Average Customer Rating:  4.8 out of 5 stars   (41 Customer Reviews)

Replace your damaged 6-way round, trailer-end connector with this new one. Durable cable covering resists damage.


Perfect for updating trailer wiring.


I like this style of plug because it is molded and is important in keeping water out of the plug. It is conveint because it has the right colored wires. I have a water tight termination box with studs that it is wired into. Once I damaged the cable so I opened up the terminal box installed eyelet lugs on the spare pigtail, and installed it in a fiew minuets. I keep a spare on hand with lugs on it so if I have an accident I can quickly replace it. I also use these on some of my smaller tow behind equipment. that's why I like this size plug it isn't real bulky.


This is not a molded connector as advertised. It is a replacement 6way connector attached to 8ft of cable, and would cost less to build buying the parts separately! The Bargman #50-61-108 is a true molded connector if that's what you're looking for.


Built a new trailer to haul my bobcat mini track loader, all products purchased from Etrailer worked great, no problems


Product was much better than I expected. Top quality at a reasonable price and fast delivery too. I recommend etrailer to anybody looking for quality, helpful assistance, selection and availability of trailer parts and accessories.
Thanks etrailer!!


The range of products available at etrailer is great. I know I can find anything I need for trailers and towing on their site and at a competitive price. If the item I'm working on is complicated, they have YouTubes available showing how to install the product. I receive the items I order quickly and they are always complete. Their site makes it easy to tell what I need and what I'm getting.


This is a great deal. It will replace a double cable with a molded cable with all wires in one. I am also adding a connector box , which will make a much neater connection rather than splicing the wires. Thanks for all the help.


Exactly what I wanted. Excellent servic e.


We wired it straight to a trailer that was missing this part. Works great.


Excellent customer service! Ordering the products on line was easy and the instruction videos and installation tips were very helpful. I received my order as promised and every thing I ordered was packaged and shipped professionally.

I will definitely return to etrailer for any future purchases. Also the quality of products was excellent and the price was a lot cheaper than anywhere else I shopped, even with shipping cost.


I am happy with a product, looks very neat. Just got it in the mail and going to use it for my small self built rv trailer


Great doing web business eTrailer, fast order delivery and the part was exactly what I needed and ordered ! Thanks , Gary H

  • Troubleshooting Trailer Wiring of Airstream 2017 Flying Cloud 27 FB No Turn Signal Brake Light
    Sounds like the problem is further up the wiring towards the light assemblies. The most common problem is a bad ground for the light assembly so I'd check that first. A lot of times the assemblies ground through the mounting hardware so make sure the light is connected to a clean metal surface. I attached a help article on trailer wiring for more info on this as well.

  • Troubleshooting Trailer Brakes that Lock Up When Connected to Tow Vehicle
    What's going on is that you have the 12 volt accessory circuit and the brake output circuit either shorting out or wired backwards for the trailer wiring connector. If you are using a 6-way connector the common cause for this problem is that there are two ways a 6-way can be wired and the only difference is that the brake output and 12 volt power circuits are swapped.

  • Installation and Fitment of Hopkins 6 Pin Round Connector #H20036
    I went out to the warehouse and pulled a 6-Way Molded Trailer Wire Connector, # H20036, and used a couple of measuring tools designed to measure wiring sizes. All of the wires were 14 gauge. Yes, this will work as a replacement for the standard Hopkins 6 pin round. You will want to cut the wires at the back of the current 6-way connector on your trailer and wire in the Hopkins 6-Way Molded Connector, # H20036. It is important that the wires on the connector are connected to the trailer...

  • 7-Way Recommendation for Trailer to Install Reverse Light Circuit
    Since you have a 7-way on your 2007 Toyota Tundra the best solution is going to be to replace the connector on your trailer with a matching 7-way like part # H20046 and then run the yellow wire of the 7-way to the reverse lights. Whenever possible we try to avoid adapters as they end up being just another component that can potentially cause a problem. The simpler the approach to wiring the better.

  • Troubleshooting Gooseneck Trailer that Brakes Lock Up when Wiring is Connected
    Sounds like you have a 6-way connector since you said gooseneck hitch and that is the most common connector used with them. What is going on is that there is two different ways the 6-ways can be wired. Only difference is that the 12 volt accessory circuit and the brake output circuit are switched. So when you use the wrong wiring setup you end up with the brakes locking up all the time. So basically you just have to switch the two circuits and it'll work fine again.

