  • 90-Day limited warranty


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 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 - HM11142175 Review

Today we're going to be taking a look at the Hopkins plug-in simple vehicle wiring harness with the 4-pole flat trailer connector. This product fits certain years of the Dodge Caliber, Dodge Grand Caravan, Jeep Patriot, Chrysler Town and Country, and Dodge Durango. To see or double check if this is a fit for your vehicle, you can use the vehicle fit guide located at etrailer.com. The unit'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. Adapters are sold separately, and 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 the plug's not being used. The black box right here, this is the included power tail light converter. This connects directly to vehicle battery through the wiring to avoid overloading the vehicle's electrical system. Now, the unit is designed to connect quickly and easily. You don't have to worry about cutting or splicing any wires. Just locate the connection points behind the tail lights at the rear of the vehicle.

One of the connectors is going to go to the passenger side. The other one's going to go to the driver side, so locate the connection points, get these plugged in, custom fit for your vehicle, so the plugs are going to match up perfectly with the ports on the vehicle. They're going to snap lock together for a nice, tight, secure fit. Once you get those connected, you'll need to make a ground connection. That's going to be your white wire with a ring terminal attached to it. You want to get that grounded to a nice, clean metal surface with the included grounding screw.

Then you can mount your converter box to an out of the way location with the provided cable ties. Once you have all that done, you'll need to run your hot lead to the vehicle battery. The hot lead is the red wire with the butt connector 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, 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 vehicle battery. Then the fuse goes directly in this area here. It does come with your 15 amp fuse, and it's got the fuse cap that goes over and keeps that safe and protected. Once you have that done, you can secure any excess or slack in the wiring with the included cable ties. Then once your installation is complete, the 4-way connector is going to be stowed beneath the vehicle near the trailer hitch. We recommend a mounting bracket to keep the connector secure and easily accessible. Mounting brackets are sold separately. We also want to encourage you to use a small amount of the grease that's included. This is going to be used on the electrical connections, like the plugs on the vehicle and the 4-pole connector itself. That grease is designed to help prevent corrosion to the connection points. That's going to do it for today's look at the Hopkins plug-in simple vehicle wiring harness with the 4-pole flat trailer connector.

This would have been a snap to put on however, we did not receive enough wire to run it up to the front. So we had to go buy some. The fuse box in the back light did not go down far enough so we had to mount it in the tail light without completely seeing it. 660306

The product fit our jeep perfectly! We are looking forward to many trips to the lake hauling our boat using our Jeep Patriot instead of having to take the big truck. The video on the website on how to install was great. Hardest part of install is running the wire to the battery, but installing to the lights in the back was easy and worked just as explained. 547470

Easy hookup on the backside but running the power wire to the front was a challenge. Don't understand why I had to do it but I did. Works great since it's all hooked up. I have a small trailer and boat that I pull around with my jeep patriot. 511313

Ask the Experts about this Hopkins Custom Fit Vehicle Wiring

  • Running 12V Wire from Battery to Wiring Harness
    On your 2009 Dodge Grand Caravan, I am not aware of any 12V power that will be adequate for the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM11142175 installation. If you are concerned about the wire rubbing on the frame you can use wire loom like # 7509-10. I've attached an article to assist with routing the power wire to assist.

  • 2008 Chrysler Town & Country Left Running Light Stays On Even with No Trailer Connected
    It does sound like there is a problem inside of the converter box for the wiring harness on your 2008 Chrysler Town and Country. To test it you will need a circuit tester such as # 40376 or a meter if you have one. Have someone sit in the vehicle to operate the lights while you test. First test the wires going into the converter box from the vehicle. None should have power when none of the lights are on (except for the power wire on applicable wiring harnesses). If there is power then...

  • Which Ball Mount Should be Used with Curt Hitch that Fits 2011 Dodge Caliber
    Curt actually recommends a longer ball mount # C45016 with the hitch part # C11006 as it is a bit longer like you mentioned and has been confirmed to be the right rise/drop and the correct length. For hitch balls the part # A-82 would be what you'd need for a 2 inch ball or part # A-80 for a 1-7/8 inch ball. For trailer wiring then we have the part # HM11142175 which is an easy fit.
