you should see a motion sensor taped down inside housing. Fuse block wiring feeds it to activate recording if bumped into. Will it work?? I can see it power up just by closing door. The unit has no gps, so no display of speed like some other cams.
I went with the fitcamx, it does look oem other than exposed sd card. Recommend the fuse box power kit. No boat ride, it airlined to Chicago customs. arrived fast.

so they removed the stack switch for boards on refresh, I understand your goal. Maybe a kill switch like this on relay trigger.

been researching this also, was looking for fuel pump relay. Guess has module instead. Got all freaked out when co workers ltz was stolen in Dallas area. Didn't realize how easy these are to steal. Onstar was useless. Faraday cage or pouch is a must have.
