Help! Alt wiring problem

Thanks for the replies.

Here is the question that I really need answered. We have the "newer" regulator not the mid 60's style. This regulator has the triangle connector. We have the two field alternator with a green wire to one field and a blue to the other. I have a blue wire connected on the same harness already connected to the A/C compressor. Should the flat blue connector going to the field connector on the alternator have one or two wires on it?? There is a second wire there that is not connected that looks like it can go to the alternator, but I do not want to connect it if it shouldn't go there and make a short that can blow out my alt/reg.
