Hello from the U.K!
Welcome! Enjoy your new ride. The running boards are too difficult to install. The mounting locations are already there, it's just a matter of removing some existing trim pieces and bolting the running boards on. I watched the dealership install a set and there was nothing to it -- of course, they had it up on a lift and that helped out a lot.
Requirements in the UK and Europe require modifications. This turn signal is required, as well as a yellow/amber turn signal on the rear. Note in his second pic that the back-up light now has an amber bulb and the back-up lights are now moved to below the rear bumper.
