I snapped a couple of quick pics while I was out tinkering today. I will attach them here.

This is the control board that is in the base of the Powerdrive trolling motor. The 4 wires that are disconnected in the bottom right hand corner of the board all share contiunity with the corresponding color wire in the round connector that iPilot/Footpedal hooks into.
