Why does your trailer lights go out when you hit the brakes on your f 150?
You have a grounding problem at the trailer. The white wire is the ground on trailer wiring. The taillights are brown, the signals and stops are yellow and green. Sometimes the white wire will loose its continuity with the truck, causing the lights to black out. It could also be a wiring issue with the trailer itself, but most likely its the ground giving you feedback and causing the blackout. run a wire from the ground contact on your plug back to a spot on the tongue and secure the end of the wire to the trailer at that point. Do not rely on the contact of the trailer with the ball hitch to establish a ground.

The extra wires left over are for electric trailer brakes, a 12 volt power supply from the tow vehicle and a rarely used back up light or third brake light. The trailer with a four wire plug only uses the white wire for ground, the brown wire for the running lights, the yellow wire for the left signal and brake and the green wire for the right signal and brake.
