    • Provides backup function to release surge brakes
    • Fits most 4-way connectors
  • Easy-pull, ergonomic grip on connector makes disconnecting a snap
  • Heavy-duty connector housing has built-in mounting holes
  • Durable, molded dust cover provides superior protection for terminals
    • Tin-plated terminals resist corrosion
  • Nylon sleeve and heat-shrink tubing protect wires

The 5-way flat connector is found on most newer boat trailers that have hydraulic brakes. The fifth wire in this model ties into the reverse lights on your vehicle so that a signal can be sent to your hydraulic brake actuator to disengage whenever the tow vehicle is put into reverse. To use this function, your actuator must have an electric reverse lockout with solenoid.


The 5-way design will also work with small utility trailers that have electric brakes. For this type of application, the fifth wire will need to be wired to correspond with your in-cab, electric brake controller.

I fitted the Hopkins 5-way flat connector harness with a 5-way round plug which couples to my Goldwing trike (tow vehicle). The popup trailer lights operate as designed.



by:

Connector and wire harness well made - connector designed such that it can be mounted and harness has added protection for wires.


Would like to have marine grade wire since I do mostly saltwater fishing. I mounted the connector on a piece of 1.5" square galvanized tubing painted black.



by:

Used this on my 2018 Equinox for my flat tow tail lights.



by:

Worked great on my 2022 Civic Sport Hatchback. Unlike the previous generation (2021 and older) you DO NOT have to trim the internal metal bumper for clearance of the outer plastic bumper. Trimming the lower diffuser was pretty easy and only required a 3-1/4 in cut in depth and about 2-1/4 in width (If you want the gaps super tight). Remember to tape off the panels before you get started to prevent chips and paint scratches and you'll be set.



by:

I'm one of those people who do a lot of research before making a purchase. I am very happy with the quality of the Hopkins trailer connector and would highly recommend it.. Good quality products and excellent service from etrailer.com

Still 5 Stars! E-trailer always has what I need!



by:

Items were delivered as described and on time,Great experience!



by:

Delivery was faster than I expected. I bought a converter with the appropriate adapters to go from a 4 wire vehicle to a trailer with turn signals separate from the brakes. I haven't done my final assembly yet, but I did take a few minutes to twist the wires together to make sure everything was going to work like it was supposed to. Instructions were clear, wires & converter were clearly labeled & preliminary hook up took less than 10 minutes.



by:

ONE YEAR AFTER THIS WIRING HARNESS IS STILL WORKING GREAT . THE PART IS JUST WHAT I NEEDED AND THE SERVICE AT ETRAILER IS AWSOME..... I LIVE IN WISCONSIN WHERE THE WINTERS ARE VERY COLD AND THE ROADS ARE VERY SALTY AND IT HAS HELD UP GREAT.... AWSOME PRODUCT



by:

Not installed yet due to weather & travel. Prefer to 5 pin adapter kit. Like extra cable / wire length to connect to Jeep wire harness so all connections are in a protected space. Heavy duty and like dust cap.



by:

This connector is built to last. A big step up from most flat 4 or 5 wire in quality.
With it's secure fitting dust/dirt cover I have no worries that the terminals
will stay clean and always make a good connection . The 3 year warranty is a
plus also.



by:

etrailer is a great place. They have both quality equipment and parts, as well as excellent prices. If you need some advice, they can supply that as well. It is rare in the days of internet buying that you can find all three qualities from one store.



by:

Product exactly as described. Etrailer.com delivered to my door within 3 days! As always excellent communication and transaction.
Will continue to use them for all my trailering needs.



by:

I needed to change from a 4 prong trailer connection to a 5 prong. The product was easy to wire and works great. A good product and I would recommend it to anyone.



by:

Great Product. Each terminal is identified in the plastic plug end - making wiring and troubleshooting easier.

Comes with a decorative and protective loom and covering end cap.



by:

A quality built wiring harness. Heavy duty and well constructed.



by:

Excellent product with simplicity made this a breeze to connect. works like a charm!!



by:

Attached easily. Nice that NO extra bracket is needed to attach to the bumper.



by:

Great quality piece. Will made wiring my Jeep to my trailer so much easier.



by:

Great quality, good materials, good wire gauge, covers built in. Just all around nice.



by:

See review for the other side of the harness. Both sides are well identified.

