20 +12V Battery (Constant-on) Blue/Red YellowNotes:

EIA is a standard for wire colors used by nearly all aftermarket head units (HUs) and harnesses

Illumination = +12V when headlights on, otherwise open-circuit
Dimmer = variable voltage from 12V (dimmest) to 0V (brightest) [yes, backwards — not a typo], same as instrument panel lighting

* Subaru's wiring diagram shows pin 11 wire color as "LgR" for "Light Green/Red"
