Anyone's help would be great so I bought a pac harness with the steering wheel controls for my jeep jk because I replaced the stereo the stereo works great but u can't seem to get the steering wheel controls to work I know you have to sync them somehow to the pac harness but can't figure it out Its a 20123 jku if that helps
It takes 2 adapters to make it work one is the radio replacement interface and the second is the steering wheel interface. Just did mine about a month ago. If you have the correct PAC interface it has an extra connector on it that the steering wheel interface plugs into, there are instructions with the wheel interface to program it to the radio brand you chose. pretty easy took about 10 minutes to have the wheel linked to my radio.
you set the dial on the side to the number 3 for kenwood and attached the blue/yellow wire to the head unit, right?
When I installed mine, I had to reset the RP4 CH11 unit to factory defaults by pressing the reset button and then pull the power to both the head unit and the RP4 CH11 for a minute to get them to synch up.
