    Can anyone tell me if between '97 and '00 the dashboard wiring of the 550 was changed radically? I have a workshop manual CD and I was looking at the connectors that plug in the instrument cluster, and below the dashboard I could see two big white connectors containing two rows of about 20 wires each. If I compare the pictures and diagrams from my workshop manual I cannot understand how it works - there are supposed to be three connectors labelled "A", "B" and "C" on the manual, which go into the instrument panel. Each has specific color-coded wires (I was looking for the wires used by the ASR and by the electronic suspension to feed warning lights into the dashboard). However I could not find the same layout and I could not find the same wire color combinations.

    Can anyone help? If you have a diagram for the '00 model it would be great.

    The diagrams particularly for the 550 are notorious for their innaccuracies. The 550 diagram is so bad we often did not use it because it led in so many wrong directions. The factory knew and always promised to fix them but to a great extent we are still waiting.

    I am still trying to figure out how on earth the Motronic system runs the windshield wipers.


    Good luck

    Darn... have you perhaps managed to figure out which wires are actually responsible for sending the following signals into the dashboard: ASR active, adjuastble shock absorbers warning light, speedometer, odometer, rev counter? If at least I could identify the wire colors it would be helpful, I think that the wires for all these functions are very close together.
