The wiring from the Furrion wall controller to the roof unit MAY (your system may be different) include extra conductors depending on what Grand Design had available at the time they built your unit. In my case, I had extra conductors so I went ahead with this relocation method. Here's what I did.
disclaimer: do this at your own risk. It's not hard if you're used to working with small gauge wiring.
Step 1: Find your wire bundle from the wall controller. It will be spliced to the red, blue, green, and purple wires going to the rooftop unit control module. Are there extra conductors? If so, you're in luck.
Step 2: Remove the wall unit. It comes off with a quarter turn lefty loosey. I also removed the backing plate as seen here since I needed to enlarge the factory hole in the wall slightly to get all those big blocky splice connectors out.
Step 3: Isolate your spare conductors and strip away any outer insulating jacket to free up some slack.
Step 4: Cut off the existing temp sensor with enough slack on both ends of your cut to make some splices. No turning back now! Strip and splice the wires together. Splice each conductor individually, then optionally shrink wrap the whole works together for added strength. I used heat shrink solder connectors you'll see in subsequent photos. They work great.
Step 5: Splice your temp sensor leads to the remote ends of your spare conductors. I used heat shrink solder splice connectors but butt connectors would probably work too. The conductors in the wire bundle are not braided though and I don't like butt splicing solid conductors when solder is a thing that exists.
