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.
