Video Transcript for Adapter 7-Pole to 6-Pole: The Breakdown

Jeff: Hello everybody, this is Jeff at etrailer.com. Today we're going to take a look at this Hopkins seven way blade to six way round adapter. Now this adapter will plug into your vehicle's side seven way blade socket, and it converts your connector format to a six way round pin type. You can see it has this nice tethered dust cap on it, then when it's not plugged in, you can protect the terminals.Now, one note on this adapter, the center pin is set up as the more common 12 volt hot lead, but it can easily be changed to work with trailers and will have the center pin wired as the brake. And to do that, what you'll first want to do is you'll need a circuit tester to test the pins in your six way connector. Basically just ground the alligator clip to the vehicle chassis, and then touch the test light to the center pin on your six way connector.

If the light and the tester lights up, then that means the center pin is hot so it's wired for 12 volts. So you can use it as-is.If the center pin is for the brakes, it'll only have power when your brake pedal is applied or when the manual brake lever on the brake controller is activated. So if it does work that way, you need to switch it. You can easily do that. What you'll want to do if you need to switch it, all you have to do is switch the blue and the black wires that are inside this adapter.

So what you'll do is basically just remove this tethered dust cap, and then if you'll notice right here, there's two screws here and then two right up here. If you just unscrew all four of those screws, this'll split in half, in the inside you'll be able to see where the black wire is attached to the center pin. And then you also see a blue wire, all you have to do is just switch the black and the blue wire, attach them back down, put your screws in. Go ahead and put your dust cap back on, and just like that you're ready to go. So it's pretty easy to switch between the two.But that should do it for the review on the Hopkins seven way blade to six way round adapter..

We had been having trouble with our other adapters, no brakes or intermittent brakes. This adapter fits better than any of the others ever have, great connection and is holding tight. I will be picking up some more of these. The only downside to me was they came on the value shipping which is rather delayed for us and I would rather pay to get it here more quickly. I was needing it and it was several days getting here. We ship a lot and I know shipping directly with USPS goes faster than that and is not expensive.

It works just like new! No complaints at all. I noticed another review stated theirs is not fitting, sometimes the pins can get a little distorted on the vehicle side and can be easily straightened.

Bought this adapter to use pulling our horse trailer. It's worked great.
Cathy was very helpful when I called with questions prior to purchase.

The trailer light adapter has worked just fine. I only use it periodically, but when I have, done the job!!! Thanks for checking on it!



by:

I unplugged the broken plug-in trailer part from my truck
and attached the new part that I bought from your company. It actually fit in the same holes which I bolted back on. Plugged it back in to my truck, hooked up my horse trailer and all my lights worked!!!! I didn’t replace the male end on the horse trailer and it all matched up perfectly. Very easy to install



by:

One year ago I called etrailer to order parts. The customer service rep was very knowledgeable and helpful. Thank goodness for knowledgeable people. Makes my life easier. I do think etrailer has a good system in place and a desire to excell and be good at what they do. The products still work fine. Thank goodness- since etrailer doesn't do the manufacturing.
Thanks etrailer.



by:

Was easy to change 12v and electric brake wire internally for trailers with the two opposite of each other causing brakes to lock.



by:

Works as designed. It's wired for the six pin round to have the center pin as the aux, and the electric brake on the outer ring, which is fine. I note the advertisement says these two pins can easily be swapped, but there was nothing in the instructions which indicated how that might be done.



by:

Very good product, fit both ends well. the 6 point side that is for a trailer was just a tad loose but alittle electrical tape for extra insurance works fine.



by:

Works great. Does what its supposed to do - converts a 6 pin round plug on a trailer to a 7 pole jack on the truck.



by:

The adapter arrive in record time and worked very well. The web site had useful information that helped in the selection.



by:

Appears to work well adapting a 7 pin motor home to a 6 pin magnetic light system.



by:

Worked great, all lights worked. Want to thank Diana for her help ordering this product and shipping it to us on time for us to go camping.

Thanks again



by:

Love this cause, I just don’t have the time to re- wire the bucket truck so it’s nice to just plug this in an I can hook are chipper up !!!!



by:

This was just the adapter I was looking for but no one had enough information to determine the brake signal wiring for sure - except for etrailer. Their technical information is always way ahead of the others. The price was great as well. Delivery was outstanding. They will get all of my business for trailer supplies.



by:

Bought this in case I might need it one day. Have not used it yet. Seems to be of good quality.

