if using the stock holden 2-pin sensor, it doesn't matter, neither of them are grounded to the body of the sensor. connect them either way.

Depends what you're after.
TPS has 3 pins, centre to one bottom is TPS on. Centre to TOP is 3/4 TPS on.

most after market TPS would use a variable resistor type or potentiometer.
An automatic trans car has an extra connector dangling off the TPS sensor case. I would use that one instead as its a Variable resistor/Potentiometer type.

The POT will vary it's resistance from close throttle to WOT. I can't recall which way around they are but again, just use centre pin to top, or centre pin to bottom. The ECU will show you TPS as full open or full closed. switch one wire from top to bottom if its backwards when you press throttle.
