Features to know about

Effortless Towing Connections: 7-Way Connector in Truck Bed

Hooking up your 5th-wheel or gooseneck trailer has never been easier. With a 7-way, blade-style connector conveniently mounted in your truck bed, you can quickly connect your trailer without the hassle of reaching underneath your vehicle. This seamless setup saves you time and energy, turning a potentially stressful task into a piece of cake. Ideal for Ford trucks with aluminum beds, this addition makes your towing setup neat and organized.

Keep Your Factory Connections: No Cutting or Splicing Required

Say goodbye to the headaches of altering your truck’s electrical system. The Curt Custom Wiring Harness plugs directly into the factory wiring of your vehicle, retaining the original 7-pole trailer connector at the rear of your truck. This ensures that you maintain all the existing functionalities and eliminates the need for messy, time-consuming wiring modifications, preserving your vehicle for future resale value.

Combat Corrosion in Aluminum Beds: Rubber Well Nuts Included

Worried about galvanic corrosion when installing accessories in your aluminum truck bed? The provided rubber well nuts separate the included stainless steel bolts from your aluminum bed, helping to prevent corrosive damage. This feature ensures long-term durability and peace of mind, so your investment remains protected against the elements.

Reach Every Corner: 10 Feet Long Insulated Wiring Harness

With 10 feet of insulated wiring harness, this setup reaches from your rear bumper all the way to the truck bed, accommodating even longer truck models. This ample length provides flexibility in mounting locations, whether you choose the sidewall, tailgate post, or wheel well of your truck bed. It’s designed to give you the length you need for a stress-free install, ensuring a perfect fit every time.

Comprehensive Installation Kit: Everything You Need in One Package

Installing your wiring harness shouldn’t require a trip to the hardware store. That's why this kit includes everything you need for installation: zip-ties, four stainless steel bolts, and four rubber well nuts. With these components on hand, mounting your connection point becomes a straightforward project you can complete at your convenience.

No issues with harness. Installer could have used better screws because the bed is aluminum.

Delivery was fast. Part was perfect - excellent job.

Plug and play was perfect. Has not given issues over the first year of service.

I added this to the left front of my bed for a slide in truck camper. It connected into the factory 7 pole connector in the rear of the bed. Fits well appears to be well made and installation was easy after getting the courage to cut a 2 1/8 inch hole in my bed.

Easy to install took my time and probably measured more than I had to I was nervous cutting a hole in a brand new truck!

Excellent product with clear instructions. Fit my 2019 Ford FX4 with a towing package like a glove. Be sure to follow instructions for aluminum beds and interior sidewalls.

  • Recommended 5th Wheel Hitch For A 2022 Ford F-250 With A Tri-Fold Tonneau Cover
    Hello David. I can definitely help point you in the right direction. Does your 2022 F250 have the OEM 5th wheel prep package in the bed? Post in the comments below and let me know because that will be a major deciding factor in selecting a hitch. If you do have the OEM prep package, you will have a lot of options for a hitch that will fit in the 18" deep bed with a tri-fold tonneau on top. My recommendation is the B&W Companion OEM 5th-Wheel Hitch for Ford Super Duty Prep Package # BWRVK3300....

  • Will Curt T-Connector Vehicle Wiring Harness Fit 2025 Ford F-350
    Hi Robert; are you looking for a replacement 7-way or are you trying to add 5th wheel/gooseneck wiring? The Curt # C69CR you were looking at is designed to replace a 7-way at your rear bumper. If you are trying to add a 7-way to your truck bed for 5th wheel/gooseneck towing you need the # C57010 instead.

  • How to Install a 7-Way Inside the Bed of a 2019 Ford F-250
    Hey Jeff. To run a 7-way connector to the front of your bed and keep the one on your bumper, you'll need the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector for Aluminum Beds item # C57010. The Harness plugs directly into the factory wiring of your Ford. It'll be behind the factory 7-way. I've linked an installation video below so you can see how to get the Curt item # C57010 setup. What kind of camper do you have?

  • Recommended 5th Wheel Rails for a 2024 Ford F-250 w/out the Puck System
    Hey William. To add a set of 5th wheel rails to your 2024 Ford F-250, I recommend the B&W Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches item # BWRVK2402. These custom fit brackets mount to existing holes in your truck's frame. They fit both the 6-1/2' and 8' bed models without the factory puck system. The rails will work with B&W, Curt, Demco, Reese, Anderson and PullRite 5th wheel hitches and accessories. To make towing with a 5th wheel easier, I recommend adding...

  • Recommended After-Market Puck System for a 2024 Ford F-250
    No, it does not Tim but I have one that does. Instead you will want the Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches item # RP67KR. This is an identical set up to not only the one you were looking at but also the factory puck system that comes with the Ford trucks. The Reese Under-Bed Gooseneck Trailer Hitch item # RP39FR, you were looking at, only fits the 2017 - 2022 Ford F-250, 350, and 450. To make towing with a 5th wheel easier, I recommend...

  • 2022 Ford F-350 Plug-In Wiring Harness for In-Bed Truck Camper
    Hey Tom, thanks for reaching out! We can definitely get you up and running with the wiring on your camper - you'll just have to choose which option best suits you: - Standard 7-Way Connector # C57010 - Magnetic 7-Way Wiring Kits # 319-S7-09 and # 319-S7-10 I prefer the magnetic setup just because it will still disconnect if you happen to forget to uncouple the wiring prior to pulling away from the camper. If you aren't concerned about it then feel free to go the standard 7-Way route!

  • Recommended 4" Offset Ball for a 2018 Ford F-250 w/ a B&W Gooseneck Hitch
    Yes, they do Josh. Since your 2018 Ford F-250 has the B&W Turnoverball item # BWGNRK1116, you'll want the 4" Offset Ball for B&W Turnoverball Gooseneck Trailer Hitches item # BWGNXA4085. We've talked to B&W before about using the 4" offset ball item # BWGNXA4085 backwards and they've said not to do it. Their answer has been that the offset ball is only designed to be used as an extension to give you 4" of additional clearance and not the other way around. The holes in the center of the...

This is just the frame brackets for the Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches item # RP50074-58. What brand of 5th wheel rails do you have?

  • How to Mount a Demco Autoslide 5th Wheel Hitch in a 2025 Ford F-250 w/out the Puck System
    Hey Cody. Congrats on your new truck. Demco does not make an underbed system for your truck. The only underbed system available for a 2025 Ford F-250 without the OEM prep package are gooseneck hitches like the B&W item # BW73FR. There's no way to mount your Demco Autoslide item # DM8550022 to this set up. What you're going to need are a set of 5th wheel rails item # BWRVK2402 and new side plates item # DM6003.

  • Troubleshooting Truck Bed 7-Way Not Functioning
    Hey Robbie, are you absolutely sure all of the connectors of the # C57010 are fully seated and making contact? There's really no other reason two of these wouldn't work for you. If the 7-way at the rear of the truck still works when this is installed it's got to be the connection of the truck bed 7-way to it's harness.

To use a Pull-Rite SuperGlide Hitch like item # PUL93RR with the Ford factory puck system, you'll need the Reese Elite Series Underbed Rail Adapter for Standard 5th Wheel Trailer Hitches item # RP30156. This adapter will drop right down into the pucks and provide you with a base equivalent to industry standard 5th wheel rails. To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C57010. This harness puts a 7-way...