This product worked perfect to upgrade my trailer to my newer model wiring system on my tundra

Good quality product. Easy to change pin configuration. Great replacement for worn out adapter. Received product in just a few days.



by:

The product works fine but... what a great company. An informative website and great followup. All companies could learn something from eTrailer's example. They really care about what I think.

  • 7-Way Trailer Plug Adapter or Compatibility with Lance Slide-In Truck Bed Camper
    Lance does have a proprietary plug, but many customers see a standard 6-way or 7-way round and notice it doesn't fit their factory 7-way as well. I've attached an article to help if you have one of the 7-way or 6-way round connectors which we do have adapters for. If you have a 7-way round, then you will use adapter # 47595. If you have a 6-way plug then you will use adapter # 47549 or # PK12728. If you have the special Lance plug, I recommend replacing it with # A7WCB which would directly...

  • Replacing 6-Way on Trailer With 7-Way Connector
    Since wire color codes are NOT universal, we always recommend wiring by function, rather than wire color. If you look at the Trailer Wiring FAQ article I have linked you to, you can see some diagrams showing the proper way to wire a vehicle and trailer side 7-way trailer connector. If can you open up the existing 6-way connector on your trailer, take the housing apart and look at the terminals the wires attach to. In many cases, they will be labeled like what is shown in the FAQ article....

  • Recommended Parts To Adapt 7-Way Vehicle Connector To 6-Way Trailer Connector.
    Let's start with the vehicle side. If you don't already have trailer connector on your 2008 Toyota Tacoma, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118496. Once you have the 4-way, you can install either a 6-way or a 7-way. Factory tow packages come with a 7-way, but you can install a 6-way and be set for your camper. The Brake Controller 6 and 4 Way Installation Kit, 10 Gauge, # ETBC6 will give you everything you need to convert your 4-way...

  • Electric Trailer Brakes Lock Up When Trailer is Plugged in to Tow Vehicle
    The easiest first step here would be to try the trailer on a different truck, and see if the same problem occurs. If the trailer brakes are free until the trailer is plugged in, I suspect that something is mis wired. I would suggest examine the wiring where the break away system was bypassed and make sure that the 12-volt accessory feed is not connected to the brake wire at some point. Are you by chance using a 7 to 6-way adapter? If so, there are two accepted ways of wiring a 6-way connector....

  • Trailer Brakes Lock Up When Using the 7 Pole to 6 Pole Adapter # 47549
    The reason your brakes are locking up when you use the 7 Pole to 6 Pole Adapter, # 47549, is because there are two ways that 6-way round trailer connectors can be wired, as you may have already discovered. The difference is the pin for the electric brake output and the 12 volt power. It sounds like the 6-way connector on your trailer uses the center pin for the electric brakes. This adapter uses the center pin for 12 volt power. As you have noticed, this will apply 12 volt power to your...

  • Troubleshooting Right Side Turn Signal Not Working On Trailer
    This sounds like a ground problem on the right side. The turn signal not working makes sense because with the brake lights, there is a constant signal coming through which is enough to make the lights illuminate on both sides like they should. But the on/off of a turn signal does not offer enough consistent voltage and makes the problem apparent. On the vehicle, check to see if there is a turn signal fuse for the tow package wiring that may have blown. You can use your owners manual to...

  • Trailer Brake Lights Not Working on a 5th Wheel Trailer
    What it could be is the tow package fuse or relay for the brake lights is blown or otherwise not working properly. You will need to check the vehicle owners manual and/or check the power distribution box lid to find the tow package fuses/relays in question. Add or replace the offending part and test it again. If that was the problem and it blows again then there is a short somewhere, most likely a bad ground which could be where the two connectors come together or at the trailer tail lights.

    Since the passenger side turn signal and brake light wire of your 2018 Chevrolet Silverado 1500's trailer connector is not having power, then I recommend checking that fuse 17 in your engine bay fuse box is installed and is not blown. This is the fuse that powers your passenger side trailer brake light and turn signal. You can use a circuit tester like # PTW2993 to test each side of the fuse to see if power is making it through the fuse. I included a link to a helpful article on trailer...

  • Recommended 5th Wheel to Gooseneck Wiring Adapter on 1999 Ford F-250 & 350 Super Duty w/Factory Plug
    Good news, I can help. Your year and model of Ford truck was made with two styles of connectors when they were being wired in at the factory. This means you will need to look at your factory 7-way under you vehicle and see if the back of the 7-way connector has the round adapter or if it has a molded cable that leads back to a rectangular connector on the drivers frame rail. I've attached an image of the two for you to better see. If you have the factory round connector on the back...

