They're like a wired remote control that send commands to the factory radio. If you put in a new radio, those commands go nowhere. The PAC SWI-X interface can intercept those commands and send them to a radio's remote sensor through a little infrared eye. If your radio has a remote jack (headphone-sized) in the back, the PAC SWI-JACK can be plugged into that instead.
