Are you a boating enthusiast who needs a reliable connection between your vehicle and boat trailer? The Optronics 7-Pole Blade to 5-Pole Flat Connector is your perfect solution. It efficiently converts your vehicle's 7-pole wiring connection to the 5-pole flat pin setup required for trailers equipped with hydraulic brakes and reverse light power.

Exact replacement for Ranger Trailer wiring harness. Timely delivery and easy install.Quality appears to be good after 1 year. Original lasted 8 years--time will tell.
Direct replacement for a 2017 Triton 20 TRX Patriot Trailer.
Fits perfect. The hardest part is getting off the small locknuts the factory used on the cable brackets. etrailer service is excellent.

Do you have any tricks that worked for you on the locknuts? Might be able to save someone reading your review a lot of effort... :)

Exact replacement for my 2012 EZLoader boat trailer including the mounting pieces. Photo shows my original was disintegrating. I’m very happy with this exact replacement.
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!

Fabulous
Fit perfectly. Love the holes in connector for zip ties since the trailer tongue is a sway system.
Worked perfect for my 2016 Ranger 519C double axle trailer

My trailer plug was working great till I forgot to plug it in on my last trip and had to replace it. I called and customer service had a new one sent to the resort we were staying at in 3 days so I was able to replace it before we had to travel back home. Awesome!!! customer service. Thank you!!!
I called into customer service while driving down the road needing help to reorder a part I previously purchased and Sarah helped me find my part and ship it over night to the resort we’re staying at so I’m able to fix my trailer before we leave. The tracking, the service and most of all Sarah that helped me were absolutely awesome!!!! Thank you for everything!!!!
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.

The equipment I purchased is still in excellent condition and works as it should.
Works great for connecting/converting from flat plug to round plug. However, the insulation is very stiff and would need to be softer and more flexible. Just like the last one I had, the outer insulation cracked. This one seems like it will do the same.
perfect replacement for my bass boat tr ailer
Excellent customer service! Thanks
Thank you! It was a quick connect and working perfectly just in time for my LBAA tournament
Perfect replacement on Ranger boat trai ler.
Got turned on to this in a forum as a replacement for a Ranger bass boat trailer with a folding tongue. Awesome...saved a pile of money. One year in, still in perfect shape, coil is still tight.
I actually returned the long one (94-1/2") for the shorter one. The shorter one was a perfect fit for my Ranger bass boat. Very happy. Installation was easy. I would definitely purchase again if needed.

Glad it worked well for you, Keith. :) So you like to fish? Do you do any professional competitions or just for fun? My newest brother in law is semi pro, I believe. Never knew how big the fishing world is!
Everything worked great and delivered fast I will order here again thanks for the good service
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.
Was the wrong part, Opronics gave me the part number to give you, have to send it back, the one on right is wrong
Just ehat i expected. Arrived two days early too. I have never been disappointed dealing with your company
It's exactly what they say it is.
Quick and easy process to order and great service
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!
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.
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.
