I haven't seen the inside of one....my door chimes didn't work when i got the car it had an aftermarket radio in it....didn't buy the extra harness either just made a jumper from the acc wire on the radio harness to the red wire on the extra harness in the dash beside the radio harness and everything works fine minus door chimes....key chime works
