A. Is this product compatible with the vehicle?

• See application guide (seperate sheet) for listing of vehicles and connection information. If not, check www.pac­audio.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 work­ing 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.

Wiring Connections

Note: Only 3 wires will be used during installation. Only GM vehicles programmed for version #4, will use 4 wires.

Step 1.

Connect the BLACK
wire to ground (-).

Verication: Wire
or location registers
a constant (-) when
probed.

Step 3.

Connect the appropriate interface wire (WHITE, YELLOW, ORANGE or
GREEN).

• Refer to the Identication and Connection Chart. Locate the vehicle and
note the SWC wire color in the “Interface Wire Color” column.

• Note the vehicle wire color and location information in the “Identication”

column.
Note: You will only connect ONE of these wires. The other 3 wires will not
be used. Cut and insulate the unused wires.

• Connect the wire as indicated in the chart.

Step 2.

Connect the RED wire
to switched +12V.

Verication: Wire reg­isters +12V when the
ignition key is turned
to the ACC or ON posi-

tions.

Step 4

If necessary, perform the following operations as indicated by the notes in Identication and Connection Chart.

Step 4a.

Connect the BLUE
serial data wire.
Connect this wire
ONLY on GM
passenger vehicles (no
trucks or SUVs) with
airbags AND steering
wheel heater controls.
For all other vehicles,
cut and insulate the

BLUE wire.

Note: Step 4a is for vehicles made by
General Motors that are programmed
for version #4 only. If no connections is
necessary, proceed to Step 4b.

2

Step 4b.

If instructed by the

Vehicle Application
Guide, cut the

BROWN wire loop and
insulate both halves.

Step 4c.

If instructed by the
Vehicle Application
Guide, cut the VIOLET
wire loop and insulate
both halves, or place a
resistor in-line of wires.

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 ash 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.

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 SWI­PS to these resistors. On the Harley Davidson, one button can be connected directly to the SWI-PS.

06-14-07

47 = yel, vio, blk
100 = brn, blk, brn
150 = brn, grn, brn
560 = grn, blu, brn
1000 = brn, blk, red
1500 = brn, grn, red
3900 = org, wht, red
5100 = grn, brn, red

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 rmly 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
