Unusual, but you are wrong here. BOP is an early alphanumberic WPC. I think that BOP, Funhouse and one other are alpha WPC. Easy mistake. They really look like they should be Sys 11s.
I hope you're not serious. (and don't call me Shirley)
That was a simple to make mistake. No one lied.
Anyway, we are trying to help. Just keep in mind that free advice is often worth what you pay for it.
Check the manuals for each of your pins, look at the part numbers on the power supply board diagrams, see if they match or not.
Looks like they should swap. From Pinball Rehab website:
Power Driver Board Compatibility
◦A-12697-1 (5763-12406-00) was used in WPC-89 games from Dr Dude to mid Twilight Zone.
It has a flipper enable relay on the board.
It can be used in all WPC-89 games. On Fliptronic games the flipper relay will not be used by the game software.
