Headlight sensor install

[monkeycoke12]

I ordered one of these the other day.

It's one of those auto turn on your headlights when it gets dark sensors. It also will leave your headlights on for 30 seconds after you've turn off your engine. There is a remote line too so you can trigger the headlights remotely if you'd like.


It's suppose to be an easy install and turns out its not that hard.

The instructions are in Chinese and "English".

The install is really quite simple.
Blue wires are for the headlights
Green wires are for the daytime run lights
Yellow is for ACC power
Red line is for constant power
Black is ground
Brown is for a remote line
White is for HIDs

Well I don't have stock HIDs and I'm not going to use the remote line.

I opened the steering column by removing the 3 screws holding it in place. This exposed the harness that has the switched lines for the headlights.

You can see where I tapped into the necessary lines to turn on the headlights. I Looked all over the internet to find a diagram of this harness but alas I ended up pulling out my voltage meter and tested the terminals inside this harness to see which ones when hot when I turned on the headlights. Not to hard it went quick.

Once I was all punched in I ran the sensor to the dash, stuck it in place and fired up the car.

Everything worked great.

If anyone wants more detailed photos or better instructions let me know. I'd be happy to share.

Ok after an evening of it install I've noticed 2 things:
1: The dash indicator doesn't turn on when the sensor turned on the lights (anyone know how to get that to work? I'm guessing I just need to bridge the switch to another wire)
2: The "headlights are still on" alarm sounds for the 30 seconds that the sensor keeps the lights on. (not a big deal)

[CTScott]

The blue wire on the left side, next to the tapped white, needs to be grounded to turn on the headlight indicator.

[monkeycoke12]

Do I ground it or bridge it to the switch wire from the kit?

Ground it when the headlights are on. You should use a relay to keep it isolated from the headlight switching, since the indicator is powered by the ECU-B circuit and the headlights are powered by the H-LP circuits.

Perfect! Did the trick! Thanks!

Could anyone advise which wires (colour) of the headlights switch connector can be tapped for signal:

1. low beam
2. High beam
3. Ground
4. ACC

Same problem, unable to find any diagram from the internet for my Totoya Vios (06 model).

[CTScott]

Red/Yellow - High Beam
Red/Light Blue - Low Beam
White/Black - Ground

ACC - Not on the headlight connector, but on the ignition switch connector - White/Light Blue

[biotope]

Thanks CTScoot, I will try it out.

Btw, I thought I saw 2 x White/Blue wires on the ignition switch connector (extreme left and right) ? Need to open the steering column to confirm again.

OK - I see that. Pin #1 is the constant power feed (and is also white/blue). You want the wire in pin #3, which is ACC. The connector has six pins, so 1 and 3 are on opposite sides, like you said. ACC (pin3) is the one that has a black/red wire beneath it (pin 6).

BTW, does anyone know after I install HID, the highbeam indicator on the dash is gone, is it possible to get it back?

Do a little searching. There is a thread where I documented how and where to connect to the indicator light on the cluster to make the indicator work.

[biotope]

Red/Yellow - High Beam
Red/Light Blue - Low Beam
White/Black - Ground

ACC - Not on the headlight connector, but on the ignition switch connector - White/Light Blue

Measured the voltage between high beam / low beam signals and ground, both are at 12v even the headlights switch is in off position. Is this correct? My thought is they will only at 12v when I turn on the headlights?

That is correct. The ground, not the +voltage, is switched. There is one common wire to both the high and low beam that is always powered and then they each have another separate leg that gets grounded to turn that beam on.

I see...:eek:

Possible to help me to confirm on the wiring of the autolight sensor that I brought?

1. Red - to connect to ACC (White/Light Blue)

2. Green - to connect to headlight low beam (Red/Light Blue)

3. Blue - to connect to ??

4. Ground 1 and Ground 2 - to Ground (White/Black)

I spent half an hour and searched 30 or so threads, only so far found the one with the resistor mod, and the other one claiming there is a thread made by you, the work is done with the cluster and is simple as just a wire. But I cannot find that thread you made?

Also I searched the DIY compliation section and did a search on your ID for threads you created, couldn't find anything about HID high beam tutorial.

Do you possibly know the title of it I can search further?

Thanks:smile:

[suckerface]

Slightly off topic, but great find, thanks for posting!

That is a tricky diagram to follow unless you can read the language. The green and blue do seem to be the low beam (green) and high beam (blue) connections.


So:

Green to Red/light blue

Blue to Red/yellow

[caineroad]

fack, lol i read that thread but somehow i stopped reading after #5!!

thanks!

EDIT: Will the high beam indicator still work if i decide to get rid of HID and put back the stock halogens bulb later?

The chinese text mentioned means:

1. Green is to connect to left and right headlights (never mention whether is low or high beam)

2. Blue is to connect to the license plate light, left and right side light (not sure which lights they referring to) and display light. Question - is there any wire to tap for these lights signal?

Since it is for automatic on of the lights, I would say that green then goes to low beams.

For the blue, that would go to the green wire on the bottom right of your picture. Those lights are switched on the positive side, rather than negative like the headlights.

So, you will have to add a relay where the blue wire switches the ground side of the coil (and the positive side of the coil is connected to your ACC power wire). Then the normally open contacts will connect to the green wire on the headlight switch connector and to the green/white wire, which is the second to last wire on the opposite side of the bottom of the connector.

What is the function of green/white wire? Do you have the entire headlight switch connector layout?

[CTScott]

The green/white feeds the tail lights, license plate light, and front corner lights that come on when you turn the headlight switch to the first click (often called parking lights here in the US).

Attached are the illumination and headlight EWDs.

Thanks, have a better visualization on how the switching system works.

Tried to draw up something for the relay connection, is my understanding correct?

Correct

[Qmobile]

sweet mod! never worry bout turnin on ur lights again

[biotope]

Correct

Finally managed to spare time trying out the installation. Some issue encountered, not sure if you could advice?

Without the relay connection for the parking lights, everything works well. It could auto on the headlight in the dark and off the headlight in the bright.

But when I made the relay connection, it will auto on the headlight & parking lights in the dark but fails to off the headlight & parking in the bright. I could hear the relay switching sound but the headlight & parking lights remain on.

Tried to change another relay, still having the same issue. Any idea what goes wrong? :iono:

Still cannot figure out why the parking lights cannot turn on by the autolight sensor. Maybe the output from autolight sensor for the parking lights portion is faulty.

Thinking of making some changes to the circuit by using the autolight sensor for the headlight portion. Below is the layout, not sure if this connection feasible? Any views?

[CTScott]

That should be fine.

[yours_falsely]

Do the headlights automatically come on when the stalk is in the off position? If so, can you still manually activate your headlights using the stalk?

Yes, the headlights will turn on automatically even when the stalk is in the off position. You could also turn your headlights on using the stalk as well.

For the sensor that i have installed, it comes with an on/off switch for me to disable the sensor as and when required.

Thank you very much for the How to ...
I know that is not the Camry 1998 forum. But have the YCL light sensor 301. I have installed HID lights in my 1998 Toyota Camry. I have tried many times to make the automatic light sensor work but I have never succeeded.

My main problem is a brown wire. This "Brown" wire allegedly go to be connected to a "Mid Control Lock Down End" trigger anodic electricity.

You have some solution, images or schematic for this situation. I'll be very grateful.

Thank you very much for your help.
