I got the wiring harness for my radio everything works except for my accessory ignition switch. If I connect it to the yellow constant power the radio will turn on and will work without the key on. Don't want to do that want it to turn on and off with the ignition and not turn off until I open the door. Any suggestions I have the db link chd6502 and everything works when the radio is on but that means it is wired constant.
