I havent yet...mine has been more about rear protection for Rock crawling.
But....I will wire mine via the rear tail light harness on Drivers side...
...and keep plug & wires for trailer in wheel jack compartment.
( Kudos to Tom for that good idea IIRC)
Then just run them out through bottom seal of back door.. when required.
FYI....Thats not my VX...just a clearer pic than I have of my hitch.
I believe U-Haul fits the Curt and will do the wiring...
....not sure how much though.
Cheers
