Trailer-side connector is designed primarily for boat trailers that have hydraulic brakes. Easy-pull, heavy-duty connector housing lets you disconnect quickly and easily. Protective dust cover and terminal grease packet included.


Features:

  • 5-Wire design common on boat trailers with hydraulic brakes
    • 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
  • Terminal grease packet included


Specs:

  • Connector: 5-way flat
  • Wire length: 18"
  • Wire gauge: 16 gauge
  • 3-Year warranty


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.

The product arrived in a timely manner and undamaged. I have not used this 5 pole adapter yet, but the 4 pole adapter I previously bought from etrailer years ago is still working great. I have no reason to doubt that this adapter will function equally well. I appreciate the good products and customer service from Etrailer.




by:

Good quality. Used on my boat and connection to truck has been good. No flickering lights.




by:

this item was inexpensive and did the job for which it was ordered perfectly. It was used to connect to a 5 pin wire coming from my RV in place of the typical exposed bulky receptacle found on the front of many towed cars. This was installed under the hood of my car and could be flipped out to connect to the RV coiled pigtail. The fifth wire, which is typically used for back up was instead used to provide power to keep the battery charged when connected to the RV with the RV engine running. This has proven to be sturdy and after a year of use has continued to perform as virtually new. The small whole in the sides allows me to connect the two plugs and use a "wire paperclip" to assure they wont unplug due to an excessive tug when towing. buy again and recommend YES.




by:

I bought this to replace the 5 pin connector on my boat trailer after an electrical short melted the connector.

Connection is solid to the 7 to 5 pin adapter. Protective cover is nice to have as the boat trailer spends its time sitting outside.

Only complaint I had was one of the pigtails was a non-traditional color so visually it looks off when wired up to traditional trailer wiring. Can't recall which was off as I no longer own the trailer.




by:

Solid product, great service!
It was
a little confusing, du to my trailer had 7 wires and the current plug had 6 wires. I phoned a friend.. LOL

Glad you have a friend that could help you Mickster! Dont forget that etrailer.com customer service is available to help you if you should run into problems.Thanks for taking the time to write a review!!

etrailer.com was great. The plug arrived as expected and packaged well. It is well made and appears it will last for many years. The only thing is I wish the wires and the protective sleeve was longer. I would have liked to spliced it back where it entered the trailer but ended up using butt connectors with shrink wrap that show in the middle of my wiring. Had to use the old rubber tube protector half way and the new mesh protector on the plug the other half with butt connectors between two types of cover. I covered those with black tape, not very pretty but works well.




by:

I just got my order in on Monday the delivery was a fast turn around. I am in the the process of converting my boat trailer lights to all submersible LED lights. The five flat wires are clearly marked which will make splicing a snap. I am converting from a four flat plug to a five as I also am installing reverse LED back up lights on my trailer. The five flat to a seven round adapter allowed me to do that. The quality of the product on a scale of 1-10 in my opinion is a 10. The 7 round to five flat adapter is also a 10 in my opinion. Very happy customer thanks etrailer I will continue to do business with you again.




by:

Worked as intended. Stress relief off the plug is a plus as well as the dust cap. Used it to power an LED light bar from the trailer circuit. Light bar is temporarily mounted on the swim deck of my boat when towing.




by:

Being a new boat owner I was quickly overwhelmed by what I didn't know. Re-wiring, re-lighting my trailer was my first project. etrailer has a wide range of products, but most important to me, was their added product information and instructional information which helped me make the right selections to get this done. Add to that is their very competitive prices. etrailer will be my go to source for my future trailer needs.




by:

Worked great




by:

Hitch fit great. Installed it myself. Wiring was plug and play. Was a little difficult to get to the wires behind the panels. I do recommend this hitch.




by:

All the products I purchase from etrailer (most recently trailer bearing grease and five pin trailer plugs) are always high quality and do the job they are designed to do. The prices are reasonable also.




by:

These are the best! I can not tell you how many connections I have replaced over the years until I got these. They are strong and the wires are protected so they do not break at the connection point. The wrapping is so much better than tape or other forms of protection. I have changed all my connections on both vehicle and trailer with these units. I am very happy with the product.




by:

The trailer pigtail ordering process was quick and easy, delivery was fast and the product was very high quality. Good experience all the way through.

