Convert your vehicle's 7-way round plug to a 5-way flat with this adapter. Simple plug-and-play installation with no hardwiring needed. Removes easily with built-in finger tabls.
The whole staff at etrailer bent over backwards to make sure I was satisfied with the installation of brakes on my trailer. Have made several purchases from them always satisfied with parts and service. Special credit to Jamie great to deal with. Answered all my questions and was very knowledgeable.
They were extremely helpful when I called to make sure we were ordering the right thing. Worked out great.
Great just what I ordered
Thank all is good
Decent product as usual.
etrailer continues to have great product selection and knowledgeable staff to ensure my needs are met. My boat trailer has a 5 flat plug with the 5th wire unused as I do not have trailer brakes. I had been using an 7-pole to 4-flat adapter and all my light functions worked. However, I was not happy that the spring loaded door did not fully lock in the adapter in place as it partially hit the 5-flat trailer plug. By using the proper adapter (7-pole to 5-flat), the spring loaded door fully locks the adapter in place to ensure it will not fall out when driving down the road. The product was shipped and received very quickly. etrailer will continue to be at the top of my list for such purchases.
Great products, great information on the web site, fast delivery
I will definitely use etrailer in the future
Excellent product options with decent prices. Fast and dependable delivery. Would definitely buy from E-Trailer again when the need arises.
converter was eady to use
This converter does exactly what I needed it to do ---- convert my 5 pin flat connecter on my boat trailer to the 7 pin connector on my new truck. It's keyed so even I can't insert it wrong! Perfect product for my need!

Its great, does exactly what I need. I dont haul the boat much, just to launch at start of year and pull out at end. But the adapter is perfect.
Fits my vehicle perfectively and is a breeze to connect. One year later after several times towing my trailer, the adapter it is still going strong. Still looks brand new.No complaints. I do disconnect it and store it inside my 2015 Surburban when not in use.

The trailer lights connect easily with this adapter. Still looks brand new and works great.
Great product at a great price. Fits perfect. Even has a protrusion that the cover of the truck plug leans against so the adapter cant be pulled out of the plug on my 2013 F150.

Product still working very well.....
etrailer is great. The site is easy to shop and navigate,thay had exactly what I was looking for at a very reasonable price.And as a bonus the adapter I ordered arrived faster than expected.The 7pole to 5pole flat adapter that I ordered works as it should, no more locking up of the brakes on my boat trailer when I am in reverse. I will be placing another order very soon.Thank you etrailer
Super easy, inexpensive. I was planning to add a 5 flat wiring harness for my boat, then I saw this and it works great.

Inexpensive and solid. Worked just right. A year later still working without any issues.
Worked for me, I needed a five pin for the electric solenoid on the brake system for a boat trailer. Worked like a charm

Still in use all is working well
I switched over my trailer wiring from a 4 way to a 5 way and got this adapter for my vehicle connection. Never had an issue after a year of use and I love this. It lets you know if your wiring and lights are working. I definitely recommend this.
The easy afordable way to get the hydraulic brakes bypassed on my boat trailer when shifting in reverse. Saves you all the installation and wiring of a flat 5 pole set up. Only takes a few seconds to install and remove, doesn't take space in the trunk, great idea and product. Won't come off if you forget to remove it.
This is a real must have if you're a Ford owner as the new Fords come with a 4 pin or the 7 pin round connection. So if you own a trailer with back up lights that are normally connected to anti-rollaway brakes, you can't electrically connect you 5 pin trailer to the Ford 4 pin flat connection. So the conversion from 7 pin round to 5 pin flat is the answer.
if you need a five pole like to a boat trailer so that you can back it up with the trucks back up lights are on it works good its the only trailer that has a five prong on it so I just leave it on don't really think about it because it works and its there
Much better than I expected. Delivered very quickly and met my needs to convert a 7 pin round Polack connector to a 5 pin boat trailer wiring harness. High quality molded plastic housing means this will last for a long while. I bought two both a 5 pin and 4 pin conversion. Both were priced right and I found them to be the best value I could find. Interesting my 4 pin unit had a cover for the 4 pin connection yet the 5 pin did not.
Etrailer always have what I need at a good price and ships out fast.
My new truck has a 7 pole socket and a 4 pole flat for OEM trailer wiring. My boat trailer has a 5 pin flat, so this is Just what I needed at a good price. As usual etrailer got it to me promptly. Puged right in and worked with no hassel.
With disc brakes on a trailer, you need this to activate the lock out solenoid so you can back up the trailer. Convenient to use this if you already have a 7 pole round connector on your vehicle.
Once again, outstanding and prompt service by etrailer.com. Although I have not yet used the 7-pole to 5-pin flat adapter I received it within 4 days and it is just as advertised. Always a pleasure doing business with etrailer.com.
