PAC RP4-CH21 Radio Replacement Wiring Interface for Select 2013-18 Dodge, Jeep, and Ram Vehicles

The RP4-CH21 wiring interface from PAC lets you replace the factory radio in select 2013-15 Dodge, Jeep, and Ram vehicles. This interface will retain factory features including steering wheel audio controls, driver information center, and the audio amplifier once the original radio is removed. The Chrysler-built amplifier only accepts a 2-channel signal, so you will lose fader control with this installation. The interface also does not retain Uconnect or your rear entertainment system.

You can also use the interface to assign a secondary function to each steering wheel control, where a short press triggers one functon and a long press accesses another. The RP4-CH21 also gives you connections for retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake, all useful if you're installing a navigation receiver.
