All good thoughts. Forcing you to "sync" the drives every time you lower them is prob not a bad idea. I just hate having a button that doesn't work. I am a what if kinda guy. As I said earlier, I could not trim my good engine with blown hose on the other, because lowering it would run the other pump dry. Prob be a winter project, if the switches work both ways. They look the same as the trim tab switches, so they prob are. Thanks again to all

It was ready to add a wire from a splice with an empty female bullet connector, to the switch. Just needed a trip to the hardware store for a screw to connect to the switch. I still don't get the thinking behind Formula not wiring it, but oh well....
