Video Transcript for Demco Custom Fit Vehicle Wiring - Fifth Wheel and Gooseneck Wiring - DM8555001 Review

Today we're going to be taking a look at the Demco 5th Wheel or Gooseneck 90 Degree Wiring Harness. This is designed as universal wiring harness, so that way it's able to fit many current model trucks. This unit's going to provide your 7-way blade style connector in the truck bed for hassle free hookup of your 5th wheel or gooseneck trailer, and it's going to retain the use of your factory 7-pole connector at the rear of the vehicle. The connector can be mounted in the truck bed sidewall, tailgate post, or wheel well with the included hardware. It's going to come with 4 self tapping screws. To get the connector installed, it does require a 2" diameter hole to be cut, and then it's got the 4 mount holes located right there on the connector. If your vehicle has a bed liner, the bed liner will need to be notched, or you could use a longer set of screws and mount directly into the bed liner or body panel.

If you're working with a spray in bed liner, then you don't have to worry about anything at all, you can just screw it in since that bed liner is sprayed in and sits right on top of the body panel, so no worry there. The harness itself is going to measure 7' long, it's got the nice, insulated wiring design, it's going to easily reach from the rear bumper to the bed. It also includes nylon ties to secure the wiring harness up and out of the way. This unit's designed to plug directly into the factory wiring, no cutting or splicing, you can see how it's split right here, so really nice design, very easy to do, and then you got 7' of wiring, and then this is going to be the portion, again it has the 90 degree design that goes up and to the truck bed. Then, through the 2" hole, you'd fit this in, plug the 2 components together, and then get it mounted into the truck bed with the included hardware, and then you're going to have full access oto your new connector in the bed of your truck. The unit's also going to offer enhanced weatherproofing with corrosion resistant terminals and rubber coated copper wiring. The lid has a really nice design, on the inside it's got a rubber coating on it, like a rubber gasket, so that's really going to help keep moisture out from the connection points when the plug's not secured or not installed.

Nice little finger tab there so you can easily get that opened up and make your connection as necessary. It's going to be constructed of very durable ABS plastic. I do want to mention that on some vehicles you may need to add a fuse or relay to complete all the functions going to the 7-way, and those items are not included. That's going to do it for today's look at the Demco 5th Wheel or Gooseneck 90 Degree Wiring Harness that measures 7' long.

  • Troubleshooting 5th Wheel Wiring Harness and Trailer Brake System Error on 2017 Chevy Silverado 1500
    It sounds like a connection issue. I recommend removing the connections, checking for even the slightest bend in pins, and adding dielectric grease # 11755 to keep moisture and debris out. I recommend doing this at all 3 connection points of your # DM8555001 harness and then also adding that grease to the 7-way under the cover on both units. This is the first I've heard of this issue with a 2017 model and also the first I've heard of the issue tied to installing a 5th wheel or gooseneck...
