I was finally able to remove the CRV fuse using a long forceps I use to get hooks out of northerns. It did turn off the display when the car key is on accessory. The bad news is that it also cut power to the outlet that I used to plug in the Blue Ox Patriot. Put the fuse back in.
When I plugged the Patriot in it said the car battery was low. I was quite confused. Called Blue Ox customer service. They said that the Patriot has a battery inside. When it's discharged it reads low car battery. She said to plug it in and drive the car for a few hours to charge it. There is nothing about a battery or need to charge it in the manual!, The Patriot still needs the car battery to trickle charge it when in use.
Long story short, I need a harness from coach to car battery as suggested by several of you. Hope this helps other CRV owners out there.
