Auto dim light sensor

For those that added the auto dim (ambient) light sensor to your 2024 4Runner, which part number is it? I found 2 different ones and price difference is significant.

Part 89121-30020 or 89121-0E060?

 

I ordered mine from Amazon (gotta love that site): https://www.amazon.com/dp/B0B73ZPNFH?ref=ppx_yo2ov_dt_b_fed_asin_title




It appears that there are multiple part numbers. Both of the ones you listed are shown in the Amazon ad. Mine worked without any issues!

 

That’s the one I got too.

 

This one works perfectly.

No way I would use a Chinese part in my made in Japan 4Runner.

 

I got the aftermarket one, it didn't work. I went and got an oem one,worked just fine.

 

What a naive comment. Do you think every single OEM part in your 4Runner came from Japan?

 

Haha, I was about to make a similar criticism. But I did some brief research. About 98% percent of the 4Runner’s parts are made in Japan.

If quality is the concern, it's a basic photoelectric sensor, if it's a concern with China as an entity, I get it, I'm wondering if dealer parts are from the same supply chain as manufacturing.

 

When a manufacturer installs “made in Japan” tires on a vehicle, it’s often a point of pride, emphasizing quality and origin. By contrast, it’s rare to find “made in Germany” parts on even high-end German cars like Mercedes-Benz or BMW, and Porsche now operates a factory in Slovakia. For example, Mercedes-Benz uses Continental tires on many of its models, but those tires are sourced from all over the world. So, when it comes to maintaining the quality of my 4Runner, if I can choose a Japanese-made sensor over a Chinese one, I absolutely will. The price difference is negligible in this case.

 

It may have been "made" in Japan, but it was probably "manufactured" elsewhere. A lot of stuff is manufactured in China. They have a lot of minerals and elements that other parts of the globe simply do not have. I think almost all computer chips come from there (the material that is).

"Made" is a general term that can mean something was fashioned, built, or finished, while "manufactured" refers to the process of creating a tangible product from raw materials.

 

I understand the concept. Louis Vuitton shoes carry a “Made in Italy” marking, though 90% of the process takes place in a factory in Romania. The soles are sewn or glued on in Italy as the final step, which qualifies them to label the shoes as “Made in Italy.”
My point is that if I have the choice between a Made in Japan product vs Made in China, I’ll go with the Japanese one.

 

I got this one about a year ago after the eBay seller was recommended here. Received it within a week. Easy installation, zero problems. And to your original question, 89121-30020

I’m not sure I get you @Noodles. First you say that you’ll pay more for the MADE IN JAPAN part. The casual reader would interpret this as you thinking that parts made in a Japan are better. Then in two separate successive posts you acknowledge that components for any manufactured item can come from anywhere, and that the MADE IN label doesn’t mean anything. And then you wrap up by saying you’ll go with the Japanese one. Confusing.

 

I was referring to a luxury brand using the “Made in Italy” label, which is permissible under EU law as it allows companies to label products based on the country where the largest portion of the production process takes place. In the case of footwear, the production of the sole often constitutes the largest part of the manufacturing process, thereby qualifying the product for the “Made in Italy” label. Outside the EU, such labeling is typically more restrictive. For instance, Japanese companies are unlikely to label a product as “Made in Japan” if 40% of its production took place in China—a practice rooted not only in historical considerations but also in the Japanese ethos of work ethic and honor, as I have observed from experience.
And yes, parts Made in Japan are better. Are you driving a 4Runner or a BYD/Hongqi LS7?

 

There's two automatic light sensors - a four pin and a six pin that work in different models of 4Runners, and not all models work with even the correct sensor. Best to look at your wiring harness before ordering. I installed genuine Toyota sensors in my 2023 ORP ($40) and my daughter's 2015 TP ($80) and both work as expected. Look here for more detailed information:

 

OP, you probably want the four-pin. 89121-30020 fit for me but mine's a '21.

Worst case, test it first and do not snap the sensor in all-the-way as it can't easily be removed like the dummy part.

And if you want to be able to pull it later, you'll want to file down or modify the arm parts so they don't grab like they would.

 

This reminds me of growing up, when my mom would yell at me "You shut your mouth when you're talking to me!"

Talk about mixed emotions! LOL

 

Here we go about China made stuff again.

Everything in your everyday life has something from China in it. Unfortunate world we live in now days with so much reliance on one country.

 

The 89121-30020 worked in my 2023 ORP and I cut most of the legs off of both my and my daughter's 89121-50020 sensor for the 2015 TP in case they ever need to be removed. And when you pull the dummy sensor out be sure and secure the short wiring harness because if it falls back into the dash you'll never see it again unless you take the dash apart
