Hey Henry, thanks for reaching out!
I see you already purchased the Curt T-Connector Vehicle Wiring Harness # C55774 which is a great option, especially if you have the USCAR connector on the back of your 7-Way that allows this to be plug and play.
The only other thing I'd recommend picking up is the No-Drill Mount Bracket # 18136 so you can easily install it on your motorhome.
Let me know what you think of the Curt wiring once you've got it installed!
