hi i have a 1970 mustang fast back,im keeping it as original as possible, which would be the best wiring harness to buy, thank you

Asked by: ecky
You could use this harness, We do offer original style harnesses that you would have to order individually. If you would want to go that route I would suggest calling toll free at 1-800-888-6473 and speak with a sales rep.
