The Asian market Yaris do not have the dimmer rheostat. You can either just use ignition switched power for the tachometer illumination wire of you can use the illumination wire on the radio.

My Thailand-spec Yaris uses electronic dimmer circuit built within the instrument cluster.

You have to toggle the trip button while having your lights on to access this function.

Hi all. I'm planning to buy and mount a tachometer and water heat gauges on my Yaris 2007 Sedan. I've seen some loose wires and harnesses near the engin. These are unplugged . My yaris is number 2. It comes without RPM and Water heat Gauges. I bought it in Sultanate of Oman. My question is: does Yaris come with ready harnesses to plug and play my gauges? Otherwise, could you please show me how to mount them? What and where are the right wires located?
Thanks in advance

hey man i was wondering if you could tell me how to go about installing footwell led lights to be activated with a switch prefferably in the center console by the e-brake. i know you have to bypass the firewall somehow for power, but i have no idea how/where to do so. help would be greatly appreciated.

Where is the wire for the seat belt alarm?

The driver's side one is under the driver's seat and then it goes under the center console directly to the SRS ECU. The passenger one is under the passenger seat and it goes to the Occupant Classification ECU and then that ECU communicates with the SRS ECU to relay the info.

What exactly are you looking to do with that wire?

So does that mean if I want to steal a yaris like they do it in the movies I need to cut the yellow, pink and black wires and tap the yellow leads against the pink and black?

Look at my remote start wiring guide for where you can grab the parking light feed. Just verify that the wire colors match, as the Yaris in your market may be wired a bit different.

CTScott do you have a wiring diagram for the 3rd gen Yaris? In particular I'm interested in the body ECU and what wires go where.

Im planning to add a gauge 2 cable for my amp on my new car from the battery, however, I'm not sure where is the right place to do so. Do I have to drill the firewall?

There is no power feed inside the cabin that you can connect that large of a wire to. You can go through the large grommet that is behind the battery, rather than drilling the firewall.

Looking to add power to an aftermarket backup camera. I've searched for over 3 hours for the location of this wire. Here's a picture of the connection for the left rear light assembly on my 2008 Yaris Sedan. Anyone know which wire?
The wires going into the rear lights are: purple, green, orange, white w/a black strip and light blue.
Many many thanks!

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.
