cluster install is complete pending a few pictures... ac controls coming soon!


No longer doing AMM. They want $13 per month (they really should list that on the sign up page) and I dont see it being worth it unless there are enough ppl who would be interested... lets say 5 people

In this How To I used a MSP gauge cluster. The 2001+ DX/LX and the 99-00 protege have a green film on the gauges but the same method can be applied. Now let's get busy!

Tools Needed: Flat head, phillips head, small set of phillips heads, scissors, marker, olfa blade, needle nose pliers, 12v power supply, tin snips, hot glue, stapler, wire strippers, and lots of patience...

Things to Buy:

Total Time (cluster): 6-7 hours
Total Time (AC): 1-2 hours

Total Cost: $40 (blue LEDs, white LEDs, red LEDs, sandpaper, transparencies, wires and connectors)


How To: Blue Gauge Cluster
Chapter 1 - Remove Gauge Cluster
Time: 5 min

1) Set steering wheel to the lowest position
2) Unscrew 2 small screws on the black gauge surround
3) Pull off gauge surround and set it aside
4) Unscrew all of the screws holding the gauge cluster in place
5) Place a towel down on the steering column to avoid scratching it
6) Pull out the gauge cluster from the top first until you can reach/see the connectors.
7) Disconnect all of the connectors from the back.
8) Pull out the gauge cluster being careful not to scratch anything
9) Take cluster inside to a comfortable place to work

Chapter 2 - Gauge Disassembly
Time: 1hr 30min

2) unscrew the 4 gold screws on the back of the gauge assembly that hold on the plastic cover
2010-07-15210015.jpg


3) remove plastic cover by unsnapping the 4 tabs.

4) unscrew the gas/temp gauges (6 silver screws) on the right side of the circuit board as shown
2010-07-15210641.jpg


5) pry back the 2 silver tabs for the speedo using a flathead. (try not to scratch the circuit board)
2010-07-15210715.jpg


6) pry back the 2 silver tabs for the tach using a flathead.
2010-07-15210730.jpg


7) unclip all the black tabs holding on the black gauge surround. (there is no reason to remove the clear plastic on the front as this comes of with the gauge surround. Use a flathead screwdriver and gently push each tab through. Once you get most of them out you should be able to just pull it off.
2010-07-15212116.jpg


8) pull out all three gauges. The gas/temp will come out easy. The speedo and tach you may have to flip over and push the silver tabs through the circuit board.
Be very careful while removing these. Needles will break.
2010-07-15212543.jpg


9) each gauge has a clear plastic on the back side as shown we will need to remove this in order to sand. If you take off the needles it is very hard to recalibrate, plus needles break. But if you feel comfortable go ahead and remove the needles using 2 spoons. However this tutorial is not following that process.

10) On the speedo gauge using a pair of needle nose pliers and tin snips very very carefully cut the plastic at these first 2 locations.

11) Hold the gauge in your hand as shown to keep pressure off the needle.

2010-07-15213529.jpg


12) Then using the needle nose pliers snap this part of the plastic off. (it took me a good 30 min of slowly breaking pieces off before I finally got it) we are trying to get the plastic to a point where we can just slide it out.
2010-07-15213418.jpg


13) Once you have a clear path for the plastic to slide off flip the gauge over and unscrew the 2 small black screws
2010-07-15213716.jpg


14) Slide off the clear plastic
2010-07-15214810.jpg


15) Screw back in the 2 black screws to keep the needle from bouncing around
2010-07-15214826.jpg


16) The other 2 gauges are a lot easier. Starting with the tach cut the plastic in the 2 bottom places marked and snap the top piece off with the pliers.
Warning: plastic will shoot out very fast so watch your eyes.
2010-07-15212558.jpg
2010-07-15215208.jpg


17) The gas/temp gauges are the most sensitive so you can either not break any pieces off or snap off the 2 pieces at the top and bottom that cover the H and E.

18) Now you are ready for sanding!

Chapter 3 - Sanding
Time:1 hr 30 min

Be extremely careful not to apply any pressure to the needles. In the process of doing this I broke my temp needle and my gas needle. I had to buy a new cluster (60-100 bucks on the forums if you can find one). All the pictures you see here are from my 3rd gauge cluster…. 3rd times a charm!

1) start with the speedometer since this is the easiest.

