I had a look at the connector AD2 (which is more accessible than the ECU) which joins the ECU to the fuel pump and Evap cannister harness: the wires were not there for the Evap cannister (A01G ROM). It turns out that I am in luck and the ECU does not interrogate Evap Pressure in my A01G car, so I don't need to compensate for losing the signal.
Moving on to connector A35 on the ECU, pin 20 was empty and I decided to hook a wire up to it. Pulled the connector out - it turns out that I could use the Molex pin from a scrap IDE type ribbon cable on this. To do this, lift the retainer on the IDE plug with a pick and pull the connector out. The A35 connector has a horizontal locking tab in the middle - that needs to be pulled out about 2mm, then the IDE Molex pin slides all the way down the barrel and does not come out when the locking tab is replaced. See last picture for new wire placement.

I made a serious attempt at getting this terminal into the A35 plug with zero success. I have used the exact same connector pictured, but can't for the life of me get it to click in at all!!!
Would greatly appreciate any support from someone that's connected wires direct into the ECU
