Hey Dave, thanks for reaching out. The two relays that come with the Curt # C55242 are for the trailer tow backup lamp and the trailer tow battery charge. The two included fuses are for the trailer tow electric brake and battery charge. You will need to consult your owners manual for fuse and relay locations but I recommend removing the current fuses and replacing them with the new ones that came with your wiring kit. That should allow everything to work normally. If not, something else is wrong.

Hey Dave, did replacing the fuses with the ones from your wiring kit help get your electric brakes working? I'm curious to know how it turned out, as it might help others facing a similar issue.
