BIGRED460....not sure what you mean that "the wiring is there, cut it and pull it down" yea, the wiring is there to the taillights BUT the plug you want installed rather 4 blade or 7 pin has to be installed and placed....I don't think they had to unbolt my box....they did have to take out the spare and replace it later, but I am told it is a rather easy install once you either do one or see one already installed...the Dodge hitch is very nice and fits cleanly up and under the bumper and definitely looks like it came from the factory, also has one of the higher tow ratings...my hitch even came with the black rubber plug with the ram's head on it...just my $.02
