The C2R-CHY4 interface allows the replacement of a factory radio in select Chrysler, Dodge and Jeep vehicles with LSFT
and MSCAN radios. The C2R-CHY4 also provides a secondary output for adding an optional PAC Steering Wheel Control
(SWC) retention interface (SWI-RC, SWI-CP2, SWI-X). The C2R-CHY4 also provides data bus driven outputs such as
retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
1. A PAC steering wheel interface must be used in conjunction for SWC retention.
2. Only one of the two provided radio harnesses will be used. Remove the factory installed radio to determine the correct harness
for your particular vehicle.

used.
