Video Transcript for Buyers Products Wiring - Wiring Adapters - 337TC1067P Review

Speaker 1: Today we're taking a look at a 6-Way round to 7-Way RV adapter, with the 8" pre-wired cable. This 6-Way round to 7-Way adapter is your solution for converting a 6-Way round pin connector, to a 7-Way connector.It's made of durable plastic, features a built in cover that is spring loaded. That's designed to keep out the elements, and protect the connection points. And then in between the connectors, we have the 8" flexible wire loom, which helps protect the wiring from damage and wear.So again, this basically converts your vehicle's 6-Way round connector to a 7-Way connector. It's constructed of a durable die-cast zinc, here on the 6-Way connector, so that has the nice corrosion resistant design to it. We have the finger tabs there, for an easy grip design.

And on this side, we have the impact resistant 7-Way connector.Mounting hardware not included, but you will notice that it has four pre-drilled holes, right there. Up and down, they're separated on center by an inch and a half, side to side, they're separated on center by 2 1/4".And that's gonna do it of today's look, at the 6-Way round to 7-Way RV adaptor, with a 8" pre-wired cable.

If you have a rig setup for HD towing or trailers, this is a great way to plug into an RV style 7 pin and have everything work as it should. I tow all kinds of trailers and need to be able to switch back and forth between the different style (wiring) of the 7pin connectors.

Fit very well

I used this to convert a Mini Winnie motor home to a Nighthawk Roadmaster 676 Tow Bar and a Jeep Rubicon 4dr with the hm56200 Hopkins Custom Tail Light Wiring Kit for Towed Vehicles. You have to cut off the 4 pin on the jeep wiring kit and wire in the Roadmaster socket that mounts on the front bumper. Follow the wiring diagram and you can't make a mistake. I have to say, this I expected to break out the volt meter and rewire. IT WORKED RIGHT OUT THE BOX. Looking forward to camping and getting the RUBI dirty and wet. Feel free to ask questions the eTrailer guys and Ladies are great. Best customer service. THANK YOU!!!! :)

The 7-way plug is a pill of crap. I will be calling you and returning it!

  • How to Make 6-Way to 4-Way Coiled Adapter for Flat Towing Vehicle
    Since there isn't a 6-way to 4-way coiled adapter like you are looking for you'd have to piece together the kit you are in need of with the part # PK11604 for the 6-way, the part # RM-1064-B for the coiled wire section, and then for the 4-way part # HM48030 and you'd be set.

  • Adapter Needed To Connect A Trailer With A 7-Pin Cable To A 1994 Ford F-250 With A 6-Pin Socket
    Hey Skylar, The Buyers Products 6-Way Round to 7-Way Blade RV Adapter # 337TC1067P should be exactly what you need to connect a trailer with a 7-way to your F-250's 6-pin socket. With a 6-pin connector you just won't have a reverse light pin so the reverse lights on the trailer will not function and neither will any back up cameras tied into the reverse light circuit on the camper. This adapter will still have a pin for your brake controller so you'll be able to activate the brakes on...

  • Trailer Connector Required to Use Curt Echo Brake Controller C51180
    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...

  • Adapter to go From 6-Way on Vehicle to 7-Way on Trailer

  • 6-Way to 7-Way Adapter Recommendation for 1999 Chevy Suburban
    A 6-way trailer wiring connector would normally carry the brake output circuit as long as a brake controller is installed in the vehicle. That said, we do have a 6-way to 7-way adapter part # 337TC1067P which is a simple plug in adapter that will convert your 6-way to a 7-way. If you wanted to just replace the 6-way with a 7-way you'd want the part # PK11898 which comes with wiring, the socket, and a mounting bracket. If you don't have a brake controller installed the best option is the...

  • Need 7-Way to 6-Way Adapter With Center Pin that Carries Brake Output
    There are two ways that 6-ways can be wired like you mentioned. The only difference is that the 12 volt accessory circuit (normally center pin) and brake output circuit (normally 10:00 pin) are swapped. We see this come up quite a bit when people mention that their trailer brakes lock up when connected to a tow vehicle. Since the most common configuration is what I mentioned as "normal" the adapters are in this configuration. What you'd have to do is pull back the plastic loom of the #...

  • How to Convert my 7-way to a 6-way round?
    We have a couple of solutions for you you could simply use an adapter like you mentioned the Buyers Products 6-Way Round to 7-Way Blade RV Adapter with 8" Prewired Cable part # 337TC1067P would do the job but is an adapter so you're adding points of failure there. I instead recommend adding a 7-way female socket on the back of your coach again an idea you had.

  • How to Use Custer Wireless Tow Bar with RV that has 6-Way Round
    The 4-way round connector is very rare and the 6-way round is somewhat common but more rare than 4-way flats and 7-ways so what that means is that we don't have an adapter for your configuration but I have a similar solution. We have a version of the Custer Wireless Tow Bar Light that uses a 7-way blade with the part # LIW-LDTL-7B which we do have adapters for like with the # 337TC1067P which plugs into your 6-way and converts to same connector as the tow bar.

  • Towing a Trailer with a 5-Way Connector with a Vehicle with a 6-Way Connector
    I recommend replacing the boat trailer's 5-way with a 6-way because there aren't any adapters between those two Cut the 5-way off as close to the connector as you can and install part # PK11604 onto the wires. It'll plug right in to your 6-way on your RV. If you sometimes tow the boat with a different vehicle and need to keep its 5-way then you can add a 6-way and have two connectors on it. Use a junction box from the kit # HS381-9000 with part # H20036. You'll need to connect the 5-way...

  • Solution for Needing a 6-Way and 7-Way at Rear of Truck
    Since there isn't a 6-way and 7-way adapter available what you'd need is a 6-way to 7-way adapter like the part # 337TC1067P which would plug into the 7-way. Unless you wanted to wire a 7-way to the current 6-way wiring you have now like with the # A10-7084VP which you'd have to cut the 4-way connector off of.

  • Recommended 6 Pin Round Plug Adapter
    We have several adapters for a 6 pin round plug. It sounds like your 1999 Ford F350 is equipped with a 6 round plug. If so, you can use the adapter # 337TC1067P to go from a 6 pin round to a 7 way. Or you can use # PK12717 to go from a 6 pin round to a 4 flat. If you are looking for an adapter for a trailer with a 6 pin round plug, you can use the # HM47570, which would plug in to a 7 way plug on your truck, and allow you to plug in a trailer end 6 pin round plug.

  • How Would Prodigy P3 Brake Controller Install on 2011 Toyota RAV4
    Along with the Prodigy P3 # 90195 and a 6-way to 7-way adapter # 337TC1067P you would need some additional wiring. Next, for a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied...

    The Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141 that you referenced uses a standard 7-way so any 7-way to 6-way adapter like the # 337TC1067P would work.

  • Can RV with 6-Way Actuate Brakes of Tow Dolly with 7-Way
    A 7-way to 6-way adapter like the part # 337TC1067P does allow the brake output circuit to pass through so if you had a brake controller installed in your RV it would function through the adapter and actuate the dolly brakes. I don't know what RV you have so I don't have an install harness I can recommend for you but I can recommend the Curt Echo part # C51180 which basically just plugs into an active 7-way and once synced to a smart phone is ready to tow.

You will just want to confirm the function/pin configuration on the motorhome socket to verify that the center pin carries the 12V auxiliary power circuit. If you apply a circuit tester like # PTW2992 to this center pin and detect continuous 12V then the adapter will work fine. If you have a small 12V light bulb or a volt meter those can...
