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 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 connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.

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.

Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM11141995 Review

Today we're going to be taking a look at the Hopkins PlugIn Simple Vehicle Wiring Harness with a 4-pole flat trailer connector. This product fits the Dodge Grand Caravan and Chrysler Town & Country beginning with year 2011. 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 your vehicle to power your trailer signal lights. It 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, that way you can cover up the connection points when your plugs not being used. It also includes this tail light converter. This is going to ensure that your vehicle's wiring matches that of your trailers. This power module connects directly to the vehicle battery through the wiring to avoid overloading the vehicle's electrical system. The unit's also designed to connect quickly and easily. It's going to come with really well done detailed installation instructions to walk you through the entire process step-by-step.

That basically what you'll need to do is locate the connection points behind your tail lights. The connector with the green wire, it's going to go to the passenger side. Connector with the yellow wire goes to the driver's side. Now the plugs on this harness are custom fit, so they're going to match up perfectly with the ports on your vehicle. Locate your connection points behind the tail lights, plug in your connectors, and then you'll need to make a ground connection.

Your ground wire is the white wire with a ring terminal attached to it. You want to get that grounded to a nice, clean metal surface with the provided grounding screw. Then you'll want to mount the converter box. You'll notice that there's a mount located on each side, that way you can easily get this secured, out of the way, with the included cable ties. Then you'll need to run the hot lead to the vehicle battery. Your hot lead is this red wire coming out of the box.

It has a butt connector already attached to it. This gets connected to one end of the bundle of wiring. The other end of the bundle runs to the vehicle battery and it connects to one half of the fuse holder. The bundle's going to connect to the butt connector on the fuse holder, the ring terminal side gets connected to the positive post of the vehicle battery. It does come with your 15 amp fuse, goes directly in there, and its got the fuse cap that goes over to keep it safe and protected. Now once you have all that done you can go ahead and secure any excess or slack in the wiring with the included cable ties. Once your installation's complete, the 4-way connector's going to be stowed beneath the vehicle near the trailer hitch. We do recommend using a mounting bracket to keep the connector secure and easily accessible. Mounting brackets are sold separately. Then we also want to recommend that you use a small amount of terminal grease on all of your electrical connections, like the plugs 00:02:45 on the vehicle, and the 4-pole connector itself. The grease is designed to help prevent corrosion to the connection points and the grease packet is included with the kit. Now when it comes to the maximum amperage for the stop and turn lights, we're looking at three amps per circuit. For the tail lights, it's six amps per circuit. That's going to do it for today's look at the Hopkins PlugIn Simple Vehicle Wiring Harness with a 4-pole flat trailer connector.

2015 Dodge Grand Caravan

Ordered this Hopkins trailer wire harness for my 2015 Dodge Grand Caravan as a replacement to the curt harness that I installed 3 years ago. After two years the curt harness stopped working so I thinking that this time the Hopkins harness should last longer because the curt harness used two sided tape to hold the control box in place but did not hold and was banging around a lot were as the Hopkins harness has tabs that I can secure the box with zip ties or screws. I was very happy with ordering from etrailer. It was easy to find what I needed and order through the site. Plus fast shipping and email communicaton that my part was shipped the same day I placed my order. 561563

I am totally pleased with my new hitch and wiring harness. It has been just about a year since I ordered and installed it myself. Great quality. Great customer service , and the product price was very reasonably priced. To me, this is a top notch company with top notch employees that provide top notch products. It was a pleasure to do business with them. Oh yes, I almost forgot to mention the great “how-to” videos on their products. These are why I felt confident enough to install it myself. One more thing. I checked around with other sources, both locally and on line before deciding (this is probably the fourth hitch that I have had over the years), but the reviews for this company and their products were more than I could resist. And the great rewiews were totally accurate. - And, they shipped promptly. My hitch fit great and looks great too - that is to say, one has to really look to even see it. ?????????? 5 thumbs up from this satisfied customer! 577241

The wiring harness worked just fine as advertised. It took about 2 1/2 hours to install but that is because I am overly meticulous. I could probably do it again in half the time. I am happy. The mounting bracket (18144) I ordered with the harness had a cutout slightly too small to accept the 4-pin plug. I used files to enlarge it and eventually made it fit. I suggest try ordering a different bracket from another manufacturer. 591600

The 18144 bracket will not work with hopkins wiring harnesses. I recommend a brophy bracket part # BK4F

Good price. They had two like wiring harnesses for my 2013 Chrysler T&C. Because of their excellent DIY videos, I could compare, picked this one because little control module gets attached inside body under left tail light, whereas the Curt harness attaches the to the left inside of rear bumper- less than ideal in N Illinois. 594137

Everything we needed to assemble the cargo platform and comply with DOT. We had to modify some parts but I think that was due to our vehicle and not the product. 634093

- HM11141995

Product installs easily but pay attention to the instructions for running the power wire to the battery...the wire is only long enough to go the route listed in the instructions 328493

Took minutes to install. The box back by the trailer plug we hide behind the driver brake light. We also placed the ground screw there as well. One note is to drill the hole deep enough. There are 2 body panels. One about 1/4 inch behind the one you can see. Everything else plugged in. We followed the brake lines up to the front to connect the power wire to the battery. 634226

Wiring product works excellent . Had very well written instructions 696885

Wiring for trailer was easy just plug it into tail lights and follow directions. Most difficult for me was working from the ground routing the power wire for the trailer light module. As I am 74 I do not move as easily as I once did. It was hard for me to get under the van to route the power wire. A lift will make it much easier. 692845

Excellent fit and finish. Looks great on van. Took a little longer to install but I didn't have a lift and needed an extra pair of hands to lift hitch up into position. Watching the video is a great idea before you start. 438467


Ask the Experts about this Hopkins Custom Fit Vehicle Wiring

  • Trailer Taillights Not Illuminating With Hopkins Wiring Harness On 2016 Dodge Grand Caravan
    In most cases when only one function is not working properly or intermittently it means there is a bad ground connection somewhere on your setup. I would double check the ground connection on the vehicle Hopkins plug part # HM11141995 to make sure it is grounded to a clean bare metal surface free of debris or paint. Grounding issues tend to show up most with the running light circuit because those lights remain on continuously and so they draw more current. You also want to make sure...
