Hi folks

I think I have made a schoolboy error.

I am trying to get a Zetec to run on its original ECU with PATS using a ECC-V ecu. Form info on this forum it looks like it can be donewhich is the good news. However when I obtained me 2.0ltr black top engine (Engine code NGD...) I go the keys and transponder ring but not the Dash module.

After spending the day with the wiring loom and wiring diagram it looks like I am missing the vital part, the instrument cluster. Am I right in thinking that the instrument cluster contains the Instrument Control Module (ICM) and the ECU nees a feed from this to run?

Also is the ICM coded to the ECU/PATS so I need the instrument cluster from the same car as the ECU?

If so It looks like the engine will not run. The car I got the bits from has now been crushed so I guess I am looking at a not runner.

Any suggestions before I start looking at a megasquirt unit

there is a chap over on the haynes forum that has managed to get it all running may be worth posting up on there.

As far as Im aware you dont need the instrument cluster. Mine is wired in using original ecu and pats. Almost ready to start (this week hopefully). You will need a relay to run the high pressure fuel pump and a relay to operate the starter inhibitor, along with the right sensors on the engine. If I remember rightly you need, Cam and crank sensors, TPS, air flow meter and O2 sensor, may be a few others but its a bit late for me to remember.

Once mine fires up I will post up. Also there are others on here that have done it and got some good results. (big_wasa)

Thanks for the swift reply.

I understand that the earlier ECU ECC-IV will run without the instrument cluster but the later one (EEC - V with Pats) will not.

Are you running the early or late one.?

I have got all the sensors and wires from the Bulkhead plug forward.

Keep me posted.

A friend of a friend has just offered me the bits out of his mondeo he is stripping for banger racing.

Does anyone know where the instrument control module is located so I make sure I take the right part this time.

I have the eec-v with pats, no instrument module.

all I have is:
OBD
PATS key and aerial with PATS L.E.D indicator wired in (usually an LED in the mondeo clock)
ECU eec-v
Cam sensor
Crank sensor
Lamda sensor
Airflow meter
Throttle position switch
Coil
Water temp and temp sender

Thats it. All wired in and running.

I will post a video to it starting up so you can see it works

Andy

You star. I looks like I have got all those parts. What year is your set up? someone told me that I do not need the instrument cluster until 2004 but was unsure.

But what did you do with pins 10 and 79 to the instrument control module? Did you just wire the LED into this? Hence is the instrument control module just an LED?

What voltage is the led as there is no info in auto data?

Thanks for your help

HI

Mine is all from a 1997 Mondeo. I will see if I can find out the pin 10 function later. Got a busy week ahead so not much time to get in the garage :-(

Andy

Thanks for your help if you can let me know your engine number I will compare the wiring diagrams to see if there is a difference between the two but I am aware that some of the pinouts changed over the years.

I have got a copy of autodata so it should not be a problem to compare them with the engine number and save you some hassle.

Thanks for you help

Andy

I have been looking at the wiring diagrams for engine numbers NGA to NGD and it would appear that they are all the same in respect of the ECU main components. So if you have got it to run it appears pin 10 and 79 are the key.

It would be a great help if you could have a look at the weekend.

Thanks for your help

Hopefully get out to the garage on Saturday (thats if I dont have to go to a kids disco ) so will have a look at let you know. I should post the start up video later today :-)

Anyone know what this does from the mondeo loom before I cut it out.

Looks like a relay but can find it on the wiring diagram.

Andy

Iam still confused. you say you need the following:


PATS key and aerial with PATS L.E.D indicator wired in (usually an LED in the mondeo clock)

I can not see a PATS LED in the wiring diagram. What pin no does this run from and does it run to earth after the LED or back to a pin on the ECU.


thanks

I'm going through exactly this same exercise at present, and big_wasa has been a great help to me over the ecu wiring.

Pins 19 & 53 are for the pats tx & rx signals respectively.
tx is grey/orange; rx is white/green.
You should find these match up with 2 of the wire colours on the transponder.

