I'm looking to make my trailer light plug into an "isolated" power source to charge my camper battery. When I say "isolated" I mean it's "on" when the truck is running and "off" when the truck is not running. Currently the trailer outlet is always "on", regardless of whether the truck is running or not. Is there an easy way to change this?
I was going to follow the steps in this thread http://www.expeditionportal.com/forum/threads/77503-How-to-make-a-cheap-isolated-dual-battery-setup-for-50 , but can't find an available fuse in either of my fuse boxes that is only hot when truck is on.
Any ideas?
