Video Transcript for An In-Depth Look at the Adapter 6-Pole to 7-Pole Trailer Wiring Adapter

Today we're going to review part number 47435. This is the Hopkins 6-pole round to 7-pole blade trailer wiring connector. Now this adapter here will convert your 6-pole round wire connector that's on your tow vehicle to a 7-way blade connectors for trailers. Basically, the thing you need to be aware of that on a 6-pole round, it can be wired in 2 different ways, the center pin can be wired as either a brake output or a 12-volt power. Now this adapter is wired, comes to your wire with the center pin as the 12-volt power. If you do need to reverse it, to use that as the brake output for the center pin you can easily re-pin this adapter. Basically, what you would do is there's a screw here and a screw here, just loosen those screws and then you can slide the wire and pop it out and then just re-pin the blue and the black wires, that's all you'd have to do and that would change it over.

That should do it for the review on part number 47435, the Hopkins 6-Pole Round to 7-Pole Blade Trailer Wiring Adapter. .

This is exactly what I needed, to make my trailer lights work with one of my trucks. It works like a charm!



by:

I was needing a trailer wiring adapter for my 2001 Dodge 1 ton with DewEze bale bed which has a 6 pin round electrical plug and my PJ trailer has a 6 pin flat plugin connector. I could not find one locally and nobody had any knowledge about these. I found etailer website but needed help figuring out what adapter I needed, Jameson C replied to my email with information I needed. Placed my order and received adapter in 3 days. Plugged it into truck and trailer and it works great. Thanks Jameson C and etrailer. Very good customer service. Good price and received quickly. Will definitely be a repeat customer.



by:

Excellent solution to transition without having to install new connection. Huge Savings. Bookmarked etrailer.com for all my trailer shopping needs. Super fast delivery. 5 Stars



by:

I got this to hook to back my RV. Plugged six way into RV plug and its still there. The other end hooks to trailer. I have owned this plug before. The place where little screw is in six way will crack just like those 6 way plugs always do. The RV is inside so that should help. I don't plan on unplugging it from RV unless I sell the RV. Left outside the place little screw is will crack. Might put electric tape around the end but it likely will not fit into female end then. Watch how hard you pull on the six way. That screw is very weak spot. The little screws inside do rust and then you need new plug and rewired to work. Oh this plug works good but it has that weak end.

by:

This adapter really made my trailer light project easy. Thanks for selling these.



by:

I t seemed like this was the perfect solution for connecting the 6 pole on our 1994 Jeep Grand Cherokee to our two horse trailer (7 blade); but when we hooked it up the left turn signal did nothing and the right turn signal set off the flashers.
Turning the flashers on in the Jeep also turned on the flashers; the running lights and brake lights worked ok.
I switched some of the wires but nothing seemed to change.
I'd like to put a 7 blade connector on the Jeep but can't get the existing 6 pole connector off, and even if I'm able I don't know how to tell which wire is for which function. I'm guessing the Jeep wiring is not standard?
I think it's time to turn to a local shop in hopes they can get us working.



by:

Great place, always have what I need.



by:

Looked extensively for this rather special combination 6-pole on truck to 7-blade on trailer connector. Contacted a dozen RV dealers and trailer rental places. Parts people went thru their catalogs. No luck. I spent 4 minutes online with etrailer and had identified and ordered the item. It arrived in my PO Box 5 days later. Works perfectly!



by:

Works as it should, I purchased for my dad who's truck is set up with a 6 prong plug for his older gooseneck horse trailer. An now he can use my new gooseneck flat deck trailer, without us rewiring everything.



by:

I received this 6 pole to 7 pole adapter as a quick fix to a new vehicle we had wired to tow behind our motorhome. Thinking the new vehicle would be set up as our previous vehicle, I learned after the install a 7 pole electrical cord was provided which obviously didn't match our 6 pole setup on the motorhome. A quick search led me to e-trailer.com for what I needed and the quick turn around on shipping allowed us to leave for Florida on time.



by:

This worked perfectly. I've owned for about a year and it makes it handy when pulling a trailer equipped with a 7 pin harness and I'm plugging into my 6 pin in my bed. Great product! Handy!



by:

As advertised. I have one truck with a rv plug and one with a six way so the adaptor allows me to hook either trailer to either truck.

working as advertised, great purchase



by:

Good quality and works great. I've only used it a couple times but have had no problem with it. I don't have it mounted and I do wish it didn't have a mounting bracket so it would take up less room in my tool box.



by:

It works perfectly. I also ordered the mounting bracket for the frame and the mounting bracket for the unit. it all was very easy to assemble. I think the wireing could have been a couple inches longer to compensate for the orginal mounting bracket being wider than the acutal plug in. over all it is a good investment. It save a lot of headaches.



by:

I bought this 99 F-250 for a ranch ride. It only had an old style 6 round plug in. After researching how much it takes to rewire for the 7 flat ( time and money), I decided against it. After a few weeks of trying to find an adapter, I came across etrailer and for less than a tenth of rewiring cost I'm ready to go!!



by:

The wiring between the plugs is too short to be much use. I will need to rewire in order to mount the recepticle to the vehicle or hitch.



by:

The cable could be a little longer. Had difficulty when I tried to mount along side existing outlet. Had to leave it loose and use only when towing trailer that required the different receptacle.



by:

Got right adapter on first try, thanks to your find the right adapter feature on your site.

