Horizontal
When the seat switch is operated to move the entire seat forward, battery positive voltage (B+) is applied through the horizontal motor forward switch contacts and the horizontal motor forward control circuit to the motor. The motor is grounded through the horizontal motor rearward switch contacts and the horizontal motor rearward control circuit to the motor. The motor runs in order to drive the entire seat forward until the switch is released. Moving the entire seat rearward works similarly to moving the entire seat forward, except that battery positive voltage (B+) and ground are applied on opposite circuits causing the motor to run in the opposite direction.
