For installing a brake controller on your 2003 Ford you should be able to use a Tekonsha Plug-In Wiring Adapter # 3035-P to plug into the port under your dash and then plug into the back of your brake controller if it is a Tekonsha brake controller.

If you do not have a Tekonsha controller you could cut off the brake controller connector and wire it by function to the wiring harness from the back of the controller. The white wire will be the ground, the blue wire is the brake output circuit, the red is the stoplight circuit and the black is for a 12 volt power source. Most likely you would be able to wire by color as these colors are the standard colors most brake controller manufacturers use.

I attached a video on the # 3035-P being installed onto a similar vehicle as yours. The vehicle might be different, but the process will be the same.
