Well, there's the problem with converting one of these. You leave the safe shores of TM wring diagrams behind, and venture out onto a sea of uncertainty. All we can do is wish you bon voyage.
However, there may be a ray of hope. There is a conversion method called, "the Roscommon method", which is well documented. If the conversion was done by that method, at least you have some documentation.
I suggest looking it up here, and comparing your wiring with the Roscommon documentation. If it's a match, you have something to go on.
I *think* the Roscommon is in the Helpful Threads sticky at the top of the forum. Good place to start looking, anyway.
As for the A/C, well, maybe you can find some documentation online. I don't think it should affect your Gen lights, but you never know....
