i,ve just got an rs2000 engine, engine bay loom, ecu and fusebox to put into my 1.6 zetec escort, not the most exciting conversion i know but its a step in the right direction

what im wondering is will the ecu plug be the same and will the rs engine loom splice into my zetec in car loom and still work?
i presume all the engine sensors are differnt in the two engines are different
trying to figure out the wiring cos the c*nt i bought it off said he had the full loom but turns out he didnt, only the engine bay half
doesnt matter though ive only paid him half
any advice experience or knowledge on the job greatly appreciated
thanks
Alan
