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

Average Customer Rating:  4.7 out of 5 stars   (342 Customer Reviews)


by:

though I'm disappointed with the shipping choice with USPS. etrailer was easy to deal with throughout locating this package. I will order products from your company in the future and choose a better shipping method. Thanks for all your help in this matter.



by:

Nice part, I'm sure anyone would be happy with this harness!



by:

Good strong connector. Built well and installed easily.



by:

Only gave 4 stars because it was a bit confusing. I have a lot of auto wiring experience; from car stereos,amplifiers and all manner of accessories. All of the info on etrailer indicated that the color coding didn't match up. So I went into it disregarding the standard color coding, when in fact it was just as it should be.



by:

Good thick rubber and plug works perfec tly.



by:

Good heavy duty. Perfect replacement.



by:

This is not the first pigtail that I have found that was wired incorrectly.

When you match all the colors up...like yellow to yellow ( left turn) in the box and brown to brown (running light)

The lights don't work correctly....colors have to be mismatched...in order for the ligh/ to preform correctly.
Yellow =left turn....Green = right turn.....Brown = running lights.....White = GND

the pigtail is a nice piece...but 2 of the wires are shaped for standard 7 pin round.in the molded end

This trailer connector does indeed use a different color code for its wires. It is specifically mentioned on the product page. The connector would wire up as follows- White wire is Ground, Red wire is Left TurnBrake lamp, Brown wire is Right TurnBrake lamp, Green is Taillights, Blue is Trailer Brakes, Black is 12-Volt power from battery and Yellow is an auxiliary circuit, frequently used for the reverse lamps.

Still works well, even sitting in the weather it works as intended. It is not used very often but still exposed to the elements.



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.

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.



by:

FAST & EFFICIENT AS ALWAYS



by:

I installed this plug on a trailer and it works fine.



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.

Still working well!



by:

Good quality, fast delivery.



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

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:

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.

Mike M.

2/8/2018

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



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.

All good. Havent used the trailer much tho.



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.

Russell H.

No problems, everything working as it should.



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!

Aaron N.

After a year, product is still like new- weather exposure hasnt caused any issues at all!

Well built. easy to install.

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.

  • How To Wire In The Hopkins 7-Way Molded Trailer Wire Connector
    I've attached a wiring diagram for the 7-Way Molded Trailer Wire Connector # H20044, however there is no guide available to tell us the wire color functions on the trailer so you'll have to test each wire in order to determine its function. If your current plug is still functioning then I recommend connecting to your vehicle and going through each function and testing the wires for power with a circuit tester # PTW2993 at the junction box of the trailer. Having replaced quite a few 7-pole...

  • Parts Needed to Install Electric Brakes On a Tandem Axle Trailer With 3,500 Torque Axles Salt Water
    With your trailer being in an environment where it is exposed to both salt water and fresh water I would highly recommend going with a disc brake setup. There are much fewer components on the brakes to become damaged from the elements with disc brakes. You will need 4 of the DeeMaxx Disc Brake Assemblies # DE89YR with a Hydrastar Electric-Hydraulic Actuator w/ Line Kit # CAR-HBA16-2. You will most likely need a Adapter Module # HBA-CAM for your factory brake controller but be sure to check...

  • Parts Needed To Add Electric Brakes Onto a 3,500LB Dexter Axle Without Brakes
    The Dexter Electric Trailer Brake Kit # 23-26-27 is the correct kit for your Dexter 3,500lb torsion axle studs. This includes both the left and right hand side brakes for one axle. It does not include a hub. I do recommend looking at the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-468-469 instead as the brakes adjust while you drive saving you on having to adjust the breaks as they wear. This also maintains a more constant brake feel with less adjustment required on the vehicle...

  • Adding a Charge Line Circuit To a Trailer With a 4-Way/5-Way Flat Connector
    I recommend moving away from the Adapter 4-Pole to 5-Pole Trailer Wiring Adapter # 47515 and going with a Buyers Products Trailer Connector Adapter # 337TC1474P. The wiring and connectors used on the 4-way harness are not designed to be used with the 20amps of power you will putting on the connector. The 4-way/5-way connector cannot handle the additional strain and it will likely overheat with the amperage and risk causing an electrical fire. With the Buyers Products Trailer Connector...

