Can you post any pictures you have? It would be very helpful.I'm on my cell phone. So sorry for the brief answer. I have no idea what the switched wires are originally for. To get to them I loosened the A-pillar liner and took off the sunshade in the right side. Then you can pull down the headliner and get to the wire. It's fixed with tape and I believe it's only on cars w/o the alarm package (like mine). Hope it makes sense . If not, I have pictures
I'm installing a ThinkWare F750, and would like to tap a 12V switch power source in the general area of the microphone grill. It's nice to have the 12V constant right there, but if I can't find a switched source too, I still have to run a wire to the passenger footwell area anyway.
