This is not the first generation WRX to have a spot in the rear bumper for a rear fog. As with previous generations, USDM vehicles have a plastic cap which plugs up the hole where it would go though. This also fits the 2013+ Crosstrek.
If you want to add a genuine Subaru JDM rear fog light to your 2015 WRX / WRX STI, just order this kit. All mounting hardware is included. Optionally, we can add T tap connectors, a pre wired extension, and modify the OEM harness it comes with for ease of installation.
You can install this to come on with your parking lights OR wire it up to come on as a 4th brake light.
OPTIONAL SubiSpeed Quick Connect Plug and Play Harness
This harness speeds up the install process for the JDM OEM rear fog lamp, SubiSpeed F1 Fog Light, GCS Rear Multifunction Light, and GCS CS Style Rear Fog / F1 Brake Light. 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. 3 extensions allow you to connect the aftermarket fog / F1 lights.
Includes 1 harness (only 1 required per vehicle) and 3 terminals.
Black - Ground (-) - Connect to gray wire on Subaru harness
Red - Parking / Running Light (+) - Connect to red wire on Subaru harness to use as a parking / fog light
Yellow - Brake Light (+) - Connect to red wire on Subaru harness to use as a brake light
NOTE: You have to choose one function OR another. You CANNOT connect to to BOTH the red and yellow wires on this harness at the same time.
OPTIONAL Fog Light Wiring Splitter / Extension
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 driver 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.
- Extension with male and female ends
- Fog Light Splitter
The plug for the female end is not pre-attached so that the wires can easily be run through grommets in the firewall area.
Optional OLM LED Bulb
For those obsessed with LED lighting technology and bright lights, the OLM replacement bulb is sure to satisfy. This low current draw, high output bulb will give this housing a crisp red appearance when lit.
This bulb is backed by a 1 year warranty.
Installation is simple. Follow the diagram for installing the housing. This is an actual diagram from Subaru.
Use the driver's side tail light harness to provide power to the JDM fog light. The following lists which wires on the tail light harness you can use to tap for a power source.
- Black Wire - Negative
- Black Wire w/ White Stripe - Positive for fog light
- Brown Wire - Positive for brake light
Wiring this to the tail light for use as a fog light will result in the light being on whenever the parking lights or low beams are on. There are grommets under the carpet which are covered with little stickers which you can use to pass the harness from the outside of the vehicle to the inside.
