You just sent 12+ DC volts directly to your trailer braking system.
There is a reason why a brake controller is required. One thought comes
to my mind is that the controller regulates the voltage to the trailer
brake solenoids so that the right amount of voltage will actuate the
right amount of braking to prevent wheel lockups. Its an original
concept that has work for many years.
I think I would go down to your local Ford Dealer and order the proper
harness.
