Working on a 1967 El Camino. Taking on such a big task is a little terrifying for me. Talk about an EASY kit to install! Only hand one question and the tech line was VERY helpful. Old school customer service. They took the time to make sure my questions were answered. Great kit, awesome service. Truly Painless! THANK YOU!!!! - Brian H, 8/23/2014

I bought one of your chassis wiring harnesses and put it in my '77 Camaro. When I powered it up everything worked. When it comes to electrical, I'm a complete moron & I managed to do it without learning a thing! It's still a mystery to me. How cool is that? Great product. Thanks. - Dave George, 7/27/2009
