i have a 2000 pontiac bonneville and my wire harness is for a ribbon harness but i have been having trouble installing for some reason. i called around to every audio place in my neck of the woods and they say they dont work on my type of car with the ribbon harness... can someone give me some advice on what i should do?
Get yourself a new head unit and run all new wiring to it.That's what I would do,it'll be a little bit of work but in the end it will be very worth it.
