Video Transcript for Hopkins Wiring - Wiring Adapters - 47435 Review

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. .

Adapter 6-Pole to 7-Pole Trailer Wiring Adapter - 47435

Average Customer Rating:  4.8 out of 5 stars   (115 Customer Reviews)


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:

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



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.

still connected I hardly use RV its for sell



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:

The wiring adapter that I bought for my new camper worked perfectly with my pickup wiring. Didn't have to do anything but plug it in and go.

Working perfectly!



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:

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:

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

Great, no problemsee at all



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:

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:

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:

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:

Convenient adapter



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:

Very pleased. After being told by a local auto parts store that there was "no such" adapter...... I was excited to find this adapter on etrailer. Due to time constraints, I needed an immediate fix...no time to take my truck into the shop and have them wire a 7 pole hook-up.



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:

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:

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:

Thank you very much,exactly what I need ed

Great



by:

This is just the item I was looking for to convert the 6-wire on my older pickup to accommodate the 7-wire hookup on a dump trailer I recently acquired. Save me a lot of trouble and suits my needs . . .



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.



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:

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.

  • Brake Controller and Install Harness Recommendation for a 2011 Four Winds on a Ford F53 Chassis
    You are in luck, the Ford F-53 chassis has a plug and play harness way up behind the dash that will allow a brake controller harness like part # 3034-P to install a brake controller like the Prodigy P2 Brake Controller part # 90885 that is our best selling controller because of how easy it is to setup and how easy it is to use. As long as your tow dolly has the same 6 pin plug that your RV has you wouldn't need an adapter. If you do need a 6-way to 7-way adapter part # 47435 would do the trick.

  • How to Adapt a 6-Way Vehicle-Side Trailer Connector to a 7-Way
    Since your vehicle already has a working 6-way connector for your trailer that uses electric brakes, you will not need to install any additional fuses or relays in order to change to a 7-way connector. The simplest and most cost-effective option is to use an adapter to convert your 6-way to a 7-way. You will need to test the wire functions on your existing 6-way since these connectors can be wired in two different ways: center pin as brake signal, or center pin as 12V power. You can use...

  • Hooking Up My RV w/ 6-Way Connector To Trailer w/ 7-Way Connector
    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...

  • Recommended 6-Pole To 7-Way Trailer Connector For 1999 Ford F-250 Super Duty
    If you have a 6-pole connector on your 1999 F-250 I recommend using the Hopkins 6-Pole to 7-Pole Trailer Wiring Adapter, part # 47435. You simply plug this into your 6-pole when you want to tow the gooseneck and you have a 7-way connector to use. The 7th pin is likely a reverse light circuit that likely is not used so you should be good to go. If you have a 7-way on your truck and need a 6-pole to tow a trailer then you can use part # HM47570.

  • Swapping Pins of Hopkins 6 Way to 7 Way Adapter #47435 to Prevent Brake Lock Up
    The easiest way to rewire the Adapter part # 47435 to prevent the brakes from locking up would be to do it on the 6-way side since that side comes apart a bit easier. So to do that remove the set screw at the base of the 6-way and at the tip of it so that you can access the pins by sliding the housing down onto the wire harness and swap the pins that are in the center pin and the 2:00 position. The orientation of "up" of the 6-way will be with the alignment slot on top.

  • Which Terminal of Trailer Junction Box Controls Trailer Brakes
    Assuming the person who wired up your junction box followed the correct labelling of the box the terminal that has the "blue" written above it would be the one that controls the trailer brakes. If they are locking up a lot that would indicate that one of the other circuits is shorting out to it which is commonly caused by cut or exposed wiring. If they are locked up all the time it's probably a short between that circuit and the 12 volt accessory circuit which is the terminal labeled black.

  • Can Curt C51180 Echo Wireless Brake Controller Be Used with 6-Way to 7-Way Adapter
    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...

    To convert the 6-Pole on your 2002 Foretravel to a 7-Pole, you could use the Hopkins Trailer Wiring Adapter, # 47435, that you mentioned. Since you are not finding power on the 6-way, most likely the wires for the 12V power and brake controller output have not been run so you are correct, these will need to be run. For wiring you can use our Wiring Kit for Electric Brake Controllers, # 5506. The 12V power wire will connect to the positive side of the battery and brake controller output...

    There is an adapter you can use to go from the 6-Way round on your truck to the 7-Way blade on the trailer. It is adapter # 47435. On this adapter the center pin for the 6-Way side is wired as the 12 volt circuit. If the 6-Way is the same on your truck then you do not have to do anything. If the center pin on your truck is for output to the trailer brakes then you would need to swap the 12 volt and brake wires on the adapter. Honestly, it would be better to just replace the 6-Way on the...

Then with the 7 pole installed you can use the Pollak adapter # PK12716 for your 7 Pole to 4 Way Connector when needed.

  • Options for Going from a 6-Way to a 7-Way on a Tow Vehicle
    I attached a picture of what a 6-way normally looks like. Sometimes people get 6-ways and 7-ways confused if they don't count the center pin. The simplest way to go from a 6-way to a 7-way is to use the adapter part # 47435. You would most likely want the mounting bracket part # 18138 as well. If you prefer you can permanently wire a 7-way connector, using part # PK11898. This includes a wiring harness, 7-way connector, mounting bracket and required hardware.

    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 # PTW2979. 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...

    It is very likely that your 6-way is not wired for the 6-Pole to 7-Pole Trailer Wiring Adapter # 47435. Trailer wiring with 6-way connectors can have two ways the brake and hot are wired, so it is likely the 12V hot and brake output wires are not in the correct locations, which is easy to switch. This adapter is made for the 12v power to be the center pin of your 6-way and the pin in the 10 o'clock position for the brakes. You can verify this using a circuit tester like part # PTW2993....

You will have to do some splicing to get the result you want. What I recommend doing is using a circuit tester, like part # PTW2993, to find out what the function is on each wire. You can either cut the harness off that you currently have, or you can use the Connector Kit # 37995 to access the wiring. You can use Butt Connectors...
