Since it's a custom job, there's no way anyone can guess what it was for, or what it does. There's no solid GREEN wire that comes out of the back of the switch. There is a heavy-gauge YELLOW wire that goes IN to the switch; this is hot-at-all-times power that gets distributed to the different switch outputs based on the position of the key.
