The Rust Brown part in the photo is the cushion/bolster:

Remove the C-pillar trim and then the cushion/bolster (in that order):

You should see a harness/bunch of wires either behind the bolster or the C-pillar trim. One of those wires should be a thin black wire, no other markings... that is the remote turn on.

I think that only removing the C-pillar trim could be enough to find the wire as it has to go thru that route to get to the antenna amplifier mounted in the back of the roof. Try that...
