escort mk4 xr3i efi-2.0l zetec conversion, help please

I used the entire zetec engine loom, spliced a few wires from that big multiplug into a mini fuseboard for lambda fuse, ecu fuse etc that are obviously not in existing fusebox. Then run it though a yellow fuel pump relay and ignition relay, hooked it up to perm live, ign live and fired it up 
only other thing you have to do is hook up an earth to the temp guage multiplug. some people use a cvh sensor and the old wire but I don't see the point when it's just a case of splicing in one wire as opposed to swapping sensors. Then if you have mfi, you need an efi rev counter, hook it up to the coil pack or edis module and watch it hit 7k
Then when I'd got mine running, a few weeks later I met rich (xr4x4rs) and we did his loom the same as mine as he was having trouble trying to use his efi loom.

im looking at doing this with my mk3 escort. which "multi-plug" are you refering to? the one identical to the fuel inj loom plug?
run what through a yellow relay, what wires?? all the lambda, ecu etc wires? or another one....

It's the multiplug that seperates the car loom from the engine loom, instead of going to the donors fusebox and instrument panel you wire it to your recipient car. All the info is in the haynes manual wiring diagrams for the donor car, you just have to take the bits you need into the other car an replicate where there used to be a fusebox etc and build yourself a self enclosed engine loom. I've typed out so many times how to do it that if you can't find a guide or decipher the diagrams or whatever, just go on XROC forum and you'll find a page where I sell a loom ready to fire the car up whether it be in a mk3 escort, caterham, or on a bench as long as you give it 12v and flick the starter.

Yellow fuel pump relay is the one you use as I think the mfi uses one pin as a prime function on the pink one, whereas eec-iv primes by the ecu letting the fuel pump relay get earth given it's required inputs. It's just a boggo 12v automotive relay really though so if you've got a duff one or can't find it, don't bother paying ford prices for a replacement ford relay, pick one up at the factors for about 3 quid.

Does it include a fix for the rev counter readout? Mine's not connected yet but heard they only run at a half readout?

Zetec Conversion
Hi there,
I hope you can help me. I am doing a engine conversion and going from 1.6 MFI to 1.8 Zetec on a mk4 escort. Could you please tell me the easiest way to carry out the conversion as you say you have done connected a zetec loom to Mfi before.
DO i use the Zetec Box?
What part of the wiring loom do i need to connect everthing to my mfi loom and what extra fuses are required?
Do i just need the engine wiring and the ECu or complete wiring loom?
I will use the zetec wiring loom and have a lanmda sensor so this will stop it from overfuelling, would I need to use a zetec down pipe and weld it to my cvh exhaust?
Apologies if you have been asked this before, and if you have answered the questions already please point me in the right direction.
Cheers.

basically the complete engine loom off the zetec you got the engine out
you will need to make a little fuse box and have n igntion relay in there then u just link the fuel pump wires to ur fuel relay
like i said go onto xroc website look for someone called sex3i or something he can help

OH NO!!!
What kind of injection do you want to use on your 2.0? 1.8 130 hp or 2.0 Mondeo...
A friend of mine put a 1.8 with whole injection in his 1990 MK4 EFI. Was a straight job. Just took all the plugs off the old engine. There are only 8 cables that must be connected to the Escort, the rest of the loom can stay standard!

The same did this guy with the 1.8:
