use a Prestige alarm system to activate interior lights when I deactivate the alarm to enter the trk.???? In other words, when I am in the truck running and I shut it off the interior lights come on and time out, With the VSM on the trk not working right, how do I hook the After market alarm system into the lighting circuit to activate the interior lights when you enter the vehicle??? There must be a way...............also I have a gen 2 (2003) keep getting ck back up aid intermittently and it will and won't work at times any ideas?? thanks red423