    Hey Saran, thanks for reaching out! For a direct part that works with your setup you'll need the Adapter 4 Pole to 6 Pole and 4 Pole Trailer Wiring Adapter # 37175. While this does work, what I recommend doing is installing the Adapter 4-Pole to 7-Pole and 4-Pole # 37185 and using the Adapter # 47549 to make your trailer 6-Way compatible with the 7-Way on this adapter. Reason being that a 7-Way is way more common of a connection so this will help to "future-proof" your vehicle side of...

  • Horse Trailer Brakes Activate Without Vehicle Brake Pedal
    The '.C' means that there is a trailer connected and isn't an indicator of a problem. Are you by chance using an adapter in the 7-way connector to change it to a 6-way? If you are, there are two common ways to wire that connector. One uses the center pin as the brake output, the other use the center pin as the constant 12-volt power supply to the trailer. If the vehicle is wired one way and the horse trailer the other, it would certainly explain why the brakes immediately apply when the...

  • Why Do the Trailer Brakes Lock Up When 6-Way Connector Is Plugged Into Ford Truck
    A 6-Way round pole connector can be wired one of two ways; with the center pole as the 12 volt hot lead, or as the brake. Having the center pole as the 12 volt hot lead is probably most common. In your case, the 6-Way round connector on your Dodge is probably wired with the center pole as the brake lead. The Ford is probably wired with the center pole for the 12 volt power. When you plug in the connector to your trailer and the center is 12 volt power it is just going to lock up the brakes...

    If you're using the wrong plug to connect your trailer, that might be the issue right there. If you don't have something already, you can use the Adapter 7-Pole to 6-Pole # 47549 to adapt your 6 way trailer to your 7 way truck. If not, this type of error usually happens when there's an issue relating with the blue brake output wire that runs from the brake controller to the 7-Way connector.

  • Hitch and Other Towing Accessories Needed to Tow Pop-Up Camper With 2009 Kia Sedona
    To tow your pop-up, you'll need a hitch, wiring, a ball mount, trailer ball, brake controller and a install kit for the brake controller. The hitch needed will depend on if your Sedona is the EX/LX or the base model. For the LX/EX model, I'd recommend the Curt # C13345. For the base model, go with the Draw-Tite # 75551. For the trailer wiring harness, use the Tow Ready # 118410. For a ball mount, use part # 2752. Your camper should have the necessary ball size stamped into the coupler...

  • Replacement 6-Way Trailer Connector Compatible with Audi Q7 Factory Tow Package
    The Replacement Multi-Tow 6-Way and 4-Way Trailer Connector # 40965 will work the 2016 Audi Q7 as long as you have the factory tow package. Audi does use the US Car Connector on their American models so it will be a plug and play compatibility. Your other option is to use an adapter like # 47549 to utilize the factory 7-way and give you the 6-way needed for your trailer connection. This however does not also give you the 4-way flat, so you'd need a second adapter like # PK12716.

If you think you will need some length for your connection, # HM47083 is an alternative that does the same thing but includes a coiled cable that is 3-feet long when stretched fully while the # 47549 is just the adapter portion without the extension cable. 47549 can be changed to allow a different function - trailer brakes - to be carried on...

You can then use the two photos I have attached for you to make sure the wires are in the correct terminals on the trailer connectors.

  • Do Hopkins Trailer Wiring Adapters # HM47083 and # 47549 Do the Same Thing
    Both of the Hopkins wiring adapters you referenced, parts # HM47083 and # 47549, will plug into a vehicle side 7-way socket and convert that connector format to a 6-way round-pin type. The main difference is that part # HM47083 includes a coiled cable that is 3-feet long when stretched fully while the # 47549 is just the adapter portion without the extension cable. Another difference is pin configuration. Usually 6-way connectors use the center pin for the trailer's 12V power feed. This...

    The best way to check a relay is to use a relay that you know is good and insert it into the suspected relay's spot. The first step would be to determine if the problem exists on the RV or on the trailer. Use a circuit tester like part # PTW2993 on the trailer connector at the rear bumper of the vehicle. Have someone activate the right turn signal, and for a 4-pole trailer connector, test the pin that is fed by the green wire. For a 7-way trailer connector, test the pin in the 3 o'clock...

    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...
