Curt 6-Pole Square Trailer Wiring Connector Loop - Vehicle and Trailer Ends - C58034

Average Customer Rating:  4.9 out of 5 stars   (22 Customer Reviews)

Use this Curt 6-way wiring connector to attach to your trailer or pop-up camper. The adapter is constructed of molded rubber and the 12" loop has 6-way square vehicle and trailer ends.


it hooked my pickup truck up to my 2018 Arctic Fox 990. All lites and charging system functioned as designed. Happy with the product


I needed a wiring harness to match what an installer used for a rearview camera hookup on my 5th wheel. I was putting a camera on another trailer, and this was the perfect match to what they used previously.


Was easy to change the one end that was male 6 pin into a female 4 pin to fit trailer to car. Thanks.


This product will be used to connect my eight-wire Ham Antenna rotor to the inside control box. Near the bottom of the tower, I will use it as a disconnect from the control and connect to a ground rod when not in use for lightning protection at that point. I will have another connection at the inside control to disconnect when not in use for lightning protection and will connect the line end to ground. Thus, for lightning protection, the rotor will be grounded at the base of the tower and the line will be disconnected from the rotor control and reconnected to a nearby outside ground rod. I use a six-point connector for the motion control wires and a two-point connector for the hot and ground wires going to the rotor.

Working fine no problems

Did exactly what it was supposed to do. Was happy to find that such a harness was actually available. Saved me a lot of rewiring time.


Fast service. The one end was what I needed but the other end did not fit the camper plug. I bought the camper used and I'm not sure how the original wiring was installed? Was looking to convert from a 6 way to a four way so I could pull the camper with a Trike or car.


Made a great junction connection

Still flexible and working well.

Truly satisfied customer. Order arrived very quickly and accurately. Highly recommend ordering from


2 minutes to install in my 2017 Silverado. It took longer to open the box to plug it in.


I needed male/female 6 pin connectors for a protype and this worked perfectly!


Great product, great service., easy to find and purchase.


Product met needs that I couldn't find in any brick and mortar stores. Shipping and handling was expensive. Great communication by seller throughout process.

  • Gauge Wire Used in the Curt 6-Pole Square Trailer Wiring Connector Loop # C58034

  • Six Pole Trailer Connector Vehicle and Trailer Ends for a 1995 Coleman Pop Up Camper
    The Curt 6-Pole square wiring connector loop # C58034 is only available in the 12 inch length. It should work with your 1995 Coleman pup. The Jayco square plug was the one oddball and if you had a Jayco this harness likely would not work properly but for a Coleman it should be fine. We also have # 37995 which is a trailer and vehicle end. The wires on it are 11-3/4 inches long for each side for a total of 23-1/2 inches.

  • 7-Way to 4-Way Adapter for 2012 Ram 1500 Towing Pop Up with 4-Way
    The connector you have in your hand is a standard 4-way connector on your trailer so all you need to convert the 7-way of your truck to this is the part # HM47365 and you'd be set!

  • How to Tow a Jayco Trailer with a 6-Way Square Connector with a Vehicle that has a 7-Way
    Sounds like you have a 7-way connector on your 2009 Pilot and are looking for a way to connect it to your Jayco pop up that has one of their square style 6-way connectors. Since there isn't an exact adapter for what you are trying to do your best option would be to remove the square connector from the trailer and install a # A7WCB in place of it. This will allow your trailer to be towed much easier by other vehicles in the future as well. You will want to verify the functions of the wires...

  • Availability Of A 6-Way Square Male To 6-Way Round Female Adapter
    I have an option for you, but there is not an adapter made to go between your 6-way square female end on your California Side Car and the round 6-way on your trailer. One option would be to use the Curt 6-Pole Square Trailer Wiring Connector Loop # C58034 and cut off the female end and install the Pollak 6-Pole, Round Pin # PK12720. This will require you to use a circuit tester like the # PTW2993 to confirm the functions of your 6-way square connector and match them to the functions of...

  • What Circuit Functions Are Carried on Jayco 6-Square Trailer Wiring
    Jayco trailer wiring in the 6-pole square format as found on part # C58034 includes the basic stop, turn and tail lighting functions carried on a 4-pole connector and adds two more circuits, typically one for trailer brakes and one for 12V auxiliary trailer power. The 4 Way Flat to 6 Way Square adapter # 30104 connects to a vehicle's 4-pole and carries those lighting signals to the Jayco-style output-end connector. The additional circuits for trailer brakes and 12V power are not included. If...

  • Needing a 6-Way to 7-Way Adapter for an RV with a 6-Way Pin to Connect a Race Car Trailer
    I have a couple solutions for you, but the adapter you are looking for doesn't currently exist. The square 6-way style connectors are an older style that really aren't used anymore. Your best bet is to replace the 6-way on your Holiday Rambler with a standard 7-way like # HM40975-11998. To install this, remove the wires from your current 6-way and splice the wires together by function. Use a circuit test like # PTW2993 to test the wires on your Rambler because it's likely the colors won't...

  • 7-Way Wiring Extension for Camper with Jayco Square Connector
    The Curt 6-Pole Square wiring extension # C58034 uses two Jayco style connectors, both a vehicle side and a trailer side connector, so it can serve as an extension. If you want to install a standard RV 7-way plug on your existing trailer wiring so that the trailer directly matches the connector on the Honda you can use plug # A7WCB. Another route is to install a junction box with a built-in 7-way, such as etrailer # e99011. This box mounts on the trailer and accepts the existing trailer...
