Have a look on passion ford website, someone listed all the ecu pins and wiring, might help?

Problem is i just cant read a wiring diagram.. I'm sorry, but I think this is a bit lazy... You usually get a more helpful response on forums if you educate yourself first (e.g. by googling "how to read a wiring diagram"...), and ask for help once you have more specific questions.

Yeah..tanx mate..I've been Googling for days now but cant find any real answers....I read agood while that theres only a handful of wires needed to get it to run...I've rebuilt the engine and box but wiring is wizardry to me....the manuals just confuse me...sorry for being lazy..!!

Are you trying to run the engine out of the car to check it before installing?
You can just compression test it. A leak down test is similar but more advanced.
If if has compression it's probably a good motor. If you've got a big end bearing failure that'll show as reduced compression on the bore on question. So you can tell a lot from that.
Most other failure points are external, things like fuel pumps and ignition controllers.

It is only around 4 wires to get it to run, BUT if you cant read a diagram your going to struggle. I would advise you get someone else to wire it up for you, otherwise you run the risk of burning things out.

I've seen a guy burnout his car and garage by wiring something badly. Think a small fire got bigger when some fuel was ignited. Not a good idea to mess with wiring if you're not confident.

Tanx guys..as i said its fully rebuilt...it was driven to my mates yard then stripped 10 years ago...forgotten where a few things go, mostly vacuum pipes..and the haynes manual doesnt show diagrams of these I've studied the wiring diagrams in the manuals but i found some wires are not even in the diagrams...

If jackstowage deliberately chooses to be lazy that's up to him, but it annoys me no end when people doubt others' abilities or discourage them from trying something new. Even professionals or experienced hobbyists make mistakes and do stupid things, so that's a fallacy, and surely not a reason for not trying. Alternatively, I would encourage jackstowage to read a simple auto electronics book like the Haynes Automobile Electrical Manual to get a basic understanding of automotive wiring and diagrams, and then just give it a go. To make the diagram a little less intimidating it may be an idea to highlight the relevant wires with coloured markers (wire colours are usually indicated in the legend), or/ and start by eliminating everything that's not relevant (lights, horn etc.) in Photoshop, or with correction fluid if you're working from paper. I would describe my own electronics skills as very basic, but that doesn't stop me from trying to improve them. I've been fighting 12V DC electronics all day today myself because I want to make something that I can't quite get my head around yet, so I'll keep experimenting until it works. Yes, it's very frustrating at times and I run the risk of burning the house down, but I'm sure that a) the feeling of accomplishment when finished will be worth the struggle and b) doing this will help me do more complicated electronics projects in the future.

Trying to improve your skills is one thing, frying an expensive ECU or worse still causing a fire is another. I'm all for encouraging people to learn how to do new things, but start with basics and work up from there. Jumping in at the deep end with something that has the potential to cause big problems if done incorrectly is not a good starting point.

I CAN read wiring diagrams (and draw them) but still struggle to translate what is documented in Haynes manuals to action in repairs.

Yeah..when i turned 60 a couple of years back i got very lazy.... I assure you that i'm not.....i'm the opposite, cant sit down for 10 minutes without thinking about the next project..ask Kevfromwales if he ever reappears .. Sometimes you just cant see whats straight in front of you.....if you can decipher a wiring diagram fair play to you....its magic to me... Have a lad coming on wednesday to have a look..see what happens...tanx for now...

Is it from a Sierra or Granada?
Granada is much easier; there's a red wire larger than the rest, which is a permanent live direct to the battery
There's a relay which the ECU switches on; its output wire is the fuel pump.
Then you need an ignition switched live to power up the ECU. I don't remember what colour it is, but brown and white rings a bell.
The plain green wire is the rev-counter feed.
All of the sensors, injectors and ignition are integral to the engine loom and just need to be plugged in.
In a Capri, the battery feed fits on the starter motor stud, 2" hole saw through the bulkhead allows you to use the large wiring grommet, and the ECU velcros on top of the glovebox.
Temperature gauge, low charge and low oil pressure are separate from the ECU wiring.
Sierra does all the same things, but you have to separate it from the fusebox and loom

Tanx mate..what i have is the injector and sensors loom on top of the engine..the main engine bay loom that plugs into this and the auto box....A long fuse/relay box and a square fuse/relay box...everything i have plugs into something but there seems to be a few plugs missing at each fuse/relay box..i'm assuming that they are the lights, seats etc... The main issue i have is that the Haynes doesnt even mention some of the wires on the loom ECU plug..i.e number one pin is a black/gray wire..but no mention...theres a few like that...I cant find a wire that might power up the ECU....i'll look at a brown/white one... As i said theres probably a heap of wires i don't need.....
Yes its a 1994 Granada..

Quick update on this and a WARNING ... Lad arrived today to look at the wiring situation...long story short ,the insulation on probably 75% of the wiring in the loom had perished, cracked and just fell apart as we stripped the tape and plastic cover off the wires.... I'd hate to be driving around with this going on.....he reckons he'll have it sorted out no problem....
