When installing the Hopkins Trailer Breakaway Kit # 20011, the black, red and blue wire are attached with the following procedure.

The black wire is connected to the black wire in the battery box on the trailer. The red wire is hooked to the positive post (by itself) of the battery on the trailer and the blue wire is spliced to the blue wire from the breakaway switch.

I have attached a FAQ article covering breakaway kit installations as well as a brief installation video.

I can help you further if you can let me know what else you have hooked up - it sounds as if you may have some breakaway components already installed.
