This is kind of clever. When the brakes aren't on, the brake lights glow dimly to mimic tail lights. The brakes are on when the throttle control is in neutral. Uses the connector labeled BRK
When you push on the throttle control to go backwards, this will supply power to the reverse lights. Uses the connector labeled REV
When you pull on the throttle to move forward, this output turns on. Maybe connect it to a set of high beams or driving lights or a light bar.Uses the connector labeled FWD
