Not without a wiring diagram, and even then it's going to be confusing. As well you won't have any circuit protection in the event there is a short to ground. Just order a switch from any of the retailers (or ebay) and then you'll know. Or if you are in a big hurry, ask a vehicle tech (or the maintenance officer) if you can borrow a switch for a day to find out.
