If you are not getting any lights on your boat trailer then you most likely have some blown fuses in the tow vehicle's fuse box which is the first thing I recommend you check. If the fuses check out then use a circuit tester and test the pins inside the trailer connector on the tow vehicle. If you don't get power here then you have an issue with the vehicle's trailer wiring circuits but if you do get power here then start probing the wires on the trailer side.

If you get power leading into the trailer side trailer connector but not leaving then you most likely just need to reground the trailer connector. If you do get power leaving here then you will just need to use the circuit tester and work you way back so you can see where the power stops and repair as needed.
