Wiring Schematic
Hi Guys,
I have a 2.0l Zetec with what I am told is a mk 1 focus coil pack " dont take as gosspal"
It has a 2 pin connector on the coil unit, a sensor on the exhaust etc. Where can I get a schematic for the engine etc so I can create my own?

From my understanding (see the post I just put up) every coil should have a live feed (the voltage required will depend on the coil) going into one
pin. The live feed can be common between all coils. The earth is then controlled by the ECU, individually for each coil.
If disfunction is a function, then I must be some kind of genius.

Hi ya,
There isn't a coil etc, just one ECU with all the HT leads coming off it.

I suggest you post a picture of what you are referring too...

Hi,
This is the coil.

So it's a ford coil pack, it has two coils inside. Fords run a wasted spark system so two plugs are fired at once. The plug has three pins not
2. The centre pin is 12v and the other two are switched to earth by the ecu.
The white box has a single pin. It's a 20uf suppressor. The centre pin is also 12v, the same 12v as the coil. It earths though the bracket.

Great stuff!
Is there a schematic for the whole system with the ECU etc?
Should it be a none standard ECU?

What ecu have you got ?

Not really, there are hundreds of pages of them. Picked out a few for you, look for 'Ford Wiring Diagrams'.

Hi,
Not sure yet as I havent found it, guessing its behind the dash.
I am stripping the car and rebuilding it so will be all new wiring etc (I design electrical systems for cars etc as a full time job ;0)
so I would like to draw up a full vehicle schematic and get one of my suppliers to build me new harness etc so a schemtic of what can be done with
this engine, that coil pack and what ECU is best to run it would be fab!

There is a sensor in the exhaust manifold, what looks like crank sensor but did seem to have a camshaft sensor connected.

What you have there is a silvertop zetec.
These where fitted to a Mondeo in 2.0 format, the focus came along with a black top.
The ecu in the mk1 Mondeo is behind the header tank. Depending on the age of the donor it could be a 60 pin eec-iv or the 104 pin eec-v. Again
depending on age it could have the pats system or not.
To sum up there is no complete schematic due to volume and variety. It would look like spaghetti.
Find out what ecu you have and there is more info available http://www.locostbuilders.co.uk/viewthread.php?tid=179921 but I would think again about a
100%new loom as half the plugs are not available.

Cheers will look behind the dash.
Dont think it has pats as there is no key at present to start it.
New harness is easy for me, all the terminals will be readily available to me so if I can not get a new connector, I will de-pin the old one.

Some more info would help with answers.
Is this a Mondeo ?
What reg is it ?

Hi ya,
Its a kit car I bought and the guy had no idea what he had lol.
Car ran but not sure how well as only saw it on tick over. It has R6 carbs fitted.
Only thing I found so far are:
Crank sensor (I think, located on engine near to bell housing)
Sensor in exhaust.
Coolant sensor (Not sure if for ECU or temp gauge yet)
Coil Pack.
No sign so far of PATS. No throttle pedal position sensor, Cam sensor looked not connected.

Hi,
Just found the ECU, its a 12 pin ECS module.
So better to convert it to a 60 pin ECU or the 104?, which is better and is the way to use these without PATS?
Many thanks for your help!

Neither are ideal if you're keeping the bike carbs both do the same thing if running the injection.
It would have to be a very early zetec ecu to avoid the Pats.
97 on gives you obd2
2001 on has dual o2 sensors.
Again more info needed for a more complete answer.
Does it need to be Iva'd ?
If yes what year was the engine made ?
How much do you want to spend ?
How much power do you expect ?
How much skill do you have to fabricate stuff ect ect

Hi ya,
I can make anything, have fabs made etc do no problem.
Hoping to get it IVA.
Power wise, not to bothered, standard type for 2.0l would be fine.
Is there a way to find the age of the engine from the engine it's self?
If keeping bike Carbs, what's the best route?

Yes the engine number will tell you the age. It's down near the crank sensor.
You can look it up on Burton power web site.
If it's made before August 1995 then you don't need a catalytic converter and will get an easier emissions test and will get away with
carbs.
After aug 95 you need a cat and have the tougher emissions test. Forget carbs, you need fuel injection. The oem set up sorts this nicely and is
very very cheap but there are packaging issues for the inlet manifold. You can make a manifold or you can move the steering column down link and
chassis cross brace.
Of coarse if your pockets are deeper there are lots of plug and play bolt on parts. The deeper your pockets the less you need to make and the faster
it will go.

Fantastic, getting clear now!
I will check out age of engine.
guess that's the biggest issue, pre 95, carbs and Nordiz is good. Or do you think the current ESC with the vac pipe connected be ok?
If its post 95 then need injection etc.

The Esc properly set up will run but I couldn't tell you if it will meet the test. It has a 3D ignition map that is based on an 8v engine where
the burn characteristics are differant to a 16v engine.
I can tell you the oem fuel injection will pass the test.
As will other options. But that will be down to mapping.

Hi Ya,
No engine number! No signs of grinding either so no idea.
Other numbers on block are:
I think 04L97
6015
C8S1A
On head I think 958M-6090-CC
Any luck wih them?
