I have a 1952 M37, in which I installed a 6.2 from a 1985 1008. I am working on adapting the wiring harness into the M37. I am not certain on the ignition switch to starter relay hookup, and charging system. The wiring harness from the parts truck was not complete. I need the wiring diagram for the 24v system, from the engine compartment to the dash. I am leaving the 24v starter and charging system. I would appreciate whatever advise or help you could provide! Have a great Thanksgiving !
