    Wires are correct. But green/white wire (ignition on) has only 0,4 Volts...

    Works now!
    The green/white wire had a wire break somewhere.
    Funny, since it is a new main harness.
    Removed the center console and used the wire for the shifter panel illumination. Mine is a manual, so it was not in use.

    That is good news. Great to hear, that you found and fixed the defect.
    The table in the instructions shows the function and the matching
    color-coding of the 4 wires.

    The coin cell is just for backing up the on board real time clock.
    Nothing else is powered by this battery (no display, no controller).
    After connecting the continuous power to 12V the controller starts
    to run and also the RTC runs from this power source. The battery
    is not in use during this time. The display lights up only, if the
    "ignition on" cable is fed with 12V power. 12V power on the "dimming"
    wire, when the lights are switched on, triggers the dimming of the
    display.
    Basically every function is corresponding to the OEM-clock.
    Calculating the nA current that are drawn by the RTC the battery
    should backup for over 5 years... we will see ;-)

    Thanks for making them! 😊

    As in nanoamps, an order of magnitude smaller than a milliamp. 20,000 nanoamps are needed for a single red LED for reference. If the clock stops keeping time, the coin cell can be replaced, same as any desktop computer motherboard.
