Hi there!
On my '07 OB LL Bean, it was on the driver's side rear quarter panel. I took the lower trim off, and there was an unused plug waiting for my harness. Very nice. I routed the harness under the trim through a rubber grommet in the trunk pan. I did trim on the foam spare tire well cover to give the harness a bit of room, if I remember right, but it wasn't a big deal to get it like I wanted it.
