These are highly necessary to know for any remote start / security alarm set-up, hope it can be of use in the future.

On your 08, you can grab it at the TPWS ECU, behind the lower passenger glove box:

I recall someone having had an issue with tapping the purple/violet wire for some other electrical project. perhaps he was just unlucky or did something wrong.

Let us know so that this thread stays accurate.

another useful tidbit for those wishing to wire in LED mirror covers, you can get the signals from each side here. This is for the big relay/junction box in the driver's footwell area.
This way you don't have to go into your engine bay to wire them up :smile:

I'm looking to add a few lights under the dashboard that are on the same circuit as the dome light (so they turn on when the door opens) and was wondering which wires they are. I have the 09 sedan, does anyone know which wires I could use?

http://www.yarisworld.com/forums/attachment.php?attachmentid=27159&d=1250041800

The connector (4K) on the upper left in this picture, is the feed to the map and dome lights. White with a black stripe ground, Pink is the "door open" switched ground, and blue is 12V fed from the DOME fuse.

Use the clip things (tap splices). Just sticking the wire in along side of the existing wire does not make a reliable connection.

There was a website you could get all of this information from. Most diagrams were on the12volt.com in their forums I think.

Somewhere on there I believe someone posted the login information to get on to one of the installer websites to get access to all wiring diagrams.

I went there to get everything I needed when I put in an alarm/remote starter for my Impala back in the day.

Haven't needed to go back though. Cheers to AllData! :thumbup:

Pop the trim from around the speedometer and you'll see two connectors going to the cluster assembly. If your car is left hand drive the connector you want will be on right and if it's right hand drive it will be on the left.

The ScanGauge gets it via CAN Bus data at the OBD port. If your car has TPMS the speed signal is available there as well. honestly, popping the trim from around the cluster takes no tools and just a couple of seconds.

Pull off the two vertical black pieces that surround the radio.

Pull the cluster trim gently at the top, where the seam is to loosen it.

Pull the cluster trim along the bottom straight back towards you to free the tabs that go into the top of the radio trim.

yes is their nitrous brand, and yes it come with a sensor but i dont want to drill a hole on my car for the sensor, but if i can get around it and NOT drill a hole on my car will be better

now for the sensor it only have one cable and you give me two, so i didnt know on wich one to plug it in so i havent test it on any of them yet

now i gues that you r familiar with the gauge that i got, is there a extra hole on the car that i can put the sensor that came with it???

That makes more sense. The more I thought about it, I realized that water temp gauges aren't like tachs, where you can tie them to a standardized signal.

As for where to add your gauges sensor, there really isn't an existing extra hole that I am aware of. I believe that there are plates that can be installed under the thermostat housing that give you a place to install the sensor. I've seen people install them in other cars by drilling and tapping.

I know that others on here have installed them, So, you might want to start a new thread asking where and how people installed their sensors.

now let me ask you a question, do you think that if i use one of the line that you told me from the pin 96 (pink) or pin 97 (blue) i think i could try that and see, because i reeeeeeally don't want to drill a hole on my car, and now that i think there must be a line that i can tap into because, on the speedometer there is two light for temp, one light up COOL so when you start the car and the other is the red light that have the signal of hot temp, anyway let me know what you think

I don't believe that it would work. The single wire sensor is a one wire thermocouple. A two wire device, like what is on the car, is a thermistor. A thermocouple generates voltage relative to change in temperature. A thermistor changes resistance based on temperature. So, the output of the two sensor types is completely different.

As for the lights, they are illuminated by the cluster's microcontroller, based on data from the ECM (who processes the sensor data).

I want to wire up some aftermarket LED driving lights. I want them to come when the car is in drive. Is there a easy place to connect them? 2010 5 dr HB. Thanks.

To have them come on when the car is "In drive" with an automatic transmission, you could tap the connector C27 on the transmission. The 10A Gauge circuit feeds through the Park/Neutral/Position Switch on the A/T to feed the indicator on the cluster and the ECM with the position of the A/T shift. For low power lights (LED lights under 1A) you could feed them directly. For high power lights (incandescents or HIDs) you would have the Drive indicator feed the coil of a relay, which would then have it's own power feed for the lights.

C27 is the 9 pin connector on the front of the transmission (by the shift linkage). It has a row of 4 and a row of 5 pins. The center wire (light blue) on the 5 pin row is the "Drive" indicator wire. It will have 12V on it when the shift is in drive. For ground, you can grab a chassis ground, like the ground bolt under the left headlight.

You can tap into the turn signal wires in the under hood fuse panel. On connector B13 (left connector in this picture), the light green and dark green wires in the upper row (next to the two red wires for my fog lights) are the turn signals. Light green is left, dark green is right.

If you tap the pink and blue, the LEDs will behave the same as them dome lights, provided that you leave the dome light switch in the "Door" position. If you manually switch the dome to "On", with the doors closed, the LEDs won't light up with the dome.

The black one is for the Door lock receiver. Does your Yaris have a manual or automatic transmission. If it's a manual, then the other two are for the A/T shift illumination and for the shift lock control ECU.

OK. First off there are two blue wires on the headlight stalk. The "light blue" is the darker of the two. The other color is called "sky blue".

