Today we're going to review part number A75TB. This is the Optronics 7-Way Blade to 5-Way Flat Adapter. Now, this adapter will convert your tow vehicle's 7-way blade connector right here into a 5-way flat pin connector. This model is a nice molded 1 piece unit, has the connector on each end, and also molded in as this nice, easy grip handle, which you can use to plug it in and also to remove it. As you can see here, it has the blade design for the 7-way and then right here for your trailer to hook into, it has the 5-way flat. Now, you can also install a 4-way flat on here. You just don't use that end pin.
That end pin is used in a 5-way. It gives you the reverse light circuit. Because on a trailer that uses a 5-way, it needs that reverse light circuit to activate the reverse lockout on the surge brakes on the trailer. on the 4-pin, it's not required so you just plug a 4-pin in by using the ground and you just don't use this end pin. That should do it for the review on part number A75TB. The Optronics 7-Way Blade to 5-Way Flat Adapter.

Super easy, inexpensive. I was planning to add a 5 flat wiring harness for my boat, then I saw this and it works great. 111191
Inexpensive and solid. Worked just right. A year later still working without any issues.

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. 289360

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. 364220

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. 314391

Always pleased with products from etrailer.com. Great customer service & follow up if needed. Very helpful web site with merchandise descriptions & photos from different angles. Have ordered from etrailer for my job needs in the past, but have since retired. Will continue to order for my personal needs. A job well done! Thanks for your help. 260601

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. 283298
by: Dan F08/31/2010
Works as advertised I needed a simple bare bones adapter, and this works perfectly for my needs. Can't beat the price. Product seems well made. I haven't had it long enough to comment on reliability. Customer service at etrailder was fantastic - I ordered two by mistake and they corrected it with one phone call. 3401

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 389862

Product arrived sooner than expected. Unable to find this locally so this was a pleasant surprise to have the process go so quickly and easily on line. Still 3' of snow and 3' of ice on the lakes so it will be awhile before we get to use the boat. 178871

It works just like it should. I had originally a 4 pin harness on my 2011 pathfinder but change to a factory 7 pin. I bought this 5 pin adapter to use with my boat trailer witch just need a connection to turn off the brakes when I reverse. 78305
