I'm having a hard time finding information on your vehicle. I'm guessing it's because of the classic nature of it, and there just is not of them left. Personally, I think it's cool as hell, but that's where I am at here. In the diagrams down below I am sending you everything I can find on the connections and testing of your vehicle's stater/starting system. Please go through the information and get back to us with what you are able to find out.
