Optional Connection
*The battery pack should be the last connection made.
*Fuse or circuit breaker protection and power switch or power relay are required to be installed between the speed controller and the battery pack.
*Power switch/relay and fuse/circuit breaker connects to the red wire between the speed controller and battery pack. The fuse/circuit breaker should be as close to the battery pack as possible.
*The two thick red wires are connected together inside of the controller so it does not matter which thick red wires go to the battery pack or motor.
**Requires standard 3-wire throttle to operate.
