OK, I traced back the wires for that thing...
1 wire goes straight to the brake proportioner (passanger footwell)
The other wire goes to a spot where it splices into 3 other wires:
1 goes to the gold fuse/turn signal switch thing
1 goes to the dome light wiring
1 goes to the old radio/cigarette lighter area
