If you are referring to a trailer, the 7 pin connector is not wired for a third brake light. There are only two brake light wires, one for left and one for right. And since they are also turn signals, you can't just wire a center brake light to one or the other. Neither can you wire it to both using isolation diodes. To do so would cause the center brake light to flash any time you were giving a turn signal. Unless you do not mind the center brake light flashing when you give a turn signal of course.
The only way I can see it work properly would be to run a new wire from your tow vehicle center brake light, thru a connector at the trailer hitch, and a new wire to the back of the trailer for the new light.
