20-pin Subaru/Nissan Headunit Harness with SWC (2007-up Non-Navigation vehicles)
Item Number: AHH-70-7552
Description:
This adapter is used to install an aftermarket headunit/Stereo Receiver in a 2007-up Subaru or Nissan.
Adapter includes pins to connect a steering wheel control interface module. (Pins 4,13,14)* and includes pin 19. (Pin 19 connects to the Vehicle Speed Sensor signal on many Subaru vehicles). In addition, dedicated ground and +12 Volt Accessory wires are provided to power a steering wheel control interface module.
**Pin 14 is grounded in the harness for the convenience of the installer. If this connection is not desired, cut the wire that connects between pin 14 and pin 10.
Wires are either standard color coded or labeled for a simplified installation:

Ground Wire Note: The ground wire found in the wiring harness is only for select vehicles only. Confirm that your vehicle's wiring harness has a corresponding ground wire. If no wire is present, connect the ground wire of your aftermarket head unit to the vehicle's metal chassis.
This adapter does not include the 3.5mm connector that is used to connect the steering wheel control wires to an aftermarket audio receiver. If you are using an ASWC-1 or similar steering wheel control interface, this connector will be included with the interface. If your new headunit/audio receiver has the capability to recognize steering wheel controls without an interface (Sony normally has this capability), you do not need the ASWC-1. The 3.5mm jack for connecting to the back of the new headunit can be purchased HERE.
