Instrument Panel

Mosquito Shen tried a speedo unit from a scrap Citroen C2. The C2 panel has a temperature readout and all functions work without any recalibration.

Be aware that the car mileage is held both in the BSI and in the Instrument Panel, and it picks the highest of the two readings.  Unless you want your mileage indication to instantly increase, the new instruments must come from a lower mileage vehicle

will it fit? yes, but there will be spaces around the edges as the C2 instruments are a little smaller than the 1007 instruments.  In use, I don't notice the gaps, though some rubber tubing might be pushed into the spaces.

also the mounting points are in the wrong places.

so by using an old 1007 instrument mounting as an adaptor, I could use the original fixings of locating slots at the bottom and a screw at the top.

It is necessary to cut away all the internal structure of the old 1007 mounting . . . . . .

so the C2 instruments would just fit inside the 1007 mounting after cutting back the side and top mounting points.

it looks like this from the front; and now has the 1007 lower and upper mounting points.

as the C2 instrument panel is smaller than the 1007, two small bolts have been fitted to the 1007 mounting to retain the C2 instruments in position.  They do NOT screw into the top of the C2 instruments, their heads merely project in front of the C2 instruments, sufficient to hold it in place and prevent it springing forward.  The bolt heads (6BA so small) can't be seen when sat in the normal position in the car.

and now to fit the C2 instrument panel

prise off the instrument binnacle (simply lever upwards as shown above; try not to lose the spring clips). Disconnect the plug from the socket by pulling the lever back over the connector.  Don't try to force it - it comes apart quite easily once you work out which way to pull the lever.

showing the 1007 instruments lifted up out of position and the length of the connecting cable.

note that the connector on the C2 instruments is on the opposite side to that of the 1007 so a small piece of plastic will need to be removed as on photo.

fit the C2 instrument assembly on the mounting sockets and refit the single securing screw at the top.

carefully refit the instrument binnacle.

If all is well, reconnect the battery

Engine ticking over after a 9 mile journey at night - with the trafficators and sidelights operated.  The temperature gauge, shows three segments.

This should be the driver's daytime view of the instruments.

The rev-counter needle was all but invisible behind the scale - both under daytime and night-time conditions

To make this modification, the scale will need to be removed from the instruments.  Remove the white back; it just unclips.

Next undo the 4 screws (only) that screw into the white plastic holding the circuit board - if you undo the remaining two screws the LCD screen will probably fall apart, so keep these two screws in place.

Lift off the scale

The scale and background after removal from the instruments

Using a sharp knife, separate the scale from the instrument background

Remount the scale inside the back of the instruments using 8BA screws

and the finished look - the pointer is now in front of the scale and more clearly visible

I also changed the orange backlight LED's to white LED's

The rev-counter needle can now be seen in daylight - and the white speedo shows up well

and can now be seen at night - and the white speedo shows up well

and now I have one in the Auto - October 2020

But note - although the C2 instruments worked without problems on the car with the RT3 radio (the one with Sat-Nav etc) - on the car with the RD3 (the standard radio), the red seat belt warning lights on the multifunction screen remained on all the time and didn't go off after a few seconds as they should.  Otherwise the new instruments worked well.
