However, I am responsible for all POSITIVE outcomes. =] This swap is very simple, just need basic knowledge and tools. You have been warned! If you wish to proceed, please continue, be safe and have fun!

After receiving about 5-10 PM's per day dealing solely with my 1998 Cobra's Gauge Cluster and HVAC controls, I have decided to write a "HOW TO" article. First and for most, I would like to clarify a few questions I have been asked. The gauge cluster and HVAC controls you will see in the following pictures or the first pictures are not aftermarket, not reverse-glo, not special edition or anything else. My gauge cluster and HVAC controls are the ones that were installed in my car from the factory.

Q. Now you might be asking, why do my gauges and controls look "bluer" or "brighter" than all of the other "stock" gauge clusters and HVAC controls?
A. I swapped out the stock "incandescent" bulbs in my cluster and controls with super bright "LED's."

Q. So whats the difference in the incandescent bulbs and LED bulbs and why does it make it appear blue?
A. Behind our clusters and HVAC controls lies a blue film (the film behind the number and dial cut outs are blue[Edit by cntchds: 94-00 have blue film behind the cluster. According to members in this thread 01 and later Mustangs have green film behind the gauges. I am unsure of what this would look like if using white LED's, but I would believe that blue LED's should let off a distinctly blue light still. I would recommend blue LED's, not white, if you wish to have blue gauges in these later New Edge Mustangs.]). An incandescent bulb emits a yellowish light (like most household bulbs that are incandescent). When you mix this yellowish light with a blue film, you get a green hue showing through the numbers of our clusters and dials of our controls. NOW, when you take the stock incandescent bulbs out and swap in their places the super bright, pure white LED's and mix it with the stock blue film, you get a BLUE hue. So white and blue = blue. Hopefully you get what im saying. That is why my gauge numbers and HVAC controls are now BLUE and not the stock green.

What you will need

7 Super Bright White LED's - Socket 194/168 (sockets are the same, just different numbers)
I bought my LED's from here. (mine are the WLED-x5 Wedge Based Bulbs)

If you have a 99-04 New Edge you will need size 74 bulbs. You will need five of them.


A T-15 Torx Screwdriver


A 2 mm (I believe that's what it was) allen/hex wrench. YOU ONLY NEED THIS IF YOU HAVE AN AFTERMARKET HEADLIGHT ****!

An 8mm Socket, Socket Wrench and a few LONG extensions. YOU ONLY NEED THESE IF YOU ARE PLANNING ON DOING THE HVAC CONTROL LED SWAP!


Step 1

Start with your untouched gauge cluster.


Remove the two T-15 Torx head screws.

Step 2
STOCK HEADLIGHT ****

"You need to pull a retainer clip outwards (away from the shaft) and then pull this **** off gently." - MustangWorld.com

Aftermarket Headlight ****

Remove the 2 mm Allen/Hex screw in the side of your Headlight **** Switch

Step 3

Once you have the **** taken care of, carefully remove the gauge clusters bezel (clusters surrounding piece). It will be stubborn more than likely but it should come out, just try not to break it! After the bezel is out, unscrew the four surrounding bolts to remove the cluster itself. They are again T-15 Torx headed bolts.

Step 4

Tilt the cluster by bringing the bottom out first. (like you would be putting the gauge faces pointing upwards)

Step 4.1

Remove the black connector that is connected into the back of the cluster. Carefully pull it straight back and out.

Step 4.2


Notice the white connector on the opposite end of the gauge cluster. Just like the black connector, remove the white connector the same way. Carefully pull straight back and out.

Step 5

Once the two connectors are unplugged from the back of the cluster, carefully pull the cluster out. (It helps if you have the wheel tilted as low as it can go). From there, flip the cluster over and notice the 5 black TWIST style sockets. Untwisting the black sockets to the left will unlock them and allow you to pull them straight out.

Step 6

Notice MY already installed LED.


To replace the bulbs with your new LED's, simply pull the stock bulb out and replace with the LED. Put all the sockets back into the holes and get ready to reinstall the cluster!

