We have a 7-way upgrade kit part # ETBC7L that comes with everything needed to install a 7-way in place of a 4-way and comes with the parts needed to activate the 12 volt charge circuit of the connector as well.

Basically it's the same thing as the # 30717 except comes with a wire that runs to the vehicle battery and a breaker to install inline with this circuit.

Need to know where the blue wire for the trailer goes on the fuse box

The blue wire of the # ETBC7L or the # 30717 would run to the brake output circuit of a brake controller. If you have a brake controller installed in your vehicle this would be the circuit to use for the blue wire of it. Otherwise if you don't have a brake controller you do not need to wire it to anything and it can be left uninstalled. You might just tape it up and out of the way.

The black wire does charge the auxiliary battery for your winch and also the breakaway battery. So if you have a need for either you'd need to connect that circuit.
