2019 TRD OR; ordered the part off ebay here: 89121-50020 Automatic Light Control Sensor For Toyota Camry Tundra Sienna Lexus | eBay

Installed using electrical tape, confirmed it worked (during the day) by turning headlights on, placing my hand over the sensor and watching it switch into night mode, then removing my hand and watching it switch into day mode.

In lieu of a credit card a hook/pick makes removal of the dummy sensor a breeze.

NEVER heard of this but that is awesome.

I ordered the ambient light sensor part number 89121-50020 for my 2021 ORP and it did not match the harness. Anyone else with this problem? Thx

 

[trdgmn]

I found the answer. Harness changed for 2020+

Whoops, guess I should've gone through the thread a little more thoroughly.

I took my 2021 TRD Offroad in for service last Friday and asked how much the sensor would be for this and they stated $196 and they would have to pull the dash, order some special tool, install a harness, and potentially replace the head unit to get this to work. I told them I already have the harness from the factory, but wasn't going to pay $196 for a simple sensor. Found one on ebay for $36 this past weekend, got it today and it works perfectly. Part number 89121-30020

Anybody found the sensor for a decent price for a 2022? I believe it's the 89121-30020

Yes, that’s the correct part. I got one on eBay for $50ish. Shipped from Japan. Took a while to get here. Installed in 5 minutes. Works perfectly. Love it.

I just found this thread and have a new 2022 (RIP my 07 V8). Does this make the headlights (low beams) automatic? and if so what position do you leave the stalk in for it to work?

No. It just dims your screens and dash

Thank you. Hopefully I can find one soon for a decent price

If it helps,
It’s the same sensor used on 2020, 2021 Camry. I found one for a 2020 4Runner - easier to search the part for Camry.
And the newer ones are expensive I thought.
I replaced the dummy light sensor on my 2020 Venture and with the headlights on, the dash and infotainment lights dim when the driving and or headlights are on.
Easy project. ������

Just curious about seeing part 89121-30020 at Discount Toyota places for about $135 and then on eBay for about $65. Something seems amiss, are the eBay ones China imitations??:wtf:

Still seems a bit strange but I have gone ahead and done the same, ordered from Japan, $65 total.

The $5 mod has turned into $85, so strange. Opted for the $17 chinese version. It works and installed it. Got so tired of being blinded every morning starting the truck. This is like a no brainer and should have been included for the purchase price of the 4R.

 

[Cadesun]

Do you have a link to the Chinese version? I had this in my '15 and am really missing it in my '20.

I don’t think the Chinese (cheap) version will work on your 2020!

 

[IslandJim]

It was a chinese fail anyways. It worked during the day when I tested it, the dashboard lights did not dim when I turned the lights on....Early this morning turned the key on and my dashboard is blinding me as usual, turned on the park lights then the dashboard dimmed. (shakes head). Well its not coming out, just going to have to keep turning the parks on I guess.
