“Both positive and negative wires have to be reversed and jumpers on the switch do the reversal. Pressing the switch one way pushes the slide out and pressing it the other way brings it back in. If there's no control board, the motor is wired directly to the switch. The motor should run till the motor stalls in either direction.“

The camper is in the body shop having suffered the wrath of a distracted driver on a cell phone... I’ll try some more recon once I get her back...
