20-pin Combined "Breakout"
Use this harness when you are keeping the factory radio in your Subaru or Nissan and want to add something in between the radio and the car. This combined harness will save you time and effort. All 20 pins are already connected straight through. All four speaker channels (8 wires) are longer, ready for you to cut or tap in the middles and connect to your speaker amplifier, Line Output Converter (LOC), audio processor, or other aftermarket gear.
The ground and two +12V power wires already have "T" branches connected. You can use the Red +12V Accessory line for an amplifier remote turn-on (since most Subaru factory radios don't have that signal).
Wires have the EIA-standard color-coding used by after-market car audio equipment, with printed labels (for example, "LEFT FRONT POSITIVE").
Fits all Subaru and Nissan models that can use Metra 70-7552 and 71-7552, Scosche NN04B and NN04RB, American International NWH-704, Aerpro APP091, etc., including:
For recent models with OEM Fujitsu Ten navigation, STARLINK, and any others that use Toyota-style radio harnesses, see this 10- and 6-pin combined harness
For older model years and some models with OEM Kenwood or TomTom navigation, ask me about my 14-pin combined harness
