Car Alarms: Courtesy light stays on, domelight, dash light

Question
I have a 1999 F-150 with a Code Alarm 3/4 with remote start. When I lock the truck the coutesy light and rear bed lights stay on. When driving the "Door Open" dash light is also on. Where do I look for the problem? All doors are closed.

Answer
I would start at the door trigger wire.
Make sure that 1. the domelight switch in
the dash is off.

2. make sure that your alarm is set up to detect
the dome light/door trigger as a positive triggered
system. If you have both the negative and the positive
door trigger wire installed, this is why you are
having the problem. Cut off and discard the negative
door trigger wire on the alarm. All Fords are this way.

Good luck with it.
