Lol.  I don’t have the time and patience. I just want to get it running  and enjoy it. 

See if you can source a factory harness that hasn't been "improved"! That is the path of least resistance if you're not a "sparky"! ?

That's what I'm considering to do now. Hopefully I can find unmolested factory harness out there.Is there any difference between 72-73 harness? I saw this on ebay and it appears to be intact. with every ones expertise  does it look complete. Need advise before buying it. thanks

Contact Dave Irwin with your harness issues. He'll probably be less expensive than a purchase from E-bay and you'll wind up with a cleaned, fully functional harness.
