Hi all

I've just got my hands on a 2 litre zetec lump from a 94 mondeo, the plan is to stick it into my mk4 xr3i mfi which after loads of messing about has just been mot'ed. Im sorted for mechanical parts but am stuggling on engine management. Is it best to source a zetec engine loom and connect it to my current car loom or is it better to go down the route of a stand alone management system, if so what is the best type?

Any help would be spot on as its startin to make my head spin
cheers stu
