I haven't used the connector but my initial thoughts are that it's built solid, doesn't feel cheaply made. The only thing I see that might potentially be an issue is that there is no tension on the pins when plugged in to the connector on my truck. Not sure if this is normal or if I got a lemon. 379838

This purchase was my second from e_trailer. Both tomes the experience was vert good and rhe products delivered on time and of good quality Lloud 688083

I love this thing! The best part is the cable length. I was needing to either splice into the trailer's wiring and extend it or create a foot long extension. This did it for me! I am going to show it to our local trailer manufacturer. 652342

Great trailer connector, plenty log enough to hook up any connection you have got. Can't beat the price 652133

very well built product. Much better than you can buy in local stores 601166

Very nice product. Great Quality and Very Fast Shipping. 576552

This is just what we need, a sturdy 7 to 5 pole adapter that is long enough to connect to the wiring of our boat trailer. In addition, we received it promptly. 558994

Great adapter 500284

This is a somewhat unusual and hard to find item at most stores selling automotive trailer wiring accessories and harnesses. I purchased a new 4X4 pickup which has the 7-blade connector to the left side of the license plate holder on the rear bumper step. Previously, I had my 7-blade connector immediately adjacent to my receiver housing on the underside of my rear bumper. And, with the higher profile of the 4X4, I now use a 3 1/2" drop drawbar to mount my 2" ball. This new arrangement puts my boat trailer harness extended to it's maximum, with minimal room for wide, short turns over a small distance, or backing up at sharp angles. Enter this Optronics adapter, which adds another 18" to the pigtail side of my trailer wiring, and provides only a single connection between the two five way flat connectors. Molded in 7-blade plug and solid jacketed 12Ga wiring with the five way flat female connector molded in on the other side. This adapter works like a champ and looks great! 493086

This adapter has been in use about 150 days over the past year and performs without any problems. Connections remain tight and waterproof, and we have certainly found ourselves having to tow in some extremely wet weather conditions last year. Although this is an economy-rated product compared to some others you have available, I could not see needing a better adapter/extension than this one by Optronics.

Easy to order on line, and got it on ti me. 443155

A57WB Made hooking a boat trailer to my suburban a piece of cake! E trailer should update their Web site putting the A57WB up front showing how easy a connection can be. 392236

Very good quality and works as designed. 391505

I needed this to hook up my new 5 pin trailer with surge brakes to my truck with a 7 pin plug. Not only does it allow me to back up and release the brakes but my trailer assist feature now works with the back up camera. 386281

After a year its working just fine. Very happy with this purchase.

I was unable to find this wiring harness at any of the local automotive or farm supply stores. It is exactly what I needed for my boat trailer and the product works great. Once I ordered the product, it arrived at my house within days, which is great service on top of a solid product. 252614

Still very happy with the wire harness. Thanks for following up this isextraordinary customer service ...

This was the perfect harness between my pickup and the different trailers we tow. 249993

Makes using a different hitch a breeze. As sometimes you need more drop and setback which shortens the harness. 247077

Very pleased with product well made

This extension was exactly what I needed to hook up my Ranger Bass Boat to other's trucks where the original trailer lights are not long enough. Great product and price. 139856

The 7-way blade to 5 pin adapter is terrific. The quality of the connector's sockets and ground pin are excellent. Likewise, the outer jacket and molded connectors make the adapter nearly impervious to environmental induced deterioration. 136215

Plug and play,,,,,what more can you ask for? 126613
