When I wired up my stay and play braking system I went ahead and hooked it to the battery and then I went ahead and added a charge wire to keep the battery charged my 2014 freedom elite 7 Pin plug does have a charge line to it
one thing that it’s only hot when the RV engine is running main reason I did this for time reasons if you do have a breakaway you’re breaking up system will still use it but toad battery to stop your toad
