Video Transcript for Mighty Cord Wiring - Wiring Adapters - A10-7084VP Review

Today we're going to take a look at the Mighty Cord 4 way flat to a 7 way blade adapter plug. This vehicle end connector will convert any 4 way flat vehicle end plug on your vehicle to this 7- way blade outlet. Basically by plugging this into the 4 way and then connecting the 4 remaining wires to your vehicle. The wires have about a 12-inch long wire lead to them. Once this is connected it will supply this 7 way blade RV connection at the back of your vehicle. The 7 way plug is constructed of a durable plastic, has a nice spring loaded lid to it that when you do open it up and push in your 7 way, you'll notice this little safety latch right here at the top.

That will actually lock the 7 way into here to keep it from vibrating out. Basically when you go to install this what you would do is again plug this into the vehicle's 4 way connector on the vehicle. You have 4 wires left. The white wire, this will need to be grounded to a clean metal surface. The yellow wire, that will run to your reverse light circuit. The blue wire, this will go to the brake output signal of your brake controller.

Then the black wire is your 12-volt power wire, and that'll have to go get connected to the positive side of your battery and run it through a 40 amp circuit breaker. Once that's all connected, then you have a 7 way to use at the back of your vehicle. That should do it for the review on the Mighty Cord 4 way flat to 7 way blade adapter plug.

The order was exactly what I wanted, and was sent out on the same day that I ordered it. etrailer.com is my place to go whenever I need anything for my trailer needs. Thank you guys for a great service! 547116

Product arrived via snail mail. Product did not work upon arrival. After examination determined the ground wire was not connected at the factory. Once wire was stripped and properly connected it did work. Poor quality control at the factory. 564939

I have installed the connector on my Cadillac XT5. I had the 4 plug connector already installed with a blue wire for un-locking the solonoid on the brakes then I installed all wires to match the colors of the 5 & 7 pole. I cut out a hole in the plastic bumper cover and installed the connector with four screws. You could make a new product like this one for the Cadillac XT5 connectors for all boat trailers, this is an easy hook up to the XT5, SRX, and other GM cars. I now use the round type 5-7 pole connector for my boat trailer to lock out the brakes when backing up my trailer. 485431

I boat a boat that came with a trailer that had the 7 way round trailer plug, which of course doesn't work with my 4-way flat plug on my Jeep that I use with my other boat. So, I went by the big [trailer rental] store in town to buy an adapter. However they only had adapters that assumed the round plug was on your vehicle and the 4-way flat was on the trailer and I had the exact opposite problem. So, I went to [big online retailer] where I usually can find most anything and they didn't have an adapter either. A Google search found etrailer.com and they had exactly what I needed. I ordered it and had it a few days later. I was a little apprehensive when I hooked it all up, but it works flawlessly! Now I can easily hookup either boat and I avoided having a second connection installed or modifying one of the trailer plugs. I'm very satisfied with a solution that cost much less than either of my alternatives! 488404

I ordered this product for my 97 Chevy 1500 Pickup. I use it to haul a two horse trailer made in 2007 with new plug adapter. I am female and know absolutely nothing about vehicle/trailer wiring. Hooked it up, everything worked great. Did not have to change a thing. The 97 Chevy is my farm truck and is not used very often. Did not have to touch a thing, plugged right in and went on down the road. Fast shipping. 274942

I have an older truck with simpler connector and no trailer brake controls, and a newer truck for the robust brake connector. After extensive internet searching for an adapter, I again came to etrailer.com and ordered/received a robust part that works great. 303466

I think this will work nicely for what I have in mind. My plan is to relocate my car hauler from my home in Arizona to my home in California. The trailer weighs in at 2,000 pounds and my 2010 explorer has a tow rating of 3,500 pounds. The car hauler has electric trailer brakes on it that I will not need when I haul it empty. So I bought this adapter which will allow me to use all the light functions without the trailer brakes. This will save on fuel costs for the big truck to stay at home this time. Thank you for all you do! 541750

Do you have a question about this Wiring?


  • Recommended 4-Way Trailer Wiring Harness for 2014 Honda Odyssey Touring with 7-Way Adapter
  • For just the 4 way and the adapter for your 2014 Honda Odyssey Touring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56378 which will install behind the driver's side trim panel in the rear cargo area. You will install the 10-amp mini fuse and two 7.5-amp mini fuses in the rear fuse panel. I've attached the installation details to assist. Then for your 7-way plug with only the 4-way functions, you only need the Mighty Cord Trailer Connector...

  • Wiring for Curt Echo Mobile Wireless Brake Controller and Adding Electric Brakes to a Trailer
  • The Curt Echo Brake Controller part # C51180 is a great choice because of its convenient and simple installation. The 7-way connector that you mention part # A10-7084VP pugs into the 4-way connector you purchased part # C56217. The white wire from the 7-way plug needs to be grounded to a clean bare metal surface on the vehicle's frame. You are correct, the black wire from the 7-way connector needs to be extended from the plug into the engine cavity and to a 40 amp circuit part # 9510...

