The internets changed, you can't find information like you used to... Its all comercial now, you can find info about fitting tow bars because that leads to purchasing one or paying for a fitting service or something to hitch to it. I know the idea of reverse the fitting process but i can't find a brand on mine or a fitting guide for one like mine. Its like a U frame fitted from behind the back seats around the wheel well, then the replacement for the bumper reinforcement bar fitted on to that. Theres small metal panels inside the boot bolted through, its like the weights meant to be spread through the whole back end not just the chasis.

Does the wiring need to be removed from the battery end or can you just remove the plug socket/cut and tape at the rear end? And anything else that might help...
