    Hey all! Please let me know where you have gotten power for dual electric fans that is switched by the ignition. I will also have a separate switch but I don't want the surprise of a dead battery because I left the fans on after turning off the truck. TIA.

    Just run the fans off the temp switch with constant 12V power to the relays.

    Many automakers do this, (including GM) in your case with your fuse panel, that's probably the simplest way to do it. Even "better" if you use the fan switch mounted in the radiator, since that will cool faster than a block mounted switch.
