Hi,
I've installed an Alpine CD deck (CDA-9827) in my '91 GTi, and it's annoyingly bright at night. The wiring harness does have a lead for dimming the display when the headlights are on, and I've been told that this can be used to follow the adjustable intensity of the dash illumination. So, what do I hook it up to? Do I pick one of the leads of the headlight switch? Is there a place in the central wiring harness I could tap onto? Recommendations for method of tapping? References to wire color and/or the Bentley manual would be appreciated.
thanks, david.