  • Troubleshooting 6-Way to 7-Way Wiring on Horse Trailer
    Based on the colors you have it sounds like your 6-way wiring is similar to the Hopkins 6-Way Connector with Jacketed Cable - Trailer End - 8' Long # H20036. In this instance the red wire is going to be your brake power. On a typical 7-way the blue wire would be the brake power/brake controller wire. Realistically since there is no wiring standard I would recommend tracing your wire back to the brakes or other functions to make sure you have the wires installed correctly on your 7-way...

  • Adapting 5 Flat on Trailer to 6 Round on Truck
    We do not carry a 6 round to 5 flat adapter, so what you could do instead is cut off the 5 flat on your trailer and use the 6-Way Molded Trailer Wire Connector # H20036. You would need to use a circuit tester such as # 40376 in order to match the trailer's functions with that of the vehicle. I've added a link to a help article on wiring for you to take a look at.

  • Separating Turn and Brake Lights on a Trailer
    Domestic trailers have a 2-wire system where there is a circuit for the running lights and a circuit for the brake lights and turn signals; our trailer connectors are not configured for a separate brake circuit. You can separate those by using Converter # C56196. If you check out the diagram from the instructions of this converter you can see how you will wire it; the green wire is for the right turn and brake, the yellow wire is for the left turn and brake while the white wire is for...

  • How to Wire a 6-Pole Trailer Connector
    I have attached a photo of the common functions for a 6-pole trailer connector for you. If you are looking to replace or add a connector to your vehicle/trailer then you can use part # H20036 for the male (trailer) end and part # HM48420 for the female (vehicle) end. If you will be using existing wires to attach to either of these connectors then it is always a good idea to test them for function using part # ALL640595 first.

  • Can I Power Lights On My Horse Trailer With a Small Battery Installed on Trailer
    Yes, you would be able to install a battery on your horse trailer, and power the lights when the trailer is not connected to the truck. What you will want to do is run the power wire, typically the Black wire, on the trailer connector and connect it to the positive battery terminal. You will want to ground the battery to the trailer frame, and then run the power wires for the lights to the positive battery terminal. Each light assembly should be grounded to a clean metal surface. You...

  • Trailer Wiring Harness with Circuit Protection Recommendation for a 2001 Dodge Dakota
    Splicing in a trailer wiring harness is a pretty common practice even though almost all vehicle manufacturers do not recommend doing so. This is because trailer lights will put an additional load on the tail light circuits that vehicle manufacturers usually do not account for. The more lights a trailer has, the larger the load on the tail light circuits. Standard lighting on a trailer usually consists of two tail lights, two brake lights, two turn signals and two side marker lights. Many...

  • Recommended 6-Pole Trailer End Wiring Plug Connector to Accept 12 Gauge Wire on Trailer
    I would recommend you get the Pollak 6-pole # PK11604 for your trailer connector. This trailer end connector accepts up to 12 gauge wires. You should not be trimming the 12 gauge wires to fit into a 14 gauge plug because the power draw will still be more than the plug is rated for and may limit the power or not work properly. What you will want to do is snip off past where you stripped the wire and then wire up this Pollak connector # PK11604. This will be the best solution for you...

  • Will the Hopkins 6-Way Trailer Connector Work With the Hopkins Endurance 6-Way Socket
    The Hopkins Trailer Connector, # H20036, will work with the Hopkins Endurance 6-Way Socket, # HM48420. One thing to keep in mind when using these two items is to make sure that you wire the Endurance socket so that it is compatible with the 6-way trailer connector. There are two different ways to wire a 6-way trailer connector and the main difference is the location of the brake control wire and the 12 volt power wire. I have attached a photo that shows how you should wire the Endurance...

  • Availability of Trailer Side 6-Way with 20 Foot Lead
    The longest 6-Way connector and wiring lead combo we have avalable is the Hopkins 6-Way Connector with Jacketed Cable # H20036. This harness features a cable length of 8 feet. In order to extend the harness to the 20 feet you are needing, you will just need to wire in the Jacketed 6-Wire from Deka, part # DW04906-1. This jacketed wire is sold by the foot, so you can get exactly the length you are needing for your trailer. I have attached a short video demonstration on the Hopkins 6-Way,...

