Umm..... A coil of wire around a iron core (electro magnet) does not have polarity.... At least when it comes to tailer brakes...
Only time there may be a problem is if one end of coil is connected to iron body of brake magnet, then I would think wire would be specifically identified as being ground wire....
Also so wire color doesn't really mean a thing.... Wires on magnets on my tandem axle car hauler are green, both of them and wiring from plug back to axle is black and white in red sleeve..
Wire colors are only for people to trace what wire is assigned to where... Electrons do not care what color insulation is on wires....
And its funny that wiring diagrams specify blue wire for brakes (on trailer) and most "brake" wire that comes in bulk is black and white...
