The Aerpro APP090 is a primary harness designed to suit various Subaru vehicles. It allows for the installation of an aftermarket headunit without the need to remove the factory wiring plug from the vehicle. APP090 converts the factory headunit plug in the vehicle into a universal double ISO connector system. For simple plug and play headunit installation, add an Aerpro APP8 secondary headunit harness to suit your new aftermarket headunit and the two looms will connect together via the ISO connector system.

Please note:
- Harnesses vary between vehicle models, to find the correct harness for your vehicle, use the Aerpro Vehicle Selector.
- Depending on the vehicle and aftermarket headunit, installation may not be completely plug and play, a small amount of hard-wiring may still be required to complete the installation.
