Marc Haibeck has another solution to the backlight for the 1990 as well

Spoke to Marc Haibeck today. Tells me its a common problem with the 90s. He wires in a diode in the line to lift the amount of dimming for in garage and tunnel driving . Or do-nothing since those are the only times it's dim. Jim
