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

Average Customer Rating:  4.7 out of 5 stars   (257 Customer Reviews)


by:

The color coded wires did not match the standard for which went where. I first assumed it matched and installed accordingly. Only ground (white) and electric break control (blue) were correct. Brown, yellow, and green were all wrong. I believe black and red were also switched, although those seem to be less standardized. Then I checked it for continuity with multimeter and reconnected, crossing colors as necessary. Also, outside sheathing immediately separated from molded plug during first use. This appears to be very nice, heavy construction, but in reality it is a big disappointment.


Comments
There are two different accepted wire color code conventions for a 7-way trailer connector, which is why we provide a chart see above showing the wire color codes applicable for this trailer connector.

Quality product. I’ve rewired several trailers using this product. I’d recommend it to anyone needing to build or rewire a trailer.




by:

Shipped faster than I expected. eTrailer is the way to go!




by:

Product was delivered quickly and installed easily. Lights are on and working




by:

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!




by:

Plenty heavy for whatever you are looking for. I just pull a Jeep and did not need this heavy a cord, but it works just fine.




by:

Easy setup works well




by:

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




by:

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




by:

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.


Comments
Still working well!

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.

They are great to deal with

Exactly what I was expecting to receive,

Well constructed

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.




by:

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


Comments
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.

by:

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.


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


by:

Plug seems ok, not really impressed with the flexibility though, in the sun it’s nice but around 50 degrees With no sun it got very stiff. I don’t see it working very well in cold temperatures. Next time I’ll have to look for a better option.




by:

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




by:

The products help you take the work out of what you need to do made easy




by:

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.


Comments
I sold the trailer. The cord was still not long enough.
Mike M - 02/08/2018


by:

Products were all as described and good quality. The only problem was packaging. The insulation on the wires on one of the brake assemblies was cut requiring splicing. Not a big deal but did require additional time and effort since they were cut where going through back plate. Wish I had purchased two conductor brake wire. Would have made job easier.But that was my mistake.


Comments
No problems, everything working as it should.
Russell H - 04/15/2016


by:

The products were ordered on Sunday night late, delivered by Wednesday. Converting drum surge brakes to disc, electric over hydraulic on a boat trailer for 26ft Sea Ray boat. I had everything including Titan brake actuator, 4 kodiac rotor and caliper conversion kits with bearings, and new lines installed by Thursday evening. Installation was straight forward, everything fit perfectly. One of the calipers was malfunctioning (not releasing). I called customer service and I had a new one within two days, it's now installed and working great!! Great product! Awesome service!!




by:

Quality product at a reasonable price. Worked great- used a "weather pack" connector for a nice sealed connection to the rest of the trailer wiring. Just be sure to carefully check the wire colors (as many noted in the reviews)- they are not standard!


Comments
After a year, product is still like new- weather exposure hasnt caused any issues at all!
Aaron N - 10/02/2017


by:

This trailer harness is exactly what I needed. It is well made and I expect it to last for a lifetime. The wires are all correctly color coded and provide plenty of length. The instructions are provided and are easily understandable. I would recommend this to anyone needing a wiring harness.
Etrailer is the best in customer service.

  • 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,...

  • 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...

  • 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.

  • 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....

  • Troubleshooting Brakes of Logan 3 Horse Trailer Towed by 2015 Silverado 3500 w/ OEM Brake Controller
    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...

  • 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.

  • 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.

  • Trailer Lights & Brakes Are Not Working
    It isn't the breakaway battery as that doesn't factor into the power of any of your lights or your electric brakes. The issue is either with the wiring itself or your 7-way trailer connector. So start by checking out the wiring, specifically the grounds, on your trailer to see if there is any damaged wiring, and that your ground are connected to clean, bare metal surfaces. If that is fine, it is almost certainly the 7-way connector being damaged or corroded and you will need to replace...

  • 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. One of the best ways to preserve the long term functionality...

    If the 7-Way on your trailer is corroded past the point of cleaning it off then it would be best to replace it. You can use either the 7-Way Molded Trailer Wire Connector # H20044 or the etrailer 7-Way Molded Trailer Plug with Junction Box # e99011, which is what I recommend using. 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.
