A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

...Hi, etrailer recommends to using Deka 10-2 gauge wire for running electric brakes to a tandem axle trailer. If this is the case, why does 7-way harnesses with molded plugs only have 12 gauge wiring...

...the 7-way connector. We then run a jumper wire from the electric brake power wire to the right side brake assemblies (see photo). I recommend using 12-gauge wire, # 12-1-1, for the jumper wire...

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…
