors?

I show no schematic for an 86 truck..for door and windows..Could they be another year?

LMC truck will have those and many other parts you might need.
I only use them for reference.

Haynes manuals have many wiring diagrams listed in the back. At least the older versions did.

Doc here,

Thanks M&M, My truck schematics show no lock and window Diagrams at all..All I have is the diagrams for Corvette, which I would assume to be the same, but you never know, the color/Pins may Differ..although the procedure will be the same.

A lot of times the truck manuals had up dates only in them unless a new system was installed. I would not be surprized if the manual for the '78 had the wiring and they did not change colors that often so the colors code would be the same for years.

First question - is it a '76 cab? I don't think '85 doors will fit a '76 cab. I know the entire front cowl, fenders and hood are different, and I always thought they changed doors too.

I've been pulling wiring from other trucks to add power locks to my '75, and the window & lock wiring is fairly simple. I already have a third party power lock kit installed, but would like to switch to the GM system because the wiring and solenoids are much more heavy duty. In addition to the wiring in the doors you will need the lock relays that are mounted in the cab.

Take a look at Ebay and search for '85 Chevy and GMC wiring diagrams. For most years the wiring diagram is a separate book from the repair manual. I think I paid about $10 for the wiring diagram for my '75, and its original, not a cheap xerox copy.

Doc here,

Try the local County MAIN library Reference room for FACTORY leather bound manuals..Ask the reference room Guy for them, and if they don't have them ask if they can be outsourced from another system..

The down side is , they don't allow you to leave with the manuals (usually) so you have to copy them on site..Bring tons of copier change! other than that, their free..

The doors will physically fit from 73-87

the door panels changed in 78---also an inner skin change. So a change to 85 doors will require 78-80 door panels or 81-87 panels.

Also the vent window assy. changed in 81, not really a big deal as it will interchange with the older models. This change added a vent lock, and also changed the shape of the vent window (have to look close to see).

I see no reason why you cannot use a diagram (no electrical in my 79Service manual either) from any 2-dr GM.

Also "Electric Life" power windows will sell the necessary harness to plug into the GM 5-pin switches.

I believe Electric Life has a diagram online-----Dakoka Digital has a generic diagram online that may be helpful.
