I had to find a location for the switch for a laser jammer. I ended-up putting it above the headlight switch, to the right of the thumb wheel that controls the left vent. The entire panel, including the vent and headlight switch just pops off. Start by tugging at the left edge closest to the door. Pull toward the steering wheel.
Disconnect the headlight switch to free the panel. When drilling the hole, use a new or sharp drill bit. On mine, I had to drill through a sandwich of wood, aluminum & plastic. To run the wiring, just pull down on the panel under the steering wheel to release it then pull it toward the seat to remove it.
