Wires Inside the Yaris & What They Do

On the headlight stalk connector (remove the bottom steering column cover to get to it), Pin #13 is the switched wire for the taillights (which turns on with with both the high and low beams).

If the car has daytime running lights (or is 2009 or newer), then pin 13 is a ground, switched by the headlight switch (so, you would use pin 13 as your LED ground and would connect the +12 wire for the LEDs to a 12 volt source).

If the car is 2008 or older and does not have DRLs, then Pin #13 is not a switched ground, but instead is a +12V feed which is switched at Pin 10 (the wire to the left of the Pink one) (which will be green instead of white with a black strip). So, on this vintage, you would connect the + wire for the LEDs to the green wire in pin 10 and the - wire of the LEDs to a chassis ground.

I really messed up, but I would like to know if anyone has had this issue or knows a solution or what's going on.

YIKES!!!!

Check the Dome and ETCS fuses in the under hood fuse panel. Hopefully you popped one of those and didn't cook the ECM. The DLC3 connector is purely for diagnostics. There is a constant power wire on the connector for powering a diagnostic tool, but other than that no pin on that connector should ever be connected to a load.

where is the reverse light wire?
and what is the colour?

Hi,

Trying to wire an aftermarket radio
Please advise:
Re- yellow wire, a black wire, a pink wire and a white wire - which wire is ground (earth) and which wire is power - 12v? Which fuse is the radio fuse? The radio works if I connect directly to the battery...

What year is your Yaris and was it built in Japan or France?

Can any one help the abt the chip on the pic coloured red and blue. what is there function?Be cause one of them getting hot. What actually they do? and also the function of the fuse? How do i know whether they functioning or not.

They are relays. The left one is the IG1 relay and the right one is the HTR relay. The left one gets warm when the ignition is on and the right gets warm when the blower is running. That is normal.

The fuse above it to the left is for the power windows and the one above it to the right is for the defogger.

Where is this whole piece as seen in post 14?
I want to wire some door sills and have them light up when the door opens up. I usually keep the light in the off position and not on the "door" position. So if I want it to work the way I want it to, am I going to have to keep the switch on "door"? This might be the wrong thread but I was redirected by Scott on another thread. Thanks!

Behind the little storage cup on the bottom left side of the dash.

Oh ok! Thanks.
And where can I tap into the parking lights? The lights that turn on when you twist the switch half way. I am also installing some LEDs for the interior and I want them to turn on w/ the parking lights. And do any of you recommend the "L bars" or just regular LED clusters? I want them to go under the whole dash kind of where your feet go.

I thought your post might have been spam with odd combination you were asking about, but since you sent me a PM with some specific questions, it seems like you are not a spammer.

In your PM you mentioned that you found all except these two:

1.Oil circuit detection
2.Cut oil and electric circuit off.

For #1, the Yaris has an oil pressure switch that is located on the front of the block about 6 inches above the oil filter. It has a single yellow wire (since its case is grounded to the block). That yellow wire is only an input to the instrument cluster for the warning light.

For #2, I am not sure what you are looking for. The only circuit associated with oil is that simple oil pressure switch.

[CTScott]

OK - That makes more sense for it to be the fuel cut-off. Sometimes the directions seriously lose something in translation.

In that case, you are interested in the violet wire on Pin 7 of the smaller ECM connector.

[CTScott]

I would need to see a better explanation of the module. In theory there should be two wires - in and out, so the device can interrupt the fuel pump feed.

hi! If I want to turn something on with the flash or high beams od the headlight, were I had to connect the + and - wires of my 12v circuit? I wanna do this because I want to open my garage goor with the opener activated when I flash my headlights.

Maybe I have to tap de + with the Pin 9 and the - at the Pin 11?

If you have a 2005, then yours is a fist gen, so the headlight wiring will be different than the second gen connector pictured.

For the first gen, the red wire with the yellow strip in pin 9 is the high beam wire from the switch. That wire gets switched to ground when the high beams are flashed, so you would use pin 9 as your switched ground wire.

You would want to use a relay that you switch the coil of with that wire, and then use the normally open relay contacts to trigger your garage door opener's switch.

regarding to colors, I cannot rely
lol

Mines is a european base model so maybe for that the colors difference

Ok I get it about the pin 9. So I tap here the - right? what about the + connection? Also the relay for what would serve?

sorry for the question but I know almost nothing about this

please send full detail on toyota yaris sedan year 2008. .front totally damaged in accident .if someone selling parts let me know..! wiring system completely damaged.
