I figured I would update on this. Last night I clipped the wires at both sides of the white connector and joined them without it. When I turned the fogs on, it blew the fog fuse. Today, I took the light out of the bumper again, made sure that everything was connected, put a new fuse in, and turned on the fogs. Both sides work when the passenger fog light is not mounted in the bumper. As soon as I go to mount the light inside the bumper, when the bare metal lamp bracket hits the bare metal bumper light mount, the fuse blows in the fusebox. I called PIAA and they said that the connector is nothing more than a connector, so that isn't an issue. The guy believes there is a short somewhere in the lamp. So, is the power to the bulb somehow electrifying the housing and lamp mounting bracket, and then when the lamp mounting bracket touches the bare metal of the bumper, it's causing a short, blowing the fuse? I decided to put some electrical tape in between the bare metal lamp mounting bracket and the bare metal bumper mounting, and both lights work without blowing the fuse. I read in a tacoma world post that some people had put nylon washers between the mounts to solve electrical surging, but this is the only info I could find on this. I am new to figuring electrical stuff out, so please forgive me on terminology and what is what.
Also, when these lights were mounted, the bumper had a brand new powder coat on it, so there was no metal to metal touching. That has since rusted away a bit and I am trying to get it all fixed. Thanks.
Link to the forum post talking about this nylon washer surge fix thing that I can't find any other info on.
