Does anyone know how the dome lights light when the doors are opened? I'm hooking up Mazda 5 blue LED sill plates that light when the doors are opened, and want to tap into the wire that controls the lights coming on, but I'm not sure where it may be. I was thinking of trying hooking into the lights, but am a little nervous about damaging the airbags in the A pillar. I don't see any plunger switches like in older cars that I have owned. Any help would be great. Thanks!
