Very good quality trailer wiring connector. Just be sure you don't simply connect color to color when you splice into trailer wiring. 'FUNCTION' positions may be standardized on the connectors, but color codes are definitely NOT. 343509

Sturdy construction! Much better than using those plastic replacement ends. Only complaint is, the wire colors didn't match standard configurations, a few minutes with a test light and we were in business. 496950


Comments
Thanks for the follow up and reply Andy. We do have the color and functions listed in the specs portion of the product page. But you did exactly as we recommend which is to test for function vs. relying solely on color coding.

So, I have been wiring trailers for a while now. I have been known to wire thing backwards before. So when I got all finished wiring it up and my marker lights were flashing , I thought, I did it again. Re check all the wires. And I have brown for brown, green for green, and yellow for yellow. Well come to find out, nothing is color coded with this pigtail. Cut it all apart and rewire it all. They said they sent me a link for the wiring but I could not find anything about the colors not matching. 609710

There is more than one accepted color code for wiring a 7-way trailer connector. We explain the color code above in the product description.

It is a great relief to get what you order and as fast as it arrived, I could not have expected any better results. The items ordered were good, I would like to see more "MADE IN THE USA", but it is difficult to find. I do like to shop USA. products when practical.. Very good experience ordering from ETRAILER. 327058

Cord is good quality but wire color code doesnt follow the normal trailer light standards. It makes more work for you have to I.D each wire back to trailer plug 479414


Comments
The trailer connector you purchased does indeed use a different color code, which is why we specifically mention this on the product page. The connector would wire up as follows- White wire is Ground, Red wire is Left TurnBrake lamp, Brown wire is Right TurnBrake lamp, Green is Taillights, Blue is Trailer Brakes, Black is 12-Volt power from battery and Yellow is an auxiliary circuit, frequently used for the reverse lamps.

Have had this for a year now. Use it once a week in summer. Connection is still 100%. Great product. 422869


Comments
Its been a year since I got this. The cord has stood the test of time. I dont store it outside so weather isnt the challenge. Its more like the long summer drives. Condition wise it is 98 good, just minor scraps and scratches. No connectivity issue or shorts. I would highly recommend this over others.

I wanted a better wiring harness then what the usual discount national auto parts stores stock. So I went to the web and found this site. Ordered the six foot model (I had been having the existing harness disconnect from the four plug adapter too many times) to give me enough length. Seems very high quality, both the individual wires and the outer protective sheath. Wiring was pretty simple; slight difference in color coding. Just take your time. I used the 3M heat shrink crimp connections. Here's a wiring tip: If you cut the wires in a staggered sequence, instead of all the same length, then when wrapping, you don't end up with a huge bulge where all the crimped connectors are. 414277

I replaced the hydraulic hitch system with this. We have to replace the hydraulic brake drums with self adjusting electric brake drums which we feel will be a better system based on our load. We are hauling a couple of RZR'S so the weight distribution was a concern. All the parts have been good to work with. The attachment nUt sav and lock washers were not with our package. A phone call later and etrailer had them on their way. The sad part is the Postal service has lost them at the delivery point. The videos have been helpful in getting us prepared for the upgrade of our trailer. 373713

Overall a good product, but it could be better. Two main improvements would help a lot. First, color coding the wires to match industry standard instead of the random coloring that is used. Second, the plug is twisted, see picture. 401199

by:

Just what I wanted. 822869

by:

Seems like a quality product just be careful not to use colors as a guide connecting. Brown in this harness is a blinker brake instead of taillights. I think green was taillights instead of turn signals. Otherwise seemed good we will see how it last 818470

Quality of the product was good but wtf. I’ve been wiring trailers and trucks for years. The colors of the wires used to be pretty standard and nothing was standard on this plug. And no diagram so I had to ohm out every pin and wire to fuigure out what went where. I don’t think I’ll buy a molded plug again 809605

Ask the Experts about this Mighty Cord Wiring

  • Would Mighty Cord 7-Way RV-Style Trailer Connector # A10-7W6 Fit 7-Way of 2016 Chevy Silverado 3500
    The standard 7-way trailer connector has not changed at all. The part # A10-7W6 that you referenced would work well with the 7-way you have on your 2016 Chevy Silverado 3500 though. It's possible your old connector or the truck's connector have corrosion or bent pins which would need to be cleaned/straightened.

