My $5 mod in 5 mins.

[kaitlyn2004]

It SEEMS my gauges and console controls do NOT adjust the lighting automatically. These are the photos I took of the front sensor spot thingy

How do I know if that's the sensor/working or not? I have the Canadian 2020 TRD Off-Road

I do have auto high beams...

Park in a dark place, grab a flashlight, and go back to post 55 of this thread. The sensor operation is described there. At least for how it works on my 2018 ORP. Your 2020 may be different.

What is all thats needed if you don't have a harness ???

I mean I can get a harness and what's it connected too or is this a waste of time for the amount of money that I would need to do for a small mod

I have a 18 SR5 Premium. I see majority posting it isn't working for the SR5's. Has anyone pulled the dummy plug and tested the wires with a multi meter to see if it's receiving any current? I figured it would be better to test to see if I do have the wires that they are plugged in on the other end before ordering the new plug.
Thanks

Make sure the dimmer dial to the left of the steering wheel is not locked in the full up position

Anyone have luck on a 2012 Trail Edition?

I took this cap off a long time ago to run wires for my vhf radio but after seeing this I might need to rip apart the console to see if I had wires attached, I don't think I did but can't remember. Would be surprised.

Yeah it's not. How do I know if it's the sensor or just plastic cap?

This worked on my SR5 but I had to run 3 wires from the sensor harness to the body ECU. I never tested the existing 3 wires at the sensor, but I'm pretty sure they were not connected all the way through to anything.

This 100%.

For those with SR5's who don't get any change with the sensor, you are missing a blue, pink and red wire from the Main body MPX ECU to the large junction connector behind the instrument cluster. If you have the blue connector attached to the blank where the sensor goes, the wiring from the sensor to large junction connector is present. You just need to complete the three circuits. [MENTION=54749]LakeRunr[/MENTION] posted a solution in this thread I'm pretty sure.

Sorry, I didnt follow that you hadn't purchased the sensor. If you pry the plastic cap off and disconnect the harness, it'll be obvious that it's either a sensor with pins or just a plastic holder. But beyond that, they look pretty much identical from above. But it seems like a safe bet that you don't have the sensor anyway.

Btw, auto high beams has nothing to do with the sensor. I had AHB but no sensor.

Btw #2, the $5 sensor will not work on yours, you need the OEM one, either used or new

So I've since learned - Toyota changed it for some.. unknown reason?

I don't know anything about the part itself - is it just a matter of time before a cheap updated sensor comes out or is it not that simple?

I can answer that with a definitive "maybe"? All I can really say is that even for the $70ish used, it was worth it to me

Any followup to this?

I just installed the light sensor in my 2020 TRD ORP and so far so good.

I did have a question:

The old sensor had only two wires and the new one has four. Is there any chance it has four to potentially control the auto on/off headlight function?

Here is the link to the one I purchased.

Thanks for this thread! I recently did this in my ‘16 Trail Premium. Install was fast and it works great!

2014 Base SR5 does not have wires connected to the dummy plug.

Since this didn't work out for me...

Come hit me up at Saturday at the 7Leaves Cars and Coffee meet at 7225 Edinger Ave. Huntington Beach, CA
... I'll give this to anyone who wants it.

 

[kaitlyn2004]

Anyone have any tips for removing it from the dash? I've got plastic pry tools but it just doesn't want to pop up!

Anyone find a cheaper sensor for the 2020 yet?

Really thin metal pry tool, and/or credit cards from both sides.
