Re: Color Wiring Diagram FINISHED
 

I spent some time (a lot of time actually) re-drawing this in Adobe Illustrator so everything would be easier to read. There are a couple minor edits based on what I have found in my two trucks.

Send me a PM with your email address if you would like me to send it to you.

Re: Color Wiring Diagram FINISHED
 

I don't see the three wires to the trany. I see the one green and one black to the reverse switch. My 70 GMC has three wires, dark green and light green to the switch and the black wire I just assume is a ground. But you know what they say about assuming. Thanks for the diagram it helps a ton!

Re: Color Wiring Diagram FINISHED
 

I have a 1972 GMC suburban, and the wiring is driving me crazy. The diagrams I found on here look similar to what I see under the hood but not exactly. Also, I don't see the blue wire that is supposed to be to the oil pressure on my harness but my guage cluster does have a oil pressure guage. The engine harness actually only has 5 wires. I unplugged it and looked at the female plug on the firewall and it also only has 5 inserts. The five wires I have are the tan, dark green, purple,pink, and brown with white. Can someone chime in?

Re: Color Wiring Diagram FINISHED
 

Thank you for taking the time to make a diagram like this! if possible could you e-mail me a copy at ctoydoc@gmail.com

Thank you!!

Re: Color Wiring Diagram FINISHED
 

My 70 GMC has a mechanical oil pressure gauge that is plumbed in the block next to the distributor. And the 70 gmc has 4 headlights up front.

Re: Color Wiring Diagram FINISHED
 

Maybe that's how mine is too. There is a metal line that looks like it would go next to the distributor.

Re: Color Wiring Diagram FINISHED
 

Just a heads up I'd anyone else had the same issue. I did ground the black wire to the fire wall and when I fired up my truck this weekend the backup lights work awesome.

Re: Color Wiring Diagram FINISHED
 

Just scanned the pages looking for a wiring diagram for the 1959 GMC.
Does anyone have? I might even make a Chevy one work too...
TIA

Re: Color Wiring Diagram FINISHED
 

Does anybody have a diagram for a 57 apache? I bought a new harness with updated fuse box kit. Ive got the basics hooked up. The motor runs again. I can figure it out but a reference would make it easier.
Thanks guys

Re: Color Wiring Diagram FINISHED
 

Did a high-res version ever get posted anywhere? Also, can I assume the diagram is the same regardless of the engine?

A BIG thank you to all who posted diagrams and offered advice. I have just been through all 13 pages, downloaded and printed a heap of information all of which is worth its weight in gold. I am still neck deep on gloom over this EZ kit but it will come good soon.

Re: Color Wiring Diagram FINISHED
 

Helping my brother work on a friends Blazer, this diagram was very helpful!

One question though, what does the black and black/white fused wires go to? I see they terminate at the firewall junction, but doesnt look like they go anywhere on the cab side.

Thanks!
Nick

Re: Color Wiring Diagram FINISHED
 

An electrical circuit consists of 3 main wiring components that is live(also known as phase or main), neutral and earth(ground). To distinguish between them different countries use different color code for identification.
In India 3 colors i.e. Red, Blue and Yellow are used for 3 phase live supply, Black is used for neutral and Green or Green with yellow stripes wire is used for earthing(ground) .

Here's a Wikipedia link for electrical wiring. You can go through details and can learn different color codes for wiring in various countries.

Hello, can I get that Hi-Res copy as well? Thank you in advance mllrd269@gmail.com. Looks great, great job BTW

Re: Color Wiring Diagram FINISHED
 

In the cab those wires go to the cluster connector if you have a gauge cluster. They connect to the ammeter.
