I found it easier to go threw the firewall than take out the ecu, iunscrew it, and find the pin.
EDIT: Wire it threw the firewall and hook it up to the grey wire on your O2 Sensor.....VERY easy to do......Only one thing, when Berin and I installed ours, he was getting signal off the black wire and not the grey.
Supposbly this is common with the focus. :unsure:
