Drains battery

Hello!
My car drains battery when in garage and turned off.
Located the problem, its a circulationpump right behind the cooling fan gets 12v when turned off, as it shouldnt.
Its the pump for cooling turbos i figure.

Im thinking to rewire the 12v for the pump to somewhere where it only gets power when engine is on.
Suggestions from where, and is it even possible?

The pump stays on after you park when the car is hot. I wouldn't do that.

Sound like a relay is stuck open.

I may be having a similar issue, how long should the pump stay on for, and where would a stuck relay be, and how to isolate it?

Mine stays on for a couple of minutes, never timed it. And I'm in Florida where it's hot as crap.
