They normally run out just below the grille. Are you saying it does not have the end that plugs into a cord on it?
If it were mine, I'd add a covered 120 male end to it from a RV supply and mount it like a 7 Pin on a shrockworks rear bumper (See that thread install for a pic) Rout it so there is a drip loop near that end and seal it with silicone. Open in, insert female end of heavy duty extension cord and she heats up.
Rule of thumb is you turn off the vehicle and plug it right in. It keeps the water hot. Then you unplug it to start. If you don't when you start it the flash of cooler water over the element jacks it up and may burn it out or at least reduce the life of it. Instructions should say all this.
