Which Wire of Trailer Brake Magnet is Power and Which is Ground
Question:
I have black and white wires coming from the brakes on my trailer, do both wires plug into the EB pin on my connector?

Expert Reply:
So trailer brake magnets are not polarity sensitive which means that either wire can be used as the power or ground circuit. So basically you just would need to pick whichever you wanted to be the power wire and then ground the other and you'll be set. Typically white is ground on trailer wiring and black is 12 volt power.
