While I didn't use them yet I bought a complete harness set for a 71 RR clone I am doin. 4spd. nuetral safety,engine,light and wiper harness's. I will check all of the connections after reading about this but one thing I will say is that he replaced one of the bulhead connectors for me. It was totally different than all of the others and since I spent some $$$ I wanted them to match,I gave it to him at the Nats in Ohio and he made it right...
