You can tap into the blower circuit.

When you see fog lights on in good weather beware. Low performance driver ahead.

How bout those nitwits too scared to drive without headlights in the daytime, and the nitwits that need headlights for a little rain

Re: Hot Wired

Any 12V switched circuit is going to be engaged anytime the key is in the run position. When the key is turned to start to crank the engine, that switched circuit is typically disconnected momentarily.

What exactly are you trying to accomplish?
