I know the first gen Ridgelines have rear differential breathers that went up to the height of the door handles. I believe the never gen Ridgeline/Pilot/Passport have the same feature. Our air intakes are located at the top of the hood. As far as electronics, I’m not sure, but I did a good 26 inch river crossing in my passport with 3 inches of total lift.
here’s my Instagram video clip and below is a pic of the diff breather tube.
