Wiring Schematic - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mrnapolean1 · 05-30-2016, 05:53 PM

I have a 94 Chevy pickup C1500 that had been involved in a wreck with a cow.
The guy We got the truck from had gone to the junkyard and pulled a front clip from a possible 97 model truck.

I need a wiring schematic for the 94 wires going to the front coming out of the firewall block (see picture 1) and I need one of the round 6 pin pigtail (see picture 2)

I am trying to avoid from having to snake all the headlight wires thru the old broken core support and use the new undamaged ones on the new front clip.

Picture 1:

Picture 2:

There is another pigtail that I have already figured out. It has two green wires. 1 wire goes to the horns and the other goes to the A/C Condenser Pressure sensor. (wont be used because the 94 doesn't have this installed.)

I just need to know what wires go where before I cut anything.

The Schematics are no longer separate from the service manuals starting in 1994.

Links to PDFs many of the 88-98 service manuals are in my signature.http://67-72chevytrucks.com/vboard/s...d.php?t=700011

Thanks. I just wanted to find out what wire does what before I cut anything. My plug I have has a black wire but there is no black wire in my 94.

I have an extra Blue/white stripe one though.

The information is in the 94 service manuals in that post it's just not a separate book anymore.

I already read the electrical section and didn't find what I was looking for.
Looks like it will be a contest of Trial and error.
