Video Transcript for Mighty Cord Custom Fit Vehicle Wiring - Fifth Wheel and Gooseneck Wiring - A10-7007 Review

Today, we're going to take a look at the Mighty Cord seven foot long universal gooseneck wiring harness with the seven way connector. This will provide a seven way blade style connector in your truck bed for a hassle free hookup of a fifth wheel or gooseneck trailer. The connector can be mounted in the truck bed side wall, tailgate post, or even the wheel well. The harness is a seven foot long insulated wiring harness. This will easily reach from the rear bumper to the truck bed. Notice right here, it has a nice 90 degree connector, which when you install the seven way, fits into nice, tight spaces.

This harness will plug into your factory wiring. There's no cutting or splicing. It does require that your truck have the factory tow package, and it will retain the use of the factory seven way connector at the rear of the truck. Basically, all you have to do is, when you install this, it will come with everything shown here on the table. What you do is go to the seven way that's on the rear of your vehicle right now, unplug the harness from the seven way, and this T connector right here, plug this into the seven way at the rear, plug this into the harness that you removed, and then run this all the way up to inside your truck bed. Usually, what you end up doing is drilling a hole in your truck bed or wherever you need it, and then run this up through there.

When you install this into the hole, you just connect it just like that. Very simple connection. That does offer enhanced weather proofing. They use corrosion resistant terminals. A lot of their wiring is all rubber coated to protect it. If you notice on the seven way itself, has a nice spring loaded hinge with a stainless steel spring in it.

It is constructed of a nice, durable ABS plastic. As I mentioned, it comes with the self-tapping mounting screws and some nylon cable ties to take up any slack in the wiring when you install this. Again, the length of this harness is seven foot. That should do it for the review on the Mighty Cord seven foot long universal fifth wheel gooseneck wiring harness with the seven way connector.

Great product! Good thick wiring covered in convoluted wiring wrap. Easy to install, took longer to brainstorm an area to mount and drill a hole in my new pickup than to actually install the product. Connectors are solid with a easy snap into place design identical to factory pigtails. 609398

Do you have a question about this Custom Fit Vehicle Wiring?


  • Fifth Wheel Hitch Weight Compared to Truck Payload Capacity for Safely Towing with 2019 Ram 1500
  • The 2018 Forest River Wildcat 28sgx will not be an issue for you to tow. The payload of your truck is slightly different than the hitch weight of your 5th wheel trailer. The reason for the difference is that the payload is based on the bed itself and the strength distributed over the frame whereas the 5th wheel base rails or factory pucks are directly bolted to the frame and have a much higher weight capacity because they aren't simply dispersed over the sheet metal and are directly mounted...

  • Comparing the Reese Quick Install Base Rail Kit # RP50082-58 to the Custom Kit # 50043-6008
  • The Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP50082-58 is a custom bracket kit for your 2004 Ford F-250 and replaced the Fifth Wheel Trailer Hitch Custom Installation Kit with Brackets and Rails - Ford Super Duty 1999-04 # 50043-6008. I reached out to my tech contact and the brackets of the # RP50082-58 have more access holes and the tabs are slightly different. It also comes with more hardware, so it installs differently around the frame....

  • Recommended 7-Way Splitter for Second 7-Way Connection for Truck Camper
  • We don't have a 7-way splitter like the photo you sent. We instead for applications just like yours recommend using the Mighty Cord 5th Wheel/Gooseneck Wiring Harness w/ 7-Pole Connector - 7' Long # A10-7007 or the 10 foot long # A10-7010. This will allow you have the connection at your bumper as well as a connection in the bed of your truck wherever you choose for a simple connection to your in bed camper. There is no problem with charging your battery for either or both of these...

  • Recommended 5th Wheel Rail Kit for Anderson Ultimate 5th Wheel Hitch on 2018 Ram 1500
  • The Andersen Ultimate Connection 5th Wheel Trailer Hitch System with Adapter - 20,000 lbs # AM3200 will work on your 2018 Ram 1500 with industry standard bed rails. For your bed rails I recommend the Curt Custom Fifth Wheel Installation Kit # C16444-204. This is a custom fit for your truck and is compatible with or without factory air suspension. These brackets will not require drilling into your frame and will allow you to utilize holes already present. You will still need to drill...

  • Will a Curt E16 5th Wheel Hitch Work with Reese Quick-Install Custom Installation Kits
  • Yes, the Curt E16 5th Wheel Trailer Hitch part # C16115 will work with the Reese Quick-Install Custom Installation Kit w/ Base Rails part # RP50142-58. The Reese install kit will give you what is referred to as industry standard above bed base rails which works with most above bed mounted 5th wheel hitches from Reese, Pro Series, Husky, Etc. The Curt E16 is a great starter hitch and when paired with the Reese install kit will give you everything that is required to hit the road. However,...

  • Recommended 5th Wheel Towing Package for a 2000 Ford F-250
  • To determine the maximum trailer weight you can tow with your 2000 Ford F-250 you will need to gather both the Gross Combined Weight Rating (GCWR) and the Gross Vehicle Weight (GVW) of your truck. This can all be found on the information tag located inside the driver door jamb. If you subtract the Gross Vehicle Weight (GVW) of your truck from the (GCWR) that will give you the maximum Gross Trailer Weight (GTW) you can safely tow. The maximum towing capacity isted for your truck will vary...

