MM612 Wiring?

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.