That what we love to hear Larry!!! Hopkins appreciates your business and we are grateful you purchased our Trailer Connector. Thank you !

Pretty straight forward product. Not sure how much I care about the 'ergonomic design', but the nylon sleeve and heat shrink saved me the trouble.
Good price, and fast shipping.
You can't go wrong with etrailer. I have bought many items from them, had an issue with one, and their customer service was excellent. They replaced it immediately. This is the first place I go to for trailer parts, and they have some other cool products they sell as well.




by:

Great product for a fair price...looking for a 50mm hitch ball but was not a stock item so etrailer ordered it from the manufacturing co. Ashley is great to work with...if she doesn't have an answer for a question she will find someone who does. Highly reccomend this vender.




by:

Both the wiring harness and the customer service was excellent! Can't get any better ??




by:

Exactly what I ordered and timely shipped. I love the tutorial videos really made trailer wiring easy to understand......I will definetly use etrailer again.




by:

Have yet to install but it's Spears to bea quality product. The service from trailer was excellent! Always has been and have never disappointed.

Working out well! Harness carries all the electricity it needs to!

I re-wired my boat trailer and up-dated my lights with these things.. great products worked better than I thought !




by:

Great quality product! Used this on my disc brake upgrade to my boat trailer. Needed the 5th pin for the backup lockout on the coupler. Works like a charm!




by:

Quality product




by:

Just what was needed to connect my new motorcycle trailer. Local trailer store didn't carry the one connector. Can always count on etrailer to have what I need.

Easy to install.

Great shipping and heavy duty connector. Highly recommended

  • Troubleshooting Trailer Tail Lights not Working when Tow Vehicle Head Lights are On, Toyota Tundra
    This to me sounds like a ground problem. It sounds like your tail lights function until the additional load of having the head lights of your vehicle are turned on and then the lights cut out. The reason this manifested after the vehicle swap could be a lower voltage output of your latest vehicle. Either way I would check the grounds on the tail lights of your vehicle and make sure they are making a good connection to a clean metal surface. I attached an FAQ on trailer wiring for you...

  • Adapter For 5-Flat Towing Plug to 4-Flat Trailer Light Plug
    If you were wondering if you need to make the trailer a 5-way, technically a 4-way and 5-way can plug into each other, so you don't have to do anything. You don't even have to wire the vehicle side. But if you want the function of the 5th pin, then you will need to add a 5-way to the trailer and wire it with # HM47910.

  • Wiring In a New Trailer Side 5-Way Trailer Connector
    Wiring by color can prove to be a bad idea since there technically isn't a standard for wire function and color. On Hopkins trailer side 5-Way, the white wire is the ground, brown is for running lights, yellow is left turn/brake lights, green is right turn/brake lights, and blue goes to the reverse lockout solenoid like you said. To determine the functions of the wires on the trailer you could either trace each one back to see where each goes. Or you could apply 12 volts of power to...

  • Could the Hopkins Endurance 5-Way Flat Trailer Connector # HM47910 be Used for a Reverse Lockout
    The fifth circuit on the Hopkins Endurance 5-Way Flat Trailer Connector # HM47910 that you referenced can be ran to a reverse lockout solenoid like what you have on your trailer. You mentioned a video where this was used for a brake output circuit, but the more common use of a 5-way is for the solenoid like what you have. The install video I attached shows it being used for a reverse solenoid.

    If the Automatic Headlights are the issue, then you could remove the fuses that control the headlights on your 2002 Chevrolet Tracker. I looked up the owner's manual for your vehicle and found the headlight fuses are located in slot 3 and 4 of the fuse box that is located in the engine compartment. You will just have to remember to re-install the fuses in your Tracker when it is not connected to your motorhome. If your Tracker was wired correctly for flat towing, then driving at night...

  • Replacing 5-Way of Trailer that Has 7 Wires with 5-Way that Has 5 Wires
    For a replacement 5-way for your trailer the best option is the part # HM47910 which you'd need to wire by function to your trailer wiring keeping in mind that some of the circuits may be duplicates which would wire to the single wire of the 5-way. You can use a jumper wire from a vehicle battery positive post to each of the wires of your trailer to determine function and then wire accordingly.

