MMZ_TimeLord, when following your method I imagine the door sills will be illuminated whenever the dome light is on. Would you happen to know when the door sills will be illuminated in following the included instructions?

Edit - Following the wiring schematic from the service manual, it looks like that following the included instructions will illuminate a door sill when its corresponding door is open. However, the key must be in ACC, ON/RUN, or START in order for that wire to be hot. Doh, makes it useless when getting into and out of the car without the key in the ignition if that is the case.

Edit Again! - Going through the wiring schematics again, it looks like the left and right door ajar switches are grounds, and the wire I mistook for a ground is a constant hot wire. Never mind!
