60-66 full body wiring

[TotalNewby]

Looking for some help!

I have a 64 C20 with rear light issues. I have turn signals but no brakes, running lights. Also, I have no interior dome light, but gas indicator works. I have replaced just about everything with no luck. Starting at the back, new bulbs, new wiring harness all the way to the front, new brake light switch, new dome light and wiring, new director signal connector in the steering wheel. The onyl place I can see on the wiring diagram where dome light and rear lights meet is in the light switch connector. I am not sure what/where that is or even what it looks like????? Anyone out there got any ideas? I am stumped!!

THANKS

I'm not sure but the gauges vs the tell tale lights are different wire diagrams

Attached are some 1964 Chevy C-K 10-20 wiring diagrams I did. There a CAD file in .dwg format (in the zip file) and the same thing as a four page pdf file. Air conditioning is included as page four.

Mostly it's redrawn from the stock diagrams in the 1964 shop manual supplement. The fuse panel internal connections are shown accurately, I traced the circuits in mine. I left out devices that are not on a C-K 10-20.

If you play with the cad file it's saved as an autocad 2000 file. Each wire color is on its own layer. There is one layer on which I put all the devices that the wiring connects to. Depending on the cad program you use, you might have to play with layer colors to get a decent color print.

(I'm putting my 64 back on the road and am fixing up a lot of wiring sins I created twenty years ago. I wanted a decent wiring diagram so I decided to redraw the originals into cad format so I could edit them. The diagram for my truck is eight pages with four more pages for the stuff I have added.)

Hope this helps someone...