  • Best Fifth Wheel Hitch Recommendation for RAM OEM Pucks with 6-1/2 Foot Bed

This combination will utilize your puck system, give you the capacity you desire, and will allow you to stay inside the cab of your truck when making turns even around gas pumps or backing into your campsite.

  • Recommended 5th Wheel Hitch for 2013 Ram 3500 with 6-1/2 Foot Bed
  • On your 2013 Ram 3500 with 6-1/2 foot bed, a sliding hitch is the route to go for even normal driving. Its the little things like maneuvering around the fuel pump that change things and will make it a game changer for you. Since you are looking for something nice yet economical, I recommend the Reese Custom fit rail kit # RP50054-58 and the Reese 5th Wheel Trailer Hitch w/ Square Tube Slider -16,000 lbs # RP30051. You just want to make sure your trailer GVWR doesn't exceed that 16K...

  • Compatibility of B&W Patriot Sliding 5th Wheel Hitch with Chevy Factory Puck System

The Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package - 6-1/2' Bed - 21K # DM6194 will work with almost any other sliding hitch, but they note it won't work with the Patriot slider. The Ford puck adapter will also not work as the puck locations are different between Ford and Chevy/GMC. The Demco adapter # DM6194 will work well for any other sliding hitch...

  • How to Tow a 5th Wheel Trailer Using a 2013 Ford F-150 with 5-1/2 Foot Bed
  • In order to tow a 5th wheel trailer with your 2013 Ford F-150 that has a 5-1/2' bed you are going to need to use a fixed 5th wheel hitch and a rotating pin box. The reason for this is because the amount of turning clearance you have with a 5-1/2' bed is severely limited so you will need to extend the connection point back away from the cab in order to prevent the loft of the trailer from coming in contact. For a fixed 5th wheel hitch, I recommend the Reese 5th Wheel Trailer Hitch part...

  • I am not sure of what the factory tow package plug on your 1988 Ford F-350 looks like so if you send me a photo I may have a different option for you but if it looks like the one in the attached photo then you can use the Mighty Cord 5th Wheel/Gooseneck Wiring Harness part # A10-7007 which will retain the 7-way you have at your bumper and provide you with one to use in your truck bed with a gooseneck or 5th wheel trailer. If you don't have this plug then you can still use the above harness...

  • The only Chevrolet Silverado that came with a 5-1/2' bed in 2008 was the 1500 model. If you have a 2008 Chevrolet Silverado 1500 with the 5-1/2' bed then I do have a custom kit with above bed base rails for you but the Curt Custom Fifth Wheel Installation Kit part # C16418-204 will not work. Instead, I recommend using the Reese Quick-Install Custom Installation Kit part # RP50064-58. This kit is a direct bolt-on fit for the above truck's frame rails and will work with any brand of 5th wheel...

  • Recommended Best Sliding 5th Wheel Hitch for 2018 Ram 3500 Short Bed with Factory Prep Pucks
  • For your 2018 Ram 3500 short bed with OEM prep system, the B&W Companion OEM 5th Wheel Trailer Hitch w/ Slider for Ram # BWRVK3670 is the most popular option. This hitch is made extremely well in the USA and is designed to fit your factory pucks. This hitch has some built in vibration isolators and has 12 inches of travel for turning clearance. If you prefer the automatic sliding function so that you don't need to get in and out of your truck to change between the manual slider locking...

  • When using the Reese 5th Wheel Rail Adapter for Ram OEM 5th Wheel Towing Prep Package - 25,000 lbs # RP30154 you can absolutely use the Reese 5th Wheel Trailer Hitch w/ Round Tube Slider - Dual Jaw - 16,000 lbs # RP30075. This will give you 11 inches of travel to work well with your 2018 Ram 2500 with 6 foot 4 inch box.

  • Troubleshooting Error Message Week After 5th Wheel/Gooseneck Wiring Kit Install
  • It's not common at all to see the type of error message you received after installing the # A10-7007. The install is usually very solid and rarely is there an issue. Since it happened a week later you might check the condition of the wiring and the connectors to make sure everything is still plugged in like it should be and no highway debris damaged the wiring. Also check the original connector for any corrosion on the pins of the connectors as that is a very common problem.

  • Troubleshooting Factory In-Bed 7-Way Gooseneck and 5th Wheel Trailer Connection on 2017 Ram 3500
  • The in bed wiring harness on your OEM 2017 Ram 3500 connects to the same circuit as your rear bumper 7-way. I recommend removing the T-connector from behind your bumper and inspecting the pins for anything bent. The use some dielectric grease like # 11755 to keep moisture and debris out and reconnect it. Do the same behind the plug in the bed and then test for function. If you don't have the 12V power at that point, then you will want to trace the wire to find the short or replace the...

If you don't have the factory pucks then I recommend the Reese Quick-Install Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP50066-58. Valley is no longer in business so their rails are no longer made and manufacturers don't recommend using their brackets with other rails, so I recommend using the...

However, this option will not allow for sufficient turning clearance because you have a short bed truck.
