I am getting ready to install my B&W Turnover and Prodigy Brake Controller. For the time being, I will be only pulling a gooseneck for equipment transport. What/where is the best way to install the light/brake hookup plug inside the bed? Also, any tips on where to source these parts or should I just have them install it when they do my hitch? When will the dealers start doing this as part of the "Towing Pkg. "? Come on, DC. Use your noggin!!!
