Don't change the wiring. A feature that's not mentioned in the instructions is that the brakes are disabled when the gear is up. Program the gear controller as explained in the instructions. Cycle the gear switch to the gear down position and plug in the retracts. Toggle the gear switch to retract the gear. If the gear doesn't go up, simply reverse each retract lead. Cycle the gear again to be sure that the transmitter switch position matches the actual gear state (up or down). When the gear goes down there will be a momentary pause and then the retract controller backs off the tension. The brakes will now function. Make sure the brake discs are not catching on the screws. Mine were not smooth so I had to slightly enlarge the three holes in the disc.
