Parts you will need:
St gauge pod
St gauge pod surround (optional)
ScanGuage (I have chosen scanguageII, but there are several models available)
Glue
Perspex sheet, A4 size is plenty big enough, 1.5mm thick (don't go any thicker, you will see why later in the guide)
Tools you will need:
T25 Torx
Drill, I used 10mm, 3mm, 4mm, 5mm.
Dremil or something else to cut/shape the perspex sheet
Flat blade screw driver
Stanley blade
Rule (something straight)
First off you will need to remove the dash storage compartment, this can be done by either removing the speed/rpm dials, or it can be done by prizing it off using a flat blade screwdriver. I done it with a flat blade screwdriver without damaging any of the surfaces by putting a cloth over the end.
Once removed you will have a hole like this ^^
My next step (due to buying a st gauge pod with missing part and having to wait to get my hands on another) was to position the cable. For this locate the OBD port on the right hand side under the steering wheel.
To remove this trim piece, remove the T25 Torx screw from just above the OBD plug and then the trim simply unclips. Be careful not to let the trim drop or 'yank' it too hard as the OBD plug will still be attached.
To remove the OBD plug push through from the front of the panel and release the clip either side on the rear.
Once the trim piece is removed you can now cut your hole to feed the connection cable for the scangauge through. I started by drilling a small pilot hole below the hole for the OBD plug, then drilled through with a 10mm drill piece. The hole then needs to be elongated slightly to allow for the connector to pass through (12mm wide) I used a dremil to take the extra material away. Once you have a hole big enough to feed the plug through it should look a little like this.
(Perhaps a little neater, but it is hidden when fitted)
To refit the panel to the car is just reverse of removing, only this time you will need to feed your connection wire through the hole you just made up to the top of the dash where the scangauge will be mounted. There's plenty of space to feed the wire straight up. Also note when putting the trim piece back on to make sure the rubber seal goes back over the edge that's near the door.
Now it's time to mount the ScanGaugeII inside the st gauge pod.
To remove the gauges from the pod simply unscrew the two T25 torx screws that are in the bottom of the gauges holding them in place, once removed they simply slide straight out.
(Note in the picture above there is a small part of the trim missing, yours should have this part like in the final pictures)
Once they are out I used them to make an outline on the perspex sheet, this means it should pretty much fit straight away
(sorry for bad quality pictures!)
Once marked out cut it out with a dremil (make sure you ware eye protection!) Leave a couple of mm over the lines then shave down for a nice fit.
Next I removed the 4 cross head screws from each corner of the back of the scangauge, this allows you to remove the front cover of the gauge.
This is the part were you need to position your scangauge in the pod, I found the easiest way to do this was to use 'buletack' to stick the front panel of the scangauge onto the perspex sheet, then fit the perspex sheet into place. Reposition the scangauge front on the perspex until the correct position is achieved. Once it's in place I then used a marker to mark out the screen and the holes for the buttons. (At this point I forgot to take a picture)
Before cutting and drilling the perspex sheet I made a card template to test first. So transfer the markings from the perspex onto the card. Then again hold in position to make sure it looks ok.
If it looks good to you, then cut out the holes to allow the scangauge to fit for a final check before drilling the perspex.
If this is all ok you can move onto drilling the holes for the buttons. The buttons are about 4/4.5mm in dia. I first used a 3mm drill bit, then 4mm and then went through again with 5mm. This allows the buttons to fit through and can be pressed easily.
Check that the perspex sheet fits over the scangauge