We are a hitch install shop that specializes in all things towing and this wiring was installed multiple times over the last year, this is the best wiring to upgrade to the 5 flat that will last long because the wires and 5 flat head is more durable than some alternative options.



by:

Installed product without a hitch, been working as expected.



by:

Great product, good prices very good customer service would highly recommend.



by:

Just what I was looking for. I was unable to find a similar product at the local parts stores.

  • How to Make 5-Way Flat to 5-Way Flat Adapter
    You'd have to take two 5-way males like the Hopkins part # HM47900 and wire them together to have a 5-way flat to 5-way flat adapter.

  • Can Blue Wire of Hopkins Endurance 5-Way Flat Trailer Connector HM47900 be Used for Reverse Circuit
    The blue wire of the # HM47900 can be used for basically any circuit. Typically for 5-ways like this the reverse light circuit is the most common circuit ran to the 5th wire. So this would work well for your application.

  • What is the Wire Gauge Size for the Hopkins Endurance 5-Way Connector # HM47910
    I called Hopkins to double check the wire gauge on the Hopkins Endurance 5-Way flat trailer connector, # HM47910, and # HM47900. I also pulled the wiring harnesses to see for myself which wire size the harness is constructed with. Our technical representative at Hopkins checked their build data and said the wires for both harnesses are 16 gauge wires. So with all of the discrepancies, I decided to pull some wire and produce a short video detailing the size of the wire for you, see link....

  • Replacement for 5-Way Trailer Connector with 9 Wires
    For a replacement 5-way trailer connector, I recommend the Hopkins Wiring Harness with 5-Pole Flat Trailer Connector part # HM37918. In regards to installation, you really need to test the wires for function to determine their purpose but if I had to guess I would say the red is for the reverse lockout or running lights, green for right stop/turn, yellow for left stop/turn, and white for ground. The extra wires will just be combined into once but you should verify each of the functions prior.

    If you wanted to make a 5-way extension you would want to use the part # HM47900 and then the # HM47910 as well. You would need to connect the wires of each connector together matching them by color and you'd have a 36 inch long 5-way extension.

    For a nice clean connection, you can use the Hopkins Endurance 5-Way Flat Trailer Connector - Vehicle End - Ergonomic Design # HM47900 to connect to your 4-way wiring and then add the reverse power lead from behind your tail light. Another option is to use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036 which has just the 5th function wire to connect to your reverse signal. This adapter simply requires less splicing. I've attached a video of this install to assist. I've...

  • Where Does Fifth Pin of Trailer 5-Way Run to Activate Reverse Lock Out Solenoid
    Sounds like you are trying to activate a reverse lock out solenoid on a surge brake trailer so that it can back up freely. The fifth pin that is the furthest from the jacketed ground pin is the fifth circuit to use. This circuit would need to tap into the reverse light circuit of your tow vehicle. I attached an install video for the 5-way adapter part # 47515 that shows this process on a 2014 GMC Acadia.

  • Availability of Plug-and-Play Wiring Harness for 2008 Kawasaki Vulcan Nomad
    We do offer any plug-and-play trailer wiring harness for the Kawasaki Vulcan Nomad. The parts you will need will depend on the type of connector and wiring scheme on the trailer you intend to pull. Your Vulcan uses separate wiring for its stop and turn signals. If your trailer is wired in the same way you could simply wire in on the bike an appropriate 5-pole vehicle side connector, such as Hopkins # HM47900. If you'd like to tell me about the trailer's wiring system and its connector...

  • How to Convert 4-Way of Motorcycle to 5-Way For Towing Trailer with Separate Tailligths
    In order to be able to use the 4-way on your motorcycle you will need a converter like the Tow-Ready Vehicle to Vehicle Taillight Converter, part # 118158. You will need to cut off your motorycle's 4-way and then wire this in place of it and then from there run it to a 5-way like the part # HM47900. The running light circuit of the original wiring will bypass the converter box.

