Lumbar Operation
When the lumbar inflate switch is operated, the feed from fuse 2 in the LH or RH satellite fuse block is connected from the LH or RH seat switch pack and connected to fuse 3 in the LH or RH satellite fuse block on a P wire. From fuse 3, the feed is connected to the LH or RH lumbar pump on a P wire.

When the lumbar deflate switch is operated, the feed from fuse 2 in the LH or RH satellite fuse block is connected from the LH or RH seat switch pack to fuse 4 in the LH or RH satellite fuse block on a PS wire. From each fuse 4 the feed is connected to the LH or RH lumbar pump solenoid on a PS wire.

The earth from the LH and RH lumbar pumps is on B wires to earth header C0708 via splice joint 1.