Great, no problemsee at all



by:

quality made. works fine. my application was a bit complicated as I have separate turn / brake lites. had to modify the 7 pin making the reverse lights the brake lites. You guys are fabulous. Keep up the great work. web site extremely helpful.



by:

I am pleased with the two items that I ordered. Instead of having to change out my outdated plug, I was able to find adapters for my various trailers instead.



by:

Trailer wiring adapter was exactly like description. Great service. Excellent transaction...thanks



by:

It's just what I need! The small boat trailer I have had a 7 blade female connector, but the truck I have to tow it has a 6 pin male plug. The adapter will work beautifully!



by:

Excellent product, simply plug-in and go with no swapping of wires or chasing connections. All trailer functions worked straight out of the box.

  • Mounting Bracket for an Adapter 6 Pole to 7 Pole Trailer Wiring Adapter # 47435
    You will need a mounting bracket, like # 18138, to mount the adapter # 47435. The bracket comes with the hardware to attach the adapter to it and to attach the bracket to the truck using self-tapping screws included with the bracket.

  • Adapter To Connect to 6-Pole Round Connector To a 7-Pole Trailer Connection
    The Adapter 6-Pole to 7-Pole Trailer Wiring Adapter # 47435 will plug into a 6 round connector on your truck and then convert it to the larger more common 7-pole connector. While the connector is round the terminals inside are mostly blade connectors. If your 7-way connector uses round terminals in the connector you will also need the Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin # PK12727 to get to the 7-pole pin connection.

  • Options for 7-Way to 6-Way Adapter
    The Hopkins 6 Pole to 7 Pole Adapter, # 47435, does have a pin for the brake output for a brake controller. This adapter will work for your set up as long as the center pin of the 6-way plug on your RV is for 12v power and the pin in the 10 o clock position is for the brakes. You can verify this using a circuit tester like part # 3808. If the center pin on your 6-way plug is wired for brakes and the pin in the 10 o clock position is for 12v power, then you can still make an adapter using...

    You will be able to use the 6 To 7-Way Adapter, part # 47435, to match the RV and trailer plugs, and you will also need to run a Blue brake controller output wire from the brake controller to the rear trailer connector. However there is another way to connect your trailer wiring that would eliminate the need for the # 47435 adapter. What you can do, is check to see if there is a 4-way connector connected to your 6-way. If there is not a 4-way connected to the 6-Way, you can just cut the...

  • 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 # PTW2993, 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...

    You could indeed use an adapter like the Hopkins 6-way to 7-way adapter, part # 47435. Keep in mind, there are two accepted ways of wiring a 6-way trailer connector. One uses the center pin as the 12-v feed, the other uses the center pin as the output circuit for the trailer brake controller. The adapter is set up for center pin 12-v feed, but if your existing 6-way is wired the opposite, you can re-pin it as shown in the linked video. I've also linked to a video that explains how the...

    The Curt Echo Brake Controller # C51180 does need an RV-style 7-way blade-type connector like # PK11893 in order to function. If your camper trailer has a 6-way socket on the rear now you can replace this easily with a 7-way using part # PK12-707E which has screw terminals for easy connection. Although there are wiring adapters to convert a 6-way to a 7-way, such as # 337TC1067P and # 47435, these add an additional connection where is never good in terms of reliability. The Curt Echo...

This adapter also has an integrated 4-pole connector. There are two accepted methods of wiring a 6-way connector, one uses the center pin as the brake output circuit, the other uses the center pin as the 12-volt lead for accessory power. This adapter can be wired either way. To see a diagram showing how a 6-way connector is wired, click on...

Depending on how the wiring is routed on the trailer this could be easy or difficult. The other possibility is to use a separate 12 volt battery and touch each wire to the positive terminal and see what lights up or powers on.

  • Adapting a 6-Way to a 7-Way on a Winnebago View to Tow a Trailer with Electric Brakes
    There are a couple of things you can do. First, you could convert the vehicle side connector to a 7-Way by using # 47435, which is just an adapter. This is going to be the easiest way to be able to use the 7-Way on the trailer without having to hardwire anything new on the vehicle. The other thing you can do is cut off the 7-Way connector on the trailer and install a 6-Way to match the vehicle. This is more work and is not necessary. Because the 6-Way connector you have now has a brake...

  • Using 6-Way Round to 7-Way Adapter and Trailer Lights Flash when Brake Pedal is Released
    On a 6-Way round trailer connector the brake lights and turn signals should already be combined on the same circuit, one for each side of the trailer. So it would not matter if the RV had separate turn signals and brake lights. That is unless someone wired one in and didn't know that trailers use combined brake lights and turn signals. Also, if the hazards are turned on then the brake/turn signals on the trailer will just flash. Use a circuit tester such as # PTW2993 to test the functions...

It is possible that the adapter you're using is causing the issue with your lights since 6-ways can be wired in two different ways. It may also be that there is a bad ground connection either on the vehicle's harness or on the trailer's harness. A weak ground can cause all sorts of...