  • Replacing 5-Way on Trailer that Has 8 Wires
    A standard 5-way like the part # HM47910 would work great to replace what you have. You'd just run all of the white wires that you have (all three) to the single white wire of this connector, both the brown wires to the single brown of the connector, and then match the rest of the wires by color and you'd be set.

  • Can 5-Way Trailer Wiring Connector be Used with Trailer Brakes
    Yes, a 5-way trailer connector can be used with trailer brakes. You'd have to make the 5th circuit of the 5-way the brake output circuit and you'd be set. Normally this is used for a reverse light circuit for a reverse lockout circuit but if you wired it up to be a brake output circuit it would work perfectly fine.

  • How To Install 5-Way Trailer Connector with Five Wires On Trailer with 5-Way and Eight Wires
    It's pretty easy to wire up a 5-way flat with five wires in place of a 5-way flat with eight wires. There are multiple wires with the same function, you'd simply be combining these wires into one. I am not sure exactly what you have so you would need to test for this but usually there are multiple grounds and running light wires so you would just tie the multiples into one another before attaching to the new lead.

  • Replacement 5-Way for Trailer that Has 5-Way with 8 Wires Ran to It
    Your current 5-way has two wish boned circuits. One on the running lights and for the reverse light circuit which is why two wires run to each pin. All you'd have to do is run both of the trailer wires of each circuit to the single wire of the replacement 5-way like the part # HM47910 and you'd be set. It would function just fine as this is a very common situation.

  • What Gauge Wire does the Hopkins Endurance 5-Way Flat Trailer Connector # HM47910 Use
    I went out into our warehouse and pulled a Hopkins Endurance 5-Way Flat Trailer Connector - Trailer End, part # HM47910, and it has 16 gauge wires.

    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....

    For a replacement 5-way for your utility trailer I would recommend you get a Hopkins 5-way part # HM47910.

  • Towing Trailers with 4-Way Connectors Using a Vehicle With a 5-Way Connector
    Actually, you don't have to change anything. The 4-way connectors on your trailers fits into the 5-way on the vehicle except you'll have an extra pin not being used. Since it's the trailers that are missing a pin that means you don't need that function, which is likely a reverse light circuit. If you want you can replace the connectors on both trailers with a 5-way like part # HM47910 but you still won't use the function of the fifth pin. The other option is to replace the 5-way on...

  • 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...

    There are many different ways that you can connect the 4-pole connector on your trailer to the 5-pole connector on your vehicle. If the 4-pole and 5-pole connectors on your vehicle and trailer are the flat style connectors, then you could simply plug the 4-pole trailer connector into the 5-pole vehicle connector. Doing this would leave one slot exposed on the vehicle 5-way connector, but that slot is usually attached to the reverse light circuit which you do not need. In some cases the...

  • Can a 4-Way Flat Connector on a Boar Trailer be Plugged into a 5-Way Float on a Tow Vehicle
    You can just plug the 4-Way connector on the boat trailer into the 5-Way connector on the vehicle and it will work; just like you have described. There are some cases where some 4- and 5-Way connectors will not physically plug into one another. If that is the case with your set up you could splice in a 5-Way on the trailer using # HM47910 and just put a wire nut on the very last wire since it will not be used on that particular trailer.

  • Do I Need an Adapter to Go from a 5-Pole Flat Vehicle Connector to a 4-Pole Flat Trailer Connector?
    Typically the 5-Way Flat is used for trailers with surge brakes or hydraulic brakes. The additional wire is tapped into the backup lights to disengage the hydraulic trailer coupler (actuator) when the vehicle is reversing, thus turning off the trailer's brakes. That being said, there isn't an adapter out there to convert a vehicle's 5-pole flat into a 4-pole flat because it's not needed. All you have to do is plug the 4-pole trailer connector into the 5-pole vehicle connector. Doing this...

Once this is done you can use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter part # 20036.

For the combined circuits like the red wires, white, etc. you can run them all to a single wire on your new 5-way connector like the part # HM47910.
