Trucks Without a Center Console

If your truck does not have a center console, begin here.

• Step 1: Remove the circled rubber insert to access the screws securing the dash in place.
• Step 2: Remove the two T-20 torx screws from the top of the dash.
• Step 3: Remove the T-20 torx screw from the back of the small pocket on the right side of the dash (this screw may not always be present).
• Step 4: Remove the dash panel by gripping firmly and pulling straight out on the top portion of the panel.
• Step 5: Disconnect all harnesses from the back of the dash panel. Once disconnected, remove the dash panel from the truck.

This concludes Part One. Please proceed to Part Two.

Removing the Radio

• Step 1: Remove the four 7mm screws securing the factory radio in place.
• Step 2: Disconnect the 52-pin dock and lock connector, along with all antenna connections, from the radio. The number of antenna connections may vary based on vehicle features.
• Step 3: Remove the factory radio from the dash. (Dash appearance may vary by model year.)

Relocating the Factory Security Module

(If present; not necessary if installing a shallow mount radio)

• Step 1: If your truck is equipped with the factory security module, it must be relocated to allow removal of the lower portion of the metal support bracket.
• Step 2: Remove the three 7mm screws circled in the image and set them aside.
• Step 3: Relocate the security module to just below the plastic support beam shown in the image.

Cutting the Sub-Dash

(Not necessary if installing a shallow mount radio)

• Step 1: For 2013-2017 model years, cut here.
• Step 2: For 2018-2019 model years, cut here. More metal may need to be removed for these models.
• Step 3: After cutting, the sub-dash should appear similar to the provided image.

This concludes Part Two. Please proceed to Part Three.

• Step 1: Remove the portion of the dash outlined in red and prepare to replace it with the new PAC dash bezel.
• Step 2: Remove the 13 Phillips head screws holding the factory dash bezel onto the dash panel. Retain these screws for securing the new dash bezel.
• Step 3: To remove the factory dash bezel, flip the panel over and pull straight out from the bottom of the bezel, then down.
• Step 4: Your dash panel should now look like the image. Ensure you have retained the 13 Phillips head screws from Step 2.
• Step 5: Install the appropriate insert (Auto or Blank) into the center of the fan speed knob on the new dash panel. Choose the correct insert carefully, as changing it after installation can be challenging.
• Step 6a: If your vehicle has Automatic Climate Controls, install the insert labeled "Auto". Align the light pipe with the hole in the kit. Note: Installing this button will not add automatic climate control functionality if the truck did not originally have it.
• Step 6b: The "Auto" insert should look like this when properly installed.
• Step 6c: If your vehicle does not have automatic AC, install the blank insert. It should look like this when properly installed.
• Step 7: Insert the new dash bezel by placing the top edge in first, then sliding it up into place.
• Step 8: Secure the new dash bezel by reinstalling the 13 Phillips head screws removed in Step 2.
• Step 9: Your dash should now look like the image.

This concludes Part Three. Please proceed to Part Four.

Connectors

Detailed pinout information for each interface connector:

DIP Switches

Set the DIP switches on the interface according to your aftermarket radio brand. Set the corresponding switches to the ON (DOWN) position and all others to OFF (UP).

*Other brands include Dual / Axxera, Jensen, Rockford Fosgate.

Important: Adjust the radio select DIP switches before connecting the interface to the vehicle.

Wiring Connections

1. Set the DIP Switches on the interface according to the chart on page 10.
2. Wire the aftermarket radio harness according to the wiring connection charts for Interface Connector 1 and Interface Connector 4 on page 10.
3. Connect Interface Connectors 1, 2, and 4 to the RP4.2-CH4101 module.
4. Connect Interface Connector 3 to either the amplified or non-amplified audio output connector, depending on your setup.
5. Connect one end of the supplied LCD Display connector into the Expansion Port on the RP4.2-CH4101. Route the other end to be accessible after the factory dash panel is re-installed.
6. If installing in a truck with factory parking sensors and no factory amplifier (or if bypassing the factory amp), connect the supplied external chime speaker to the external speaker output on Interface Connector 3. Mount it where parking sensor chimes can be heard clearly.
7. Connect the SWC output wire to the aftermarket radio's wired remote input.
8. Once all connections are made, plug the vehicle connectors into the vehicle harness.
9. Reverse Camera Connection (See Fig. 2):
   • a. Connect the included RPA-16P1V harness to the 16-pin connector (Connector 3) on the back of the radio dash bezel (See Fig. 1).
   • b. Connect the Male Yellow RCA (Video Output) from the RPA-16P1V harness to the aftermarket radio's reverse camera input.
   • c. Connect the Female Yellow RCA (Video Input) from the RPA-16P1V harness to the Male Yellow RCA from the vehicle connector 1 (factory reverse camera), or to the aftermarket reverse camera's RCA video output.
   • d. Connect the red and black power wires from the RPA-16P1V to the aftermarket reverse camera's power wires. If using a factory camera, insulate these wires.
   • e. To Add Additional Cameras (Front, Blind Spot, Cargo, etc.): Use the RPA-16P5V (sold separately) instead of the RPA-16P1V harness. See the next page for details.
10. Re-install the factory dash panel. Connect the factory plugs from the vehicle into the appropriate connectors on the back of the dash panel.
11. Connect the free end of the LCD Display connector into the outermost 10-pin connector (Connector 1) on the back of the radio dash bezel (See Fig. 1).
12. If retaining or installing cameras, connect the RPA-16Pxx harness into Connector 3 on the back of the radio dash bezel (See Fig. 1).
13. Optional: For easy firmware updates without accessing the Climate Control display, connect a USB extension cable (PAC part USBDMA3, sold separately) to the USB port (Connector 4) on the back of the radio dash bezel and route it to an accessible location (e.g., glove box).
14. Once the dash bezel is connected, the LEDs for the hard buttons will illuminate momentarily, then flash, indicating initialization. They will then turn off, and the RadioPRO splash screen will appear on the LCD. Initialization can take up to 2 minutes. Once the LCD is active, proceed to the setup and testing section.

Using Multiple Cameras

With the optional RPA-16P5V harness, the RPK4-CH4101 supports up to 5 cameras. This harness replaces the RPA-16P1V. Camera 1 is reserved for the reverse camera; inputs 2, 3, 4, and 5 can be configured for other cameras. Camera input and control are managed via the LCD display's settings menu. Power and ground connections are active when the vehicle is on, supporting up to 800mA total for aftermarket cameras. For higher power needs, use an external relay. See page 13 for setup.

Setup and Testing

Verify that all screens and functions operate correctly through the 5.2" display.
