Installation Instructions

Before You Start

A. Is this product compatible with the vehicle?

• See 

Appendix A -  Known Incompatible Vehicles (page 5)  

and 

Appendix E - Identification and Connection Chart (pages 

6-7) to see if your vehicle is listed. If not, check www.pac-audio.

com for an updated list of compatible vehicles.

B. Is this product compatible with the head unit?

• Ensure that the new head unit is capable of being operated with a remote control, and that it responds to the 

remote control provided with it.

• The head unit must accept a remote control with the common carrier frequency range of 38 – 40Khz in order to 

work with the SWI-X.

Note: Certain head units will not work with the SWI-X. See Appendix B - Known Incompatible Aftermarket Head 

Units (page 5).

C. Prepare for the installation.

• If possible, install the SWI-X 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-X is working 

properly.

• Plan a general installation location for both the SWI-X LED and the control body. Keep in mind that the supplied 

wire harness is 

two feet long, and the IR harness is four feet long. 

•  Use a multimeter or approved measuring device for checking vehicle circuits.
