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.

Ok, I think 3-5 bussiness days are too many days (expensive too), I am going to buy some 20-24 AWG wires and try to make the connection myself. Are these wires made from many thin wires or 1 thick one.

If I can´t make it work, I´ll order them from you.

Sorry for so many questions I do not have electronic experience in cars.

I am very grateful, Thank you.

For testing purposes, stranded wire should work. You will probably not find it to be reliable for continued use though, without using connector pins.

After picking up the envelope you sent me, today my quest for CC continues.


It is clear for me that the lengthiest wire is the one that goes to the ECM (ECM pin 40-D3 connector).
One of the two short wires you sent me is for ground and there's another one that I don't know what it is for.

It's not been clear to me on vince87's DIY pdf all things related to D3 connector, One wire to the ECM, but about the other two, where do I plug the wires that connect in D3 ( the other end of the wires), if one is ground, what about the other. The small one that is not ground go from where to where?

Sorry if am asking dumb questions I just want to do this right.
