99 civic SI driving lights not working

ok, when i turn on my headlights they come on fine, but the driving
lights in the back dont light up, so at night i pretty much have
nothing lit up except the headlights, o ya the corner lights dont come
on either, also my interior dash lights (tach speedometer.. etc...)
they dont come on either, so at night, well i'm guessing my speed.
anyone know the fix/problem of this? i'v read on the forums that its
something to do with the aftermarket CD player in it, and some wire
just dangling being grounded, if this is it, anyone know what the wire
looks like? if so thanks.