  • Will Mighty Cord 7-Way RV-Style Trailer Connector Fit Into Ford Factory Connector
    Absolutely, the Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable - Trailer End, part # A10-7W6 has a standard RV style female (trailer) end plug, so it will connect right into the factory 7-way male end connector on your 2011 Ford F-150.

  • Does the Mighty Cord 7-Way RV-Style Trailer Connector Have a Rubber Cord?
    The Mighty Cord 7-Way RV-Style Trailer Connector # A10-7W6 does have a molded rubber construction as well as corrosion-resistant terminals so you can use it with your snowmobile trailer.

  • How To Install Mighty Cord 7-Way RV-Style Trailer Connector With Different Color Tail Light Wires
    In regards to the Mighty Cord 7-Way RV-Style Trailer Connector part # A10-7W6, the most common mistake people make is that they try to match colors for installation which you just can't do. The trailer connector has seven wires, each of which with a certain function. Odds are, the tail lights you are trying to install have different color wires so you need to match function to function, not color to color. I have attached a list of each function for the above trailer connector below. Yellow:...

  • Recommended 7-Way Plug For A 2013 Ford F-150
    The Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable part # A10-7W6 is the trailer side plug. I believe you are looking for a female 7-way plug for your 2013 Ford F-150. The Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable part # A10-7W6 will plug into a 7-way plug on the truck. If you have a factory tow package on the 2013 Ford F-150, you can use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package part # C55774 which will plug into a port under...

  • Why is 10 or 12 Gauge Wire Recommended for Electric Brake Assemblies
    The reason that 10 Gauge # 10-1-1 or 12 Gauge # 12-1-1 wire is recommended for 10" brake assemblies, like part # AKEBRK-35-SA, is because they pull more power than the lights on your trailer. I believe the green wire you are referring to carries the right turn/stop lighting functions as you can see from the attached photo of a trailer side 4-Way. The 14 and 16 gauge wires are too small for the amount of power needing to get to the brake assemblies and they could potentially get too hot,...

  • How to Rewire Vintage Trailer with 7-Way Connector and Parts Needed

  • Circuit Configuration in RV-Type 7-Way Trailer Wiring
    Your photo shows the 7-way trailer wiring setup that we call the RV format. The photo I linked shows an actual trailer plug # A10-7W6 like yours and the circuit arrangement is the same as your photo diagram. For reference, the included article covers all wiring formats in detail. The item you referenced, replacement OEM wiring harness # 118242, is configured in the same way.

  • Troubleshooting Gooseneck Trailer Wiring Connection with Tow Vehicle
    It sounds like you have tested your truck with other trailers and your trailer with other trucks and have found the wiring circuits to connect and function correctly. This tends to suggest that there is just an issue between the two specific connectors. 7-way sockets and plugs like # PK11893 that you referenced and # A10-7W6 will vary slightly in their fit with one another so in some cases one or more circuits in the 7-way, such as the trailer brake circuit for example, may not make good...

  • Replacement for Damaged 7-Way Trailer Connector
    By damaged power cable, I assume you are referring to your trailer's 7-way being severed, and while there likely isn't going to be any electrical damage, you will need to replace the 7-way connector from the trailer. You didn't specify what was severed, but this is the most obvious culprit based on how they connect. For that you would be able to splice in a new connector, depending on the length you need: - 4 feet: 7-Way Molded Trailer Wire Connector # H20043 - 6 feet: Mighty Cord...

