PAC RP4-CH11 Wiring Interface for Chrysler

Product Overview

Keep selected factory audio features when you replace the original radio with an aftermarket head unit using the PAC RadioPro4 RP4-CH11 wiring interface. It retains factory steering wheel controls, the vehicle entertainment system, and the factory amplifier in compatible vehicles, while providing data-bus output signals for functions such as retained accessory power and reverse trigger.

Use this interface in select Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles with MSCAN or LSFT-CAN bus radios. It does not retain uConnect.

Why Choose This Product?

The RP4-CH11 combines radio replacement with retention of selected factory controls and audio equipment. Its output signals also provide connections for vehicle functions used by compatible aftermarket radios. For factory-amplified systems, the interface accommodates the amplifier’s two-channel left/right audio input.

Installation & Compatibility Notes

• Confirm vehicle fit: Check the make, model, year, and CAN-bus system against the compatibility list before installation.
• Set the radio dial: Select the correct radio setting before plugging the interface into the vehicle.
• Non-amplified factory systems: Connect the aftermarket radio’s front and rear speaker wires to the vehicle connector.
• Factory-amplified systems: Connect the aftermarket radio’s front outputs to the vehicle connector’s rear inputs. This allows navigation voice prompts and Bluetooth calls to be heard. The aftermarket radio’s rear speaker outputs are not used.
• Amplifier fading: Fading is not supported in the factory-amplifier application. The factory radio controls amplifier fading through data communication; the aftermarket radio and interface cannot control its fader.
