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…
That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
Yes, it will work. You'll just need to cut the Lance 6-pin connector out and rewire it into the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector item #e99011. Here are the individual functions of that Lance 6-pin:…
Hey Robert, thanks for reaching out. The Curt Cold Weather 7-Way RV Style Connector #C23RJ uses a combination of 14-gauge and 10-gauge wire. The black 12V power wire and white ground wire are 10 gauge, while the brown, red, blue, green, and yellow…
The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. If you check out the picture I attached you'll see that the functions are all the…
The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
Since wire color codes are NOT universal, we always recommend wiring by function, rather than wire color. If you look at the Trailer Wiring FAQ article I have linked you to, you can see some diagrams showing the proper way to wire a vehicle and…
Hey Mark, thanks for reaching out, and good question. That “16/18 gauge” wording throws a lot of people off. The TowSmart 16 to 18 Gauge, 4 Conductor Wire #TS57QR isn’t all one size. It’s a 4-conductor cable with mixed gauges inside, two wires are 16…
In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
Hey Gary, thanks for reaching out. No, nothing is missing from the #C96GJ kit. Curt uses the term “T-Connector” pretty broadly for a lot of their plug-and-play harnesses, even when they are not a true tee-style splitter like you were expecting. On…
Welcome back Jordan! I have an alternative for you but we do not have any Ram 7k jacks that can be bolted on. Just welded like item #TJD-7000S and pipe mount like item #TJDP-7000S-B options. For a 7,000 lbs capacity square jack that can be bolted on,…
Very helpful/friendly Customer Service. Competitive Pricing. Shipping was Fast.

Trailer Wiring with 7 contact connectors
Hook up confidently with trailer wiring built for 7 contact systems. Options include magnetic connections that help avoid accidental unplugging and corroded, loose blade issues, plus adapters to a typical 7-way when you need to tow another trailer. Choose hardwire or plug-in harnesses and pick straight or coiled cables to match your setup; frequent daily disconnects in dirty, industrial use may call for extra care.
Yes, it can replace an existing 7-way and be hardwired on both vehicle and trailer. Match each wire location carefully and cut wires to the same length for a tidy fit. Check the trailer-side pigtail length to ensure it reaches your tow vehicle. Plan the mounting spot for ground clearance and protection from road debris.
Use an adapter to connect your magnetic 7-way to a typical 7-way blade. Keep one on hand if you might tow someone else's trailer. Verify that all light and brake circuits function after plugging in. Store the caps on both ends when not using the adapter to help keep contacts clean.
Either can work, but pick based on reach and routing. Some kits include a non-coiled straight cable, while others offer coiled options. Check that the cable reaches comfortably without tension, especially with a pin box or long tongue. Avoid excess slack that could drag; consider custom mounting to gain ground clearance if needed.
Yes, a magnetic 7-way can help reduce intermittent connections and corrosion-related issues. Direct flat surface pin to pin contact and watertight sealing help keep connections clean and reliable, even in rain. If you disconnect daily in dusty or muddy sites, keep the magnetic dust caps on and clean the faces as needed. If you see recurring corrosion after storage, inspect the O-rings and ensure the caps were seated fully.
