This is my cluster showing the cc icons.


So I have to run the wire from which hole in the connector?

What else do I have to do, I already drilled the cover, plugged the stalk wire and bolted the OEM stalk.

I was really hoping my '10 AT had all the wires in place. Not at all.

So, you definitely need to add the connector D3 pins. The other question is if the ECM connector A21, pin 40 is present? On Puerto Rico spec cars, it is, but the D3 pins are not.

Am getting a little nervous about this, I unplugged the ECM connector A21, looked at the pin 40, small pin by the way, and looks like there´s nothing there, just the empty space, It was late and dark, of course I´ll double check at lunch time.

Now my concern is with my ECM, in theory I have the one used in the canadian Yaris (89661-52G71), but, what if there´s nothing on my ECM to receive the wire in the ECM connector A21 pin 40? would that mean I have the cruiseless euro type of ECM (nooo please)?

Oh boy am in panic.

89661-52G71 is a US/Canada spec ECM, so I am sure that you are OK. I should have made you check the ECM and connector D3 pins before I sent you the stalk.

Hey CT you have been of great help, definitely my bad, since I have a ´10 I tought I had the wires in place and I was lazy to unbolt stuff and take a look.

Ok, so my next step would be Vince87´s method right?

I already downloaded the PDF and read the entire thread.

wire from AD3 to ECM connector A21 pin 40 right?

Correct - Wire from A21-40 to D3 and D3 to ground. I can mail you the pins (ECM pin - $5, D3 Pins - $5). USPS to Mexico is the same as to Canada, so there would be no extra charge for me to ship them to you directly (rather than to your US address).

Wow, sounds great.

Do you know if USPS offers a faster shipping speed?, I am willing to pay a little more for a faster shipping and get this done.

Priority mail (6-10 business days) would be $13 more and Express mail (3-5 business days) would be $30 more.
