interior lights when door opens

[75K5]

when I open my passenger side door, the interior lights turn on. Drivers side doesn't work, so I finally got around to pulling the switch out. It was all rusted up, and when I pulled it out the wire fell off (and into the chassis).

Any idea where this wire comes from? I can't fish it out from the compartment it's in, but imagine it gets back to the fusebox somehow.

Also, anyone have a part number for that door switch, or good location to buy it from?

Thanks,
Brian

On the side panel under the dash near the brake release lever u will see a rubber grommet and a white wire.
