7-Way Molded Trailer Wire Connector, 6' Long - H20044

Average Customer Rating:  4.7 out of 5 stars   (242 Customer Reviews)


Immediately, I could tell the quality of this trailer wire connector is much better than the china connector that the factory installed on my trailer. I anticipate this will definitely resolve the connection issues that I have experienced from day one with my new trailer. Sometimes you just have to solve problems yourself. I recommend using products from etrailer!


Soft and flexible cable sheathing. works well for my application to replace an old corroded plug connector


Seems like a good quality cord so I’m h appy.


The 7 way worked great and was a perfect match for my 2018 Ram 3500. I had to rewire substandard wiring and remove all the guillotine connectors on my 2017 GD Reflection 337RLS brake system. How they let this off the assembly line is beyond me. Intermittent truck alarms (check trailer) and brakes all the way from Mexico to WA...not fun. GD used 14 and 16 gauge wire with scotchlock connectors from the pin-box to the magnets...even had scotchlock splices inside the underbelly where you cant easily get too. Anyway I have 10 gauge marine tinned copper from the pin-box to the axles and circle connectors in waterproof boxes at the axles and legitimate crimped butt connectors with heat shrink (the good marine kind). I also bonded a 4awg ground to the frame at the pin-box and at the axles. What a disgrace that GD let this out of the factory. Anyway, Ive been very very happy with all the folks at etrailer...they care. See you on the road...Jim & Christine.


I felt the product was good, but the cord was not long enough. When I ordered it, the one I wanted had a longer cord, but was not available. I was in a bind so I took the shorter one. It works great, but it is not long enough for my needs. If I have to turn the trailer sharp the cord will pop out of the plug, due to the shortness of the cord. Good product.

I sold the trailer. The cord was still not long enough.

My drum brakes locked up on me because it is a boat trailer and gets submerged in water. I hate drum brakes, due how many part are inside and can rust up. I am the 3rd owner of my 1998 boat trailer and it was hard to figure out what I needed to fix it. I contacted etrailer and they were super helpful, super informative and super easy to work with. I told them what I had, and what I wanted to do., and they put a package together for me and that was them. Everything was super east to install because it is all bolt on. I did have to do some cutting and grinding on my old tongue because the master was welded on. That was the only difficult part. My new setup is amazing and the disk brakes and new master make it feel like my boat is not even there. All in all, I am 110% satisfied and will definitely be a returning customer for any trailer needs. Thank you etrailer for making everything super easy.


Used this product to extend the trailer's factory cable due to the new tow vehicle's receptacle was farther from the camper tongue. After one year, it is still working well.
All wire colors were correct.

Still working well!
Bill G - 04/13/2020


The connector is a good piece, however the colors do not match up. Anyone familiar with trailer and truck wiring knows that the wires are all color coded for a reason. If your not going to make the colors match up then why utilize the same colors? I hard wired everything neatly and then found out brown doesn't go to brown, and so on.... Had to test every lead to get it all wired properly... extremely aggravating. My suggestion is that the wires be run properly so they can all match color wise... and if that's not possible, then send a wiring diagram along with the harness when it is shipped.


Good service. I had called and confirmed the details about the cord and plug. The salesperson was very helpful and gave me a good target date for delivery. Got it today as was promised. I’ve got it installed and it works well. It has a quality heavy duty cord that is molded into the plug. Time will tell if my hopes for longevity is achieved.
Thanks and keep up the good service!!

Here in west Texas, it is dry and hot. The trailer sits outside and is in the elements. The cord and connector are holding up well. Works every time!! Thanks for providing a good product with service to match.
Terry W - 07/06/2020


Initially this product seemed perfect. It is stout and seems to be able to hold up to the wear and tear of the road. It fits far better then the cheap connector I picked up at the convenient store. The length was more than adequate to replace my old connector. However, after installing it my lights went CRAZY!! My passenger side turn signal was constantly on. When I hit the driver side turn signal all the lights flashed. The brakes did turn anything on. So I completely disconnected it and got out my trusted multimeter. Turns out that the brown wire went to the green on the trailer, the yellow to the brown, the green to the red, ect. It was a mess. Within 10 minutes I had the wires feeding the correct lights. I'm not sure if it is because Chevrolet doesn't use the industry standard or if my connector was defective. Either way it's fixed now and works great!! Even with all of those problems I still give it 4 stars.


