: Where do you wire the Black Magic 150 fan to make it turn off with the key?

: Right now I have it wired to the fuse box under the hood (that's always hot) with the fan's main power source. I admit, I really love seeing the reactions of people walking by when the fan turns on and nobody is in the truck! :) But as the temp outside starts to warm, I'm a little worried the fan will drain my battery and won't start the truck. Anybody have any experience with this?

  Shane,

  What you can do is to cut your current power feed line to the fan,
and install a relay in-line. As the switching source for the relay,
tap into any wire or location which is hot when the ignition is on.
