I misunderstood your post at first. Thought you meant the rear inverter.
Honestly, it is super easy to add a 12V outlet. Just run a single, positive wire from the battery...through the passenger side firewall...and then down to the floor and either pull it under the carpet and up to a hole you add to the lower center console...or wherever.
If you are bound and determined to use the existing wires that power the 2nd dashboard...you can also do that without too much fuss...depending on how totally buried you want the wire to be. Removing the center console is just the hassle of screws, plastic clips, etc....drilling or cutting out a hole for a standard 12V outlet, etc.
Personally, I would just add one instead of relocate...which could also keep it active when the truck is off. That pretty useful for many things (like letting a dead phone charge while you wander around Costco...

etc). If you are plugged into the stock outlets, they aren’t live with the truck off...
