If you're still stuck, list up the wire colours of the plugs.

Crank sensor is on far bottom left. This one is critical so make sure the insulation is good and the wiring has virtually zero resistance between the plug and the connection at the E-DIS module or ECU (can't remember which but fairly sure it comes down to the E-DIS).
Any EFi/CFi/SEFi injection speed sensor can be used - it loves on top of the gearbox where the speedo cable screws in and the cable then screws into the top of it, and it's used to keep engine revs up while moving along (supposed to make low speed driving smoother) - it's not vital for the engine to run well.
Last point - make sure you use the FRST inlet air temp sensor - it uses a Weber (injector-style) plug instead of the Ford one used on the ERST and n/a engines - if you've got the wrong sensor, your engine will run pretty flat as the ECU will retard ignition far earlier than it should.

It is but locates the ECU in a real awkward place. The EEC ECU's are not weatherproofed like the original RST ECU's.
It Also means you have to splice the ERST loom of its wiring.
Thus leaving a dodgy looking engine bay.
However, your right, it will work.

deffo the amel 1, called a 'boost control valve' in the haynes
on mine the ecu is tucked behind the battery
works but not ideal, in the car via a xr3i efi loom would be better, when i done it, it was just to get the car mot'd and i didnt have a erst lump to hand but i did have a frst 1
mite go back to erst when this lump blows, which im sure it wil

PassionFord Post Whore!!
the speed sensor actually leans off fueling at certain revs according to simon @ SECS tho
dunno how true this is
but it was meant to be there so i let it be
