I'm convinced I need disc brakes and have roamed the forum far and wide looking for info. All of the install work looks pretty straight forward except for the wiring from the king pin box to the controller pump which I would like to install in the hyd pump cabinet like cookie did. How do you route the wires from the TV and the breakaway switch? After the wires leave the j-box they go into a no mans land. I'm working on a on a 2011 BH 3185RL.
