Very good design and easy to install; best suited for 14 AGW.


Great product! is great to do business with. Responsive and very fast to deliver!

One year later and this is still working great!
Michael - 08/06/2021


Easy for one person to install. Quality product


Worked for me. I used the six wire even though I only hooked up 4 for the toad. The RV 7 blade allowed me to bring a power lead to the toad if I ever need it for charging or power the Aux Brake unit. The bracket could be rotated in any direction and I found the best way was to rotate 90 degrees and install to the base plate. My toad grill made for a tight fit for both break-a-way switch and light connector, but they fit side by side with the addition of an L bracket for the break-a-way. The wiring connections seemed solid and water tight. Wired correct 1st time, No Problems.

Still good after a year of use.
Tom O - 05/25/2014


Looks good will install this over the week end if it’s not too cold


This was an exact replacement for another connector that had been damaged. Simple and easy to change out.


I installed this product on a 2016 Cherokee. I followed the instruction video pretty much exactly. However, I realized it had a tendency to push in and out when plugging in the cable. I zip-tied the bottom of the bracket to the car grill and that stopped the bracket from moving.
Great product. I haven't had any issues with it since installation.


Great service


It was exactly like I expected and etrailer's service was fantastic. I THOUGHT I had ordered it but it never showed up (I probably forgot to push the "enter order" button. Anyway, I called them and spoke to Jesse. He went out of his way to make sure the order had not been entered, then entered it for me and followed up to make sure I got it. Thanks, Jesse!


Easy to hook up, works as shown, perfect for what I needed

Works great
Don S - 03/31/2021


This product was exactly what I needed to complete the wiring connections between the RV and Jeep Wrangler. Comes with easy instructions and mounting hardware.


Very heavy duty, well built. Simple instill, all parts needed & good instructions for wiring

still working great after one year on my toad vehicle.
Walter V - 07/31/2019


I've ordered from etrailer previously and have always gotten good service at good prices. Very satisfied, once again. I also appreciate the videos that etrailer provides as assistance for those of us who always need assistance! I'm sure I'll be back again when I need rv parts.


Perfect for the application used on my ATV and holding up well


Installing was a bit of challenge finding a good place/method.
It has worked fine since installed. My vehicle is a 2019 Chevy Colorado.


Worked as expected!

Easy to install
wires and by using the included bracket, had no problem at all installing it on the front of my TOAD (2012 Ford Fiesta)


Finally found a plug with a cable clamp...most don't have this! As always, eTrailer was easy to deal with, shipped quickly, and had fair prices.


Have ordered a number of products from etrailer over the years and never been let down. Response has always been fast and of great quality.
Thanks etrailer!


At last I now have a solid connection at the towed vehicle connection. Thank You etrailer.


I have made purchases for two different vehicles. Both were used for four wheel down towing. Each time etrailer gave me correct information on the products and promptly shipped and delivered them. Best of all they fit correctly and no surprises. I will use them again.

thank you for touching base with me. All the products seem to be fine.They are in use
Rick I - 05/05/2018


The plug looks to be good quality but the bracket is cheap.


This is a replacement for one I caught on something and broke. It is installed and working great. I have it on my Goldwing trike. It is the right size and works perfect. I love it.


Nice connector, came with everything needed to install.


Fast and friendly service, product was good quality , everything was just as advertised.


Found what I needed easy to order

  • Connecting 6-way Vehicle Side And Trailer Side Wiring
    For your 6-way connection on your tow vehicle and your motorhome, you will want to make sure they match the attached photo. The vehicle side is labeled in the photo as is the trailer side. I gave you views from either side of each adapter. This will give you the standard 6 way wiring so your vehicle and your trailer will be compatible with other 6-way systems.

  • 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.

  • 6-Way Trailer Connector Availability for a 2006 Chevy Silverado
    It sounds like you are looking for a 6-way vehicle-side trailer connector. For that we have the part # HM48420. I attached an install video that shows the connector being installed in a similar 2013 Chevy Silverado as your 2006 model.

  • Replacing 7-Way Trailer Connector with Smaller Connector to Tow a Trailer with Brakes
    A 6-way round trailer connector, like # HM48420, once it's mounted isn't going to be much smaller than a 7-way. If you don't need any functions other than running, brake, and turn lights along with the brake circuit I suggest going with a 5-way flat connector like # HM47900. To put a 5-way on both your tow vehicle and trailer you can use the kit # HM47890 that includes both connectors.

