Ford PATS Antenna
Hi, I`m building a race car, mondeo, with a focus ST170 engine. All the wiring are removed, and I just ordered the ECU kit included the key and key
holder. The engine are from a -02 model, and today I found the antenna from a -14 model. Is it possible to use a -14 model antenna, or do I have to
buy antenna from the correct model?
How do I find the correct connection for the wiring setup? As I understand the wires are all black on the antenna contact.
By the way, I`m norwegian and I`m sorry for my bad writing. Hope you understand what I mean anyway.
Regards Johnny B

Its not model or year specific or set to the individual ecu but they have changed the frequency over the years so you would stand a better chance of
somthing between 1998 and 2005 mondeo fiesta focus ka Cougar are your best bet.
Pre 1997 are definitely different and don't work

Hi again, and thanks for the last reply.
Now I have connected everything according to the thread "How to" OEM Focus ST170 ecu with Pats info.
The PATS LED lights up for a few seconds, and then starts blinking, and I have no spark when i crank the engine.
For information, the fuel pump and cooling fan is connected trough switched 12v supply, not to the ECU.
Since this is the first try on a project like this, I also wonder how much sensors are needed as a minimum to get the engine started?

If its flashing then the immobiliser will not let it start.

It`s flashing, but after some time (like minutsj it stops. About the led, should the resistor be on the + wire or on the negative against 42 ECU wire?
What does the PATS actually turns off? Can you get spark on the plugs whitout pats recognision of the key?
Another thing, I have the key and antenna ring. Is it important how they are placed togheter? Or will it work as long as the key are placed inside the
ring?
Which sensor will give signal to the fuelinjectors? I`ve assume my fuelrail are from a standard zetec engine, because it has a return line to the
tank. How can i bypass the signal from the fuel rail pressure switch, when it`s not there?
I`m sorry for all this questions, but my son missed out on a race this weekend and I felt pretty bad not getting the car ready for him.

I believe it’s all fuel related because some of the banger racers use them for ignition only. But I’ve never tested it as I want it to work complete.