2) Hold the gauge in your hand or if you feel confident to not break the needle place part of the gauge on a flat surface (avoid placing the needle on the table)

3) Using 220 grit sand paper start sanding away the white and orange coating on the back of the gauge face until you see black. It would be ideal to do this on a light table so that you can tell if you have revealed all the numbers and dashes. Otherwise every once and a while hold the gauge up to the light to check your progress. You can use a lower grit sand paper if you want, I have tried 40 grit on up to 220 and it feels like 220 is the safest but it is your choice.

4) now that you are comfortable with sanding these gauges move on to the tachometer and then to the hardest ones… the temp and gas gauges.
TIP: For the tough places fold a piece of sand paper around a flat head screw driver and get it that way. I have also found that using an olfa knife and scratching away at parts that are hard to get to works perfectly.

5) Clean up your mess using a paper towel and rubbing alcohol. Verify that you got all the orange off by holding the gauges up to a light.

The gas/temp gauges took me about 40min to finish. The tach and speedo gauges took about 30 min each so all in all 1hr 30 min to finish sanding… not bad


Chapter 4 - Lighting
Time:2 hr 30 min

There are 2 ways to go about this. the first way is adding blue film but using just this way creates green light (blue+yellow=green). the 2nd is using blue LEDs... I did a combination of both. You can skip the blue film if you want as im not sure how much it really helps.

1) first you will have to pick up some blue transparency. If you cant find it local order it here AOE Art World. You will only need 2-3 sheets.
2010-07-19213241.jpg


2) cut out 4 sqaures that will fit around each gauge face (12 sqaures total). you can either measure or hold it over the face and "eye ball" it.

2010-07-19221150.jpg
2010-07-19222241.jpg


3) stack up the 4 sqaures and staple them on the edge to hold it in place.
2010-07-19221411.jpg

2010-07-19222342.jpg


4) holding the sqaure up to the face using a marker mark off cut lines. make sure you go just outside the face to ensure that you cover everything. Also mark the center cut out and cut outs to go around the screw holes, gas light, etc. as shown.

2010-07-19214505.jpg


5) unscrew the small black screws on each gauge and carefully slide the blue film in to place. before you put the screws back in make sure all the blue is covering the right places.

6) for the speedometer gauge take two pieces of the broken off plastic that has a hole in it and put this behind the gauge face held in place by the 2 black screws. (no picture here sorry). the reason for this is to create a spacer. Otherwise the gauge face will sit too low and light will seep in from the sides.

7) now time to wire up some blue LEDs. I purchased mine on ebay. just type in the search https://www.ebay.com (commissions earned)
Info: these LEDs come ready to go with a pre wired resistor which converts the 12v power down to 2-4v so that the LEDs dont blow. the LEDs pictured below are 3mm and tend to not work or flicker so dont get 3mm.
2010-07-20194457-1.jpg


8) If you dont have a 12v power supply you will have to hook them up in your car to test them. or if you're feeling brave you can just go for it. As for the 8mm LEDs I purchased, all of them worked perfectly.
2010-07-20194432.jpg


9) once you have your tested LEDs ready to go it is time to start feeding them into the housing.
2010-07-20194400.jpg


10) I started with the tach side. I used 5 LEDs here as shown. Hot glue them down by putting a small drop of glue on the bulb itself.
2010-07-27195714.jpg


11) next slide over to the speedo. I used 10 LEDs here as shown. Hot glue them down by putting a small drop of glue on the bulb itself, a few of them you will have to put glue on the wires. do not hot glue your circuit board! only have glue on the white plastic.
2010-07-27195722.jpg


12) on to the last one I used 3 LEDs. glue them from the wires as shown.
2010-07-27195728.jpg


13) In this step you will wire red LEDs in order to light up the needles and the small odometer screen. https://www.ebay.com (commissions earned)

14) hot glue 2 LEDs to the tachometer silver connector
2010-08-10195844.jpg


15) do the same with the other 3 needles
2010-08-10204254.jpg


16) put 2 LEDs beneath the odometer screen

17) feed all the wires through various holes and twist all the postive wires together and all the negative wires together.

18) here is the trick to getting even light.. sounds dumb but it worked. Cut out computer paper to fit over all the LEDs. This will diffuse the light and create NO hot spots. hot glue the paper to a couple of bulbs so it wont move around.

