I think its time to give in and buy a new wiring harness

the GM connector is a much nicer connector anyway and that is a real easy job.




looks like the classic update may come with the connectors and wiring for the wipers.. if in doubt you can always call donnie at american autowire. he is the guy that designs their kits..

I've called American auto wire several times and they are quick to answer the phone and spot on with help. As a matter of fact today I'm working on a 72 Ford truck and I'll even take a picture for this evening and post it where I have to graft in all the wires for the windshield wipers.... When I did the hot rod kit on my own stuff I converted the wire kit to Mopar so if I ever have to get a new blinker harness in my steering column it'll be plug and play...
Also this Ford truck and a 63 fairline 500 I did neither one of them had bulkhead connectors. I don't think they did factory either they just ran through a hole and firewall and want you to put caulking or something to plug the hole lol...
For my stuff I buy the solder shrink wrap connectors and a heat gun...