Secondly, you don't want to use a high current circuit, like the headlight switch, to drive interior lighting. You want to use the illumination circuit, which you can access either at the shift lever or at the dimmer rheostat.

At the shift lever, there is a two pin connector with a white and a green wire. Green is +12, white is ground.

At the dimmer rheostat, there is a 10 pin connector. The sky blue wire is +12 and the light green is the headlight switched ground.

So i tried the sky-blue wire at the dimmer and it works. However its dimming the power window switches in the opposite direction as the dash. So when the dash is fully lit, the power window switches are not lit at all and vice-versa.

I checked the connection with my multi-meter and it is indeed +12V so im not sure whats wrong.

My car is MT so there is no shift lever, is there another headlight source i can tap?

Thanks for the help!

That's correct. Is the light wiring on your switch separate from the switch controls, or is it integrated, where it shares the same ground? It sounds like the latter, as the dimmer brings the ground up, rather than the +12 down to do the dimming. If that's the case, using green as your + and chassis ground as your ground should correct the reversed behavior.

nmd55

10-26-2010, 11:25 PM

as it turns out i was tapping the LG wire the whole time thats why it was dimming in the opposite direction. However the SB wire is an ignition switched 12V, so tapping that doesnt work either because the switches are on all the time with the SB wire.

I think i am going to have to find another source to tap.

The only way to make them function exactly the same as the dome, including the switched on mode is to run the power wire up through the headliner to the dome light and make your connection there.

Thanks! I just tapped power for my 12V footwell LEDs from the 4K connector, pink/blue wires. However, I used some old wires from my old computer (more or less same thickness/gauge as the pink/blue ones, quite thin). I think they're around 22-26AWG, same as the original pink/blue wires, however the pink/blue wires may be solid copper core, while the wires I'm using are stranded aluminum.

Now I'm worried they might catch fire/melt/burn. What's your opinion on this? Should I get thicker gauge wires and redo the whole thing?

That feed is fused by the DOME fuse. As long as your wires are sized appropriately for that FUSE you will be fine.

This is what i'm trying to figure out, Scott. Cos the wires i used were pretty thin, 26AWG. I dont know the gauge of the original pink/blue wires coming out of the 4K connector to the dome light,
but they look pretty much the same.

Those wires are actually 20AWG. Your 26AWG is only rated for 2.2 Amps, so to be safe you should add a 2A inline fuse between it and your new lighting.

The red one that's hidden on the end of the second row is definitely ignition switched +12 volts. Make sure you have a good ground that you are referencing it to, or use the white wire with the black stripe on that connector as your ground.

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.

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.

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.

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.

thank you so much scott for replying..

i've attached the wiring diagram i received from the maker.

the information i received for the"oil circuit detection"wiring has got to do with the fuel pump wiring.it is added as a security feature in anycase if somebody try to breakin in the car without authenticating the wirelesskey(force breakin).The engine wont start.it has something to do with shutting the car off.

i think that in this case is not oil but fuel.

CTScott

10-19-2012, 01:19 PM

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.

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.

If nobody answers, you could get a test light and turn the key to accesories. With the hand brake up, you could just put it in reverse. Use a test light and back probe each wire. Record which ones have power. Then put it back into park and check again to see which one no longer has voltage. I can't look up the wire diagram right now while i am at work. CTScott would be the one to get the info to you the fastest.

I think I'm going to pick up a voltage detector from Lowes tonight. One more question: will I be able to tell which wire coming from the reverse light is positive (versus negative) simply using an analog voltage detector?

I removed the center console panel to check the cigarette socket wirings.

Yes, you can "share" power outlet for that dual USB. I took power from the front one on my Yaris.

People who can share wire schematic/diagram for master windows switch. Look to hookup original master switch to aftermarket power window kit want use original switch instead of one from kit to have auto option.

can you please tell me where to take off a 12 volt feed (when the high beam is activated) for my driving lights relay.
Little or no voltage or current required, just power ONLY when high beam is activated.

Thanking you in advance.

The headlights are earthed to turn on, with permanent 12v power. The simple way is to wire the relay coil across the 2 parallel contacts on the headlight socket.

Hello everyone.
I Have ghe Toyota Yaris Sedan 2007

I am trying to install a wireless back up camera. i found the wires at the back but know i am searching the reverse wire at the panel.

To explain how it works. we have the transmitter and the receiver. Transmitter is at the back and it connects with the reverse light witch i found the wires.

The receiver connects with the Head unit and i have 2 more wires red and black .

Hi Everyone , i need some help.
I was able to Install a Headunit in my Yaris 2011 - i think i screwed over some wiring connections , so here is what happens now

1 - I insert the key in and move to Accessory level of the key and Headunit powers up - NO AUDIO

2 - No Audio shows even when i move the key to Start position
3 - When i move the Key a little bit beyond the Start position where engine starts to make a bit of funny sound , the Speakers start sounding
4 - Funny thing is all this time Stereo is ON and i can access its screen and buttons so power is coming through
5 -Lastly when i switch off the car and move the Key back to Lock Position , Radio starts to sound and Speak wakes up , ONLY for a while and then Car is off

I must have messed up the Wiring , but i dont know what i did wrong , Please help -
Can you please elaborate what each of these Color wires in my attachment does and which part of it is where its possible gone wrong ?
