Helpful Expert Reply:

If you are running a wire from the battery of your vehicle back to the 12 volt power circuit of a 7-way you will need to install a circuit breaker on the circuit like the part # 9510. The advantage a breaker has over a fuse is that it will automatically reset and won't require you to replace anything.
