i think!!!!!!! this is right and im sure rob will comfirm it.

Black/white is +12v and the black with it is earth or EC36pin26

white goes to EC36pin13 = trig 1
black goes to EC36pin27 = trig 2

From the workshop manual we have the following schematic:



Ref and Pos are shown in the manual, but we're using the outer slot as the primary trigger (EC36pin27) and the inner single slot as secondary (EC36pin13).

If I were doing this loom I would get the grounds, power and flyback sorted, then get the cas wired first of all, then I'd be able to test the cranking RPM. 
Then I'd get the coils connected so that I could time the whole thing in.
Then the inlet and coolant sensors.
Then the MAP sensor.

And once I had everything hooked up I'd connect the fuel and see if I could start the car knowing that everything else was in place.

I'd not fit the wideband until the thing was idling - you'll be amazed at the amount of fuel that you can throw through your engine when starting this up.
