Just did the mirror install following the above directions.
Sourced my mirror here (same mirror):

Ended up being a little bit cheaper, and being Prime I got it in 2 days.

Homelink works well and the lights on the buttons are not intrusive. Dimming is really fast. However, even though the mirror itself is frameless, the dimming portion has a border of about 2 mm.

I went with the Posi-Tap Taps minis. They worked perfectly for the gauge of the wire:

Does everything come from pin 2 and 9? I see how the mirror is connected. Radar detector is from another inline tap. How about the dash cam power source ? Thanks.

 

[tyrian869]

I too would like to know if we could tap into a power source for review mirror with Homelink for a dash camera, does anyone have a electrical interface documentation with voltage and amperage as it would be nice to just add an additional harness to the existing space behind my review mirror plastic housing area, I found it really nice that you can slip the dash cam cables around the plastic shroud. I that cover would hide everything if we could get power from it, Even if it was a 12-volt source, we could add a battery elimination circuit that steps it down to the proper voltage and use say a USB type-c which most – cams use these days and have a type c breakout board that we can then solder a harness end to I personally don't even use the home link feature but it may have been a great choice because I'm not sure if The versions that didn't get that option have an existing wiring harness somewhere in the roof liner, which is also another thing to to consider if running cables through the headliner all the way back to the rear camera It looks like there may be a space between from what appears to be a fiberglass sort of hard inner shell roof liner that seems like it's separated or lack for better words divided from the actual chassis. Let me know y'all's thoughts

And for those who are wondering, this is the camera system I'm installing.

 

[tyrian869]

For reference, these are the connections CorollaNewbie was referring to.

The cable you see on each side coming from each camera is outlined in red inside the plastic enclosure so not to confuse it with stock wiring.

 

[tyrian869]

Note: Parking mode with the camera I'm installing provides surveillance on your parked vehicle. When the engine is off. Hardwire Kit is used to provide continuous power and protect your car battery from being drained. They manufacture of this product recommends to buy VIOFO HK3-C ACC hardwire kit cable for parking mode recording.

Well, after a quick test of turning the vehicle off opening the door, closing the door, locking it as if everything inside the vehicle is turned off. Obviously the power outlets aren't continuous. They shut off when the car is off but it seems when I press buttons on the review mirror I get a light and where there's light. if this is constant even when the car is off then that's great, cut the harness short and tap it in possibly, So this device operates on 5 volts and no more than 2.5 amps. Yes, the device is type c but it probably is just a 2.0 version of it. Plus the 12 volt adapter states it's 5 volt on its output at no more than 2.5 amp. So if anyone knows if there's a viable supply we can tap into these are the requirements.

Additionally, I'm not so comfortable pulling the inner paneling off. I guess it's the front something pillar where the tweeters are as those have airbags labeled on them and I'm not sure if that's safe to disassemble.

The OEM Toyota "frameless homelink mirror" is battery powered, according to the GRC configurator on Toyota's website. So there isn't any car power going into the mirror? Why would Toyota do it this way...

They did it this way because it's toyota. They need their parts to fit as many vehicles as possible to keep the cost low.

Guys just install the mirror that OP described.
It works. It has Homelink. It auto-dims. It's better in every way.

The damn thing even tells you if the door is going up or down. None of my other Homelink-enabled cars ever did that.

Forgive my ignorance did you tie into the connector in your first pic or last pic?

Nope I used the wiring kit bought separately and ran it down the front left A piler so I think its called, behind the the airbag down to the fuse box using a fuse tap. I set the cutoff to 12v, for the power regulator, but in time might adjust this.

Is it different than the ones they install at port?

Guessing its different.. My car came with homelink frameless mirror(port install), and never noticed it to have auto dimming. Also I haven't had any luck getting mine to sync with my garage receiver yet...

If it has the tab at the bottom to flip it, it’s the same one the rest of us got as a port installed option. It doesn’t have auto dimming, it’s manual dimming. It is frameless and has homelink. The buttons are on the bottom left.

It does have the tab for self dimming so yup, that's it aright. Anyone have issues trying to sync it with their garage receiver? Car came with no instructions for it. Watched a lot of YouTube videos on it and they basically all say the same unless one has the rolling code garage door opener... Mines I'd guess is at least 15 years old so I don't think mine has that. I just been holding my receiver close to my mirror, holding both the door 1 on mirror and garage receiver but at same time until way after mirror is done with slow blink and is then repeat blinks rapidity. I've tried this varying timing like 25 times and no luck syncing.

 

[CharlieGsanD]

i had the issue of trying to sync a modern rolling code remote to an older garage door opener at my last place & was able to get it working by installing a rolling code receiver i picked up at home depot for about 15$.

 

[ND4SPDR]

Just installed the mirror mentioned by OP, total
Installation time was maybe 20 minutes. Easiest thing I have done on this or any car, ever.

I used the Positaps as well, those things are magical and I should have bought them for my subwoofer installation and saved myself unnecessary agony.

 

[Ozymandias]

@fradlis Thanks for the writeup, I really appreciate it.

 

[NuBieGRCorolla]

Do you have the T6’s diagram? I assume it’s a different plug….

 

[Ozymandias]

Sure, here's T6 that connects to the "map light" aka "personal light."

 

[MRT2]

I used this V1 wiring adapter to tap into self dimming mirror power connector (simple paddle push in)..

I used this mirror mount to solidly attach my V1 to the mirror..

Hope this helps!

Adding pics of how it all looks installed..

Awesome! Thanks for the write-up! I often see this thread being forwarded on various FB pages.

I'm trying to avoid using Posi-Taps and because you know the pin/plug style, can you point me out to which adaptor I should purchase here?

My assumption 10 pin type B? (I want to go this route for the ease of interchanging something. Any assistance appreciated!)
