By "hard-wired", I'm assuming that your Furrion refer is DC. If this is the case, as
@rglow314 mentions, you will need to provision an AC circuit and outlet for the residential refer.
I'm uncertain what all is currently on the AC circuit in that slide now. You might be able to use it for the new outlet you need. If not, you will need to run another circuit for it from the coach AC breaker panel. Look under the slide to see how all the wiring is run now and what type of wire is used (SOW) and mirror that method for your new circuit if needed.
