yeah it ties into the wiring harness, then uses a RF transmitter aimed at the headunit to allow the steering wheel controls to work.. ive contemplated it.. unsure still.

I believe if you own an alpine the PAC harness plugs into the backside of the deck. So it doesn't have to use RF for all head units. I'm sure it's dependent on model # but the 9887 will do the direct plug interface.
