This is one of the mirrors opened up with the compass under the mount cover disconnected.

The cab harness disconnect terminal numbers;

• Lower Right terminal 1
• Lower Left terminal 9
• Upper Right terminal 8
• Upper Left terminal 16

**EDIT**
I decided the trailer wheel bearings could wait til it's somewhat above 5°F.
I re-flowed the display daughterboard interconnect on both sides, all 16 pins on the main connector, and various resistors.

This is my power pak hookup using GT150 terminals. Set 250MA current limit 12.6V from my bench supply. Ground to terminal 8 & Hot to terminal 13.

This is the mirror powered up without my calibrated resistors on the temp sensor lines.
