I am hoping to wire a 12v bilge blower that circulates air from a cooler with ice in the truck bed into my dog's crate for hot days. It would need to run even when i am away from the vehicle (key out / ignition off). I've been reading the wiring diagrams in GM upfitter but its above my tech expertise. Where can I pull 12v that will be hot even when the truck is off?
There is a 12 volt supply on the 7 pin trailer wire harness.
