i dont have DSP and thats the problem, i can't find the wires FOR the CD changer, hence the point of the pic i posted above.i also did some snooping around as i was trying to get my radio to work again(no luck
).no clue what the first one is for.as for the second and 3rd one, think this might be the CD changer harness only because i see the bluetooth adapters strapped to it as well.