19) test out your work using a 12v power supply to verify it looks good.
2010-07-20200539.jpg


20) This step may not be necessary. I ordered some white LED replacement bulbs on ebay. https://www.ebay.com (commissions earned) untwist the biggest 2 brown lights (194) and pop out the lights. Now the wide angle wedge bulbs are too big to fit through the hole. So first cut the plastic shield off the white plastic (see picture). then twist back in the brown connector without the bulb. next push in the wedge bulb. and lastly hot glue the cut off white piece to the tip of the bulb. since LEDs only work one way when you get it in your car you may have to untwist the brown connector rotate it 180 and then put it back in.

Chapter 5 - Reassembly / Install
Time:1 hr

1) Put the gauge faces back in place. bend back the silver tabs for the speedo and tach, and screw in the 6 silver screws for the temp/gas gauges.

2) blow out any dust that may have made its way into the gauge housing or the black gauge surround.

3) snap the black surround back in place and verify that everything is looking good.

4) for my cluster I had to unsnap the clear plastic front and clean it with windex.

5) on the back side (now that your needles are safe) pull all the wires to the bottom of the cluster and put the plastic piece over the wires. this will make it easier to take apart later if you ever have to.

7) disconnect the negative terminal of the battery.

8) pop off the fuse cover to access this part. run a ground wire from here up through the dash until it comes out behind the gauge cluster. unscrew the silver nut with a wrench, connect a circle connector to the end of your ground wire that will fit around the nut and screw it back in place.

9) pop off the side piece of the dash here. splice into the dimmer switch positive wire (green w/ black stripe) and run this through the dash behind the gauge cluster. solder the connection or tape it up good.

10) connect the postive and negative to the gauge cluster wiring you just did.

11) tuck all the wires back behind the cluster and zip tie if necessary and plug in the 3 connectors for the gauge cluster.

12) screw in the 3 screws to hold the cluster in place and snap back in the black cluster surround piece. Then put in the 2 screws to hold it in place.

13) reconnect battery terminal

14) wait until night time turn on your parking lights, take some pictures, and post them here!

This picture is before the red LEDs were in place

you now have (PICK A COLOR) gauges! So go take some pictures and post em up here for everyone to enjoy!


I take no responsibility for broken gauges or broken anything for that matter. Perform at your own risk as this is a very tedious process and things will break if you’re not careful.

How To: Blue AC Controls

Chapter 1 - Remove AC Controls

1) First remove the glove box. Open it, push in the sides at the top, gently lower it, the pull towards the driver side, and down to release.
glovebox.jpg


2) Look inside and towards the drivers seat.
Glovebox-Off.jpg


3) Locate the temperature control cable and disconnect it.
Gently push the tab in and pull the cable off the white control arm.
The push down on the black metal holder, and pull the cable surround out.
cable1.jpg


4) Next move the drivers side, and locate the vent control cable.
Drivers-side.jpg


5) Repeat the same steps to disconnect the vent control cable.
cable2.jpg



6) Next you need to pull the center panel out.
This is done by pushing the vents down, and pulling with both hands.
Pulling-Panel.jpg


7) With the center panel hanging out, disconnect the hazard signal button,
and the two connectors at the rear of the A/C control assembly.
Connectors.jpg


8) You can now remove the entire center panel.
Be careful to note how the control cables come out, so that you can put back in the correct way.
Once removed unscrew the A/C control assembly from the front panel.

thank you zapwizard for this section of the write up

Chapter 2 - Disassembly

coming soon (waiting on LED shipment)

they are bulbs behind the cluster. 194 and 174 IIRC.

what would be amazing would be to build some sort of light array that gives led lighting without the burn spots

cant wait to see your how to, GL!

not quite that easy. there is sanding involved.

to remove the red film in the actual cluster?

i posted because i replaced mine with red leds but now have 2 annoying burn spots. i was hoping your how to might/would address that

yes a little bit, it will be more of a solution to changing color though. I did the cluster you see in the pic with LEDs and i have hot spots, but now i have a solution that will give even light and will require very little wiring.
 
just an update my gauge cluster was just delivered! sucks that I work a 9-5 job... I plan on doing some work on it tonight as well as tomorrow. get excited!
 
subbing because i want to see the results. how do you plan on making the needles illuminate? blue LEDs will not illuminate the needles, you'll need either red or white hind them. same with the red/blue section of the temp know control. i put red led's behind my AC controller, and i had to add a white led behind the blue section because the red would not light it up. i can see the same thing happening with the red sections from running blue leds.
