The trailer brake wiring connection is part of a complete trailer lighting and breaking system. The harness plugs into an adaptor near the spare tire behind the license plate.

Not exactly the answer to the question...
The brake controller harness plugs into a grey colored connector located under the large removable plastic cover just below your steering column. It is to the right side of the column.
When one is using a trailer on their car, an electric brake controller measures the car's braking speed and adjusts the electric braking power of the trailer to correspond. This helps avoid collision between trailer and car.
There is a connection issue between the trailer brake controller and the trailer.
should be down by steering column.check owners manual.

This site will show you exactly where the connection is and what you will need. http://www.etrailer.com/faq-cbc.aspx
if it has the plug in the back of the truck for trailer brakes then it is under your dash. it should be a female plug. about in the middle of the dash(more twards the left) you can get a plug from ford that plugs right in and it will have leads off of it to wire right to your brake controller. makes it super easy
Most trailer brake controllers require 3 or 4 "inputs" and have 1 output. Ground, any point on the vehicle metal frame. Power, any fused connection that provides power when the key is on. some controllers don't use a power connection. You'll need to refer to the owners manual that came with the controller. Brake light, a signal from the brakes indicating that the brake pedal has been depressed. The output goes to the trailer plug pin that controls your trailer brakes.
If you want trailer brakes you need a brake controller.
I don't believe there is one. I had to have mine wired in.
A coupler is the connection point mounted on the trailer which connects the trailer to the vehicle.
Electric brake controllers (for trailer towing) can be added to any vehicle however, I have not ever wired one so I can't advise you on that. There should be instructions with the controller, unless it's used, in which case I would do a google search for info on that.
i think that in some states it is illegal not to have one, but im pretty sure that if your car's brakes are good enough, you won't need one. but, it is terrible for your car's brakes if you dont have one and you are hauling a trailor. If the trailer has electric brakes - YES. Otherwise, no.
