Video Transcript for Bargman Wiring 54-77-003 Review

Today we're going to be reviewing part number 54-77-003. This is the Trailer End 7-Way Connector from Bargman. You can see here that it's made from a durable ABS plastic construction. One of the great features about this particular connector, is it has the finger tabs right here. That's going to make disconnecting very simple and easy. This white piece here is a plastic insert that's designed to tighten up over the wires, which is going to secure the wires, but it's also going to help keep out any dirt or grime from entering the socket. The way that you would connect your wires, is you'll need to undo the set screw here.

That's going to allow the face to pop out of the socket and you'll need to loosen up the two screws back here to fit all the wires through. Feed those through, you're going to connect it to the back of the socket. Once you have this removed by undoing that set screws, it's going to expose some connection points here on the back of the face. Make your connections and then secure it back in place, tighten down the set screw, tighten up these two screws to close that plastic insert to keep anything out of the socket and the connection points. The overall length measuring from end to end, that's going to give us a measurement of about 3-/12 inches. Measuring to this point here, if I do measure to that center connector there, it's about 3-3/4 of an inch.

It's got the nice little tab up here so it's going to allow you to know how to enter this into your 7-way socket and then it's going to snap into place for a nice tight, secure connection. That's going to do it for today's review of part number 54-77-003. This is the Trailer End 7-Way Connector from Bargman. .

great product and fast delivery. Although reasonably priced this wasn't the cheapest 7 pin trailer connector, but it has all brass electrical connections and has a screw cinch to keep the wires tightly in place and was definitely the best buy. The on online description (one of the best I have seen) was very clear and helped to select this over others. It shipped quick and got delivered sooner than I expected. Would highly recommend this product and this company. 210535

This connector is of hard plastic rather than the softer rubber. I think it will slide in and out smoother than the other ones. That means the set screw probably will not strip out as quick. 96064

E trailer did a fantastic job. Before order: Technical support / help was excellent. Goal, conversion of a 1998 Floe snowmobile trailer from surge to electric brakes. Problem, due to time and corrosion, I could only supply partial part numbers, spindle diameter. etrailer did a fantastic job, researching, and getting me the correct part numbers, so I could order. Julie did a great job. She was very timely, communicated clearly and honestly, and just “kept me in the loop”. I received the order came on the projected date, complete and undamaged. Excellent. I would highly recommend etrailer, for your part needs. 439114

Product is constructed very well. Instructions were good and the YouTube version very helpful. However, the one thing I would recommend is that ignore the blue, white, etc. reference on the product and match the wiring to the receiving unit on your vehicle. I found an image for a 7 Way trailer connector and followed it. Everything works. I had previously tried to follow the color references on the unit but that did not work. I gave it 5 stars because once you have it wired correctly the unit itself fits the receiver very well and as I said everything works. Not to mention it is at a good price and shipping was prompt. 436052

We purchased these connectors as replacement stock for our numerous trailers as the connectors are always being damaged in the field. etrailer always has a large selection of new/replacement parts available with a very competitive pricing, good quality and quick turn-around and delivery. We have purchased from etrailer in the past and will continue to to buy from them in the future. etrailer Customer Service is always very helpful and always follows up to confirm delivery. 240307

It fits well into the truck receiver. My only concern is being made of plastic, how well will it holdup over time due to UV. Also, I didn't care for the wire lugs. There is no room to fit the wire into the lugs being that the screws are in the center of the lugs. 14 ga wire fit snug in them, but to 12 & 10 ga wires are nearly impossible to fit in. Only the center lug is round with the set screw from the side making it easy to install wire 432750

I thought is plug looked the best of the replaceable RV 7 way flat blade plugs etrailer carried. Overall okay, better than the Pollock plug on my trailer I replaced that had rusted all the terminal connections inside. Don't know if they new one will rust or not but I haven't been impressed with the Pollock brand. Wish the housing was a little more rigid. 149786

As usual the products I ordered arrived when promised and were in good condition. I don't know what more I could ask. I even got a call when there was a question of the quantity I ordered I was called to verify so I would not be sent or charged items I had not ordered. (The order was correct) 152019

Do you have a question about this Wiring?


  • Re-Wiring 7-Way RV Style Trailer Side Wiring Connector
  • I can certainly help you re-wire your trailer-side 7-Way connector. Thanks for the photo of your connector, it helped verify the style connector and which wires you have! The attached wiring diagram will help you in attaching the wires back to your connector. Based on your photo, the only wire you don't have is the Blue wire that would be for the Brake Controller Output/trailer brakes signal. The Green wire should carry the Tail and Running light circuit, Black is 12V power, Yellow is...

  • Plug-And-Play Trailer Connector for 2005 Chevy Silverado
  • A 5 pole round connector is really rare, with the 7-way, 6-way and 4-pole flat being the most common. Most trucks that come with an OEM trailer connector will come with a 7-way. A 6-way is sometimes found on horse trailers, and a 4-pole is the basic connector used for smaller trailers that supplies lighting circuits only. I've edited a photo for you showing an example of the plug and socket (or trailer and vehicle ends) of each of these connectors. I'd recommend fitting your truck out...

