On the 124 ('87 300E to be specific), I believe the instrument illumination dimmer is supposed to control the illumination not only of the instrument cluster, but also the illumination of the climate control stuff and the window switches, speaker fader, and mirror adjuster on the center console. Does anyone have a wiring diagram and can tell me which color wire (and ideally where on the back of the instrument cluster it plugs in) it is that adjusts the illumination of the climate/center console stuff? There must be a wire that runs from the cluster (where the dimmer knob is) to the hvac/center console to control the illumination. Thanks
