First, you will need to remove the original mirror. This part was the only hard part for me, because I didn't realize how to disengage the mirror from the windshield at first glance. There is a small slot on the mount, that all you need to do is stick a small screwdriver in, and once you feel the tip hit something and can't go any further, Put just a little more pressure on it, and it will release the clip and the mirror will slide off in an upward motion (towards the headliner)
Once the mirror is off, you can install your new mirror on the same mount. I bought a used mirror, so i had to extend the harness
Black = ground
red = power source
blue = constant 12V
To install the new mirror, first loosen then hex bolt.
once it's loosen, slide the mirror over the mount still on the windshield. Once it's mounted, retighten the bolt
Next run the wires up through the headliner over to the A-Pillar. I removed my dome light housing to be able to see more clearly where to pull the wires through.
I ran the wires under the headliner, and down the a Pillar to beneath the dash
remove the screw here under the dash to pull down the panel so you can see your wiring and fuse box easier (assuming you wire it into a fuse)
Once installed, you should have a working autodimmer mirror and homelink
