Found these on another site and thought they might come in handy.
These are taken from a GTi engine, but I have checked the positions compared to me Quiksilver and they are the same, not sure on anything else though.

That diagram is slightly wrong mind you.

The one circled Pink, is also referred by Citroen/peugeot owners as the Idle Stepper Motor Control.

Green one OK.

Red one OK.

Light Blue one is your Fuel pressure Regulator and has no Idle Air Control, any 16v'ers will notice its stuck onto the end of your Fuel Rail.
Standard is set @ 3.5 Bar but you can buy weber 4 Bar ones which make your car fly but also decrease your MPG. Suppose to be good mated with Pugsport ECUs.
The Fuel Pressure Regulator does have a small pipe which goes to the underside of the Plenium Chamber.
Its mentioned to have idle air control as the vacuum inside the Plenium Chamber affects what pressure the regulator will regulate the fuel.
Different loads, throttle position all have effects on the FPR.

Oh and the Green and Blue Connectors are BOTH Coolant temperature Sensors, one if for your Instrument Panel which includes the overtemperature light.

The other is for your ECU Reference for Cold Starts.

The one labelled Cold Start reference is just the Throttle Body heater.

The ECU Cold start reference (Coolant Temperature sensor) is green 2 pin connector next to the Blue one @ the bottom of the pic.

Another edit me thinks.

Where is the oil temperature sensorplease? i think its on the bottom face of the main block with a little orange grommit around it with a possible 17mm nut. I need to put a juction in so i can connect up a oil pressure gauge. Thanks.
