So replacing the wiring to the brakes. Previous owner ran Romex stranded 14/2 back to wheels where he spliced and joined the driver’s brake magnet as well as the wiring that goes to the passenger side brake all twisted on a wire nut and taped. Question is there a better way and since the brake magnet wires are both red I guess it doesn’t make a difference whether the black or white attach to it? Thanks
Many brakes do have wire nuts and tape. It normally doesn't matter which wire is which to activate the magnets. I try to go with the same wire on each wheel for either black or white. For instance, if the front brake wire is white, then I go with the back one for black.
Very surprised to hear that! Not saying you are wrong, just surprised a manufacturer would use wire nuts on something as important as brakes. Wire nuts loosen up in houses and loose the connection sometimes. A trailer bouncing down the road? Wow, that just totally surprises me.
If it were mine it would a soldered connections with heat shrink tubing. Last think I want is a brake no working or worse, one side working.
If you want something removable there are not a lot of good watertight automotive connector available now that I am sure could be used safely.
Some of the wire nuts were also crimp nuts, so they were more secure than just plain twist nuts. Almost all were taped with electrical tape. There was another connection of twisting wires together and turning each end back to the wire end, then tape tape tape... some were soldered but in much older trailers.
