Seat Power Relay



Seat power relay





Located beneath the seat, the seat power relay supplies battery voltage to the satellite fuse box. Operation of the relays is controlled by the BCU.

Voltage to the seat power relays is from fuse 5 in the engine compartment fuse box. The BCU controls the earth for the relay coils. Operating the seat power relays provides voltage to the satellite fuse box under each seat.
