I just found this GM wiring manual on the web, it seems to have to some pretty good info for wiring newbies like my self. GM made this for companies that buy GM vehicles and turn them into motorhomes, van conversions, etc. so they don't make GM look bad with shoddy wiring.

Moderators - I am not sure that this needed to be moved here, it's not really GM specific. It does have some info about GM connectors, but it also has a lot of good generic info on making wiring harnesses.
