I've seen several people on here post installs of these and mine was super easy install for cheap

cheap as in 7$ :thumbup:
Gentex auto dimming mirror with temp and compass.
Snagged this out of a 98 Chevy Tahoe with the temp sensor from PNP for a wopping 5$!
The thread I followed was from jeepforum and zachjf did an awesome job showing how to do it. Anyone with basic wiring ability should be able to do this install with ease.
Here's the thread:

The only thing you need to make this work is the mirror, temp sensor, and the plugs that match the mirror and sensor. I grabbed two sensors just in case

The stock mirror is on the left Gentex mirror on the right

This is the plug for the sensor.

This is the 7 pin plug for the mirror.
Next just make a harness from a ground a switched power( I did mine to the cig lighter) and two wires from the sensor to the mirror.
Mount the sensor somewhere out of the elements and away from engine heat.( mines in the bumper on the divers side.) Run your wires and you're done. Now you will never get lost again........ :laugh2:
