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 and some interior paneling 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 in your trunk.


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 - HM11141824 Review

Speaker 1: Today we're taking a look at the Hopkins Plug In Simple Vehicle Wiring Harness with a 4 pole Flat Trailer Connector. This product fits certain years of the Toyota Camry, Toyota Corolla, Toyota FJ Cruiser, Mazda MX5 Miata, Mazda 3, Mazda 6, and Mazda CX7. To ensure or double check that this is a fit for your vehicle, you can always use the Vehicle Fit Guide located at etrailer.com. Now once installed this unit provides a 4 way flat trailer 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. It comes with a dust cap with a 4 way flat connector that way you can cover up the connection points whenever the plug's not being used.

All the wires run to this black box. This is the included tail light converter. This ensures that your vehicle's wiring matches that of your trailer's. The power module connects directly to the vehicle battery through the wiring to avoid overloading the vehicle's electrical system, so it completely bypasses everything else and goes directly to the vehicle battery.The unit does feature a protective connection terminal to resist rust and corrosion, and it connects quickly and easily. It does come with detailed installation instructions to help walk you through the whole process step by step.

So, basically what you need to do is locate the connection points behind your tail lights, and plug in all of your connectors. These connectors are custom fit for your vehicle, so they're gonna match it perfectly with the ports on your vehicle, and they're gonna snap and lock together for a nice, tight, secure fit.Once you have all of those plugged in you'll need to make a ground connection. That's your white wire with a ring terminal attached to it. You want to get that grounded to a suitable grounding location with the included grounding screw, and then you'll need to mount the converter box to a safe out of the way location. You can do that with a double sided adhesive foam tape supplied as well as using some cable ties.Next you'll need to run the hot lead to the vehicle battery.

That's the short red wire coming out of the box. It already has a butt connector attached to it. This gets connected to one end of the bundle. The other end of the bundle runs to the vehicle battery. It gets connected to one half of the fuse holder with another butt connector.

The other half of the fuse holder has a ring terminal on it, and gets connected to the positive post in the vehicle battery. It does come with your 15 amp fuse. It goes directly in the fuse holder, and it's got the fuse cap that goes over it to keep it safe and protected.Once you have that done, you can secure any excess or slack in your wiring with the included cable ties. Once your installs complete the 4 way connector will be stowed in the trunk of your vehicle, or in the rear hatch area. It is recommended that you use a small amount of grease, or terminal grease, which is supplied on all the electrical connections like the plugs on the vehicle and the 4 pole connector itself to help prevent corrosion. When it comes to the maximum amperage for the stop and turn lights we're looking at 3 amps per circuit. For the tail lights we're looking at 6 amps per circuit.That's gonna do it for today's look at the Hopkins Plug In Simple Vehicle Wiring Harness with a 4 Pole Flat Trailer Connector.

Do you have a question about this Custom Fit Vehicle Wiring?


  • What Hitch Fits a 2016 Mazda 3 Hatch i-Touring
  • When it comes to "Vehicle Style" in our fit guide, there are 4 options in the drop down menu for a 2016 Mazda 3 - "Hatchback - with LED Taillights", "Hatchback - without LED Taillights", "Sedan - with LED Taillights", and ""Sedan - without LED Taillights". Since you mentioned your Mazda was a Hatch i-Touring, that narrows things down to the pair of hatchback options. Choosing either one of those options from the drop down menu will bring you to the two available hitches, the Draw-Tite...

  • Recommended Tow Package for 2018 Mazda 3 Sedan
  • To set your 2018 Mazda 3 up for towing a light trailer you will need a trailer hitch, wiring harness, ball mount, and hitch ball. Starting with the hitch I recommend the Draw-Tite Sportframe Trailer Hitch Receiver # 24912 because it offers the easiest install process that doesn't require any modification to the underbody trim panel on your vehicle like with the other available option. It is a Class I hitch that features a 2,000 pound towing weight capacity and will provide you with...

  • Recommended Cargo Carrier for 2015 Mazda3 Hatchback
  • You can use a cargo carrier with your 2015 Mazda3 hatchback but it will need to be a fixed carrier and not a folding carrier. The reason for that is the only trailer hitch that fits your '15 Mazda3 is a Class I hitch that requires the stability that a fixed carrier offers as opposed to a folding carrier. For a hitch I recommend the Draw-Tite # 24914 which fits your hatchback and is a Class I hitch with a 1-1/4" receiver and 200 lb tongue weight capacity. What this means is the combined...

  • Recommended Towing Set Up for 2018 Mazda 3
  • We have towing components you can add to your 2018 Mazda 3 though I did take a look at the owner's manual and it stated that you should not tow a trailer with your vehicle so doing so would be at your own risk. If you do decide to tow you need to start with a trailer hitch, either the Draw-Tite # 24912 if your '18 Mazda 3 is a sedan or the Draw-Tite # 24914 if your Mazda is a hatchback; these are the best option because they will be the easiest to install. The ball mount that Draw-Tite...

