VXR Throttle body control

[feef]

I've acquired a throttle body off an Astra VXR, and was wondering if anyone knew what the voltage and/or control signals were that opened and shut it? I'm hoping it's a simple voltage from 0-n volts.

I'm not using it in an Astra, nor for it's original purpose, just need to be able to flap it fully open and almost fully shut.
