Here are some 1980 diagrams for you.. And

Since I found a few more of the diagrams I had, I created a permanent web album for them. They cover 1967 - 1987 Chevy Truck and Blazer. Not complete yet, but I will add to it as I find them. If anyone wants items added, just email them drew@eyehike.com

jimfulco · 02-18-2009, 03:50 AM

www.autozone.com has some diagrams. Click on Repair Info, then on Vehicle Repair Guides. Pick your vehicle, then click on Chassis Electrical, then look low on the right for Wiring Diagrams.

I have a GM wiring diagram book for Chevy 1973 light duty trucks. I need to scan them in so I can share with all. I will try and remember to bring it to work tomorrow so I can do that.

Dads79GMC · 02-18-2009, 11:31 PM

Here's a couple basice wiring diagrams for a 1980 C10, hopefully you can see the attachments. If you need something specific, I can probably narrow it down for you. Mike

Upload keeps failing, sorry.

60ratrod · 02-18-2009, 11:48 PM

well none of the attachments/scans showed up on my computer. hm....

I have one for a 1985 that I used to rewire mine. It is a pdf file but it won't let me upload it. If you want it or if someone can upload it for me shoot me a pm with your email.

i have a complete set of electricial prints for 82 model trucks ... i purchased for the restoration of my 82 stepside...if anyone needed a copy id be happy to copy and mail them a set....

snowbuzzard · 06-27-2010, 10:14 PM

Old thread, same request so thought I'd renew this one.

I need a wiring diagram specifically for an 87 chev 4x4 with dual tanks, if it even exists.

All kinds of one offs here, mostly TBI on the 73-87 body style.

I'm donoring a cab from a 2 wheel drive single tank to a 4 wheel drive dual tank system and need to know the wiring for the tank switch and where to tie in the 4wheel indicator light.

I would love to use the old wiring harness as an indicator, but the dingbat before me burnt it and then proceeded to cut it all out and throw it away.

Dummy me got the donor truck with the promise it had dual tanks, and I was too stupid to check until now..ugh. Live and learn. Any help would be appreciated guys.

This harness is for the Electronic Spark Control HEI distributor on a 305, or perhaps other engines too. The connector in your hand goes to the coil (it's B+ I think), and the 4-way Weatherpak connector in the background goes to a connector coming out of the distributor for the ignition module.

I *think* this is for the tip-in vacuum switch for the lockup converter on a Turbo 350C transmission.

This is a test connector that is normally disconnected. I can not recall exactly how it's used, but it has something to do with the lockup torque converter, probably to visually see when it engages via a test light or something.

Hopefully this helps!

Jdlawrence1 · 03-18-2013, 12:55 PM

Ok i see all the wiring diagrams but im not seeing the one im needing. Does anyone have the wiring diagram for the electric windows on a 1980 silverado? All im finding is the 82-on diagram. I need the one that shows the driver side double switch with 5 prongs and the passenger side switch with 3 prongs.

Thanks in advance.
