Brian kc0kfg | | | | | Joined: Apr 2007 Posts: 12 Junior Member | | Junior Member Joined: Apr 2007 Posts: 12 | Will this wiring diagram work with the '66 GMC 3/4 Ton truck? I have acquired a '66 Longbed 4x4, and I know there are some electrical issues that will need to be sorted through. Does anyone know who provides new wiring harnesses? Thanks for any help!
John [email protected]If you are interested in my '66, make me an offer! I also like doing work, and if you need some done, let me know! Tecnically I live in Southern California, but not for much longer, going back to the MidWest!

Factory wiring harness for '64-'66 Chevy trucks are available from bowtiebits.com, lmctrucks.com, chevyduty.com and oldchevytruck.com. I am not sure about the same era of GMC trucks. Good luck with your wiring.
