- Connect the interface control input wire (white, white/red, white/black, yellow, orange or green) to the vehicle as indicated in your specific instructions.
- Connect the BLACK wire to ground (-). For best results use the same ground as the aftermarket radio.
- Connect the RED wire to switched +12V. This wire should show +12V when the ignition key is turned to the ACC or ON positions.
- Cut the necessary loop (Purple or brown) if instructed to do so, in your vehicle specific instructions, or in the printed Vehicle Install Information Guide (V.I.I.G.)
- Add the proper resistor(s), if instructed to do so, in your vehicle specific instructions.
Note: some applications, such as Nissan and Harley Davidson, require multiple resistors. We include a pack of resistors with this product for this purpose. These resistors' colors and values are explained at the bottom of the Troubleshooting section of this manual. Resistor information can also be found in the "Notes; and install details" column of the V.I.I.G.
Wire resistors according to the "FIG#" diagrams are found in the V.C.C.
Radio Connection
PLEASE NOTE: SWC input may not be located on the radio's chassis.
- 3.5mm (1/8") plug - Commonly found on chassis of aftermarket radio
- Wired connection (Blue/Yellow) - For select Kenwood and JVC radios
Blaupunkt radios with optional wired remote inputs are supported by the SWI-RC, however we do not supply any connectors or support for Blaupunkt. It is up to the consumer or installer to supply this connector. Use Vehicle Connector Chart and use VW connector as referenced. Connect the SWI-RC's blue/yellow wire to pin #11 of VW connector. The connector you obtain may come with two or three pieces, however the connector (usually green) should show pin #11 on it.
Programming The Interface
NOTE about programming: The SWI-RC can be configured for your specific vehicle automatically using the PP-SWI programmer (sold separately). This option does not require any manual mapping of the SWC button functions. The PP-SWI connects to the port located under the removable panel on the top of the interface (see illustration on first page).
If you are not using the PP-SWI to automatically configure the SWI-RC, please follow these steps to manually map the SWC button functions for your vehicle and radio.
Programming The Vehicle Version
- Press and hold programming button on the side of the SWI-RC, and turn the vehicle ignition to the ON position while still holding the button. The LED on the SWI-RC will turn on. Release the programming button and the LED will turn off.
- Press and release the programming button the same number of times as the desired vehicle version number. The LED will flash each time the button is pressed and released.
- Wait 3 seconds, the LED will flash the same amount of times as the set vehicle version number.
- Turn vehicle ignition to OFF position. Programming the Vehicle Version Number is complete.
NOTE: If you inadvertently program the wrong version number, simply start again at step #1.
Mapping SWC Button Functions
PLEASE NOTE: If you programmed the SWI-RC for version 4, refer to the section below for the mapping order of the HVAC controls. These must be mapped BEFORE the other commands listed in the Radio Function Mapping Order chart, below.
The steering wheel control button functions must be mapped in the specific order shown in the chart below. If you come across a function in the chart that your steering wheel does not have, or you do not want to map, press the Programming Button on the side of the SWI-RC. The LED will flash twice and then stay on confirming that you have successfully skipped that function and are ready to map the next button function.

Pac SWI-RC Troubleshooting Guide
- My vehicle is not listed in the identification and connection chart. If your specific vehicle is not listed may not mean that is it not compatible, but may mean we have not tested your vehicle or do not have any information (schematics) regarding your vehicle. If you are able to obtain specific information regarding your vehicle we may be able to help you to get this module working in your vehicle.
- LED flashes when trying to program the vehicle version number. Please ensure that the rotary dial is set to the proper number and not to “0”. Refer to page 2 and select a radio position before turning on the ignition and attempting to program a version number.
- No power / will not go into programming mode. Check red wire connection and fuse. Make sure interface is connected to switched +12 volts, not constant +12 volts. Make sure vehicle ignition is on.
- The Interface controls the stereo immediately without pressing any buttons on the steering wheel. During mapping, press the buttons on the steering wheel FIRMLY for 5 seconds. Releasing the button too early will cause the Interface to send out a signal even when no buttons are pressed. Also ensure that the brown loop is not cut unless instructed.
- The radio changes tracks when the vehicle is turned off or does not work when the car/truck is running. Wire a relay to provide power. Pin 86 of the relay will connect to the radio’s remote (Blue/White) wire. Pin 85 of the relay will connect to chassis ground. Pin 30 of the relay will need to connect to the vehicle’s constant 12v circuit. Pin 87 of the relay will need to connect to the red wire on the SWI interface. A standard 5 pin automotive relay (Single Pole Double Throw) should be used and can be found at most automotive parts stores.
- I am using an Axxess radio replacement interface and I have programmed the vehicle version number, when I put the module into mapping mode to map the vehicle buttons the LED just flashes steady. Wire in relay as described in #5 (above)
- When mapping the SWC button functions, it takes 5 seconds for the light to go out and it never comes back on, or it never turns off. Do the connection instructions say to connect another vehicle wire to accessory power or chassis ground? If so, test the circuit with a Digital Multi-Meter (the factory radio must be plugged in) and verify that the factory radio is providing the same output
- The Interface controls the radio whenever the steering wheel is turned (mostly late 80’s early 90’s Honda/Acura) Program the interface for vehicle version #12.
- The module is put into programming mode and once I press the Volume up button the LED turns off and does not come back on. This is normally an indication of a connection issue to the vehicle wiring. Double check the wiring with a digital multimeter to ensure the proper voltages are seen on the interface wires.
- What are the rest of these wires on the interface’s 11 pin connector?
- Green wire: (Used in versions 1, 2, 4 and 10) - 12v resistive systems normally found in GM vehicles.
- White, White/Black and White/Red wire: (Used in versions 3, 8, 9 and 11) - 5v resistive systems normally found in Domestic and Japanese vehicles.
- Yellow Wire: (used in version 5) Serial Data.
- Orange Wire: (used in version 6 and 7) Serial Data.
- Blue wire: (used in version 4) Data Output.
- My module’s LED is flashing but it is not controlling the aftermarket radio.
- Check the respective output with a multi meter.
- Dial Setting 1,2,3,4 = DC voltage pulses on BLUE/YELLOW wire (this is serial data).
- Dial setting 5,6,7,8,9 = Variable resistance.
- I am using a radio replacement Interface, an OS-4, OS-5, RP3 or C2R module, and the instructions for the vehicle version number are different from what is shown in the vehicle application guide. When using a radio replacement interface you will want to follow the instructions for the radio replacement interface and not the ones found in the vehicle application guide.
- Only some SWC buttons are working. Verify wiring instructions and configuration. Some vehicles have multiple SWC wires, and sometimes require the addition of resistors.
- Buttons do not work when car is running, only when car is not running. Perform "Mapping SWC button functions" in Step 4, but with the vehicle running.
- Resistor Pack Definitions. These are the colors and values of resistors are provided with your SWI-RC module.
