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. .

EASY TO ORDER AND PAY FOR GOOD INFO ON SHIPPING A EARLIER THAN INDICATED THE ADAPTOR WORKED FLAWLESSLY

Just the product I needed. Works great! Appreciate the quick response and mailing time.



by:

Wiring adaptor looks well made. Bought it so that a friend with
a different connector could pull my cattle trailer.



by:

Great service, shipped immediately. We were told by the local shops that this adapter was not available and not even made. Thanks Etrailer you had it at a reasonable price.



by:

Works as advertised. Wish it had longer wires between connectors.



by:

I won't bother with local stores. etrailer had what I wanted after local stores said it wasn't available. Postage much cheaper than the gas to drive around and not find it. Nice people at etrailer, great communication, super fast shipping. I will be ordering more from them.



by:

Great email service.The product arrived when promised and was what I ordered. I will used etrailer for future purchases. This adapter allowed me to used a truck as a backup in case the primary truck in out of service.



by:

Found etrailer.com through Google search. Ordering online was quick, secure, and painless...the way an online store should be! Followup email contact about status of my order and tracking info was very helpful. My adapter arrived on time and looks great. Will be trying it out this weekend. etrailer.com is saved as a favorite now!



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:

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.

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:

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:

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:

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!

    To see a couple diagrams that show how the 6-way to 7-way adapter part # 47435 is wired up check out the pictures I attached. The 6-way of this adapter has the center pin as the 12 volt circuit. That is the usual circuit that gets moved around on 6-ways.

    The blue wire is for brake output power to the trailer brakes. One end connects to the brake controller and the other end goes to the pin in the trailer connector on the vehicle side that is for the trailer brakes. The Adapter 6 Pole to 7 Pole Trailer Wiring Adapter, # 47435, would be if your towing vehicle has a 6-Way round pin trailer connector and the trailer has a 7-Way blade style trailer 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.

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.

  • 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...

  • 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...

  • 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...

    Most trailer connectors on vehicles use a standard size for the pins but there are a few out there that do not. That is likely what the issue is. It does not have anything to do with the function of the center pin. The best solution for you is to change the connector on your 1995 Jeep Grand Cherokee to a 7-Way because it is likely that all the adapters will have the same problem. Since your Jeep already has a 6-Way and the wiring is all there you just have to move the wires from the 6-Way...

    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.

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.
