Install the harness
-Verify that the vehicle is off.
-Carefully remove the plastic cover around the head unit and unscrew/unbolt as appropriate. Disconnect and remove the stock headunit.
-Connect the 24-pin and 28-pin connectors on the harness to the corresponding connectors on the vehicle's wiring harness.
-Connect both black ground terminals to a screw or bolt behind the dash. Note that these terminals must make contact with a metal surface for this harness to operate properly.

Connect the aftermarket headunit to the harness as follows:
-Connect the purple wire to the back-up lamp input wire on the new headunit. This is the wire that triggers the backup camera when your car is shifted into reverse. There is no need to connect the headunit wire to the backup lamp. This harness provides that connection.
-Connect the yellow RCA connector to the backup camera input connector on the headunit
-Connect the red and white RCA connectors to the auxiliary audio input connector on the headunit
-Connect the 3.5mm plug to the "Remote wired input" plug on the back of the unit.
-Connect the red wire to the same switched 12V source that your headunit is connected to. This wire is a power wire for the AXXESS ASWC-1 UNIVERSAL INTERFACE.

Configure the headunit to use the reverse camera:
-This configuration process is different for every headunit. Pioneer headunits normally come preconfigured to accept the camera but it is possible that it must be reconfigured. This is performed by navigating to the home screen and navigating to "System" > "Camera Polarity" > "Battery"

Configure the steering wheel controls
-This installation will require the AXXESS ASWC-1 UNIVERSAL INTERFACE to properly maintain steering wheel controls. Most vehicles should be automatically recognized by the AXXESS ASWC-1. If the unit does not automatically recognize the car, reprogram the ASWC-1 by pressing the reset button on the ASWC-1 for 3 seconds, release, and then follow the instructions in the ASWC-1 installation guide.

MFD Relocation harness

Relocate your Backup camera to the headunit! (Fits 2014/2015 Subarus)

Many Subaru vehicles use the small Multi-function display (MFD) in the dash to display the OEM backup camera. We have developed a harness to allow our customers to relocate the backup camera image from the MFD to the larger navigation screen.

Important Note: After installation, the backup camera image will no longer display on the MFD. This harness will relocate the image from the MFD to the larger, headunit screen. Your backup camera will now only display on the headunit.
