Usually when trailer wiring causes fuses to blow it is because there is a short somewhere on the trailer wiring. Before you replace anymore wiring components you need to track down that short and fix it so that you don't have to buy any more converter boxes than needed.

I attached a couple FAQ articles that should help you troubleshoot and find the short.
