White wires at the door pillar are typically the ground side of the dome/courtesy light circuit and go to the pin switch on the door jamb. As noted, these don't really look like factory wires, but it's hard to tell in the photo.
Would anyone have the pin connections or a picture of that door jamb switch? Do the wires that connect to the door jamb switch use a factory connector to go into the harness or are they connected to the harness directly?
