Introduction
The PAC RP4-CH11 RadioPRO4 Interface is designed to facilitate the replacement of a factory radio in select Chrysler, Dodge, Jeep, and RAM vehicles. This all-in-one interface retains essential vehicle features and provides necessary outputs for aftermarket radio integration. It is pre-loaded with capabilities for amplifier retention and seat controls, ensuring a seamless upgrade to your vehicle's audio system.
Setup and Installation
Proper installation is crucial for optimal performance. Always ensure the vehicle's battery is disconnected before beginning any wiring procedures.
1. Disconnect Vehicle Battery
Before starting, disconnect the negative terminal of the vehicle's battery to prevent electrical shorts and ensure safety during installation.
2. Identify Wiring Harnesses
Locate the factory wiring harness in your vehicle and the wiring harness provided with your new aftermarket stereo. The PAC RP4-CH11 module will connect between these two harnesses.

5. Reconnect Vehicle Battery
Reconnect the negative terminal of the vehicle's battery. Turn the ignition to the 'ON' position to power up the new system.
Operating Instructions
1. Steering Wheel Control Programming
The RP4-CH11 interface comes pre-programmed for most factory steering wheel control (SWC) functions. If you wish to re-assign SWC functions or utilize short press/long press dual command functionality, follow the programming instructions provided in the PAC RP4-CH11 manual. The LED on the interface will flash whenever an SWC button is pressed, indicating functionality.
2. Amplifier Retention
The interface is designed to retain the factory audio amplifier, if equipped. Ensure the amplifier turn-on wire from the RP4-CH11 is correctly connected to your aftermarket radio's amplifier remote turn-on output.
3. Seat Controls
The RP4-CH11 also supports the retention of factory seat controls where applicable. Refer to the detailed wiring diagram in the product manual for specific connections.
Maintenance
The PAC RP4-CH11 interface is a low-maintenance device. Ensure all connections remain secure and free from corrosion. Periodically check wiring for any signs of wear or damage. Keep the module free from excessive moisture or extreme temperatures.
Troubleshooting
- No Power to Aftermarket Radio: Check all power and ground connections. Verify the vehicle's fuse for the radio circuit. Ensure the PAC RP4-CH11 module is correctly connected and receiving power.
- Steering Wheel Controls Not Working: Confirm the correct radio select rotary switch setting on the PAC module. Re-attempt the SWC programming steps as outlined in the manual. Ensure the 3.5mm SWC connector is properly plugged into the aftermarket radio.
- No Audio or Distorted Audio: Verify all speaker wire connections. If the vehicle has a factory amplifier, ensure the amplifier turn-on wire is correctly connected. Check the aftermarket radio's fader and balance settings.
- Battery Drain: If experiencing battery drain, ensure all connections are correct and the interface is powering down properly with the vehicle. A faulty interface can sometimes cause parasitic draw.
