Hope I've posted this in the correct forum.

Can someone tell me what color wire in the Boxster's radio harness allows the radio to determine if the cars headlights are on?

I have installed an aftermarket combination NAV/Radio unit and everything seems to function correctly except that when I turn on the Boxster's headlights, the radio's display goes blank.

Thanks,
