Help - ECU PINOUT Diagram

Hi people.

I'm Installing a AEM F/IC in my focus ECU.

Please, I need the pinout schematic or diagram of the ECU. Does anybody
has ?!

It´s a focus 2.0 zetec and the ECU is an EEC-V.

Thanks!

Bruno

Thanks a lot!

I'll try the AEM....if It not support my car, i'll change to SCT Flasher, but i am asking my self if the SCT will work on my ECU, because yesterday I took off my glover box to see my ECU code, but it was made in brazil and seems to not have a code like the eec-v from US.

So which one of these pins do I cut into to connect my Autometer Tacho Adaptor into? The instructions say cut into the 12v supply to the coils It's a 2L focus duratec ecu.
Would appreciate any help.
Thanks

Can't do it.

You're looking at info for a different engine to begin with, and the focus uses constant power to the coils with the ground being an intermittent through the ECU/PCM.

Look in mod sections for your model for information, a "tach. driver" is the best way IF you have to have an aftermarket tach.

Most swap in a tach cluster instead, for MUCH easier installation.

Thanks Sailor I think I'll just have to manage without until my new TB's and ecu with a dedicated tacho output arrive. I'm swapping to single coil so it should help.
