Subaru Enthusiasts Car Club of the Sierras - View Single Post - looking for wire diagram for an 05 STi cluster

With CA's new law requiring you to have the headlights on when using windshield wipers, I want to re-wire the dimmer circuit on my stereo. I have an aftermarked head unit and when it is in dim mode it is impossible to see the display in the daylight.

When I turn the lights on in the daylight, I always turn the cluster lighting to max and would like to use that signal to trip a relay breaking the connection to the dimmer input on the stereo.

My hope is that Subaru used individual wires for each of the five illumination stages, much in the same way that they did for the headlight leveling positions. I am not trying to get the stereo to dim, just toggle between full bright and dim based on the brightness of the dash cluster.
