National speed depot wiring harness from Ebay
Form the looks of the kit it’s a universal kit. They didn’t provide an kind of a diagram for the harness?
A kit like this will require a good knowledge of an electrical system, a volt meter, soldering iron, shrink tube and a good wiring diagram.
I would contact the seller for a diagram of the harness you got or try spending a little more for a stock replacement harness.
