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.
