Before You Start
A. Is this product compatible with the vehicle?
• See application guide (seperate sheet) for listing of vehicles and connection information. If not, check www.pac-
audio.com for an updated list of compatible vehicles.
B. Prepare for the installation.
• If possible, install the SWI-PS while you are installing the new head unit. Keep in mind you may need to plug in the
factory stereo to locate certain wires; therefore do not complete the head unit installation until the SWI-PS is work-
ing properly.
• Plan a general installation location for both the SWI-PS plug and the control body. Keep in mind that the supplied
wire harness is two feet long, and the 1/8" plug harness is three feet long.
• Use a multimeter or approved measuring device for checking vehicle circuits.

Programming the SWI-PS to Control the Head Unit (cont.)
The SWI-PS must be programmed in the specific order shown below. If a function is not needed, it may be skipped.
1. Volume Up
2. Volume Down
3. Mute
5. Track Down/Seek Down
6. Source
7. Preset Up/Disc Up
8. Preset Down/Disc Down
9. Band
4. Track Up/Seek Up
Example: If you have a vehicle with only 3 functions, and you want to program Volume Up, Volume Down and Source. You will do
Step 21-22 twice, the first time for Volume Up, the second time for Volume Down. Step 23 will be done 3 times to skip
Mute, Track Up and Track Down. Do Step 21-22 to program Source. After all 3 buttons have been programmed, you will
proceed to Step 24.
Step 20.
A. If the current function above is what you
need to program, proceed to step 21.
B. If the current function above is not needed,
proceed to step 23

Testing the SWI-PS
Note: For Sony head units, please refer to the note below.
Test each Heater function of the steering wheel controls. The
TEMP and FAN should work properly. When testing the audio
controls, the left LED on the SWI-PS will flash indicating it is
sending a command. If any function does not work, repeat the
programming instructions (starting from Step 11) or refer to
Troubleshooting Guide.

TEMP
Sony Head Units only!: If the Volume and Track/
Seek settings are reversed, you need to program the head
unit to reverse the input. Please refer to the radio's Owners
Manual to change this feature for the wired remote.

Appendix B: Resistor Kit
Some vehicles have a seperate wire for each of the steering wheel buttons. Use this resistor kit for the steering wheel
push buttons that do not already have a resistor network connected to them. Examples are Nissan and Harley Davidson
motorcycles.
Connect a resistor to each side of a push button and connect the other ends of the resistor all together. Connect the SWI-
PS to these resistors. On the Harley Davidson, one button can be connected directly to the SWI-PS.

By putting two or more resistor in series, you can come up with additional values. Ex. 150 + 1000 + 1500 = 2650ohms.

Troubleshooting Guide
No power / won’t go into programming mode:
• Check Red wire connection and fuse. Make sure INTERFACE is connected to switched +12volts, not constant +12volts.
• Make sure vehicle ignition is on.
The INTERFACE controls the stereo immediately without pressing any buttons on the steering wheel:
• During programming, press the buttons on the steering wheel firmly until the left LED turns off. Releasing the button too early
will cause the INTERFACE to send out a signal even when no buttons are pressed.
The INTERFACE controls the radio whenever the steering wheel is turned (mostly late 80’s early 90’s Honda/Acura).
• Program the INTERFACE for version #11.
When ever I program a new button the previous button does not work.
• You must program all buttons during programming. If you try to program another button, all previous button will be erased. You
will have to relearn all previous buttons again.
Working on a new or unlisted vehicle?
We are always looking for new vehicle information. If you’ve successfully completed the installation on a vehicle with
steering wheel controls, and the vehicle is not listed in these instructions or on our Website, contact us at
