usually you take off the bumpers, and then take off the bumper brackets, the tow bar should bold on it the pplace of the bumper brackets and then the bumper will mount as it did before, you may have to cut a slot into it, so it will fit over the tow bar. as for the electricks, are you fitting twin or single? for the lights you'll need to connect into the existing lights at the back of the rear lights, this can be done with scotch locks, but splicing and soldering is a better way of doing the job.
