It sounds like something is causing a short circuit in the wiring of the Curt harness you mentioned in your question.
I recommend checking all of the connections the harness is making to your vehicle to see if there is anything out of place that may be causing a short. Look for damaged or frayed wires, any wires that are touching bare metal or two wires that are touching each other, wires attached to the wrong location or any corrosion along the wiring. Any of these things can potentially cause a short that is leading to the blown fuses.
Lastly, check to make sure that there are not any cut or exposed sections of the power wire between the fuse and converter box that would cause the wire to overdraw and blow the fuse.
I have also attached an article on troubleshooting wiring installations that you may find helpful. If you are not able to find the cause of the blown fuses, please let me know and I will be happy to look into this further.
