You already have the battery charge line in your 7 pin plug, and it's already fused on that end. Add a 20A fuse to the other end, right at the battery. There are a number of "special chargers" out there that you can buy that will only add to your cost and give no additional features as far as charging, or keeping the toad battery charged. One thing to check, however, is put a voltmeter on your 7 pin charge (bat) line and see if it's hot all the time, or only when your coach key is on. Most are hot only when the key is on, but not all. If yours is hot all the time, you'll want to pull the 7 pin plug if you leave the toad hooked up for an overnight stop. Keeps the toad from draining the coach batteries when your coach engine generator is not turning.
