I believe the problem is the connection of the switch on your breakaway. You said you went from blue brake output on the trailer to the blue wire of the switch and then on the other side of the switch you went to a black wire. You should have went to the blue wire of the battery box. The black wire of the battery box goes to the 12 volt power of the 7-way which is typically red.

Check out the diagram I attached for more info as well.
