I'm looking for the pinout of a headlight switch for an 86 US E24.
I want to stop the OBC display light not to dim when I turn on the lights.
I'm color blind and cannot set it when it's dimmed during the daylight.

I believe that one of the wires sends a ground or hot to the lighted display.
I think that if I could disconnect that wire going to dim mode it will solve my problem.

I've looked @ the switch diagrams in the ETM but can't figure what wire does the dimming.
I know that the lights in the hazard and rear defogger and radio will not dim if this can be done.

I'm posting on E24 & Big6coupe-as well.

Thanks for any info.
