These people are a LIFE SAVER yall! I have been looking for this adapter for 2 months and finally found it (didnt think about looking for it online)! The package arrived on the exact day the site said it would and provided me updated tracking info its whole journey here! My lights FINALLY work on my trailer and I am so happy! These people also respond to you very quickly and provide awesome info aswell! I cant say enough good things about these people! I wish I could give them more stars!!

Product is still working perfectly! Even after being left out in the rain, being yanked out by accident, and surviving mud after being ped in it!

Worked well for installation on my toe car.


Shipping was messed up because I put in the incorrect Zip code. They quickly reshipped my item to me. Thank you for the help!


Good product and excellent customer service. I had a small issue with the Adapter and the support group at eTrailer was extremely helpful. They will be my go-to site as I continue my restoration project.


I ordered wiring for my 2008 highlander trailer brake and blinker hook up. When I opened the box with all my parts everything was there. I needed a small wire loop and it was there as well. Your [installation] video showed me step by step instructions on how to install all the parts. Certainly no problems.
Very satisfied with your service.


Good products and excellent time to del ivery.


Harness fit perfectly. Easy installation, the video was spot on. Wiring is hidden nicely.


Very satisfied with the 4-way flat to 6- way round adapter, it was exactly what I needed and the service, cost and quality of the product was outstanding.

  • Solution for Connectiong 4-Way Flat on Vehicle to 6-Way Round on Camper
    In order to connect the 4-Way flat connector on your truck to the 6-Way round connector on your camper, you can use the Mighty Cord Trailer Connector Adapter # A10-6034VP. This adapter will plug right into the 4-Way on the truck and provide a 6-Way round on the other end. The additional white wire is for ground and will need to be attached to a clean, bare metal surface. The other two wires form the adapter can simply be tied off and left unused, assuming you only need to power the basic...

  • 4 Way Flat to 6 Round Adapter for Honda Goldwing
    Since you have separate wiring for turn signals and brake lights, you would first need to install Converter # RM-732. From there you would be able to use the Adapter - 4-Way Flat to 6-Way Round # A10-6034VP that you referenced. I have added a link to a video review of the converter, as well as a video showing an installation for you to take a look at. The instructions for this converter have also been attached for you.

  • Parts Needed to Install 6-Way on 1996 Jeep Cherokee
    You can add a 6-way to your 1996 Jeep Cherokee, though there isn't a plug-in 6-way, you would need to wire it in. First you would need to add a 4-way (which also has to be hardwired in as there isn't a plug-in option for a 4-way on a '96 Cherokee), and then a 6-way adapter. The 4-way will plug into the adapter and the 6-way will be wired to your battery and the brake controller wire. So, exactly what you need will be the following: - Tail Light Converter Hardwire Kit w/ 4-Pole Connector...

  • Is a Battery Charger Needed with the Stay-in Play Duo Supplemental Braking System?
    On your 2018 Jeep Wrangler, I am thrilled with the parts you ordered. The Mighty Cord Trailer Connector Adapter - 4-Way Flat to 6-Way Round - 12" Harness # A10-6034VP will give you the 12V charge line from your 7-way on your motorhome to give a maintenance charge to your Jeep battery. Although a charge line isn't required, the SMI Stay-IN-Play DUO Supplemental Braking System # SM99251 does use that vehicle battery, so I do recommend connecting it. You can simply connect the 12V wire of...

    The Mighty Cord Trailer Connector Adapter part # A10-7084VP would work for you if the trailer has a 7-way trailer connector. 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. Please keep in mind that both 6 and 7-way trailer connectors are used for trailers with brakes. If your trailer has brakes then the better option for you would be the Universal Installation Kit for Trailer...

  • Parts Needed to Re-Wire Motorcycle Trailer Wiring Harness For Trailer without Brakes
    The only way to know what wires correspond to which functions on the trailer will be to test them, and the license plate light will be attached to the running light circuit and won't have its' own wire-it's more likely that the red wire you're seeing corresponds to a reverse light circuit. With that said, since the trailer doesn't have brakes you're probably best just wiring it up with a 4 way wiring harness like the Wesbar 4-Way Flat Trailer Wiring Harness - 20' Long # 002220; this won't...

  • Using Hopkins Tow Bar Wiring on 2011 Jeep Wrangler That Needs Charge Wire From RV
    You can use the Hopkins tow bar light kit part # HM56200 on your 2011 Jeep Wrangler as it's a confirmed fit, but the 4-way ends of this and the # A10-6034VP don't match as they are both male 4-ways. So what you could do is cut off the 4-way of either side and install the # HM48190 in place of it and you'd be able to make the connectors as needed. For a coiled extension to adapt the 7-way or your RV to the 6-way of the adapter you'd then want the # RM-1676-7 which will carry the charge...

  • Easiest Way to Install 6-Way Trailer Connector on 2011 Honda Ridgeline
    The easiest way to install 6-way wiring on your 2011 Honda Ridgeline will be to start with a 7-way that's custom fit for your vehicle like the Tekonsha part # 118253 and then use a 7-way to 6-way adapter # HM47570 to match the 6-way on your trailer.

  • How to Attach a Toad with a 4-Way to a Motorhome with a 7-Way
    The Blue Ox EZ Light Wiring Harness part BX88314 has a male 4-way trailer connector. The Mighty Cord Trailer Connector Adapter part # A10-6034VP and the Tow Ready Trailer Connector Adapter part # 30637 also both have male 4-way trailer connectors so they will not plug directly into each other. The best option for you is to use the RoadMaster 7-Wire to 6-Wire Flexo-Coil Kit part # RM-146-7 or the RoadMaster 6-Wire Trailer Connector part # RM-910030-7 if you already have the adapter. You...

For your wiring, I recommend the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 along with 6 way connector # A10-6034VP to create a system similar to the # RM-15267 but utilizes the wiring in your tow bar instead of the coiled wire.
