Did you find any help with this? I installed the GJ Motorsports 3rd brake light mount w/ lights on mine. I have no real skills/experience running wire or modding the interior, so I was a little timid. Here's what I can tell you...it's very easy. Here are a few tips I think are important/noteworthy:
Buy a trim removal tool kit with different sizes and bends
You'll want a second set of hands to get the wiring from the 3rd brake light into the headliner where you can grab it
The most difficult part of this is the combination of getting the wiring into the headliner and running it across the headliner to the rear pillar without being visible and without pulling down the headliner - it might sag if you loosen too much of the adhesive
After that, you just run the cabling where you've removed the pillar trim and door sills
Of course, be very patient and methodical
I installed my radio in the console. It was a pain getting the antenna cable under the carpet...I actually cut the hole in the carpet near the console (where it would be covered by the console trim) and then slid a t-square under the carpet and ran a fish tape on top of that to keep it from getting hung up.
I hope this helps. In retrospect, I wish I would have taken video. I don't have any great photos to share either, unfortunately.
