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.

Looks good, I haven't tried it out yet. 364110
Works well with my Ford F-150 trailer light hookup.

You bet, thanks for the feedback. All purchasing experiences with etrailer have proven quite satisfactory. I wish all vendors provided such an experience. Etrailer is my go to place for anything they carry.
Dan M - 08/05/2016Perfect 589854
product was as described in catalog. completely satisfied. 573255
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. 431321
No complaints. It does what I need it to do. Need one? Buy it here at etrailer.com
John T - 09/11/2018This adapter fits perfectly and makes it quick and easy to adapt from 7 pin to 5 pin trailer plugs 366266
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 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! 380735
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.
Mark G - 05/15/2018Excellent! Directions were easy to follow and included photos. Everything needed IS INCLUDED! 400629
Item is exactly as described. Works great with both our 2017 Pilot and 2011 Tahoe. 352702
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
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
1 year later, the adapter continues to work well... no issues at all.
Bill G - 08/30/2017fit exactly as described. 679629
Great adapter, my boat trailer has a reverse lockout that requires the extra pin for the reverse sensor to allow me to backup. 659023
