What a solid product this is. I almost couldn't believe how easy it was to install on my Ram 2500 -- which is probably more Chrysler's responsibility than Curts, but definitely have no fear on that. The plug fit well and it's grip on my cable was excellent. Highly recommended

Fit the factory plug. Self tapping screws had no issue screwing into the hitch tube. Exactly why I needed.



by:

The brake controller works great and you don’t even notice the small dial on the dash!

The plug and bracket are great but the screws it came with were terrible. A quick trip to the hardware store for some bolts and I had it all mounted up and working.

  • Choosing 7-Way Connector for 2025 Ford Bronco Big Bend With Factory Wiring
    Hey Charlie! The Curt Dual Connection Socket # C36GJ and the Hopkins Endurance Multi-Tow # HM75MV both fit your 2025 Bronco so it is a matter of quality and design. The Curt connector costs a little more but I prefer their design and they make a much sturdier connector. Since this is a part you want to hold up over a long period of time it is the best option and the one I recommend. What will you be towing once you add the connector to your Bronco?

  • Trailer Hitch, Wiring, and Brake Controller for 2020 Ford Transit T350 Crew Van
    Hey Kevin! Starting with a hitch I recommend the etrailer Trailer Hitch # e98842. This is a Class III hitch with a 2" receiver and a bolt-on installation. Based on the information you have given me I'm assuming you don't have factory wiring so you you will need the # 22114 (single rear wheel) or # 22116 (dual rear wheel) to add a 7-way. The correct wiring kit depends on if you have a dual rear wheel setup or not. Double check the rear bumper of your van and see if you have a dummy plug....

  • How to Connect 7-Way on 2022 Ford Explorer With Tekonsha Voyager iD
    Hi Andy; if you have the factory brake controller port on your 2022 Ford Explorer I expect it to have factory wiring at the rear. Have you checked to see what your 4-way is connected to? Do you have a connector back there that looks like it would fit the connector pictured below? If the 4-way isn't plugged into a round connector like this I would look to see if it is hanging/connected somewhere at the rear behind the bumper with a dummy plug in it. If you have this connector you can use...

  • Troubleshooting Voltage Only On Running Lights On 2025 Bronco With Curt Dual Connection Socket
    Hey Ron! Do you have the tow package on your 2025 Ford Bronco? If it didn't come with the towing package those circuits probably aren't activated. The other functions on the # C36GJ won't work until you take it to your local dealer for activation.

  • Parts Needed to Add 7-Way to 2008 Ford F-150
    Hey Darin! Do you have any kind of wiring on your 2008 Ford F-150? If you already have a 4-way you can upgrade it to a 7-way using the # ETBC7 you were looking at. If you don't have a 4-way you will also need the # C58044. Plug and play is only available if you have the factory wiring connection at the rear. You would also have a brake controller port up under the dash if you had the wiring for the factory 7-way. This would allow you to use a connector like # C36GJ and then a brake controller...

  • Hitch, Wiring, and Brake Controller for 1997 K3500 Dually
    Hey Brian! For 7-way wiring to go with your Curt # C15325 the best option is the # 20023. This is only a 7-way so you can either use an adapter like # PK12716 or swap out the connector for one that fits a USCAR connection like the Curt Dual Connection Socket # C36GJ. For a brake controller I recommend the Redarc Tow-Pro Liberty # RED52VR. The Liberty is simple, reliable, and won't take up space in the cab of your truck. The main unit installs behind the dash so only the control knob is...

  • Replacement Longer 7-Way Connector for a 2022 Toyota 4Runner w/ Factory Tow Package
    Welcome back Richard! The Curt Dual Connection Socket item # C36GJ isn't going to fix your issues but I have an option that will and you won't need to mess with an extension like item # C86DR. The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package item # C55774 is going to be the best solution. The wiring and this connector are just over 15" long and are going to connect directly to your Highlander's factory tow package wiring. You'll be able to mount the connector in a better...

  • Parts Needed To Add 4-Flat And 7-Way To 2016 Ford F-150 XLT With Factory 4-Flat
    Hello Chad, thanks for reaching out. Sounds like you are on the right track here. The Curt # C56413 is correct for your 2016 Ford F-150 XLT, and you can use the # C36GJ socket to make it into a 7-way/4-flat combo. Those two parts actually cover everything you would need. The # C36GJ socket comes with a bracket and a few self tapping screws. That will allow you to mount the socket in the location of your choosing. Typically the best location will be on the rear bumper to the left (drivers...

    Hey Scott, welcome back! Do you have a USCAR connection on there now with the old factory 7-way? It will look similar to the attached photo. If that is what you have, you can use the Curt Dual Connection Socket w/ Bracket - 7-Way RV Style and 4-Way Flat # C36GJ as a replacement. If you have something else feel free to send me a photo and I'll see what is available.

