I purchased the american autowire kit, I tried the install myself. The kit needed to be cut to size and the connectors installed. The way i saw it without the correct crimping tool great connections that I could trust couldn"t be made. I priced this tool @ 100 bucks. I had it professionally installed, the guy routed it, installed the conduit, and tucked it away very neatly. He charged me 500 for the complete install and it looks like one of the hot rod shows did it.
