When installing the # FACC12SA-BL the two brown wires do not have a pre-determined positive/negative so you can connect either one to either of the furnace wires and it will function properly. If you're going to run the furnace you will need to set the dipswitch on the AC unit; we don't have a video of this process on our website yet but Furrion does have one of this process on theirs that you can check out titled "How to Set a Furrion Chill Dipswitch".