Excellent! Has made my trailer safe as this replaced the original trailer wire connectors. Thanks!


i have been wiring 12 volt systems, hot rods, race cars, trailer of all types. although the plug worked like i wanted an this car trailer the color code reference chart is no way right. i did read this in the reviews before i bought it so i was ready for it.


E-trailer did a great job of getting this product out to me.


The items that I orderd were received in a very timley manner. I had originally ordered a different trailer pig tail and etrailer contacted me and let me know that the items were back ordered from the supplier and made recomendations on what they had in stock. The staff at etailer are very proffesonal and I will diffenitly purchase from them in the future.


Good solid connector at a great price. My hope is to introduce one less variable into the rewire of the utility trailer.


This was purchased as a replacement for my utility trailer's connector. The wires inside are of a heavier gauge than the connector it is replacing. And the insulation seems more tightly molded around the inside wires. It seems like a quality item.


Plug was not wired to standard. Wire colors did not match to the correct pins in the plug. Molded plug and wire quality is fine but lack of standard makes use unnecessarily complicated.

The turn signals and tail light functions of this molded plug are not the standard wiring colors. Please take a look at the chart on the product page to compare the wiring colors of the Hopkins to the standard wiring colors and their functionalities.
-- Etrailer Expert Heather A - 03/11/2021


Well made plug. This is the second one I have ordered. Even though it is well made, it does not hold up to being dragged down the road for 10 miles. Highly recommended.


The color coding of the wiring in relation to their position was all incorrect to what is recognized as standard. Since the plug is molded there is no way to switch positions of the wires. I had to use a continuity tester to determine what was what. The trailer brake circuit was the only one that was correct

There is more than one accepted color coding for a 7-way trailer connector, which is why we list the color code on the product description that shows which function each wire color carries. Heres a link to our Trailer Wiring help article that you might find helpful.
-- Etrailer Expert Mike L - 08/15/2018


Has held up well, fits my factory plug perfectly on my 2010 Ram. It's nice to have a clean connector install on the trailer, looks professional, looks better than my beat up trailer lol


great products and service as always


I will be using this cord between my motor home and Jeep. Nice and heavy duty.


Very nice quality product. It's nice to have a molded plug, and this fits the bill nicely. Length is adequate as well. Couple this with one of the trailer junction boxes (another excellent product) and you'll have a clean and professional installation.

All good. Havent used the trailer much tho.
GeorgeM - 11/01/2017


Was able to order compatible load bars for an older draw-tote hitch. Upon my fitst call to etrailer, they couldn't identify the part number I provided. I was given a phone number for Draw-Tite, who was sold to SCParts. They only provide parts to retailers, but they looked up the replacement part number, gave it to me, and said to call E-trailer with the partnumber, as they had found the item on E-trailers website, so after a runaround I was able to purchase my replacement load bars. Only comment I have would be to build a cross reference catalog for older weight distribution hitches


Great service and they all work great

  • How to Determine Wire Function for Replacing Trailer 5-Way with H20044 7-Way
    What you will need to do is verify the colors of the wire on your trailer. In some cases trailer manufacturers will use the standard wire colors to wire everything up, but there's no guarantee that's the case. Especially if someone else messed with the wiring at some point and didn't have all of the colors available. Trace each of the wires to be sure. It sounds like your white is ground, your wires bundled with brown are running lights but the rest can go a few ways that we have seen....

  • Installation of Hopkins Molded 7-way Trailer Connector
    You will need to connect the wires based on function and not on color since your trailer colors do not match. The color to function connections for the trailer plug are: white = ground black = 12V green = running lights brown = right turn and stop red = left turn and stop yellow= reverse blue = brakes

  • Can a Winch be Ran Off of the 7-Way Power Wire # H20044
    In theory yes you could connect the power and ground wires from your winch to the 7-Way Molded Trailer Wire Connector # H20044 to draw power from the battery in your tow vehicle. The problem is that the distance from the battery to the winch may not provide enough power to run your winch depending on how big it is and how much of a load you have on it. The best thing is to have an additional battery to run the winch only.

