The blue brake wire should not always be hot; what that means is you likely have a short somewhere that you will need to find. To do this and look for wires that may be pinched or otherwise damaged and fix as necessary or replace it with 10 gauge wire # 10-1-1.

I have also added links to help articles on brake controllers and troubleshooting brake controllers which I highly recommend checking out. I have also added a help article on trailer wiring which you may find useful.
