I won't mail anyone with the power package anything and tell them to connect it to the dome light circuit. Here's why:

The device that keeps the dome light on after the door is closed is the "Smart Entrance Control Unit". This box runs many systems including:

Remote entry
Dome light
Anti-theft
Ignition kill
Rear window defogger timer

I never want to see a post that says "Ken f-ed up my truck and now none of this stuff works". Anyone can feel free to connect anything they'd like to the SECU but it won't come from me.

The box that I'm almost finished with connects only to the 4 wires of the power window relay. It will run the windows for 1 minute after the key is shut off whether the doors are open are closed. The 1 minute may be too long and I may make it shorter after I live with it for a few days.
