As previously mentioned, if you remove the bar, you will need a new rear diffuser, as when the bar is installed, the cut out the required area for the bar to fit through
Other than that, removal will require removal of the rear bumper bar and the rest is pretty straight forward (removing the bolts that secure the bar to the chassis rails)
The wiring looms are plug and play, so will be able to just disconnect them
The only issue you may have is the vehicle is fitted with reverse sensors and when a towbar is fitted, the vehicles computer is programmed to include the towbar (ie sensors don't go off when the bar is installed and the wiring loom is plugged in)
