Welcome

. The wire goes into the rear left (driver side) quarter trim panel (where the top of the seat belt goes into). If you have split fold down backseats, when you push the backseat down, you should see a wire loom with a wire going up to the rear left quarter trim panel. I can't confirm the color as the 1996 is supposed to be different. In addition, it is too cold for me to go out to the car and check.
