Electrical question

I set up aftermarket radiator fan controller which is working well. There is a wire that requires 12 v power when ignition is on. I couldn't find one so I connected it to the battery, but sometimes fans run too long and kills the battery. Is there a wire in the engine compartment that is live 12 v when ignition is on only that is easy to locate? Or that you can point me in right area to look for it? Thank you.