  • Compatibility of a Pollak Heavy-Duty 7 Pole Round Pin Trailer Wiring Connector with Blade Connector
  • The Pollak 7-pole round pin part # PK11700 is not compatible with Pollak 7 and 4-pole connector # HM40975 because it has blade style pins. What I recommend is you change your trailer connector to a 7-Way blade connector part # 54-77-003. You will also need a wiring harness like # PK11998 to install the 7/4-Way connector. It plugs into the back of the 4/7-Way. The connector mates with RV-style socket to form a weather tight seal. -Red - Left Turn and Stop - 14 gauge -White - Ground...

  • Can 10 Gauge Wire Fit The Bargman 7-Way Trailer End Connector
  • I pulled one of the Bargman 7-Way Connector, part # 54-77-003 and a piece of 10 gauge wire to see if it would work. Although the 10 gauge wire is tight when inserted next to the post on the back of the connector, I was able to get it to fit and tighten, so it will work just fine for you. I have included a short video that shows the 10 gauge wire being installed on one of the posts at the back of the connector.

  • How to Confirm Trailer Wiring Configuration to Match 2007 Jeep Grand Cherokee
  • Trailer wiring often uses a particular wire color for a particular function, such as a white wire for ground, but there is no absolute rule that this will be the case. For this reason testing with a circuit tester like # 40376 is recommended. In the case of a trailer you can use a spare battery (or your Grand Cherokee battery) to test each trailer circuit to see what light activates with the 12V input power applied. The linked trailer wiring article illustrates the various connector...

  • Compatibility of Bargman # 54-77-003 7-Way Connector With # 50-87-004 Vehicle End Socket
  • You can indeed install the Bargman 7-way connector # 54-77-003 onto the # 50-87-004 Sealed connector. However, there is a connector loop like this that's already constructed, part # 20027. If you're wanting to use this item to install a 7-way connector in your truck bed for a fifth wheel, we offer T-Connectors like # 41157 that would plug inline with the truck wiring harness that feeds the 7-way connector on the bumper. Some of these are vehicle specific, so if you'd be interested in...

  • Replacement 7 Way Connector for Use with 10 Gauge Wiring
  • The Bargman 7-Way Connector, # 54-77-003, can be used to replace your current connector which has 2-10 gauge wires. When connecting the 10 gauge wires, as well as the other wires, you can use a ring terminal like part # DW05705-1 if you prefer.

  • Universal 7-Way Trailer Connector to Use on a Custom Trailer
  • The Bargman 7-Pole, RV-Style Connector # 50-67-008 is a 22 foot long 7-way connector for use on a trailer. It's a universal product that can be used to replace an existing 7-way or added to a newly built trailer. We offer similar products in different lengths. See the attached link for our selection. If you're looking for just the connector without the lead, part # 54-77-003 is what you'll need instead. I've also attached a help article on trailer wiring you might find useful.

  • Can 6-Way on Towed Vehicle be Hardwired to 7-Way Connector on RV
  • The easiest way to connect your towed vehicle to the 7-Way on your RV will be to use a cord like the Blue Ox 7-Wire to 6-Wire Coiled Electrical Cord # BX88206. This will allow you to quickly connect your tow vehicle to your RV by using the included coiled cable that features a 6-Way on one end and a 7-Way on the other. If you would rather hardwire the 6-way wires from the towed vehicle cord to the 7-Way, you can certainly do this. You will just need to make sure that you make the proper...

  • Availability of 7-Way Connector Shorter than 7 Feet
  • I have some options for you, but unfortunately I could not find a 7-Way 5th wheel/gooseneck wiring Connector Loop shorter than the Draw-Tite # 20027. I recommend simply looping up any excess and wrapping a zip tie # DW05727-25 around it to adjust it to a shorter length. If your tow vehicle has a 7-way at the bumper that uses a US-Style car connector, another option is to install a 5th Wheel/Gooseneck Harness in line by using the Draw-Tite # 20110. This will provide you with a 7-way connection...

  • How to Make 7-Way Adapter with 7-Way on Either End
  • What you would have to do is use the part # WG54006-043 you referenced and then wire an additional 7-way plug to the other end like the part # 54-77-003.

  • Does Each Circuit of 54-77-003 Use a Single Pin to Contact Vehicle 7-Way
  • Each of the circuits that the 7-Way Connector # 54-77-003 has makes contact with the vehicle 7-way pins with a single pin. In case you were asking about how the wires connect to the connector check out the attached picture.

  • Female 7-Way Trailer Connector Recommendation for Chevy Silverado
  • The part # 54-77-003 is a male side 7-way connector. If you need the female side connector as well you would want the # HM40975 if your vehicle has the round 7-way socket already present. If you need to hardwire the 7-way you'd need the part # HM40975-11998 instead.
