Check out the LED Rear Fog Light for Subaru:
- Subaru LED Rear Fog Light (72-005)
Step 1: Remove the clips underneath the bumper so you can gain access to the rear fog lamp location.
Step 2: Remove the plastic piece at the rear fog lamp location.
Step 3: Replace with your new Subaru LED rear fog light. All you need to do is insert the new Subaru WRX LED rear fog light and lock the assembly in place.
Step 4: Fit the bracket included in the package onto the LED rear fog light and then mount the new LED rear fog light exactly the same way as you would the OEM version.
This is how you attach the bracket onto the Subaru LED rear fog light:
Insert the screws into the openings that are diagonal from each other. Secure the screws. Then take the fastener clip and attach it to the side of the bracket that is facing towards the driver side.
You will not need to attach a clip onto the passenger side of the bracket.
Step 5: Wiring time. This LED rear fog light kit comes with a free 7440 harness to help out with installation. You'll need to install the side with the 7440 harness downward.
Step 6: Remove the trunk carpet liner. Draw the wires up through the trunk and out through the firewall hole.
Step 7: Tap the white wire to reverse light positive.
Take the 7440 harness. Tap the red wire to taillight positive and black wire to taillight negative/ground.
Tap the red wire to the brake light positive.
IMPORTANT: This particular Subaru WRX has installed a tail-as turn module for the taillights. You can see the tail-as-turn resistor in the red square.
This additional resistor creates two issues:
a.) Whenever the turn signal is activated, the taillight function of the LED rear fog light will blink.
b.) Resistor uses up excessive power so the LED rear fog light will not be as bright.
For this reason, we cannot tap the brake light wire to the existing brake lamp. We can bypass this issue by tapping the brake light function wire to the OEM 3rd brake light.
Draw the red wire (brake light function) from the LED rear fog light up behind the trunk liner all the way to the OEM 3rd brake light. Now tap the red wire to the OEM 3rd brake light.
This process fixes the LED rear fog light blinking issue as well as makes the power strong enough for maximum brightness.
Most Subaru WRX will not have to bypass this issue.
Step 8: After you have tapped all the wires, test to make sure all the functions work properly.
If the rear fog, brake light, and reverse light functions all work, then put all the components back the same way they were removed.
Enjoy your new JDM Rear Fog Light For Subaru!
