Ah Hah! So it gets mounted to the panel? In that case I could also mount it to the underside of the spare tire compartment cover? I have "L" brackets for that. Checked for wires behind the radio and in the back. I took quite a bit apart back there to remove the rear facing seat and related hardware to claim the storage space. Nothing to be found and the dealer looked up my VIN and said wiring was not preinstalled. Fortunately, I have a heated garage and a '93 965 daily driver. This is fun. I also plan to snake some power for a rear power outlet that I will probably put where the rear ashtray is. Another power outlet will get mounted in the open pocket opposite the existing lighter. Then I will be able to talk on the phone, read email on my laptop, and watch a DVD all at the same time!
