i just bought a 98' bonneville ssei. i took the factory radio out and tried hooking up my 880 just to see if played and it turned on but nothing came out of the speakers??? i previsouly owned a 97 grand prix gt and used that wiring harness to hook my 880 up in my bonny...so idk if that is why( need a different harness?) but i also noticed on the back of the factory radio a single orange wired harness. what is that? i no i need a antenna adaptor and was wondering if there is a way that i can mount the cd plyer flush?