  • Recommended Parts to Add 7-Way Trailer Wiring to 2018 Toyota Highlander Hybrid
  • For your 2018 Toyota Highlander, because you already have the 4-way trailer connector and don't want the brake controller wiring, you simply need to add the Mighty Cord Trailer Connector Adapter # A10-7084VP. Installing this adapter means connecting to your current 4-way and then connecting the white ground wire with the ring terminal to a bare metal connection to the frame or frame mounted panel. Then to add the 12V power, you will use wire # 10-1-1 sold by the foot and connect it...

  • Can a Vehicle with a 4-Way Tow a Trailer with a 7-Way
  • Correct, a 4 to 7-way adapter will allow your friend to tow the trailer. The lights will function therefore making it legal to drive but the brakes would not be able to be engaged without a brake controller. The best and most cost effective solution would be to use part # A10-7084VP on the vehicle therefore no alterations will need to be made to the trailer or vehicle. Once you plug the male 4-way on the adapter into the female 4-way on the vehicle, there will be 4 wires remaining....

  • Wiring Mighty Cord 4-Way to 7-Way Adapter on Tow Vehicle
  • The Mighty Cord Trailer Connector Adapter # A10-7084VP referenced in your question is exactly what you need to connect the 4-Way flat on your tow vehicle to the 7-Way on your trailer. After plugging the 4-Way on the adapter to the 4-Way on your vehicle, the only wire that NEEDS to go somewhere is the white ground wire, which you will securely attach to a bare metal surface on the vehicle's frame. The additional black, blue, and yellow wires can be simply taped off if you don't need them....

  • Recommended 7-Way Mounting To Hide Wiring Connections
  • For the Mighty Cord Trailer Connector Adapter # A10-7084VP and your Curt # C13182 trailer hitch, I recommend the 6 and 7-Way Trailer Connector Mounting Box for Round or Square Tube Hitches # 18159 along with some simple zip ties like # 853-3194-02. This will allow you to keep the connections hidden and also keep the wiring on the back side of the hitch or tight under the frame.

  • Can 7-Way to 4-Way Adapter A10-7084VP be Used for Just Trailer Light Function
  • For what you are looking to do the part # A10-7084VP will work just fine. You would plug your vehicle's 4-way into the adaptor's 4-way and then plug straight into the 7-way of your trailer and all of the trailer lights will function. You could tape up the extra wires as they aren't needed or you could cut them off.

  • If you are looking to add a 7-way to your 2018 Subaru Outback in order to utilize a brake controller you will first need to install a 4-way with Wiring Harness with 4-Pole Flat Trailer Connector # 118467 (although there is not a fit for the Sport model of Outback).

If this is the case then you would want to use Mighty Cord Trailer Connector Adapter part # A10-7084VP.

  • To install a brake controller on your 2016 Ford Explorer, if you have the factory 4-flat you will need to hardwire the rest in. I am not certain which brake controller you have specifically but the black wire is generally the power wire and run to the positive post of your battery through a 20- or 30-amp circuit breaker, and you also want to connect the blue wire coming out of the brake controller to the brake wire and the red wire from your controller will be what you connect to the wire...

However, if it has a 6-way trailer connector like you mentioned then you would want to use the Mighty Cord Trailer Connector Adapter part # A10-6034VP instead.

  • 4-Way to 7-Way Adapter Recommendation for 2016 Jeep Wrangler Unlimited
  • 7-Way sockets are a bit bigger and heavier than 4-way sockets so they are mounted to the vehicle so that they don't sag. If the 4-way on your vehicle was longer than typical you could mount the 7-way of the adapter part # A10-7084VP to the trailer frame and have the 4-way portion reach accross. Otherwise mounting the # 37185 is your best option.

  • Converting a Trailer with 7-Way to Vehicle with 4-Way
  • If the vehicle has a 7-way trailer connector and the trailer has a 4-way trailer connector then you can use the Pollak 7 Pole to 4 Way Connector Adapter part # PK12716 to attach them to one another. However, if the vehicle has a 4-way trailer connector and the trailer has a 7-way trailer connector then you can either use an adapter like the Mighty Cord Trailer Connector Adapter part # A10-7084VP or you can just cut off the 7-way on the trailer and install the Hopkins Endurance Quick-Fix...

  • Which Wire of Mighty Cord Trailer Connector Adapter # A10-7084VP Is for Charging Battery
  • The black wire of the 7-way adapter part # A10-7084VP that you referenced is normally the circuit associated with charging a trailer battery. That said the yellow wire could be too as long as you wired up the trailer to match. From the adapter to your vehicle battery you will need to run 10 gauge wire like part # 10-1-1 (sold by the foot) through a breaker like part # 9510.
