nope, you don't need the oil & temp sender loom as that is the same for all mk2s. (apart from the blue temp sender, which is for the ecu)
The easiest way to get what you need is pull the ECU out, and follow any wires joined to it, to the fusebox.
You'll need the loom and sensors for:
ECU
Hall sender
Injector rail
Blue temp sender
Coil
TCI unit (above ECU)
If you want the MFA to function you'll aslo need the oil temp sender, outside temp sender and a vacuum pipe to the back of the clocks. I'd concentrate on getting the engine running first though
