The USB/ACC is one fuse. I have connected strobe lights and other accessories to that circuit. This circuit is turned off by the computer after shutting down. Worst-case you could wire a 12 V relay to the jack and have the relay switch connect to the battery via a fuse sized like 10A depending on current requirement of the heaters. This way you can switch higher current and still have computer turn off power, so you don't get a flat battery.
In my case regarding ground clearances, I just made my own skid plates under bike and improved grill with a metal grill. I ride off road at times and on dirt/gravel roads, sometimes the grill/skid plate meets up with the ground especially when center of road is higher than the 2 tracks. But I have metal fighting gravel and metal wins!
