One circuit breaker is used by the MSM to apply power to the driver seat motors The second circuit breaker is used by the MSM to apply power to the steering wheel and column motors. Battery positive voltage is also supplied at all times to the MSM through a 10 A fuse located in the I/P fuse block. This voltage is used to power up the MSM. Ground is provided to the MSM through two separate ground circuits that are connected to a common ground.
