American Autowire kits include 20 coils of wire marked every 5 in. with the required circuit function identification, terminal lugs, and a battery crimping star.Your steel frame is a poor conductor of ground current, the connection between frame and ground wire will corrode and rust overtime interrupting the current, and ground current is 50 percent of your electrical system.
