I may be the only person in the world crazy (stupid) enough to try to put a Mercedes turbo diesel in a 1954 ford pickup body. I am retired with too much time on my hands. The motor mounted up like it was made for the truck but I am having some problems with getting the wiring and vacuum systems working. The ford has a new EZ wiring harness that was connected to gas motor. It has a Alt power wire that goes to Bat and a Alt excitor wire that I assume will go the D+ terminal on the mercedes alt. Is that a good guess? I have heard that if the alt dash light is not functioning the alt will not charge. How does the light work into the system. Obviously I need all the help I can get. thanks
