Steering wheel controls for 2004 - 2006 Subaru Legacy/Liberty/Outback

Not sure about postf-facelift:
Update me and I’ll fix up

3.5inch jack
Will need:
Wire strippers
Electrical tape
Soldering iron + solder or good wrapping skills

- from steering wheel column, three plugs connect to wheel

As this is the AIRBAG connection

Larger of the other two - find the orange/white and purple/white

A Multimeter will detect voltage drop across the two wires -> press buttons resistance changes -> each button changes resistance amount

Don’t Splice - Fully Cut - Interference issues

Straight across to A 3.5inch Stereo Jack
3 wire coming out

Ground (from stereo) -> First pin on the bottom -> Orange/White wire

First Input (from stereo) -> Second pin -> Purple/White wire