  • Trailer Wiring Recommendation for 2018 Mazda 3
  • The two harnesses you mentioned are made by two different companies which have different fit lists for the 2018 Mazda 3. The part # 118405 has been confirmed as a fit for the Sedan models but not hatchback whereas the Hopkins kit part # HM11141824 fits all models of the 2018 Mazda 3. It's also the only custom fit option that does this so it would be your best option.

  • Towing Capacity and Trailer Hitch for 2019 Toyota Corolla
  • I looked up the owner's manual to your 2019 Toyota Corolla and it states that the vehicle is not designed to tow and that Toyota doesn't recommend towing with it. With such a new vehicle I recommend checking your own manual or with Toyota to see if they can provide a tow rating. If you find you can tow with the Corolla we do have hitches available. I recommend the Curt, part # C11265, because it is tucked under the bumper by about an extra 1/2 inch compared to the Draw-Tite. Since...

  • Can a Wiring Harness be Used With a 2008 Mazda Miata?
  • You are not missing any success stories regarding the Hopkins Wiring Harness # HM11141824 from customers with a Miata, it is likely because the vehicle is not made for towing. I took a look at the owner's manual for a 2008 Mazda MX-5 Miata, and the trailer towing section reads "Never tow a trailer with your Mazda MX-5." It may not seem like a particularly dangerous thing to haul a small cargo trailer, but the weight adds stress to your Miata that it was not designed to handle. This could...

  • Recommended Trailer Hitch For 2015 Mazda 3 Hatchback with LED Lights
  • The Curt Trailer Hitch, part # C11377 is designed to fit your 2015 Mazda 3 Hatchback. This is a Class l hitch and it has a 1-1/4 inch receiver opening. A note form Curt states that all non-trailer loads - bike racks, cargo carriers and so forth - should be supported with stabilizing straps like part # 180050. Failure to properly support these loads will void your hitch warranty from Curt. If you plan on doing some light towing with your vehicle I recommend a ball mount like part...

  • Trailer Wiring Harness for a 2015 Mazda 3 Hatchback without LED Tail Lights
  • Hopkins does list wiring harness # HM11141824 as a fit for the 2015 Mazda 3, hatchback or sedan, with or without LED tail lights. There is another option that is universal but does not require splicing. It is the ZCI harness # 119250KIT and it has connectors that clamp around the vehicle tail light wiring to sense the electricity flowing through. What makes this such a great option, besides the fact that you won't have to splice, is that you can use it on many vehicles. So if you changed...

  • Plug-In Trailer Wiring Harness for a 2016 Mazda 3 Sedan without LED Tail Lights
  • For a 2016 Mazda 3 Sedan without LED tail lights you can use # HM11141824 which plugs in line with the vehicle tail light wiring so you won't have to splice wires like you would with some of the other options. I cannot recommend using a wiring harness that the manufacturer states not to use so it would be best to replace the harness you have with # HM11141824.

  • Recommended Trailer Hitch and Wiring for 2019 Toyota Corolla
  • The Curt Class I Trailer Hitch # C11265 and the Draw-Tite # 24913 for your 2019 Toyota Corolla are indeed extremely similar hitches but I recommend the Curt # C11265 for a couple of reasons. Both hitches will install at the same location on your Corolla but the Curt receiver will be just a bit more recessed behind the bumper allowing for a cleaner appearance. Unlike the Draw-Tite hitch, the Curt is also made right here in the USA so you can be certain of its quality and strength. I...

  • Trailer Hitch and Wiring for a 2015 Mazda 3s Hatchback with LED Lights
  • We have yet to have someone come in with a 2015 Mazda 3s hatchback to have a trailer hitch installed so that is why you don't see a video for it. But I have linked the installation instructions for you which contains step by step instructions with pictures detailing the installation process. If you plan on doing some towing with the hitch the correct ball mount to use is # C45521. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. And for trailer wiring you will need...

  • Why Does Trailer Wiring Connectors for 2009 Toyota Camry Not Match Taillight Connectors
  • You didn't mention whether your 2009 Toyota Camry is a Hybrid model or not, but the part # HM11141795 that you referenced is for the Hybrid models only. Which if yours was a non-Hybrid you'd want the part # HM11141824 which seems to be the issue you are experiencing since this kit uses 2-pin connectors like what you said you have and the # HM11141795 has 4 like what a Hybrid would require.

  • 4-Way Trailer Wiring Kit Recommendation for 2009 Mazda MX-5
  • A 6-pole flat connector is not a common style of trailer wiring connector so we do not have any adapters to go from a 4-way to a 6-pole flat. Best option would be to install the Hopkins trailer wiring kit part # HM11141824 and then remove the 6 way and install a 4-way in it's place with the part # A10-4404VP.