  • Solution for Activating 5th Reverse Light Circuit on Trailer's Wiring
    The fifth circuit that the Adapter 7 pole to 5 pole part # A75TB carries is the reverse light circuit. So as long as the 7-way on your tow vehicle has this circuit activated the reverse light circuit would then carry over to the trailer's wiring. Replacing the 5-way on your trailer with a 7-way like the part # H20036 would also be an option worth considering. I don't like to recommend adapters for long term use as it's basically just another wiring connection which is where most wiring...

  • 7-Way Recommendation for Installing on Older Horse Trailer
    I have a great solution for you, but the part # 50-87-009 is the vehicle side trailer connector. It is a 7-way like you need though so you are on the right track. For your trailer you would want the part # H20036 which would go well with the part # 50-87-009 if you installed it on your tow vehicle. I attached a help article that has trailer wiring diagrams as well.

  • Installing 7-Way Trailer Plug on Trailer with Electric Brakes
    I recommend the Hopkins 7-way molded trailer wire connector # H20044. It will measure 6-feet long and provide you the functions required for your electric brakes. If you prefer a longer connector, the same item is available in an 8 foot length as part # H20036 or an 11 foot length as part # HM20048. Please note that the color codes on these molded connectors are different from those usually found on a trailer. The wiring code is on each of the product pages. If you don't have some already,...

  • Troubleshooting Trailer Brakes and Brake and Turn Lights Not Functioning With 7- to 6-Way Adpater
    First, I recommend testing the 6-pin round connector on your Ford F-350 to ensure it is functioning correctly. You can use a circuit tester, like # 40376, to test the functions at each pin. The pin at the 12 o'clock position should have constant signal for the taillights and running lights. The pin at the 2 o'clock position is for the ground wire. The 5 o'clock position is for left turn and stop. The 7 o'clock pin is for right turn and stop. The 10 o'clock pin is for the brake controller...

  • Replacing a 6-Way Trailer Connector on a Rockwood XL 1280 Pop Up Trailer
    It sounds to me like the previous owner did not wire his home made trailer connector properly. If the trailer came with a 6-way connector, then that means there are two additional wires coming from the 6-way connector for the trailer brakes and, most likely, an auxiliary power source. If you are not worried about supplying power to the trailer brakes or auxiliary power source, then I would first recommend checking your local laws to see if brakes are required on your trailer.

  • How To Wire A 6-Pole Vehicle Connector To Charge And Maintain The Auxiliary Battery On A Trailer
    To wire the center pole on your vehicles 6-Way connector to charge or maintain the battery on your trailer you will want to run a length of 10 gauge wire, # 10-1-1, with an inline 40 amp circuit breaker, # PK54540, from the center pole of the 6-Way vehicle connector to the positive side of your vehicles battery. Using a inline fuse on the trailer side while not required, would protect your vehicle from any problems associated with the wire or the battery on the trailer side. The center...

  • Replacement 6-Way Round Trailer Side Connector for 1978 Reddale Camper
    If I had to guess I would say the 2 wires together are for the running lights, one for each side of the trailer. The brake lights must be on the same circuits as the turn signals which is common for trailers. It sounds like you know what the basic lighting functions are for the wires that you have. You can always double check using a circuit tester such as # PTW2992 or power each wire and see what activates using a separate 12 volt battery. If you just want a 6-Way round that you can attach...

  • Adapting a 7-Way on a 2003 Chevy Silverado to a 6-Way Round Trailer Connector on Big Tex Trailer
    If your 2003 Chevy Silverado has a 7-Way connector I recommend keeping the 7-Way that you have # 50-67-005, and using it to replace the 6-Way on the trailer. A 6-Way is not nearly as common as a 7-Way blade style connector. You just have to determine the functions of the wires on the trailer and wire them to the new 7-Way accordingly. The functions on the 7-Way should be as follows: White Wire = Ground Red Wire = Left Turn and Brake Brown Wire = Right Turn and Brake Green Wire = Tail...
