Just for posteritys sake.....here's all you need to install it.
Here's all you need to know for the wiring and zone selection and compass calibration. Super easy and took 5 mins max.
The two end wires towards the middle of the mirror are power and ground and the end two towards the outside of the mirror are the temp wires. black to black and color to color from plug to sensor. I cut off the rest.
all you need to know is the two wires on each end.

Compass Switch Functions
Push in Comp switch to turn Compass on/off.
Zone Variation
This compass must be set to compensate for the variation between true north and magnetic north. To set variation:
Turn ignition on.
Using the map below to find your geographic location, note the zone that you are in.
To select Zone, push in the Comp switch for 3 seconds until the Zone selection comes up. Release, then toggle until correct zone is found and release switch. After 5 seconds of no switch activity, display will return to normal temperature reading.
Compass Calibration
This compass automatically calibrates itself while the vehicle is driven as your route takes you in complete circles. Therefore no calibration should be required, though it may take up to an hour. A quicker method is listed below. If the vehicle's compass headings become inaccurate, the compass can be manually calibrated by:
Turn ignition on.
Zone variation needs to be changed to use in different areas of the country.
For a different Zone selection, push in the Comp switch for 3 seconds until the Zone selection comes up. Release, then toggle until correct zone is found and release switch.
To re-calibrate, hold the Comp switch for 6 seconds until a "C" is displayed. Drive your vehicle in at least 3 circles, allowing 45 seconds to complete one circle.
Temperature Function
Push in Temp switch to display outside temperature, and to toggle Temp on/off.
Push Temp switch for 3 seconds until display blinks F° or C°. Release, then toggle Temp switch to select F° and C°. After 5 seconds of no switch activity, display will return to normal temperature reading.
Ice Feature
Display will indicate "ICE" to alert driver to potential driving hazard when temperatures are below 38° F.
