New to me Fleetwood Arcadia- Power roof problme solved

OK, was solved... now another issue. Whoever installed the control unit the last time and tied into the PUP power, used a black wire from the (-) and red from the (+)side of the main wire harness. (this rig uses black as the positive and white as the negative). So when I reconnected the controller, I ran black to black and red to red which made it reversed polarity. As a result, it worked for a few cycles then stopped. So I think I fried it... Not happy...
