Wiki Definition:
A diffuser, in an automotive context, is a shaped section of the car underbody which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. It works by providing a space for the underbody airflow to decelerate and expand so that it does not cause excessive flow separation and drag, by providing a degree of "wake infill". The diffuser itself accelerates the flow in front of it, which helps generate downforce.
I'm talking about those two 'fin' like pieces that hang down on either side of the exhaust pipes. If you crawl under the car you can see screws attached to them. (One screw is on the inside of the rear wheel well. I think (not sure) that they are the torx bit type of screws though.
I removed the one on the passenger side, and there's a drain plug that you can pop out. Once it's out if you look from the top (remove the brake light access pannel and look down) you'll be able to see light (and possibly the ground). I used that hole to run the wires, just remember to put the drain plug back on when you're done!
But i'm not 100% sure this would even work for your application, because I was running wires from the bottom of my car into the cab.
:/ sorry
Good luck!
