You unbolted the wheel from the hub using the 6 cap screws. These are not how you remove the wheel, the hub itself has one nut and a puller or other method (FAQ) will remove the wheel hub. The cap screws should not be removed. Your looking for three wires on the engine harness, purple(+), green(up) and blue(down). These should be in the actual engine harness where these enter the control box and will be extended to the bow switches with 3 added wires. BCB
