Pop the hood and look to the left:

OK - That's the same as my 09 LB, so the ECM is fine.

Do you have a volt meter and know how to use it?

If you measure the voltage between the blue and brown wires (with the ignition in the on position) at the connector under the dash, you should see 12V. If you hold the on/off switch it should drop to 0V and then pop back to 12 when you release it. That's a good starting point.

I tried to get a read between the blue and brown wires with a digital multimeter, but It dont display any voltage, Im not really sure but I think Im doing it right. I used a Craftsman digital multimeter, put the knob in the VDC section, in the 20 value, and the cables the black in com, and the red in V, mA. I tried in the end of the plug and directly to the cable and nothing.
What Follows?
Thanks in advance.

You have the meter setup properly. The important thing is to make sure that the metal tips of the meter probes are actually touching the metal of the connector pins. You want to go in from the side where the blue and brown wires enter the connector.

Also, make sure you have the key in the ON position when taking the measurement.

Ok, I checked again and there is no voltage reading, I tried the same with another plug in the wiring and got a 12v reading, I think there is no voltage getting to the CC switch thorugh the plug.

OK. The next thing to check is if the ECM pin is actually there for the blue cruise control wire. You can remove the connector (you press in on the gray part and then lift it to release the connector). If you look in the hole side of the connector, you will see that some holes have metal visible and others do not. Check the pin circled below (note that the connector in this photo does not have visible metal, so it is lacking the pin for cruise control):

If that is the case, you'd need to follow the procedure on the first page for the 2008 or older Yaris to add the pin, and then run the wire from it to the blue wire. The brown should be fine, as that one is just a ground.

Ok, but where does the blue wire from the switch should lead? They just cut it on the middle from the cabin to the ECM?

The wire goes from the ECM to a junction connector that is way up under the left corner of the dash. From there a second wire goes from the junction connector to the connector under the steering wheel.

I will be running that wire tomorrow morning then, Do I need the special connector listed for adding the connection to the ECM or could I tested just passing the cable through the space where it goes on the black plug that goes to the ecm?
Do a regular cable connector works? ( the little square ones)
Thanks for your help!!!

You definitely want to get one of the real pins for permanent installation, but you can try the "shove a wire in" method for testing. I wouldn't try any other type of pin, as if it gets stuck you'll have a real mess.

Thanks for your real fast reply, I will try the wire method tomorrow, and order the special pin from the local dealer tomorrow. I will post if it works.

Update:

I did the wiring, but the cruise control icon is not showing up in the cluster, but I did what you told before, to measure the volt, and now is getting the 12 volt, and when I press the On/Off bottom on the stalk the volt drop to 0.1
