I hate to ask this, because I suspect I know the answer. Is it possible to connect a hitch wiring harness to my Ultra Limited even though I have the Run, Brake, Turn wiring done? If it is possible to connect this, is it safe for the charging system? Would I be better off to just remove the run, brake, turn when I connect the hitch wiring? I think the RBT is a Harley harness. It was installed prior to delivery. The Hitch wiring harness is a Khrome Werks part. Any help is appreciated. I don't want to over load the charging system just to have two extra lights out back.
