Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the rear threshold, some interior lining, and the tail light assemblies to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 4-way flat connector will be stowed in your rear cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter

A tail light converter is built into this T-connector. This converter is a battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM11140444 Review

Today we're going to be taking a look at the Hopkins Plug-In Simple Vehicle Wiring Harness with a 4-pole flat trailer connector. This product fits certain gears of the Ford Fusion. You can use the vehicle fit guide located at etrailer.com to ensure that this is a fit for your vehicle. It's going to provide a 4-way flat connector at the back of your vehicle. This is going to power your trailer's signal lights. Now this is compatible with 5-pole, 6-pole, and 7-pole adapters.

If you need an adapter they are sold separately. It's going to come with a dust cap for the 4-way flat connector, simply tethers around the plug and then you can bring it over to the connection points. That way you can cover up those terminals whenever your plug's not being used. The black box on the unit which is located right here, this is the included tail light converter. This ensures that your vehicle's wiring matches that of your trailer's.

This power module connects directly to the vehicle battery through the wiring, which is going to avoid overloading your vehicle's electrical system. Now it is designed to connect quickly and easily. You'll need to locate the connection points behind the tail lights and then plug in your connectors. The connector with the green wiring, that's going to to go the passenger's side. The other side with the yellow wiring is going to go to the driver's side. Now these plugs are custom-fit for your vehicle.

They're going to match up perfectly and they're going to snap lock together for a nice tight secure fit. The unit does come with detailed installation instructions to help walk you through that process step-by-step, but after you make those connections you'll need to make a ground connection. Your ground wire is your white wire, has a ring terminal already attached to it. You want to get that grounded to a suitable grounding location with the included grounding screw. Then you'll need to mount the converter box.

You'll notice that here on the box it has a anchor point on each side. That allows you to simply get this mounted to a safe out of the way location using a few of the cable ties provided with the kit. Then you'll need to run the hot lead to the vehicle battery. The hot lead is this red wire that has a butt connector pre-attached to it. This is going to get connected to one end of the bundle of wiring that's provided. The other end of the bundle runs to the vehicle battery, gets connected to one half of the fuse holder here at the butt connector, the other half of the fuse holder has a ring terminal attached to it. That gets connected to the positive post of the battery. The kit does come with your 15-amp fuse, goes directly in the fuse holder and it's got the cap that goes over to keep that safe and protected. Once you have that done you can go ahead and secure any excess or slack in your wiring with the remaining cable ties. Then when the installation's complete the 4-way connector's going to be stowed in the rear cargo area or the trunk of your vehicle. Plenty of wiring here to extend it out the back when you need it and then tuck it away when you don't want to use it or when it's not in use. It is recommended that you use a small amount of terminal grease upon all of your electrical connections like the plugs on the vehicle and the 4-pole connector itself. That grease is going to help prevent corrosion to to the terminals and it is included with the kit. When it comes to the maximum amperage for the stop and turn lights we're looking at three amps per circuit, and for the tail lights we're looking at six amps per circuit. That's going to do it for today's look at the Hopkins Plug-In Simple Vehicle Wiring Harness with the 4-pol flat trailer connector.

  • All Lights Activate When Running Lights Turned On Using Hopkins Harness On a 2013 Ford Fusion
    The issue you are describing with the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM11140444 on your 2013 Ford Fusion sounds like a failed converter box. I recommend you test all of the wires leading into the converter box to make sure there is power on the correct ones when the corresponding signals are applied. If you then apply the running lights then you should only get power on the brown wire leaving the converter box. If you get power on any other wires but the brown running...

  • Towing Capacity and Parts Need to Tow a Trailer with a 2016 Ford Fusion
    The towing capacity of your 2016 Ford Fusion won't change based on the hitch you choose. According to its owner's manual the Fusion can tow 2,000 pounds if it's the 2.0L GTDI model. Otherwise its max is 1,000 pounds unless you have the Hybrid or Energi models which are not rated to tow at all. The hitch I recommend for your Fusion is the Curt # C12091. I like the Curt because they're generally built better than some others and just as reasonably priced. All of our prices on the product...
