1. Purchase a Gentex or Mito electrochromatic mirror.
- Don't get one with a temp sensor because we already have that and it's extra install work for the sensor
- Make sure the wire harness is included if you buy used. Also if it comes with the wire cover ask for the long one (not the short one)
2. Remove the overhead console by pulling on the sides first, then the rear and finally the front. The clips are on the sides and rear but not the front. To help understand how it's held review the attached pictures.

3. Unplug the power connector at the rear of the console. I had difficulty unplugging the 2nd plug for the mic and didn't want to break it so I left it attached. Instead I zipped tied the console onto some of the roof framework since I couldn't completely remove it and let it hang so that the weight of the console wouldn't pull on the mic wires.
4. Locate the needed wires on the console power plug. See pictures below for better understanding. The wires are coded as follows: Constant 12V is yellow with a light purple stripe and Ground is black with a white stripe. I could not find a good ignition 12V source in the console plug. The one that exits in this plug is 8.5V when the ignition is on and decreases to 4.5V when the headlights are turned on which isn't sufficient to trigger the mirror properly. For the 12V ignition you'll need to tap a 12 volt ignition controlled fuse at the fuse panel.

5. I used the included wire taps to attached the mirror harness wires to my existing overhead console plug

6. Run the wires above the roof liner and out the slot that already exists in the front of the headliner to the mirror
7. For you ignition 12V source you'll need to buy an "Add a Fuse mini plug" from your local auto parts store (Google the term to see what it looks like). Run a twisted copper auto grade 18 to 20 gauge wire from the overhead console area along the top of the headliner to the A pillar on the passenger side. You'll need to remove the plastic cover on the A pillar (it's held in by three blue push pins) by pulling on it outwards starting towards the top. Be aware that the top blue push pin is attached to the plastic A pillar cover that you're removing. You'll need to detach it before you can completely remove the A pillar cover (it just slides off). Run your wire down the passenger A pillar and zip tie it onto the existing wires along this path. Ensure not to interfere with or run the wire in front of the airbag in this location.
8. At the dash you'll need to fish the wire from the top of the dash (at the base of the passenger A pillar) down through the dash to below the dash where the interior fuse panel is (above the foot area on the passenger side). To remove the soft cover above the passenger foot area (which covers the fuse panel) you'll need to pull off two black plastic plugs. They come off by squeezing them and pulling downwards. Then gently pull down the soft cover which hides the fuse panel. I had good luck using a stiffer lower guage wire to fish through this area from the bottom up. After fishing the stiffer wire up through the dash I attached my new wire to it and pulled the wire down through the dash.
9. Next pull the 7.5 amp mini fuse in the 85 position. It's a 7.5 amp fuse which is ignition controlled and is labeled in the manual as "Electronic 15 feed".
10. Attach the wire you fed down through the dash to the "Add a fuse" you purchased. Place the 7.5 amp you removed from the vehicle into slot A on the "Add a fuse" and a new 5 amp fuse in slot B. Put the "Add a fuse" into slot 85 where you removed the 7.5 amp fuse from. On the overhead console side attach your ignition 12V wire to the red wire on your new mirror plug which should be labeled ignition 12V. Your wiring is now all set.
11. Remove your existing mirror using a flat head screwdriver to reach underneath from the bottom. Used a thin flathead and gently push up away from the glass as you pull up on the mirror. This guy on the Focus website explains it well:

12. Slide the new mirror onto the windshield wedge and tighten it. Mine required a T20 torx screw driver.
13. Attached the plug to the rear of the mirror and test. If all works well program the Homelink feature per the included instructions that came with your mirror
