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.

Hello! I have an alarm to put on my Yaris (from 2002). Where i can find a diagram of the car with that?

[AlexNet0]

use a multimeter and probe the wires, and make your own diagram, thats what I did when I installed my remote starter.

[Sora65]

But where im getting at is right?
i could put the wire i need powered in the same hole as the blue one where theres 12v?

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!

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?

Yes. That blue +12 is always on though. The pink is switched ground for the inside lights.

There's a 2 pin connector to the engine coolant temp sensor. It has a pink and a blue wire that go to pins 96 (pink) and 97 (blue) on connector C20 of the ECM.
