I looked into building these harnesses and was trying to find all of the connectors. They can still be had from a company called tyco (I believe) but the guy I was working with said if have to go through their catalogues to find them all. I got about half of them found then I have up. I had everything written down along with lengths, if I can dig it up, I'd pass it on to someone with free time, but after looking into it, I would say anything between $500- $650 would be ideal for the work that would go into one of these harnesses, which was the other reason I stopped looking, as I doubt too many people that own alltracs would be the type of people to pay that. I'm not knocking on people, I built my own with junkyard connectors.