  • Recommended Trailer Connector and Wiring to Add 7-Way Trailer Connector to 4-Way for Reverse Lights
    For your reverse lights on your boat trailer, I recommend you start with converting the 4-way you have into a 7-way trailer connector. I recommend the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector # 30717 for this. You will simply plug in your current 4-way and then connect the white wire with the ring terminal to your frame bare metal to metal using # FA1131822. Then you will connect the yellow wire of this adapter to the reverse light power at your tail light on one side of...

  • Electric Brake Compatibility on a Boat Trailer
    Electric brakes on a boat trailer are able to be used without much issue at all. There obviously is an issue with water and electricity, so it is recommended to disconnect the trailer connection when your trailer is being submerged for launch. A few seconds after pulling out of the water, you can connect your wiring without any issues and have the functioning braking system that is easier to maintain. Many boat trailers are moving to electric systems. I do recommend using dielectric...

    The middle pin on a 7-way trailer connector such as the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End # PK12706 is going to be the reverse light circuit. Or you can use the Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable - Trailer End - 6' Long # A10-7W6 and in the case of this connector it will be the yellow wire which you connect your reverse light wiring to.

  • How To Wire Third Brake Light for Truck Cap on Chevy Colorado
    In order to power the third brake light on a truck bed cap you will need the Pacer Performance 3rd Brake Light Logic Module part # PP20-702. The reason you need the module is that the brake/turn signal circuits and trailer lighting circuits are combined so you need to separate the brake/turn signals or else the third brake light would blink when turning. If you didn't want to splice into any wires on the vehicle you could make your own harness with the Mighty Cord 7-Way RV-Style Trailer...

    I did some research and found that your boat is 18-ft 9-inches long. You did not say if your trailer has brakes included which will make a difference when installing the wiring. If you do not have brakes on the trailer and you only need wiring for the lights I recommend part # A35W42B. This is a 35-ft long harness and it has a 4-way flat trailer connector included. This is a wishbone harness that means the running light is split at the connector and the brown running light wire is run...

  • Could EZ Connector Pogo Cable Holder Help with Fifth Wheel Wiring that Breaks around Corners
    The EZ Connector Pogo Trailer Cable Holder # 319-TCP011602 that you referenced can be installed on fifth wheel trailers like what you have but if you are breaking trailer wiring when making sharp turns that indicates to me that you have too short of a wiring harness. I'm not sure what length you have now but we have the part # A10-7W6 which is 6 feet long, # H20046 which is 8 feet long, and # 50-67-005 which is 10 feet long.

  • How to Troubleshoot a Trailer Connector Without Power
    If the trailer connector at the rear of your 1998 Ford F-150 is not receiving power, you will first want to check inside the connector for any dirt or debris. You can use electrical cleaner to clean the connector off, if needed. You will also want to give each of the wires leading into the connector a good wiggle to ensure they are properly attached. If the wires have come loose or the pins inside the connector are corroded, you can replace it using part # HM48190 for 4-way connectors or...

What you need instead is the Mighty Cord 7-Way RV-Style Trailer Connector with Molded Cable - Trailer End # A10-7W6.

  • Towing a Trailer with a 5-Way Using a Truck with 4-Way and 7-Way Connectors
    The easiest way is to use a 7-way to 5-way adapter like part # A75TB. It plugs right in and since you already have all the functions on the 7-way you don't need to make any additional wiring connections. On the trailer side you can add a 7-way like part # A10-7W6. You can either cut off the 5-way and replace it or connect the wires together and have both a 7-way and 5-way to use whichever you need. One final option is to use the 4-way and adapt it using part # 20036. This requires...

  • Replacement 7-Way and Lead Recommendation for Trailer with Melted Wiring
    Since you have some wiring that melted a 7-way with a plug and lead like the part # A10-7W6 would be a great choice. Or to make the install even easier we have a 7-way with a junction box part # e99011 that you can take your old wiring and connect to a box instead of to lose wiring for a much more secure and easier install. I am not totally sure what you mean by the connection bars but the parts I mentioned are sealed connectors.
