Pinouts and Conversion Info for MK2 Saxo Clocks

This conversion is not as straight forward to the mk1 saxo clocks, requires some wiring work but its fairly straight forward please read the entire guide before deciding if mk2 clocks are for you. This guide was made by axoc members for other axoc members, if you want to copy it onto other forums please ask for permission first.

Types of clocks

  • Saxo VTS mk2

  • Saxo VTR mk2

  • 106 Gti mk2

Fitment issues

Saxo and 106 clocks have a slightly different front facia to the AX. on mk1 clocks this was a simple job of swaping over the front facia, however on the mk2 due to the digital trip meter it is not as easy. Fitting the saxo/106 clocks with the saxo/106 front facia leaves a gap as shown below

Plugs

The plugs are totally different to the AX and Mk1 Saxo connectors, Instead of the usual array of connectors they have only 2, a yellow and a black.

The yellow ones can be sourced from pretty much any later spec Peugeot or Citroen in your local scrapyard. However some of the lower spec models may have less number of wires, fear not.. If you get 2 connectors it is mega easy to remove pins from one and fit into the other to get the required amount of wires in one connector. Just slide down the black piece of plastic and the black section of the connector pulls out from the yellow section. use a pin or other sharp object to push down the side of the pin to allow it to be removed from the connector. Now that its removed you can just push it into the other connector and it locks into place

Not a great pic if anybody wants to replace it feel free..

Pinout of AX Clocks (for reference)

ax_clocks_pinout

Extras required

  • Speedo signal feed is not fitted as standard to most ax's

Fuel sender complications

The mk2 fuel sender has a range of 50 ohms (full) to 450 ohms (empty). Due to the ax sensor having a different range, a full or empty tank causes the gauge to read a faulty signal which will then cause it to wave from full to empty.

Service light reset

The procedure for resetting the maintenance indicator is as follows:

1. Switch off the ignition
2. Press and hold down the left button.
3. Now switch on the Ignition.
4. The distance remaining until the next service will now flash.
5. Now hold the button down once again for 10 seconds.
6. The display will now read ?=0? and the spanner will then disappear.

Tech data

  • Illumination type - PLCC2 SMD (surface mount) LED's, no filters on the facia so if you fit pink leds it will look pink!
  • Micro Controller is an NEC 780826GC-026. Mileage is stored on this chip

Missing LEDs

Most clocks are missing some LED's, the ax has a low water level sensor. The saxo clocks have the provisions for the warning light but no LED fitted. For a guide on how to get get these leds working see here
