I'm rocking a sweet little migraine, but I think I can see light at the end of the tunnel. Here's what I figured out:
Stealing from
(here) but making the pin locations actually accurate and descriptive. I lost an hour because the pins were located backwards in the first post and I forgot to scroll down to the correct version
A. Here are the eight tabs on the mirror control switch
1 - Power (hot at all times)
2 - Instrument illumination (Mine isn't working so idk

)
3 - Right side horizontal
4 - Left side horizontal
5 - Ground
6 - Right and left side yellow wire (mirror common ground?)
7 - Left side vertical
8 - Right side vertical
Diagram of mirror switch tab layout (Looking at back of switch with the connector release tab pointed up)

Mirror wire colors:
Yellow- adjustment signal common
Orange-adjustment signal - horizontal
White- adjustment signal - vertical
Grey- heated glass
Black - negative
Red and Blue are the signal and running lights. For some reason they alternate on mine. Red is my left signal and right running, Blue is my right signal and left running. Guess something got mixed up in China.
Now I'll build a wiring harness with as such
Loom 1 (Switch)
Start---------Color-----Connection
Pin 1---------Red---------12v +
Pin 2---------Green-------Illumination
Pin 5---------Black-------Ground
Loom 2 (Right Mirror)
Start------Color-----Connection
Pin 6-----Yellow----Mirror Yellow (signal common)
Pin 8-----White-----Mirror White (vertical signal)
Pin 3------Red------Mirror Orange (horizontal signal)
Door------Black-----Mirror Black (Ground)
Ignition---Purple----Mirror Grey (Heated glass)
Right Signal-----Blue-------Mirror Blue (Signal)
Running Lights---Black----Mirror Red (Running)
Loom 2 (Left Mirror)
Start------Color-----Connection
Pin 6-----Yellow----Mirror Yellow (signal common)
Pin 7-----White-----Mirror White (vertical signal)
Pin 4------Red------Mirror Orange (horizontal signal)
Door------Black-----Mirror Black (Ground)
Ignition---Purple----Mirror Grey (Heated glass)
Left Signal-----Blue-------Mirror Red (Running)
Running Lights---Black----Mirror Blue (Signal)
I will make a single loom with the 6 common signal wires and then split it to make looms 2 and 3. I will then bring wires to the area behind my switch mounting location from the running and signal light fuses. Illumination and Ignition Power I will tap from behind the stereo and bring over.
