The Ford harness is not colored the same as the Prodigy.
Ford says: White ground
Dark Blue Trailer electric brake feed from brake controller (output)

So, double the end of the brown & tape it. It's not used. Otherwise, black to red, white to white, red to light green & blue to dark blue, Prodigy color listed first.
