How to: Upgrade to an auto-dimming rear view mirror 

Find a new mirror on Amazon... US: amzn.to/2ie8ReU | UK: amzn.to/2hTFe6d ...or get a used one from a wreckers.

This guy's voice lulled me to sleep and made me feel safe.

I have been looking for a guide in three different languages for many hours and your video tutorial is just awesome. Thanks a lot!

It can never be a waste of money if you enjoy doing the project

Great tutorial, good clear instructions, thanks.

Crazy how this is still an option on new cars and costs $600 when you can just buy one for $20 and connect te cables and done

Replacements for my auto dimming mirror is no less than $99 here in the USA. The Ford Dealership wants $212 for my 2011 Fusion hybrid. There is no on/off button or power light on mine. You got lucky with a power source that close!

Great little video on this subject well done.

Very helpful. Please clarify which of the courtesy light wires are the main ground, and the positive. And thought it would be helpful to have a closeup of the finished exposed wiring as viewed from under and back of the newly installed dimming mirror. Thanks again for such a lot of work to help us all.

excellent video just what a i needed

Great video

I did the same upgrade a few years ago on my Chevy Silverado since it only cost $10 on ebay -- I don't know if there's a fix, but the electrochromic mirror, as Chevy calls it, almost always displays the wrong direction on the compass feature in the mirror -- The dim feature works great. Along with the mirror, I also got the OEM fog lights I was too cheap for when it was new; they were $18. The best part of it was both options were pre-wired at the factory and a harness and plug were right where I needed them to be -- For the fog lights, I just had to cut out the spaces in the plastic molding below the bumper to mount them, then install a switch in the dash; the wiring for that was there as well. I suppose it makes sense from an assembly line perspective to pre-wire various options; makes me wonder if all manufacturers do this???

Looking for a solution to undo this "upgrade". Previous owner butchered the procedure and sprayed expanding adhesive all over the glass and then the mirror fell. I just want to see who's driving behind me. haha I'm screwed.

Hi, thanks for the video, can you provide a wiring diagram for this mirror please.

I have a 2010 Corolla with an interior dome light just like that 1 and I want to upgrade my mirror to a new one like this cause it's wearing out can I use the same type of installation as you did? I don't know anything about wiring and I really don't want to have to start to mess around with stuff like that I've been searching for the past hour on Google trying to find anyone else who had the same installation done on their 2010 corolla like mine and of course I can't find a single forum or video anyone you're the closest I can get please help? Lol

The manual for those mirrors says to NEVER spray cleaner directly on the mirror itself because it will damage it. You're supposed to spray the cleaner on the rag, then wipe.

One issue, if your car sits for a while that mirror is going to draw on your battery if you do not manually turn it off. I personally would have ran a wire down the windshield pillar to a switched power source so it does not work unless the acc or ignition is on. That way it does not require you to switch it off and on manually. A good source is your stereo. It will have power even if you switch off the vehicle and remain seated in it. Once the door is opened the radio and mirror would then switch off. That's just me personally though. Also some alarms work off the interior lights pulling a draw, the door opening. You have such a vehicle and don't turn off the mirror and a car drives by and hits your car with the headlights and guess what. You're waking up to a false alarm. This would happen a lot in a busy neighborhood

Could you conceivably connect this to a normal battery or would that not last very long? I'm about to get an 18 plate yaris which does not have this kind of mirror in it so I'd love to upgrade it but I have none of the tools you mentioned.

I want to upgrade my Infiniti Q50 but I'm not sure what type of wire I need to purchase. any input would be great!

hey mate ive just brought the same car that needs a clutch replacement. any ideas on where the cheapest place to buy one in New Zealand would be? also dothese models have the double weight flywheels? cheers

i have one on my MK3.. well looking for dim the side mirrors now heh

Hello, thanks for the informative video. I'm in the process to upgrade the mirror on my Altima. When I was to buy the auto-dimming mirror, the store asked me if my car has navigation or not. Do you know how the navigation and mirror can be related?

Isn't power to the courtesy light always available when the car is off, meaning that the rearview mirror could be drawing power all the time and potentially drain your battery? I've always assumed for dashcams and so on you need to run another cable to the fuse box on an outlet that only gets power when the ignition is on.

I have a 2016 Veloster Turbo with factory auto dimming rear view mirror, it has never worked since I purchased the car new. Do I need to subscribe to bluelink to have it work? Found out after I purchased that even though I had the Tech package which include remote start and remote climate control, they would not work without a $200/ year Bluetec subscription! Love the car but that’s just not right. Thanks for your great video and would appreciate any info you may have on mirror. Thanks, CW Midlothian, Va

Hello, I watched your RU-vid video on how to DIY upgrade to auto dimming rear view mirror. I successfully installed it on my Toyota Corolla LE 2016 model but it's stays on on default. Even when i turn off the engine it stays on. If i turn it off manually, i have to always turn it on manually each time. Please what can i do?

There are 3 wires in the mirror, did you connect the reverse light wire to undimm it?

"The amazing convenience"

good morning, where are the 3 wires connected on the mirror and in the ceiling light? from the video it seems that 2 wires start from the same contact on the mirror. thank you

From which car was this Auto dimming mirror removed? I've got a similar one already retrofitted in my second hand Toyota hilux, and unfortunately, it failed. So I wish to replace it but I don't know which vehicle's auto dimming mirror to find.

There are 3 wieres . From left to rigt.. Positive(+) Negative (_ black) and the third one is for what ?? Thanks !

How to replace my existing rear view mirror on my 2018 Hyundai sonata for a home link rear view mirror

Well problem with connecting it directly to the courtesy light (KL30) is that dimming will always be running and that brings a risk of drained battery. Atm I'm trying to figure out a way to connect mine to ACC line (KL15) so that when the vehicle is completely off it wont draw any current.

I’m thinking of doing this, but am not very savvy with electronics. Anyone who can tell me which wire does what. I get that the black wire is the ground, but the other two wires I don’t get... are they both supposed to be powered, or is one not necessary? Great video nonetheless!

That's not a mirror from mk3 Mondeo, right? Cause my auto-dimming mirror looks a bit different. Which is factory of course.

I wanna put a Auto Dimming mirror in my 03 Pilot

Had. One and loved it but new one dosent :(

Looks like a gm rearview mirror out of a silverado

Maybe because of the weather in England? In America every car I've bought since 1992 has had an auto-dimming (electrochromatic) mirror.

Play in 1.5 speed

The problem with your connection is that the mirror will continuously draw power even if you remove the key and lock the car because the dome light will work even if you lock the car. 2 weeks or month of not using the car will drain the battery completely.
