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...
