Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM11140755 Review

Today we're going to be taking a look at the Hopkins plug-in simple vehicle wiring harness with a 4 pull flat trailer connector. This product fits certain years of Ford F250 and F350. You can use the vehicle fit guide located at etrailer.com to see if this is a fit for your vehicle. It's going to provide a 4 way flat connector at the back of the vehicle to power your trailers signal lights. This is compatible with 5 pull, 6 pull, and 7 pull adaptor. Adapters are sold separately.

It comes with the dust cap for the 4 way flat connector. That way you can cover up the connection points when your plug is not being used. Now, this unit's designed to connect quickly and easily. All you got to do is, locate the connection point behind the rear bumper and plug in your connector right here. Very quick and easy to do. Custom fit for your vehicle, so it's going to match up perfectly with the plug on the vehicle.

Then you'll need to make a ground connection, that's the white wire with the ring terminal already attached to it. You want to get that grounded to a nice clean metal surface with the included grounding screw. Then you can use the zip-ties that are provided with the kit to secure any excess or slack in your wiring. Now, once your installation is complete, the 4 way connectors are going to be stored beneath the vehicle near the trailer hitch. We do recommend using a mounting bracket to keep the connectors secure and easily accessible. Mounting brackets are sold separately.

It's also recommended that you use a small amount of terminal grease on all of your electrical connections. Like the plugs on the vehicle and the 4 pull connector itself to help prevent corrosion. The terminal grease is included with the kit. That's going to do it for today's look at the Hopkins plug-in simple vehicle wiring harness with a 4 pull flat trailer connector.

  • Recommended 5th Wheel Wiring Harness for 2022 F-350 Diesel
    I reached out to Curt and found that the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 has the same connectors as the # C57010 which is confirmed to fit the 2022 Ford F-350 with factory 7-way. This means that the # C56070 will also fit if you have a factory 7-way. However, you would want to use the # C57008 instead since it comes with the rubber well nuts that separate the stainless steel bolts from your aluminum truck bed to help prevent galvanic corrosion. Since it sounds like...

    Hey Tim, the Reese Quick-Install Custom Outboard Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # RP56001-53 you mention is actually not going to work with your 2022 Ford F-250. Instead, you're going to have to use the Demco Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches # DM8552031-71 which will work with both your F-250 and your Reese 5th Wheel Trailer Hitch w/ Square Tube Slider # RP30051.

  • Wiring Recommendation to Fit with Lance 6-Way Connector on 2016 Ford F-250
    If your 2016 Ford F-250 doesn't already have a factory trailer connector then the Hopkins # HM11140755 is what you need. This plugs into a factory port underneath your truck and then you'll cut off the 4-Way and splice it into that Lance 6-Way connector. The wires are labeled so you just need to match the functions. If you do have the factory trailer connector then the Pollak # PK11893-11932 is a great alternative because it tees in behind your factory 7-Way and gives you all of the functions...

  • Troubleshooting 4-Pole Running Light Circuit on 2015 Ford F-250 Super Duty
    I suspect the issue with the running light circuit on your 4-pole trailer wiring setup is either related to internal damage or corrosion of the connector. Since your truck headlights still work we know that circuit is active. Unless you can find a blown fuse for 'parking lights' or 'running/tail lights' in the power box I would suspect the connector, especially since it is permanently located outside the truck where it is exposed to the elements. Corrosion can build up inside a connector...

  • Parts Needed to Install Brake Controller in 2020 Ford F-350 without Trailer Wiring
    You will need to start with a 4-way (if you do not have one). For that you would want the # HM11140755.
