Satellite Fuse Box



Satellite fuse box
Located beneath the seat, the satellite fuse box provides circuit protection for the wiring to the seat switches and motors. It also protects the lumbar inflate and deflate circuits.

The seat power relay provides voltage directly to the 40A fuse in the satellite fuse box. Voltage from this fuse feeds the seat switch pack. The 3A fuses in the satellite fuse box protect the wiring to the lumbar pump and lumbar deflate solenoid. Voltage to the 3A fuses comes from the seat switch pack.