  • Creating a 6-Way Round to 5-Way Flat Trailer Wiring Adapter
    We do not carry a 6-way to 5-way adapter, so I recommend making one using the Hopkins Trailer Connector Adapter - 6-Pole Round to 6-Pole Square # HM47415 and removing the 6-pole square to replace with the Hopkins Endurance 5-Way Flat Trailer Connector - Vehicle End - Ergonomic Design # HM47900. You won't use the 12V feature so I recommend removing that wire from the 6-way so it doesn't draw any power. I've attached a wiring article to help with the connections.

  • How to Use 4-Way Wiring of Trailer to Power Interior Lights from Battery
    You'll need to first convert the 4-way of your trailer to a 5-way since a 4-way does not carry an aux circuit that can be used for interior lights. If you were to wire the interior lights to 4-way wiring you'd end up having to have the exterior trailer lights powered at same time since it would have to be combined. So on the trailer end you'd want to install the part # HM47910 matching the current circuit colors with what you have now and then having the 5th pin run to the interior lights. Then...

  • How to Create an Adapter for a Vehicle's 6-Way Round to a Trailer's 5-Way Flat
    We do have a way for you to connect your 6-way round and 5-way flat. We don't have a direct adapter, but a combination of two with a bit of splicing will do the trick. First, use part # HM47415 to convert your 6-way round into a 6-way square. Then, remove the 6-square from that and attach part # HM47900 to give you the 5-way flat connection point. I've linked to a help article of wiring to help you with this along with video reviews of both of the adapters. You won't be using the 12V...

  • Replacing 7-Way Trailer Connector with Smaller Connector to Tow a Trailer with Brakes
    A 6-way round trailer connector, like # HM48420, once it's mounted isn't going to be much smaller than a 7-way. If you don't need any functions other than running, brake, and turn lights along with the brake circuit I suggest going with a 5-way flat connector like # HM47900. To put a 5-way on both your tow vehicle and trailer you can use the kit # HM47890 that includes both connectors.

  • Locating Reverse Light Circuit on 2001 Dodge Ram 1500
    I do not have any information that is specific to your 2001 Ram, but I can certainly help you through the process. The easiest way to do this is to access the rear of one of your tail light assemblies, as if you were replacing a burned out bulb. Once you look at the rear of the assembly, it should be immediately evident which wire feeds the reverse light (clear bulb). You would tap the wire with the blue stripe into that circuit, using a butt connector like part # DW05714. Be sure to wrap...

  • Is Adapter Needed to Tow Trailer with 5-Way Flat with a Harley Ultra Classic with 4-Way Flat
    Many times a 5-Way flat trailer connector will plug into a 4-Way flat connector. But if it doesn't then you would need an adapter such as # 47515. If the trailer is designed for use behind a motorcycle I am curious as to what the functions are for each of the 5 pins. On a typical 4-Way flat connector on a vehicle there is aground pin, running light pin, left turn signal/brake light pin, and right turn signal/brake light pin. And on a vehicle with a 5-Way flat the functions are the same...

  • Recommended Load Resistor Adapter for LED Lights
    It sounds like you are looking for a 7-way adapter with the integrated load resistors. We do have that adapter...it is the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142. This works great for trailers with LED lights. I assume the 7 flat is the blade style and not the European 7 flat which we don't have the adapter for. It is the route to go before using individual function resistors like the LED Light Bulb Load-Resistor # DI34ZR which...

  • Troubleshooting Trailer Running Lights Not Working, Turn Signals and Brake Lights Do Work
    The white wire is probably the ground wire, and it needs to be connected to a clean, corrosion free bare metal surface on the trailer frame. Without a good ground, some or all of the trailer lights will not work or work properly. You can also check the grounds for each taillight. Trailer taillights usually ground through the mounting studs and they, too, will need to be attached to a clean corrosion free bare metal surface. There is not always a universal wiring color code that everyone...

  • Adding Trailer Wiring to a Motorcycle to Tow a Trailer
    Motorcycles have separate brake lights and turn signals. Most trailers, unless designed for use with a motorcycle, have combined turn signals and brake lights.

On this harness you will connect the white to ground, green to the left turn signal, yellow to the right turn signal, and red to the brake lights. Brown is the running lights. If it is...
