I am buying a new 2011 Ultra Classic Limited. The sale includes the trailer hitch and wiring harness. I think I'm buying the Kuryakyn set-up. The dealer will not install the hitch due to liability issues. I'm wondering if the wiring harness will have directions as to which wires to tap into, etc. The bike is also getting the Run, Brake, Turn module installed. Will this interfere with having the trailer wires hooked up? Anyone having a trailer-I would love to see your rig all hooked up. Thanks.
