if all your after it hard wire it so its off when the car is off, why not just run add a fuse to any fuse that is off when the car is off, and on when its on?

id also wire a relay to the pump.

you can also put a on/off switch on it so you can turn it off if need be when the car is on and running or key to run for what ever reasons.

look up how to wire fog lights, same deal just a pump instead of fog lights at the end.

Find out the name on of the relay and look up the data sheet.

Or you can mess with it find which pins activate the switch. You'll hear a click when you hook it up right. Hook your switched power source up to that.


Then use a multi meter to see which of the remaining pins is the output.
