I am currently restoring an Ernie Ball MM612, and am on the hunt for a wiring diagram for it since it isn't exactly standard in any way. I am looking for something with 3 3-way switches, 4 humbuckers, 2 tones, and 2 volumes. This is a pretty old guitar so if there is anyone who knows anything let me know. I also attempted to contact support, but they said they could not help.

This is the OLP doubleneck? That wasn't made by Music Man, hence why they couldn't help you.

If you don't have any current wiring in place, you might try finding a wiring diagram for any other doubleneck and try to mimic that. I'm not sure about the humbucker colors. (If they have 2 conductor wiring that would make it easier.)

Yeah it's the OLP, I was forwarded around to a few people to try and get help. i was thinking about just doing a hunt for some double neck double humbucker wiring, or making my own

I don't think you'll find an original wiring diagram so yeah, I would just make my own. Or if it's that's not your thing, copy something else.