So CONGRATS, we are halfway done with the swap! See, its not so bad right!?

REINSTALLATION of the Cluster

Step 7

Start by re-inserting the white connector the the back of the gauge cluster. Do not force it in, it will go in if you have it aligned right. It will require a bit of pressure but not 100% strength lol.

Step 7.1

Then go to the opposite side of the cluster and reinsert the black connector. Rules are the same as the white connector.

Step 7.2
Reinsert the Cluster with the gauge faces pointing upwards again and slide the bottom up and back to insert the cluster in its original position.

Step 7.3
ATTENTION! I would now suggest that you reconnect the negative battery cable to ensure your newly installed LED's are all working! Once you verify they are all on and in working condition, go back and DISCONNECT your negative battery cable.

Step 8

Screw in the 4 T-15 Torx headed bolts to hold the cluster in place (be careful not to drop the bolts behind the cluster, you may not get them back!)

Step 9

ATTENTION! Dont forget about the HEADLIGHT ****! Ive done this and reinstalled everything and its annoying to think your done and then notice your missing a headlight ****! Go ahead and pull out the headlight ***** shaft to the ON position and THEN install the gauge clusters bezel.

Step 10

Reinstall your Headlight **** with your 2 mm Allen/Hex wrench or simply push your stock **** back on (i remember having to adjust the retaining clip inside the **** when I had mine so you may have to play with it)

Step 11

Reinstall the two T-15 Torx headed bolts into the clusters bezel and vwalah! or walah! or.... you get the point.

------------------------------------------------------------

So, we have no completed the gauge cluster LED swap! If you are continuing on and doing the HVAC control LED swap, now is a great time to have a coke, pop, soda, w/e... Hey, im 18 so no beer for me. =P

------------------------------------------------------------


Step 1

Here we start with a stock HVAC control head unit. If you have a DVD player, make sure you fold the face down before unplugging the negative battery cable.

Step 2

Here I undid my shifter **** so I can remove the shifters bezel and boot.

Step 2.1

Once the shifter bezel and boot is taken off of the main console, unplug the cigarette lighter.

Step 3

Continuing, unscrew the two T-15 Torx headed screws securing the bezel.

Step 4

After taking out your stereo's head unit, take your extensions as well as your 8mm (i believe thats what I used) socket and socket wrench.


Unscrew the 8mm headed bolt that secure the bezel in place inside of the dash. (It is directly behind the stereo head unit. Follow the long black plastic piece)

Step 5

YAY! Our bezel can now come off after a few pulls around the perimeter of the bezel! Like the gauge cluster bezel, be careful not to break it! The bezel will be stubborn but should come out with a bit of strength!

Step 6

Here is the long black piece attached to the bezel and the hole that the 8mm screw goes in.

Step 7

After the bezel is removed and carefully set down to avoid scratches, take your T-15 Torx screw driver and unscrew the four bolts holding the HVAC controls in place.

Step 7.1

Once the four bolts are removed, carefully pull out the HVAC control unit and look for the 2 black TWIST style sockets. (These are exactly the same as the gauge cluster sockets)

Step 8
Twist out the sockets, replace the bulbs, and reinstall.
ATTENTION! I would suggest replugging up the negative battery cable and making sure the LED's work like before. Once you verify they are working, go ahead and unplug the negative battery cable again. After doing that, reinstall EVERYTHING in REVERSE order! Reconnect your negative battery cable, pull the headlight **** and again, VWALAH! You should now be greeted with a nice blue gauge cluster and HVAC controls!

Thats it! Not to long of a job but it can be aggravating. However, the results definitely speak for themselves! Hope my HOW TO was easy to follow and you got the output you desired

I just tried to put the two spare ones pete had into my car, and while the teardown is essentially the same, even the connectors on the back are a bit different.

most importantly, the bulbs are a completely different size. check it:

I don't know what the right bulb size is yet, but I'll try and find out.
