Welcome to NECOA. That circuit feeds the parking lights (including tail), marker lights, and license plate lamp. All a brown wire. Because of the bumper removal, I would start in the back and follow the brown wire from the lamps looking for a short to ground.

I just had the same problem. It was the Lampsocket of the parkinglight left front.
