I would like to replace the engine wiring harness in my 69 c3. Looking for a good wiring diagram and Dr Rebuild was recommended. Can anyone tell me if the below linked diagram includes the engine wiring. The description says dash wiring diagram.

I have a stack of different schematics and diagrams. some I added color to, others that I bought that way. Docs is unbeatable for identifying plugs and where they go, the actual color schematics make trouble shooting easier. I would buy both of Docs diagrams for your car, and a full color lamainated schematic as well. Heres some I would use in addition to the one you found. Willcoxs' isnt color but its a good one from Lectric Limited. I also use Lectric Limited harnesses and they lay out and fit like stock. I have good luck with their switches too. I think Willcox stocks their stuff, you can ask, but I believe Ernie Bench tests alot of his products. So support willcox if you buy their stuff.

What I would do... click twice on the picture below, this will enlarge it. Then right click on the picture that opens, select copy image.
Then open your paint program on your computer and paste it in there. Next, save the file to your desktop.
This makes it nice since you can color trace any circuit and see where the wires are going. We have these for all cars 1953-1982 and use them almost everyday in our shop when we are working on a wire issue. If you trace out a wire, save it as a different file so you can keep track of it.

I tried to order a copy of the diagram and this guy sent me the following , " YES or NO: Are you or were you an NCRS member? Be Honest. Dishonest replies are cancelled. They are ! : No
I don't play games.
You know what they say ... Fk around and find out." I didn't even know what NCRS was.
A colorized version of the original GM drawings with corrections.
I scanned in the original GM wiring diagrams and then redrew them in color correcting a few mistakes that GM made.
Also added the K66 option which is the Transistorized Ignition.
I made it into a PDF as it is quite large in size (about 15,200 x 4,900 pixels) and as a PDF you can zoom or shrink it quite easily.
Also, it is free!

Jeff, You're welcome! If you find any mistakes or something that could be added let me know.
I have made a number of revisions since I first started this project.
