Remove the 3 screws holding the surround on, 2 at the top, 1 at the bottom.

Image

Gently pull the surround away and unclip the brightness adjuster.

Image

Remove the 3 screws holding in the dials, 1 at the top, 2 at the bottom.

Image
Image

Gently pull the dials towards you until you can reach around and unclip the 2 plugs. (at this stage you will lose your trip mileage), remove the unit.

Image

Remove the black surround from the dials, by removing the screw at the top and unclipping the 6/7 tabs.

Image

Turn the dials over and remove the 4 larger gold screws.

Image

Gently ease out the centre speedo dial, it its only held in place by pins, be gentle though as the pins are delicate.

Image

Lift the speedo needle over the stop pin and let it rest, either take a pic or count the number of marks so you put it back in the correct position. Now gently pull the needle off.

Turn the speedo over and undo the 3 gold screws and the battery/temp/mpg dials will come away. Now remove the temp needle, it just pulls off.

Image
Image

Take the new plasma dials and place some double sided tape around the edge. Get the new dials in place by slipping them over the battery/mpg needles and onto the stop pegs.

Image
Image

Now turnover the speedo and tape the new plasma dial on the inside of the speedo.

Image

For the fuel gauge you’ll need to remove the stop peg and again using double sided tape around the edges position and stick the new dial in place. (This is easier with the dial removed, as with the speedo, gently pull the dial up). Now put the stop peg back in, getting it back in can a bit tricky, I just had to make the hole a tad wider.

Image

Repeat the above step for the rev counter, there is no need to remove the rev or fuel needles.
Now screw the battery/temp/mpg back into the speedo. Push back in the fuel and rev gauges, making sure the pins line up. Now push back in the speedo.

Image

Screw the 4 gold screws back in and put the speedo needle back on in the same position it was removed and lift it back over the stop pin.
Now for the wiring, we are going to wire it into the larger of the two connector blocks
If you want to be able to dim them with the standard dimmer then connect the live to the Green with grey band and the neutral goes to cream with a grey band.

Image

Now we need to connect the dials back up and start the car so it gets up to temperature, once its there push the temperature needle back on so that it’s horizontal.
Unplug again and clip in the black dial surround making sure the cables aren’t clamped by the clips and put the little screw back in.

Image

Connect up the four connectors for the different part of the dials, doesn’t matter in which order they go. Tie wrap the extra cable and tuck it behind the speedo. Carefully place the speedo back into position and secure with the 3 screws.
Place the surround back over and connect up the dimmer plug, once back in place secure with the 3 screws.

This is what it will now look like.

unfortunately Lee these would be no good for the Altezza, one the small 3 clocks on the is200, the MPG is actually oil pressure gauge on the Altezza's. Alo the Altezza redlines at 7850 rpm if i remember correctly. was really interested myself until i noticed these differences. If Altezza specific ones can be made up im sure we could easily get a group buy interest on here, if Snowman can make them up

Right, can do a group buy for 10 for £80 delivered.
The only problem is we need a picture of the Altezza dials.
