why do u keep asking ppl on here when avinitlarge is the only person who has done the conversion? other forums have loads of ppl who have done the conversion, youd get info alot easier out of them,

id help u m8, but im not sure about that

LOL, You use 90% of the fiesta loom and about 85% of the mondeo engine loom, Its alot easier said than done, Even thought i am an electronics engineer it still took me a while to do and I admit, I made mistakes and had to strip it down again. Its not an easy job if you dont know whats what

LOL, No, You NEED the fiesta EDIS, You also need the fiesta turbo ecu, If you are using the XR2I loom you will need an OFAC ECU and fiesta turbo map sensor, I am selling my OFAC ECU, Stage 1 superChip and MAP sensor soon

Any EDIS4 will work, As for where things go, The only thing to do is to look in my gallery to see if there are any pics

and do i use a std map sensor from a xr2i.i no how to turn the xr2i in to ofac and ofab.so its just the case of matching the remaining wires from the mondeo to frst loom am i right.everything matches except they will be 2 or 3 wires remaining.am i right so far,if not put me on the right line.

no, you need the ofac map sensor. you need to strip alot of the mondeo loom out and join the fiesta loom in. You need to keep it the same shape too

No, You take all of the mondeo ECU wires out of the loom, leave the rest, Temp,Oil. There is just too much to explain. I dont mind helping, But you have got to try and learn how to do it on your own, I had to, Not just the wiring either, The WHOLE lot

I still kept the mondeo temp sensor and oil pressure switch wires, The rest is fiesta. I used the fiesta co pot, I think ive got a spare too, Ive got 3 or 4 EDIS4 modules but they are for backups

my oil light wire is on my fiesta loom shall iuse that.just thought of somthing.when i match the fiesta plug with mondeo plug on the injector harness there is a couple of wires left over witch would be from the thermostat which is situated on the top the thermo housing is that right.and maybe a few from the egr.dont be shy mate send me a co2 pot its for a good cause.im copying ur engine design but might use the efi inlet from the xr2i with an adapter plate from oddkidd .
