Hook everything up except the cable to the spedo,drive the truck or jackit up and run it see if it turns if not move down the line section at a time till you find the problem.The bottom end of the cable didnt have a tip they were just swedged square. I had a tool to do this but its long gone. It looked like a small press and you smacked it with a hammer. It would cut the cable and square it and I beleive it would crimp the end on the top end of the cable.
