ok, after a long hard search i finally found the pinout for the ecu.
there are a few labeled not used, if you know there function let me know so i can update the list. also, if you know what some of the abreviations are on the list (scp, tx) let me know.
as you'll notice pin 48 is already done and it is a verified tach signal (verified it this weekend)...
know i can hook up my shift light...lol

Out Freaking Standing!!! And this applies to SVT as well right? I wasn't able to locate the Oil pressure pin on this or the MANY Diagrams I have. Do you think it's a seperate Stand alone connection? If so where's the sending unit so I can tap straight into that?

ill have to get my manual out and see, but in the manual for my explorer its a standalone wire to the guage. shows the color, but not sure if it would be the same between the two so i wanna check before i say.
and the pinout applies to all foci. some pins just arent used between different aplications. and there is a difference internally in the ecu between a car with auto and manual from what ive found so far. but the pinout applies still.

ok so now i have a question. i have an 07 focus without a tach in the cluster. im hookin an apc 5in tach and so far the only thing holding me back is a useable signal so i was wondering, the ecu i believe i have located in the passanger side kick panel right? well there are 3 plugs going into it and each one has a oin 48 so is the plug closest to the firewall the plug i need or the one closest to the door
Oooohhhh this is gonna come in handy with my megasquirt.

your in the right place, but theres another box mounted on top of the ecu, the ecu is under that
