Wanted to bring the ol' 90 up to date a little.
Went to the junk yard and it turned out to be 50% off day there.
Snagged a rear view mirror from a 1997 GMC Yukon (auto dim, compass, thermometer) and the temp sensor mounted by the radiator.

size comparison:

Removed the factory mirror


popped the plastic cover back on after popping the mirror out

I literally ripped the mirror off the yukon's windshield so I had some glass stuck to the metal mounting tab. pounded it on the concrete a little to break off the glass and rubbed it on the floor like a 5 year old writing on the side walk with chalk lol


found a decent spot to mount the temp sensor



ran all the wiring. (only used 4 wires- power, ground, 2 wires to the temp sensors)

my headliner has always been a little tweaked since the roof rails started leaking and warped it a little. made running the wires up front easy. (have fixed the leak since then )
picked up the permatex mirror mount kit (glue) from autozone for 7.99 and mounted the mirror


Here is the wire diagram I pulled from the GM forum

Overall $23 bucks and a few hours working at a slow pace.
Love the new mirror with auto dim/compass/and temp gauge. :trophy:
