Aft passenger heated switch, wiring outlet and wires which connect to the aft seat bottom cushion and back.
The mess of wires on the inside. I didn’t want to take apart this wire loom just to save a few ounces of wire weight. Yes, that’s called being lazy.
Pilot switch is on the right side.
Note that both switches are held in place with black RTV. Without it the switch can rotate slightly and I thought that felt weird and unsightly when the switch is rotated at all.
