Installing Starkey Products Lower Valence Foglight Kit 2013 Mustang GT

The write up below goes over the installation process of Starkey Products lower valence foglight kit for all 2013 Mustang GTs. Our project car got some updated looks in the way of a Boss 302S grille a few weeks back. While we loved the factory LED foglamps, we’ve never been big fans of the upper grille mounted lamps. In removing the factory grille and LED foglamps for the Boss 302S grille we knew we’d eventually install foglights in the lower valence. The complete kit by Starkey Products makes the perfect upgrade for owners looking to do the same. Follow along as we go over the installation process and finished product.

Tools Required

  • Jack or vehicle ramps
  • Flat head screw driver
  • Plyers
  • Electrical tape
  • 7MM & 8MM Socket/Wrench

The hardest part of the installation process is removing the factory bezels. Removing your Mustang’s front bumper is not required but will make the job much easier. The first step was to get the car in the air so we had more working space. We started on the passenger side and placed the jack under the front control arm.

Once the car is in the air you’ll want to remove the undertray splash guard. There are (17) screws that need to be removed using the 7MM & 8MM socket. Once these screws have been removed the splash guard can be set aside. You now can gain access to the foglight area.

The bezels are held to the car with (5) tabs as shown below. These are fairly hard to remove and it will take some force to get them off the car. Take your time, start at the top and work your way down. It makes it easier to depress the tab as you are pulling on the bezel. Eventually it will come off.

Once you’ve removed the bezel the hard part is over. You are now left with an opening in your bumper that will be replaced with the new foglight/bracket.

The next step in the process is to install the new foglight bezel. Secure the new bezel to the car using the tabs. Push the bezel onto the tabs to lock it into place. You should hear it click to know when its secured. The kit includes (4) screws that secure the bezel onto the car. Install those using the flat head screwdriver or socket. On the passenger side, the windshield washer fluid reservoir makes things a little tight. Removing the bumper will avoid this problem but we chose to work around it as best as we could.


Once the new foglight bezel is installed you are ready to install the actual foglight and bracket. The process is very simple and is attached to the bezel using the supplied screws (4). There are two alignment pins as well. Line these up with the foglight/bracket and secure the screws. You are now done with the passenger side and can move over to the driver side foglight.

This completes the hardest part of the job. There is much more room to work with on the driver side and it will take less time to complete. You will need to repeat the process completed above on the driver side.

Now we are ready to make the necessary wiring connections to get power to our new foglights. Some of you maybe a bit apprehensive about doing any electrical/wiring work but trust us the next few steps are very simple and can be completed by anyone with limited wiring experience.

Power to your new foglights is taken from the OEM foglight harness. Included in the kit are quick splice taps which will allow you to get power to the new harness without cutting any of the factory wires. The first step you’ll need to do is remove the radiator cover which is held on with (8) plastic push pins.

Once the radiator cover is removed you’ll need to find the OEM foglight harness. Remove the electrical tape found near the plug and pull the black plastic wiring loom to uncover the wires going into the foglamp plug.  Do not cut the plug or any of these wires.

There are (4) thin wires going into this plug. We will be tapping into the BROWN/YELLOW and BLACK/YELLOW wires only! The other two wires will remain untouched. Using the supplied quick splice connectors place them over the wires and use pliers to clamp the connector down. You should hear it click to know a solid connection is made.

We are now almost done with the wiring. Included in the foglight kit is two wiring harnesses with male spade connectors. Simply slide the male connectors into the ends of the quick splice connectors to complete the wiring portion of this job.

Included wiring harness is connected to quick splice connectors which were installed in previous step. This completes wiring portion of job.

This is optional but we chose to wrap the OEM foglamp plug in electrical tape to ensure no moisture gets inside the plug.

Factory plug covered with electrical tape will help keep moisture out of harness.

The final step in the installation process is to snake the wiring harness down to the foglight bulb. There are numerous openings that will allow you to pass the harness down to the foglight.  Once the end of the harness is passed down all you need to do is plug it into the new foglamp and you are done! You will need to repeat this process on the driver side.
Here are a couple of quick shots we took with our Starkey Products foglight kit and Go Green LED H11 foglamp bulbs installed. We love the aggressive look of the lower valence foglights!
