How do you ground a brake controller?
Brake controllers require a fairly substantial ground which can be achieved by connecting the controller ground to the negative battery terminal. In some situations a chassis ground is fine but if you are running wires through the firewall anyway might as well go for the best ground location available.
What color wire is the electric brake?
The blue wires carries the brake output from the controller, the white wire is the ground, the black wire supplies 12 Volt power, and the red wire is tied into the vehicle brake wiring. If the wiring adapter you have is an aftermarket harness, it should wire up color for color.

Can trailer brakes be wired backwards?
Expert Reply: Trailer electric brake magnets are non-polarized. When installing an electric brake assembly, like the Electric Trailer Brake Assembly, Left Hand # AKEBRK-35L, either wire can be used for the brake signal and the ground wire, it will not matter which wire is used for which.
Is there a positive and negative on electric brakes?
They require positive 12-volts and negative 12-volts (ground connection) in order to become activated. The magnets themselves do not have polarity, but each must have a ground wire and a hot wire in order to complete the circuit powered by the brake controller. That’s why they typically have two wires the same color.
