USDM vehicles were not equipped with a rear fog light from the factory. They only have a plastic cap covering up the center of the rear bumper. No lamp, mounting bracket, mounting hardware, or wiring.
This GCS lamp includes the required parts to mount it to your USDM vehicle.
This unique light will increase viability at night and especially under foggy conditions.
It can be wired to light up with your parking / headlights or just your fog lights (with fog light extension harness).
JAB... Just another brake (light). Wire this GCS lamp into your brake light wiring and it will emit a bright red light when stopping. This light is brighter than the fog light function. Therefore people behind you will definitely know when you're braking versus simply driving with your lights on.
Here's a new function which can come in handy. The GCS rear fog light has a row of white lights to aid when backing up the vehicle. Additional light will help you see behind the vehicle and alert others.
Red Wire (socket) - Brake Light Positive
Black Wire (socket) - Ground / Negative
Green Wire (loose) - Running Light Positive
White Wire (loose) - Backup Light Positive
If you want to wire this so that it only comes on with the fog lights you'll find yourself using a pretty long run of wire.
We've made a quick connect kit which will split the wires to the passenger side fog light. Just run the wire under the driver's side fender liner, into the vehicle, and along the door sills back to the trunk of the vehicle. The insulated connectors will be placed on the F1 light harness and extension. Just connect them together and you'll have a functioning rear fog light.
Includes splitter and extension with two pairs of connectors. The plug for the female end is not pre-attached so that the wires can easily be run through grommets in the firewall area. To purchase this addition, click here.
This harness speeds up the install process. The stock wiring harness in the WRX / STI can be hard to crimp as the area is tight. Also owners who wish to return their setup to stock at any point and time can do so easily with this harness.
The harness has OEM style connectors on both ends which allows you to install this in-line with the factory wiring. 4 extensions allow you to connect the aftermarket fog / F1 lights.

The bumper cover does not need to be removed in order to install this product. Simply undo the fasteners at the bottom of the bumper cover so you can gain enough access to knock out the factory plastic cap.
We highly recommend covering the lens of the new fog light casing with painter's tape or something similar during installation. This will prevent scratches while you maneuver it into position.
Our video will help your through the installation process. However, for reference, the OEM tail light wiring is as follows:
If you use the fog light extension harness, the negative and fog light wires will be supplied by that harness. You will only use the OEM tail light harness for the brown wire (brake light positive).
You can wire the lamp as a solid brake light only. You would do this by connecting the fog light wire (red) on the lamp to the brown wire on the OEM brake light wire (brown). It would be dimmer than the F1 style lamp though.
While many states allow brake lights that flash and then turn solid, some do not. Please refer to your local laws pertaining to this feature.
It is not required that you hook up the brake light wiring. You can run the product as a rear fog light only.
