2021 Tundra limited power folding mirrors

To my knowledge, no OEM style tow mirrors come with them

 

Gonna be digging some sweet holes with that tractor to bury what you caught in the trap? The mirrors might be a little big, but safety first and it looks like you've got the start of a good party there.

 

I meant for the regular mirrors. Are the pin parts number for the mirror folding button and mirror connector correct? I tried looking for it and nothing showed for it

 

Haha. Feral cats. We have 13 of them. We catch, get em snipped, and roll onto the next. The tractor is my 3 year old's

 

@RainMan_PNW can chime in on that as he's done quite a bit of research on the wiring for mirrors but I believe so.

 

What’s the question? Busy day at work.
If you’re adding power folding mirrors to a truck that didn’t come with them, hit this post in my build thread
https://www.tundras.com/threads/caseys-2021-lunar-rock-trd-pro-build.77317/page-10#post-2163301

Modified Wiring diagrams, Pinout details, connector pictures, and part numbers are there. Power folding “normal size” mirrors are the same connector and pinouts, just that not all of them have all the options.

someone asked about memory seats in a Limited - while technically possible, it would require swapping out a shit-ton on components, running a bunch of new wires, and would probably cost you a small fortune. The seats, mirrors, and steering wheel tilt are all integrated, and the actual power components aren’t available separately so it would be major surgery.

finally - I’ve recently had one of my Boost Auto mirrors apart to trouble shoot something, and I will say two things:

1. They are built hell-for-stout inside
2. I can’t see any way to squeeze any kind of puddle light into them.

 

ok with the "normal size" mirror from 1aauto, how do i go about getting them to work with my 16 limited. is it just plug and play or do i have do some cutting and wiring? i do have BSM on my truck. also do the oem mirror cap fit on them?

 

Don1, for the most part I understand your upgrade to the power folding mirrors for the 2021 Tundra Limited.
I too have a problem not being able to park my Tundra in the garage without getting out and folding the mirrors.

To be Clear about your solution.
1) Purchase the replacement switch on Amazon --

$22 uxcell Rear View Power Mirror Switch Folding Fit for Toyota 84872-52040

https://www.amazon.com/dp/B01KU4KXDO?ref=ppx_yo2_dt_b_product_details. This is a replacement to the existing switch in the 2021 Tundra Limited to add the push button capability to fold and unfold with the push button.
2) Purchase the 2018 Toyota Tundra Driver & Passenger Side Chrome 2 Piece Mirror Set TRQ MRA04610 from 1A Auto.
2) Purchase the pins you describe above that will be needed on both the mirror side and the switch side.
3) Replace the manual mirrors with the 2018 Tundra power mirrors. During the replacement swap pins 9 and 18 on the mirror side connector.
4) On the switch side, for the mirror folding button, it is unclear how to wire the push button with pin 175265-1 indicated. Could you elaborate a little more on the switch side for the push button wiring?

Thanks.

 

Here are few pictures I took that show the wirings

 

Mirrors upgraded!
The following is an update on what was ordered and situations I encountered during the upgrade.

1) Purchased the replacement switch on Amazon, here is a link to it.

It is slightly cheaper than the solution Don1 provided and has a small harness. Harness was not used.



2) Purchase the 2018 Toyota Tundra Driver & Passenger Side Chrome 2 Piece Mirror Set TRQ MRA04610 from 1A Auto.

3) Purchased pins TE 175265-1 for mirror folding button. No problems getting them into the replacement switch.

4) Purchased pins TE 1123343-1 for mirror connector. Had problems inserting these pins into the plug.
Looks like the guide on pin is on the opposite side. Had to cut the top part guide of the pin to get it to slide into place. Probably not the exact pin for this plug but I managed to make it work.

5) Replace the manual mirrors with the 2018 Tundra power mirrors. During the replacement swap pins 9 and 18 on the mirror side connector.
Turns out it is tough removing those pins from there housing. I just cut pin 9 and 18 and re-routed them by soldering them back together. Used a shrink tube to cover the soldered wires.

Turn signals on the mirror work. Which is something that is not on the original mirrors.
I did not test the heated mirrors option, I assume they will work. We'll see this winter.
Puddle lights are on the new mirrors and were not on the original mirrors. No big deal to not have them work.

Most time consuming task was routing the wires from the replacement switch to the mirror connectors.
They have to go through the door jams. Through the wiring boot between the cab and the door.
Used a rigid fishing tool as that worked out the best.

Don't have to get out of the truck to park in the garage any more!!! That was getting old.

Thanks to Don1 for his original posting and follow up pictures as it motivated me to pursue this upgrade.

 

Glad that it works for you and thanks for sharing these steps. I also have installed several cameras(Front, left side and right side) and controlled them using the buttons on the steering wheel. If interested I can share more infor about the wiring and components I used for this upgrade.

 

Yes, please do share. I would be interested.
I currently have a camera installed on the windshield behind the rear view mirror. Not the best solution but it was a quick add on.
