What would cause my tail lights to go out completely after plugging my standard trailer harness into the u-haul trailer harness by accident on a 1996 Ford Explorer?
It sounds like your power wire matched up with a ground wire on the trailer or vise versa so replace the blown fuse for the marker lights and everything should be good. Check fuses in cab and in engine compartment.

How to fix boat trailer lights Both blink while left turn signal is on Tail lights work ok when head lights are on and when right turn signal is on?
Check ground circuit Check bulbs they are duble filamented one may be burned out Seems to me there is a wire crossed at the harness. I think the vehicle left turn signal wire is hooked up to the trailer tail lights wire. Usually there are four wires at the trailer harness, yellow, green, white, and brown, The brown wire is usually the tail lights and side marker lights, the white wire is ground, the yellow and green go to the left and right signal lights.

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.
