As this is locost builders there are some people left that love to tinker and make things.
This is to give those people that are interested in running a ford efi engine on a budget a little more info on how the Immobilizer can be used out of
the donor car.
The key to using the the ecu is the Pat's immobilizer. You must get atleast one key with chip that is matched to the ecu.
You can not bypass it but you can use it.

“DLC” Diagnostic link connector.
The obd2 plug is found under the steering wheel. The plastic body should be unclipped from its holder and cut from the Mondeo with as much wire as can
be pulled free.
The tape covering the wires can be removed.
You will be left with This.
The pin’s are numbered as below.
Not all pins are used.
Pin out’s of the Dlc plug, these go to your harness plug.
2) To pin 16 (grey) on ecu plug.
4) To earth (Chassis).
5) To earth (chassis).
7) To pin 13 (white/blue) on ecu plug.
10) To pin 15 (blue) on ecu plug.
16) To switched 12v fuse box.
Pats indicator. This is the led that is usually found in the clock of the Mondeo. Its job is to show you the status of the immobilizer. Ford’s Passive
Anti- Theft- System ( PATS )
Just one Pin from the ecu plug, No 42 (black/blue). This is a switched earth. Take one Led, colour of your choice. You need one that is pre wired
with a resistor. This is mounted in your dash. The negative or black wire is connected to pin 42 of the ecu plug and the red or positive wire is
connected to the permanent live.
The Immobilizer.
The picture below shows the transceiver or aerial. This is found behind the steering cowl. The ring sit’s around the ignition switch and is held to
the steering column with one screw.
This is the wiring plug.
It needs cutting from the car with as much wire as can be pulled free.
Retaining clip shown at the bottom.
There are four pins, They may be colour coded as above or they may be all black as shown in the photo. This depends on the age of the donor.
Pin 3 to pin 19 grey/orange -- Pats TX signal.
Pin 4 to pin 53 white/green -- Pats RX signal.
Pin 2 is the earth, to chassis.
Pin 1 is a switched 12v.
All four wires will need extending from the harness plug up to the steering column.
Fuel pump relay.
The Ecu, both controls and monitors the fuel pump via a relay.
There are two pins from the ecu plug.
Pin 54 (black/blue) from ecu plug, Fuel pump relay control switched earth.
Pin 40 (violet/black) from ecu plug, fuel pump monitor.
Starter motor inhibitor relay. This stops the engine from cranking as part of the immobilizer.
Pin 27 (black/yellow) ecu plug -- starter motor relay control (switched earth).
Hope this helps any one wanting to run a zetec without spending shed loads. Its no harder than making a loom for a MS ecu. There is no mapping and the
ecu can be had for a few quid.
I just want to add a massive thanks to Warren and the amount of time he has put into this. I have mine running this exact set up with help from
Warren. He has always been willing to help with questions. Thanks mate!
(PS Warren I still have the bell housing for you, and will drop it over soon!)

Great drive ability much better emissions, better fuel mpg and much cheaper than bike carbs.
My ecu and loom stands me less than an edis4 sells for on ebay
Drivability and MPG are good [I've already got bike carbs], though I'm sure OEM efi would need less fiddling about with.
My question was more about how much less power I might have with an OEM efi set up compared to 4 x 38mm mikunis, which I know is an impossible
question to answer but was interested to know other people's opinions.
Greetings from Finland.
First i wanna thank you for that information.
And then the guestion, what should i do with the vss (vehicle speed sensor)
Someone told me that i cant use original ecu because of pats and vss.
Im putting 1.8 zetec from 97 Mondeo to 75 Taunus coupe, gearbox is gonna be t9.
Thanks and sorry for my bad english.
Taunus 2.8i automatic 78'
Taunus 1.6 77'
Taunus coupe (zetec) 75'
Sierra 2.3 V6 82'
Language, I can only just about speak English so you are way way in front of me on that score
Yes lots of people will tell you, you can not use the ecu because of the pats but there you go.
I've run them with and with out the vss and can not tell a difference. One car I wired up passed iva emissions with no problems at all with out
the vss signal. The reading I've done says the ecu uses the vss to cut fuel on over run ie coasting to prevent dumping un burnt fuel down the
exhaust and into the cat.
Long term running with out the vss signal will show a code in the ecu. The early ecu doesn't have a MIL light or the over cautious Limp home
mode newer ecu's have.
I have now gone back and connected the vss up using the sensor in my MT75 You can also get an adapter to run a Mondeo vss sensor on the Type 9 if you
have the space in the tunnel.
Its a Hall affect sensor. voltage (5v~12v) earth and sense. The signal feeds both the ecu and the speedo in the dash.
Thanks for answering.
Maybe i try without vss first and get the adapter if it doesnt work.
1 guestion about the adapter, can i stil use original cable speedometer from Taunus with the adapter?
Id like my original gauges to work, heres pic of them.
Like it says in the first post, the info is for the ecu that is named but the info can help you work out other ecu's but I havnt done every
ecu.

Watched some of your videos from youtube, looks very nice
Btw, my ecu pinout looks same than that 'owls' but it says 'noah' is it the same?
i just acquired a mondeo 1.8 as a donor it cost me £150 so since it came so cheap i am looking to see if the original ECU is reusable. its a mission
to see how cheap it can all be done and still be viable.
the inlet manifold is bulky and in the way of my steering column, so if i remove it and fit something slimmer what effect does it have on the
management? is the Ford ECU reprogrammable to correct it? or is it best to keep the standard inlet manifold?
sometimes you are the pigeon, most of the time the statue.
Then you have most of the parts you need for a Budget zetec install.
As with anything Cost reduces with the amount of stuff you can make and do for your self.
In theory the ecu can be mapped, flashed or chipped. The reality is if you intend to do this you may as well start with aftermarket management due to
cost over gain.
The ecu handles small changes very well. You don't need the inlet manifold for it all to work as the ecu does not see a manifold it see's
sensor signals. The key to having the ford ecu run well and cheap is you need to use the sensors.
There are lots of ways of getting around the plastic manifold.
I've run a very compact Log manifold that I made with the Tb stuck on the end. Do a search for Ginetta / Griffin zetec manifolds. Neither are
available now. Gbs do a nice one But none of these had mountings for the standard Idle control valve and this really does make the car start and idle
like a factory car no matter what the temperature.
There is a chap on here that ran his with bike throttle bodies. just a case of sticking a plenum on them so you can stick the maf on the front for the
ecu to see load.
You could even use the up and over cast alloy manifold. The top sticks out of the bonnet a bit but can still look good.
Up shot is, the standard 136ps spec 2.0 engine with free flowing exhaust and inlet will give 150bhp at the fly' And the same engine with jenveys
will give 165bhp so 15bhp will cost you £2.5k by the time its mapped. To get more from a zetec requires headwork and cams. (This has been dynode to
back this up but not by me.)
