Item Number: 1601-8
Installing a Pioneer/Sony/Kenwood/Alpine or other aftermarket headunit in your vehicle? These harnesses maintain many of the features of your stock unit, including connecting your stock backup camera to your new aftermarket headunit. Below is the set of harnesses that connect to the factory wiring harness on a 2016-2022 Subaru (also fits the 2015 Legacy and Outback, the 2015-2023 Crosstrek and Impreza, the 2016-2024 Forester, and the 2022-2025 Forester Wilderness, which kept this generation's electronics through 2025). These harnesses will provide wire connections for an aftermarket headunit without splicing wires or cutting the factory harness.
Adding Apple CarPlay or Android Auto? Installing an aftermarket head unit is the way to get it in a WRX, Forester, Outback, Crosstrek, or Impreza of this generation - these harnesses work the same with CarPlay/Android Auto units from Pioneer, Sony, Kenwood, and Alpine. Installing an iDoing, Seicane, ATOTO, or other Android head unit? Same kit: the 28-pin harness plus the Metra 70-1761 (or our direct wire adapters) provide every connection the Android unit needs - backup camera, steering wheel buttons, power, and speakers.
128-pin harness - backup camera and steering wheel buttons
The 28-pin harness will retain:
-Backup camera functionality
-Auxiliary inputs(***Analog audio input only. USB is not included - that is step 3***)
-Reverse Gear Signal
-Vehicle Speed Signal
-E-brake Signal
-Steering Wheel control signals will be provided via a connector for the Maestro SW. Integration will require an iDatalink Maestro or similar steering wheel control integration unit. (The AXXESS AXSWC-2 is not recommended for this application - More Info) The Maestro SW will be plug and play!
The backup camera interface will provide 6 vdc to your backup camera for power and will also provide the video signal to the aftermarket headunit.
28-pin Backup Camera & Steering Wheel Harness (AHH-1601-8)$47Add to cartNeed a 3.5mm cable for your steering wheel controls? If your headunit has the capability to recognize the steering wheel controls without an interface module, such as the iDatalink Maestro, you may need a cable to connect between the 3.5mm jack on the headunit and the 28-pin harness. The 3.5mm jack for connecting to the back of the new headunit can be purchased HERE.
2Main harness + AM/FM antenna adapter - every install needs one of these pairs
The main harness connects power, ground, speakers, and illumination. The AM/FM antenna adapter is a separate piece you need alongside it - except with our ATOTO harnesses, which already include it. Pick the row that matches your new headunit:

Pioneer Direct Wire with Parking Brake Bypass (AHH-70-1761PB)$23Add to cart
AM/FM Antenna Adapter (AHH-1601-4)$19Add to cart UPGRADEThe parking brake bypass version is the same Pioneer direct wire harness, $6 more, with a Pioneer Parking Brake Bypass module already wired in. Pioneer headunits watch the parking brake wire and lock out certain screens and settings while the vehicle is moving; the module simulates an engaged parking brake so those stay available. Built in, it saves you sourcing a separate bypass module and splicing it into the harness. Everything else about the two harnesses is identical - if you do not want the bypass, take the standard one.

Installing another brand (Kenwood, Alpine, JVC, etc.)? Use the Metra 70-1761, which you will wire to your headunit's own harness - it needs the AM/FM adapter too:
Metra 70-1761 - 10-pin and 6-pin adapter$6Add to cartAM/FM Antenna Adapter (AHH-1601-4)$19Add to cart Whichever one you pick, it retains your speaker connections, power and ground connections, and illumination power. The E-brake bypass version of the Pioneer harness has the Parking Brake Bypass module built in, which defeats the "vehicle in motion" lockout on Pioneer headunits (it simulates an engaged parking brake).
3USB adapter - keep your console USB port
The USB retention harness will retain the USB port in the console.
These harnesses are 100% plug and play. No splicing the stock wiring harness.
What functionality is not retained?
-OEM Harman Kardon amplifier (see the Harman Kardon page)
-Satellite/XM radio adapter is sold separately (See detailed listing here)
-OEM Bluetooth microphone