Pin 42 (black/blue) is for the positive side of the pats led.

AndyW mentions using the coil connector. My understanding is that you only need this if you're running an aftermarket ecu rather than the standard eec-v. Someone please correct me if I'm wrong here.

I'm also intending to make use of pin 83 as my setup has an idle control valve. Folk say this is a good idea, though it's not essential.

Pins 10 & 79 are unused on my ecu connector.

HTH

Thanks for the help.

Pins 10 and 79 are not used on mine either.

pins 42 and 43are listed as the trip computer which is what was confusing me.

Just so I get this right. The blue black wire from pin 42 is wired to the positive side of a 12v led. The other sode of the 12V led then goes to the +ve conection on the pats ring.

-ve of the pats ring goes to earth anywhere and does not need to return to the ecu.

Pin 42 is not required?

I had taken a permanent live off the ignition switch to the +ve of the pats ring and ignored pin 42 as I thought it was involved with the trip computer so not required. I guess this is wrong and should be as above.

Confirmation on this would be great as the rest is wired ok I hope as it seemed to make sence.

It running thanks to Big-wasa who has been a star.

I will post a video later!

Here is the start up of my engine running EEC-V ECU and PATS with no small amount of help from big-wasa

Hope the link works as it is the first time I have tried to post a youtube link

Great news.

Easy isnt it

What dub box is that and how have you adapted it to fit the ford lump ?

Its a real winner I have been so against running the engine on carbs from day one but everyone has been encoraging me to take the easy route. I always thought it was the answer for a road car.

Had a minor problem in that it ran rough after I took the video. The fuel pump sounded rough and I don't think it was cutting the mustard. I swapped it for another I had lying about and it sounds much sweeter. Result. I have got a new bosch one but none of the correct fittings so should be ok when installed.

The gearbox is a VW camper/beetle box. It is a 091 six rib so should take the power. The bellhousing is form a Mondeo which I cut in half to remove the diff part. I then machine part of the gearbox side off and had an ali plate welded on. We then machined the ali plate to the original VW gearbox bolt pattern. The clutch release bearing is all Mondeo and the clutch plate is a Mondeo one but made with a VW centre boss. It bolted up without any problems.

I am hoping I have got a VW Camper with nearly 3 times the power that has a reliable engine so does not spend its time on the hard sholder. The alternater is off a Volvo S80 140amp so should run a split charge system with no problem.

I retrospect I should have left the mondeo alternater in place nd just fitted a smaller second one for the leisure battery.

But you live and learn. The rad is going under the chassis rails. It may have a heater that works as well as it is water cooled.

However I would have been half the camper without your help.

I was also using this as a experiment as I thought I could fit another Zetec in my Elan +2 as the box will bolt up with no problems.

Will the EEC-V ECU handle mild modifications like throttle bodies and mild cams without objection or does it need a remap or chip to extract more power. I think the Focus ST170 runs the same ECU so fow does that get 170bph rather than 134bhp with the same ECU.

As long as the ecu see's the sensor values it will run throttle bodies but you need an air box so you can use the Maf. A differant Tps seems to give a flat spot due to differant values.

Do a search for Will on here who has done this with a pre pats in a fiesta..

Good exhaust mani', free flow filter and you should push 150 with what you have. All just fast ford stuff.
A plenum with trumpets and a single Tb will be as good as it gets.

I havnt had my hands on an st yet to play with. There is some info on the net that says its not as easy and has a higher levell of security (black oak) ?

It will be much much harder to get newer can-bus setups going.

Any one want to donate a loom, ecu and keys ect ????

I will ask about for a loom etc as I think the banger guys have got a damaged ST 170 to race. They will not run it on an ECU so may be able to get hold of one.

Is Black oak another Ford security system?

EEC was superseded by the Visteon 'Black Oak' ecu circa 2000. It looks the same.
