Hey just putting a air to water intercooler on and I want the water pump it comes with to work when the truck is on and turn off when it's off. How should I wire it up?

Wire it up to a relay that energises when Ign is "on".
Wiper motor is a good spot or any of the Ign On fuses in the Fuse Box

ok thanks but wipers come on accessories I don't want it on accessories, just when the car is running

Really? Thats a tad odd...
(Edit)
Oops my bad... just saw GQ in the title (GU is different)... grab any "Hot on Start or On" feed off the Fuse box to switch the relay.

They do.

I think the op is wanting it to only run while the motor is actually running. Easy to do with a pressure switch and oil pressure.

I was thinking maybe my turbo timer if that works? Or something easy under the bonnet

Be easier to just a wire into the cab and find an ign wire under the dash wouldn't it?

IMHO yep... otherwise a tap into fuel/turbo timer/alt excitation or whatever but fuse box is easy peasy
