I Think I found where it use to be. The owner before me had a push button on and off put outside just above the pump. I believe they used the wires for the latching controller for the hot on the switch. I will order a new controller and figure out the wiring. Thanks for the help. A fox and hound is a great tool wiring problems. I was a industrial electrician for 30 yrs. Used one a many off times. Appreciate all the help from everyone. Great site for motorhome owners.
