Brake issues resolved....but.....

I'm working on "upgrading" the wiring on my brand new camper that has not even been on a single trip yet! It came from the factory with 14ga wire in the pigtail to a J-box, 12 gauge from the J-box back to the left brakes and 16ga from the left brake to the right brakes. Wire nuts in the J-box and IDC connectors to tie to the brake magnets. Total disaster waiting to happen when you also take into account they routed the 16 ga wires over top of the gas line and left NO slack in them for suspension movement! When I got home from the dealer (150 miles of towing) the insulation had already worn half off the wires! I am replacing ALL wire from the main J-box back to another J-Box 4' behind it with 10/2 ga wire. Inside the second J-box will be a 8 position terminal strip where I will attach 4 10/2 wires one to each magnet. I will make small coils at each brake to allow for suspension movement.