  • Could Male 7-Way be Wired to Front of 2014 Honda CR-V for Charging Battery When Flat Towing
    We have a 7-way with a 6 foot long harness part # H20044 that you could use to wire up like you mentioned. We don't have a more specific way to install a male 7-way on the front of a vehicle though so this would be your best option. The white and black wires of this have the heaviest gauge wire at 10 gauge so that would be the best to use for running to the battery.

  • Why is There 12 Volts on the Black Wire for my Trailer Connector
    If you are referring to the 12 volt pin that is located in the 1 o'clock position on the 7-way trailer connector then there should be 12 volt power feeding from the vehicle to the trailer on that pin. This means that if you test the 12 volt wire (usually black) before it enters and exits the controller, there should be 12 volts on either side assuming the 12 volt wire on the trailer is ran to a battery for maintenance changing purposes. Attaching two 12 volt power wires together will not...

  • What Does Yellow Wire of 7-Way Molded Trailer Wire Connector H20044 Wire To
    The yellow wire of the 7-way harness part # H20044 that you referenced goes to the center pin of the 7-way which is an aux circuit that is typically used for reverse lights if present on the trailer. Normally the red wire on a 7-way (RV standard colors) is for the left turn circuit so if you have a red wire I'd not think this would be the correct wire to connect the yellow if the 7-way to. Most likely you'd need to connect it to a yellow wire on your 7-way or to a purple wire. That said,...

  • 7-Way Trailer Wiring Connector for 2011 Nissan Pathfinder Towing Boat Trailer
    To install a 7-way on your 2011 Nissan Pathfinder you'd want the part # 118266 which comes with everything needed to install a fully functional 7-way on your vehicle. This has the reverse light circuit active too which is what activates the reverse lockout and allows your surge brake trailer to reverse without the brakes locking up.

  • Trailer 7-Way Recommendation to Fit 7-Way Connector part # PK11916
    I checked your order notes and it looks like you ordered the # PK11916. I attached an install video that shows this exact harness being installed on a 2013 Chevy Silverado just like yours for you to check out. This connector is compatible with the standard 7-ways that are often found on trailers. If you have something unique you can replace what you have on the trailer with a new connector like # H20044.

  • Trailer Wiring Connectors that Carry Reverse Light Circuit
    The most common trailer connector that carries the reverse light circuit is the 7-way. This is a very common connector style. Also the flat 5-way carries this signal as well. This is most common seen on boat trailers or others with surge brakes. For a 6 foot long harness with a 7-way we have the part # H20044. Or for a 5-way we have the part # HM47910. I also attached a help article on trailer wiring for you to check out too.

    Good thinking testing the truck with your other trailer, you've ruled out the truck as being the cause of the problem. Since all the trailer lights are functioning on the trailer, the problem is likely in the braking system. Start with the trailer plug, and closely examine it for damage or corrosion. If it's damaged or corroded, you can replace it with a connector like part # H20044 for a 6 foot long wire or # H20046 for an 8 foot long wire. Trace the brake output circuit back to the...

  • Wiring Needed to Convert 13-Pin on European Trailer to Standard U.S. 7-Way
    Since there are no adapters to go from a European 13-pin to a standard U.S. 7-way, what you are going to need to do is a bit of wiring. You will first need Converter # C56196 in order to combine the separate brake and tail lights that are on European trailers. After that you are going to need to install a standard U.S. trailer side 7-way, the 7-Way Molded Trailer Wire Connector - 3' Long # H20042 or 6' Long # H20044.

  • Recommended Durable 7-way Trailer Connector Pigtail
    Hopkins does a very good job of constructing their molded 7-way trailer connector pigtails for durability, I can highly recommend part # H20044, which is 6 feet long. The best way to connect this to existing wiring is to use a junction box like # 3375601101. A junction box allows you to tidy up the connections, protect them from the elements and provides an easy way to change out the pigtail in the future should it become damaged again.

Aside from just covering it up with something to help protect it, you will want to put some Dielectric Grease # 11755 on your trailer connector.

The US style 4 or 7-Way has combined brake lights and turn signals. What you will have to do create an adapter.
