Installing A 3rd Brake Light Pulser In Your 2010-2013 Ford Mustang

The first mod we did on our new 2013 GT project car was Webelectric’s plug-in 3rd brake light pulser for 10′-13′ Ford Mustangs. This is an extremely easy and fast install for those of you who aren’t really comfortable taking things apart. Simply remove the trunk lid liner and plug the small harness in. Simple as that! You can find the part on our store by following this link:  Webelectric Brake Light Pulser for 10′-13′ Mustangs

Tools Needed:

Flathead screwdriver

First step is to remove the trunk lid’s felt liner. This liner is held on by a bunch of plastic clips, use the flathead to remove the clips gently as these will be used to replace the liner when the install finished.

After removing all the plastic clips, this is what you should see. Be sure to pull the emergency trunk release through the liner’s opening.

Next, remove the plug that powers the 3rd brake light.

Clip the pulser harness into the car’s plugs. You’re done!

Before reinstalling the inner trunk liner it’s a good idea to have someone put their foot on the brake to ensure the pulser is working properly. After you’re sure it’s working as intended, reinstall the trunk liner and the clips holding it on. Simple as that!

Below is an animation of how the pulser works. Please note that the light will only flash if you’ve been off the brakes for over 15 seconds as to not distract drivers in stop and go traffic or at a light.

Installing Webelectric’s 05′-09′ Mustang Plug-In Sequential Turn Signals

In this writeup we will go over the installation process of our very popular 2005-2009 Mustang Plug in Sequntial kit. Installation is very simple and requires only a couple of basic tools.

Tools Required:

  • 7/16″ Deep Socket
  • Flat head screw driver

First you’ll want to remove the black trim panel from inside the trunk area. Start by removing the twist off screw and push pin as circled below. Use the flat head screw driver to gently pry out the push pin. Repeat on the other side of the vehicle.

Next use your flat head screw driver and remove the two push pins as shown below. Again, gently pry out the pins to avoid any damage.

Take your 7/16 deep socket and remove the three nuts located on the inside of the trunk as shown below. These nuts hold the tail lamp onto the vehicle.

Once you’ve removed all three nuts, you are ready to remove the tail lamp and harness from the vehicle. Depress the tab on the grey harness plug and separate the connectors.

Now, gently pull the tail lamp away from the body of the vehicle and work the harness grommet out of its location using the flat head screwdriver as shown below. Once its free, pull the entire tail lamp and harness completely out.

With the tail lamp out from the vehicle, place it on a flat work bench and begin removing the light sockets by turning them counter-clockwise. You must also remove the socket for the reverse lamp. Finally, the harness is attached to the tail lamp with a white push pin. Remove it gently and free the harness from the tail light.

At this point we are almost done with the first side. Pull the bulbs out of the OEM harness and plug them back into the sequential harness. Before you re-install the new sequential harness, it is important to note the correct position. Each socket is pre-labeled with the numbers 1,2,3. Socket 1 should be installed in the inner most lens, socket 2 in the middle lens, and socket 3 on the outermost lens.

The orientation for the driver’s side tail lamp is shown below:

The orientation for the passenger side tail lamp is shown below:

The new sequential harness contains the white push pin. Remember to place it back in to secure the harness to the tail lamp.

To finish up the installation, re-route the harness with the grey connector through the body of the vehicle and plug it back in. Then, secure the black grommet and re-install the tail lamp. Re-attach the (3) bolts holding the tail lamp to the vehicle. Once you have completed the installation on the opposite side, place the black trim piece in place and re-attach the plastic push pins to complete your installation.
