66 sm blk modified engine harness on Classic Industries question

Hi Joe, I can’t answer your questions on the Classic. I’ve used year ones harnesses and they worked out pretty well. If you get on their email list they sometimes send out discount codes and with Labor Day coming up I’m sure they will be then. Sometimes 25%. I’ve also never had to return anything to Year One so I don’t know how they are that way. From what I’ve read people say the company that makes them for Year One are supposed to be some of the best. (MH I believe). Could be all harnesses are made by one company but I thought Year One had exclusives with them.
