Hello I am trying to wire in the alternator on my 66 m100. The starter relay was missing also. And no wiring for both. I have a set of original from a 66 f100 but I cannot find a diagram with wire colours to know where each wire goes on alternator and starter relay. I just need diagrams hand written ur pics with wire colours please. Thank you.
