Done !
Wired in an DEI electronic motion/tilt sensor, was actually pretty easy.
Wired a SPDT relay to acc./ ign. on aux. outlet + tapped constant on outlet (cigarette lighters), trigger to bcm door wire (1 amp diode). Relay works by cutting the feed when ign. is on so dome light won't blink when driving, ign. off closes circuit and sets the internal sensor. only thing is dome still lights up (when tripped) when your parked.. maybe a on/off switch someday... for 20 bucks an old relay and a couple of crimp connecters not bad.