  • Recommended Parts for Re-Wiring 5-Pole Flat Boat Trailer to Match Truck 7-Way Wiring
    Adapters like # 37385 and # HM47570 are convenient and can work fine for the short-term but for long-term reliability you are really better off replacing the connector on the trailer to a 7-way that matches your truck with no adapters - or their potential problems. Those extra connections can mean more chances for corrosion. You can easily test your truck's 7-way using a circuit tester like # PTW2993. Have a helper activate each function while you apply the tester to the appropriate pins...

  • What Do I Need To Add Electric Brakes To My Carry All Trailer?
    We can definitely get you all the parts needed to add brakes to your trailer, but it is going to be an extensive list since there currently isn't anything on the axle. I did include an article regarding just this kind of situation, but lets get started. First things first, you will need something for brakes to mount onto. This will be done by having the Brake Mounting Flange # 4-34 welded onto the axle. This will need to be done by an experienced welded as the spacing and placement has...

  • Recommended Wiring, Junction Box, And Breakaway Kit For 18-Ft Tandem Flat Bed Trailer
    To re-wire your 18-ft trailer you will need a few things. I recommend installing a junction box like part # PK52248. You can run your trailer connector like part # H20044 to the junction box and use the terminals in the box to run the wiring to the trailer. For 7-way jacketed wire I recommend part # DW04914-1. This is sold by the foot. The junction box will also make it easier to install and use a breakaway kit like part # HM20001. This kit includes a charger and a weather-resistant...

  • Changing Trailer 4-Way Wiring to 7-Way Wiring for Extra Function and Compatible Connector to Truck
    To switch your boat trailer from a 4-way to a 7-way connector, I recommend using the 7-Way Molded Trailer Wire Connector, 6' Long # H20044 along with heat shrink butt connectors # DW05744-5. You will ground the white wire to your trailer frame using # 44-5310A and then connect the running lights, right turn/stop, left turn/stop, and reverse light. To the reverse light (yellow wire on # H20044) you will connect # 16-1-1 wire sold by the foot to lead to your trailer reverse lights that...

  • Parts Needed To Install Electric Drum Brakes On a PWC Trailer With 3,000LB Axle
    Thank you for the pictures Matt. I do see you have the backing plate for the brakes so you are most likely going to have #84 spindle since your axle has a 3,000lb capacity. You can verify this by removing one of your hubs and measuring the landings for the grease seal(1.719"), inner bearing(1.378") and outer bearing(1.063"). If this matches what you have you will want the following parts. Electric Drum Brakes # AKEBRK-35-SA Hub/Drum # AKHD-545-35-G-EZ-K Qty 2 Junction Box # 3430001-JBK...

  • 7-Way Extension for Towing Food Truck with 2003 Ford Expedition
    Thanks for the picture of the trailer wiring connector you have. Based on that you are in need of a 7-way blade extension like the part # C56080 for a 7 foot long extension or part # HM20049 for an 8 foot long extension. Or if you are looking for something shorter you'd want the part # TLW6024 which is 24 inches long.

  • Trailer Brake Lights Do Not Work When Connected have a 96 ranger with seprate turn and brake
    Whenever any type of adapter like # PK12716 is used to mate different types of connectors on the vehicle and trailer, connection problems can develop because of all the extra contact points. The best way to go is to install a new connector on the trailer that directly matches that on the tow vehicle so that you can avoid using an adapter. This is easily done by using a junction box like # 38656 and a new 7-way plug like # H20044. All you need to do is verify the function on each trailer...

  • Can Auxiliary Diesel Tank Fuel Pump Be Powered By Vehicles 7-Way Connector?
    The 12v power circuit in a 7-way connector is typically 40amps, so assuming your fuel pump does not exceed that you can definitely wire it to work in the 7-way connector on your vehicle. You would need 7-Way Molded Trailer Wire Connector, 6' Long # H20044 and heat shrink butt connectors # DW05745-5.

  • 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...

You will need to locate this box and find the wire for the reverse light circuit. This will typically be either the purple wire or yellow wire if your harness does not have a purple wire.