  • 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...

  • Tow Bar Diodes for 2015 GMC Terrain with Sockets and Umbilical Adapter Present
    Based on your pictures it looks like your tow vehicle has a 7-way pin style connector and the wiring you currently have is a coiled 6-way round to 4-way round. Also looks like you have a socket already that could be wired as well. The 7-way round style connector that you have is not a standard RV style blade 7-way. There's no easy way to use what you have since the sockets your RV has aren't standard so your best option would be to replace or add a 6-way round socket like # HM48420 so...

    There are a few different options for you so that the 6-Way Molded Connector with Cable # 50-61-108 is compatible with a connector on your tow vehicle. If you already have a 7-Way connector on your tow vehicle you can simply use the Hopkins Endurance Multi-Tow Trailer Connector Adapter # HM47570 which will convert your 7-Way to a 6-Way with the option to connect a 5-Way or 4-Way without an adapter as well. If you are simply wanting to rewire the connector on your tow vehicle so that it...

  • Availability of Mounting Bracket for Bargman 6-Way Super Sealed Connector with Cable # 50-86-007
    The Bargman 6-Way Super Sealed Connector with Cable that you referenced, part # 50-86-007, includes two integrated mounting tabs, one on either side of the 6-way round connector. No bracket is required, although you do need to supply two screws to attach the connector at the rear of your tow vehicle. I did try a test-fit of this harness with several of the brackets we offer but none will accommodate the size of the cable housing. If you prefer to have your 6-way bracket-mounted you could...

    The Hopkins Heavy-Duty Trailer Coiled Extension - 6-Pole Round, # HM47055, will fit your motor home. 6-Pole round plugs will fit with other 6-Pole round wiring, extensions, and accessories. You will need a plug like the Hopkins Endurance 6-Way Trailer Connector Socket - Vehicle End - Ergonomic Design, # HM48420, installed on your 2003 Chevy Tracker. This plug will accept the HM47055 extension. The # HM48440 will not. You will also need a base plate kit for your 2003 Chevy Tracker. You...

  • Wiring a 2009 Scion xB to Tow an Aspen Trailer with 6-Way Connector and Separate Turn/Brake Lights
    First, you will need to add a 4-Way trailer wiring harness on the 2009 Scion xB. You can use # 118468, that you have referenced. The rest of the installation will require a little hardwiring since trailers towed by passenger vehicles normally have combined stop and turn signals. What you will need to do is cut off the 4-Way plug after installing the wiring harness on the vehicle. This will leave you with a white wire, a brown wire, a green wire, and a yellow wire. You will need to use...

  • What Gauge Wire will Fit Into a Vehicle Side 6-pole Round Trailer Connector
    Both the Hopkins # HM48420 and the Pollack # PK11609 will accept a maximum of 12 gauge wire, so neither will accommodate 10 gauge. To get aux power and ground to your 6-way, you will want to run a length of 12 gauge wire like our 12 Gauge Primary Wire # 12-1-1 or # 12-2-1.

  • Can 6-Way Connector with Separate Brake Light and Turn Signal Circuits Install on 2013 Ford Focus
    A 6-Way round connector, especially one that has separate brake light and turn signal circuits, is rare which is why you can't find one. But I can tell you how to make your own 6-Way with separate brake/turn circuits. First, you could get some 6-Wire jacketed wire, # DW04906-1 sold by the foot, and a 6-Way round vehicle side connector such as # HM48420. Then you would use a circuit tester such as # 40376 to find the functions of the tail light wires on your 2013 Ford Focus. Once you have...

  • Recommended Base Plates and Flat Tow System for 2015 Jeep Wrangler
    For your 2015 Jeep Wrangler to use the Tow Defender # RM-4750, you will need the Roadmaster EZ4 Base Plate Kit - Removable Arms # RM-521448-4. This combination will work well with the Roadmaster Nighthawk All Terrain Tow Bar w/ LED Lights # RM-676. Then you will need a wiring kit for your Jeep. I recommend the portions of the Roadmaster wiring kit # RM-15267 that aren't already integrated into your tow bar. These parts are female spade # RM-300115-00, 3 feet wire loom # 459075-1, 30...
