This was the perfect part to replace my old worn out connector on my boat trailer. Just unplug the old cable and plug in the new! Doesn't get any easier than that. Trailers fast shipping and excellent customer service are a definite plus!

Still working great



by:

Product is great, reasonably priced and an exact replacement for my Ranger trailer. Better still was the etrailer support and customer service. I received an email from William S, not a random customer service email account, who let me know exactly when my order was prepared, shipped, and delivered. Excellent service and if anything would have gone wrong, which it didn't, I believe he and etrailer would be right on top of it and correct the matter quickly. Thanks for the great support and products.



by:

Great replacement for my 2018 Ranger boat. I was surprised when I found a mounting bracket for the plug end which will help reduce the stretching and sagging of the trailer plug harness.



by:

e trailer had the exact replacement for my old connector. I very happy they had it and delivered it in less than a week. Thanks!



by:

I ordered a 7 way pigtail for my Ranger boat trailer and was totally satisfied. I wasn’t sure if the one I ordered was the one I needed so I reached out to e-tralier with my vin # of my trailer and they matched it for me. Thanks for the help and speedy delivery time. Would definitely recommend



by:

EXACT REPLACEMENT - 2015 Ranger Trail tandem axle trailer. 521C. Great quality and informative shipping. E Trailer is always top notch. Highly recommend.



by:

Same as the one from factory on my trailer. Just hope it lasts longer than the other one. Seem to unravel over time . Needs to be made out of different rubber or plastic materials.



by:

Exact fit easy to install on my BASSCAT Trailler, now there half price (was $62) from the last one I bought, as I've had to replace it every two years, they just disintegrate. Made a returned this time and made my own from one of my previous adapters that the exterior disintegrated.



by:

Replaced the one on my Ranger Boats Trailer 521 dual axle. Works great excellent quality easy to install



by:

Although I think this will work for my intended purpose, you really only have about 63" of usable length. The wires may have been cut to 94.5" but that is not the usable length after it is coiled. Can you stretch it to that length, maybe with some added heat? Not easily and with much strain on the plugs at either end.



by:

Tried to order from Boatmate they didn’t answer the phone or email or return a call.
Trailer was smooth as silk



by:

This item was an exact replacement for the original equipment on a Ranger boat trailer. It lasted three years before disintegrating. I hope the one I just purchased as a replacement lasts longer.



by:

Quick service and delivery of proper pa rts



by:

Purchased as a direct replacement for an older version that had degraded in the sun and the wire jacket which provides the coil effect had disintegrated. Easy to replace and works great. Only complaint is the threads on the collar fitting that attaches the cable to the bracket on the trailer side are not long enough. You can only catch a few threads with the plastic nut to tighten the collar on my ram-lin trailer.



by:

Prefect replacement and installed easy,on marine master trailer

  • Replacement for Fulton Jack on 2016 Boatmate Trailer
    Hi David; for a replacement jack I recommend the Trailer Valet JXS Drill Powered Swivel Trailer Jack w/ Footplate # TV64FR. This jack has a 5,000 lb capacity so it will be a lot easier to operate compared tot the Fulton one you have now. You also have the option to use a drill to raise and lower it (changes lift capacity to 1,250 lbs). I'm guessing you want a wheel so you will also need the # TV89FR. As far as the wiring I'm not sure what you currently have on the trailer. If you have...

  • Where Does Sliding Lock of 2019 Triton EZ Loader Trailer Mount on the Tongue?
    The Optronics 7-Pole Blade to 5-Pole Flat Connector Wired Trailer Adapter - Coiled Cable - 94-1/2" Long # A57CCB will work with your trailer wiring. The 5-way on your trailer will have the reverse light power that will on the trailer connection end connect to the reverse lockout solenoid of your coupler. I've attached a photo of the underside of the coupler that has that reverse lockout wire coiled up underneath. This will electrically stop the fluid flow to allow you to back up your...

  • 7-Way Vehicle Connector to 5-Way Flat Trailer Connector Adapter
    Yes, there is an adapter to plug your 5-flat boat trailer connector into your 2016 Ram 2500's 7-Way. It is the Mighty Cord 7-Way RV Style to 5-Way Flat Trailer Connector Adapter item # A10-7275VP. This will provide you with a secure connection so you can connect to your trailer and power your lights and back up solenoid.

  • Replacement Actuator With Electric Lockout for Fulton A60
    What you need is an actuator rated for disc brakes with an electric lockout. I recommend the Demco Hydraulic Brake Actuator # DM62VR.This has a 7,000 lb capacity which is slightly higher than your A60 and fits a 2" ball. It also features the E-Z latch coupler that lets you drop the coupler over the ball to snap in place. The electric lockout will allow you to back up without getting out of your truck. I'm assuming you currently have a 4-way on your trailer so you will also need to change...

  • What 7-Way to 5-Way Adapter do I Need to Tow a Boat Trailer on My 2021 Audi Q5?
    The adapter you need to adapt a 5-way boat trailer to your 7-way on your 2021 Audi Q5 is the 7-Pole Blade to 5-Pole Flat Connector Wired Trailer Adapter - Coiled Cable # A57CCB. If you do not need the cable, you can get the cable-less adapter as well. That is the Adapter 7 Pole to 5 Pole Flat - Molded # A75TB.

  • Will 7-Pole Blade to 5-Pole Flat Connector Work With Utility Trailer With Brakes
    Hi Justin; the # A57CCB is designed to connect your vehicle 7-way to a 5-way on a trailer. The 5-way is for trailers that have lights and an electric lockout on a hydraulic brake actuator. If that is what you have on your trailer and you want to wire it in directly you can cut off the connector and hardwire it. If you have electric brakes you want to use the # WG54006-043 instead which has your standard brake output wire and 12V power on top of the functions for the lights.

  • Available 7-Way to 4-Pole and 5-Pole Wiring Adapters
    Yes, a 4-pole flat type trailer connector can mate with a 5-pole flat. The additional circuit on the 5-pole side would obviously not be connected. But we do have 7-way to 4-pole cord-type wiring adapters too, similar to 7-to-5 adapter # A57CCB, such as # HM47065, and # C57271. We also have plug-style adapters such as # HM47570 that convert a 7-way to 4-, 5- and 6-pole, all in one product. All wiring adapters are shown on the linked page.

  • Parts Needed to Make Custom 7-way to 5-Pole Wiring Harness for Light on Bike Rack
    To complete your wiring with a 7-way cord, taillight converter and 5-pole connector I recommend using a few other similar items to give you a cleaner and potentially more reliable setup. Instead of cutting part # A57CCB you could use coiled 7-way plug/cord # WG54006-043, converter # 118158 and 5-pole vehicle-side connector # HM47900. To make the wire connections you can use butt connectors # DW05744-10.
