Hi all. I am in the process of converting my van into an overnighter. Any one know how to override the dome light timer so I can keep the lights on as long as I choose? Thanks

 

Check my signature below, nobody has a clue what vehicle you have.
Ford dome light with a timer, that's controlled by BCM module with the battery saver relay. You will need a capable scanner like Foxwell NT510 Elite or Forscan to alter the duration. Setting user preference at dealer's level, that's called coding. Can't guarantee if it can be changed until the scanner is plugged into your obd2 port.