  • Adding 4-flat/7-Way Combo Plug To 2022 Honda Ridgeline With Factory 7-Way
    Hey George, thanks for reaching out. You have a couple of good options to add a 4-flat connection alongside your factory 7-way on the Ridgeline. The first option is to replace the existing 7-way socket with a combination 7-way/4-flat unit. Since the factory 7-way on your Ridgeline uses a standard USCAR connector, you can simply unplug the original socket and plug in a combo like the Curt Dual Connection Socket # C36GJ. This keeps everything clean and factory-looking and gives you both...

  • How to Add a 7-Way Connector to a 2023 Ford F-150 XLT w/out the Towing Package
    No, we do not James and there isn't going to be a plug in one if you don't have the tow package. If your 2023 Ford F-150 XLT doesn't have the factory tow package that came with the 7-way there's no USCAR connector, pictured below, to plug a custom fit connector to. The 4-way t-connectors like item # C63NR that fit your F-150 plug into a factory port are only included with the models that came with the tow package. Now if you find a USCAR connector behind your bumper you can install the...

  • Parts Needed to Install 7-Way on 2023 Ford F-150
    Hey Eric, what you need is a 4-way to 7-way adapter like the part # 37185 which your 4-way would plug into and give you a 7-way that has all of the taillight functions covered. Now if you have a trailer with brakes you would need to go a different route. You'd need to use the # ETBC7 instead and also a brake controller like the Redarc Tow Pro Liberty # RED52VR. Does your trailer have brakes?

  • Wiring Harness For 2025 Cadillac XT5 With 4-Flat And 7-Way
    Hi Ed! I wasn't sure which hitch you were looking at, but I recommend the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" # e62AR. The matte black finish helps hide it better than glossy options, which I think looks more stock-ish. The wiring will be a little more difficult, but not overly so. There isn't a wiring harness for your '25 Cadillac XT5 that has both the 7-way and 4-flat, but it is possible to get something that does. You will need to start...

  • Replacement 7-Way for Rear of 1999 Ford F-350 and in Bed
    Hey Skip, for a new 7-way and 4-way at the rear of your 1999 Ford F-350 you would want the Hopkins part # HM40975 and then for a kit to install a 7-way in the bed of your truck you'd want the part # 41157. This part number comes with the harness that runs from the rear mounted 7-way all the way up to the bed of the truck. We don't have a harness that would run to the rear of the vehicle for the rear mounted 7-way though. Do you need the harness for the rear 7-way too?

  • Recommended 4-Way Connector for a Silverado w/ the Factory 7-Way
    Hey Mark, thanks for the pictures. The Curt Dual Connection Socket w/ Bracket item # C36GJ isn't going to fit without some modifications. It will plug directly into your Silverado's OEM USCAR wiring system but you'll have to cut about an inch into that bottom trim below your 7-way. Please note that the 4-way and 7-way connectors can not be used at the same time with the Curt item # C36GJ. If you're wanting to use them both you'll need item # HM75MV instead.

  • Trailer Hitch and Wiring With Kick Sensor for 2025 Honda Pilot EX-L
    Hi Jonathan; I can help you out with the hitch and wiring but the foot sensor is not something that we carry. You will have to get it from the dealer or an OEM parts site. Since the sensor can be limited by the hitch, I recommend adding it after the hitch is installed so you can get it in the best position relative to the receiver tube. For a hitch I recommend our own etrailer Trailer Hitch Receiver # e27KR. This is a Class III hitch with a 2" receiver and a bolt on installation. It also...

  • 7-Way Wiring for 2024 Ford F-150 XL
    Hi Jeff; do you have the factory wiring on your 2024 F-150? If so, you can use the Curt Dual Connection Socket w/ Bracket # C36GJ. If you aren't sure, check to see if there is a dummy plug on the bumper with a wiring harness plugged into the back of it. If you don't have any factory wiring you will need the Curt 4-Way Flat Trailer Connector # C58044 along with the # ETBC7 to add a 7-way.

  • Availability of 4-Way for Factory Wiring on 2005 Ford E-250
    Hi Debbie; I'm sorry to say we don't have a 4-way that will connect to the factory wiring. The only option would be to use the Curt T-Connector Vehicle Wiring Harness # C56020 which plugs into the connection points behind the tail lights. Is there a factory 7-way on the E-250? You could use an adapter like # 337TC2074P for a 4-way or if you have a USCAR connection the # C36GJ will give you both a 4-way and 7-way.

  • 7-way Connector For 2012 Silverado 1500 Without Tow Package
    Hi Ronny, great question, and I completely understand wanting to avoid cutting into factory wiring if you don’t have to. On your 2012 Silverado 1500, even without the factory tow package, many trucks still came with a round US Car style connector tucked up under the rear bumper near the spare tire. If your truck has that plug, then a socket like part # C36GJ will plug right in and give you both a 7-way and 4-way connection with no splicing needed, just a clean twist-in install. If you...
