In this edition of writeups we go over the process of installing a Bixenon HID kit on a 2009 Mustang GT. This very popular modification was easy to install and required only a 10MM socket.
- 10MM Socket
- Socket Extension
First take the wiring harness and position it on the passenger side near the fuse box cover. A majority of the connections will be made in this location.
Run the longer side of the harness over to the driver’s side of the vehicle. It is not important to tuck it away at this point.
Go back to the wires laid out on the passenger side. You’ll see two O ring terminals. You may have to push back the wire cover but you’ll see one is red and the other is black.
Using a 10MM socket, remove the bolt located on the inner fender. This is the location where you’ll connect the black ground wire with O ring terminal. Slip the O ring over the bolt as shown below and re-install the bolt.
Remove the cover on the fuse box located under the hood. There is a 10MM bolt circled in red below. Attach the red power wire with O ring terminal to this bolt. This is your power source.
The picture below shows our red O ring terminal power wire attached.
Next, you’ll want to remove the stock passenger side bulb. Simply turn the bulb counter-clockwise and it will come undone from the headlamp housing. Once you have the bulb removed, you’ll need to disconnect it from the stock harness. Use your thumb and press in the tab as shown below. While pressing the tab, gently pull the bulb away from the harness.
Take your new HID bulb and install it in the headlamp housing by turning it in clockwise.
Now, we’ll be connecting the H13 headlight plug from the HID harness to the stock passenger side harness as shown below. Simply plug the two connections in.
One of the last few steps for the passenger side is mounting your ballast. The picture below shows where we placed ours. There is more than enough space to drop in the ballast. Do not zip-tie it or bolt it in place just yet. The StangMods kit comes with both zip ties and brackets with hardware to mount your ballasts.
To finish up the installation on the passenger side, there are three plug-in connections that need to be made. Each of these connections are polarized; meaning they can only be plugged into each other one specific way. The first connection is from the bulb to the harness as shown below.
The next is the two separate plugs from the bulb to the ballast.
Finally, there is one remaining square plug from the HID harness. Connect it to the ballast as shown below.
Before buttoning everything up, check to make sure your passenger side HID bulb comes on and works.
After confirming the passenger side works, you can zip-tie all of the connections in place. Once everything is tucked away, it’ll be hard to notice the HID wiring.
Now we’ll begin on the driver side. We routed the harness over to the driver’s side following an OEM harness as pointed out in the picture below. Run the harness from HID underneath the radiator shroud cover.
To give us more space with the driver’s side headlamp area, remove the bolt holding the intake cover in place (use 10 MM socket and extension). You do not have to undo the intake completely. Simply remove the bolt and move the intake out of the way.
Remove the stock driver’s side bulb the same way you did the passenger side bulb. Undo the bulb from the harness and zip-tie the stock harness out of the way. It will not be used. You can now install the new HID bulb.
Now place the ballast in the location as shown below. There is just enough space for the ballast to fit in snugly. You can zip tie it to the large harness to keep it in place.
Next you’ll connect the driver’s side ground to the bolt on the inner fenderwell as shown below.
Finish up the process by making the same three plug-in connections that you made on the passenger side. Reinstall the stock intake and zip-tie any loose connections out of the way. This completes the full installation of your new HID kit.
