Today we're going to review part number 37995, this is the Hopkins 6-Pole Square Trailer Wiring Connector Kit. You can see it has the square design 6-Pole on both connectors. It includes the male end, the male end is what would go on the trailer and includes the female end, 6-square end, which will go on to the vehicle. Basically the pigtail wires on each, they use an 18 gauge size wire. The length, give you an idea of the length on these, got a 12 inch ruler and basically you can see that you're about 12 inches in length on each one. Now basically what you would do is this one here, with the female end, this would connect to the vehicle, the tow vehicle, so you'd wire this in with the pigtail wires. This end, with the male ends, would go to the trailer, and again you'd wire those in.
Then basically all you would have to do is push that together, just like that, and you would have the six way connector. That should do it for the review on part number 37995, the Hopkins 6-Pole Square Trailer Wiring Connector Kit. .
Delivered quickly exactly as advertised. No problems.
Quick response to order and delivered on time. Can't ask for much more. Thanks
The product came quickly and was exactly as advertised.
recieved in good shape and worked great for my snow plow lights thks
Good products at a good price, web site was easy to navigate, shipping to my address was very expediant. Very satisfied with overall purchase
I odered several items so I could use my camper trailer with my new truck including a connector kit, a 7 blade connector, and a ball mount and ball. i recieved them fairly quickly all in all and in good shape. The items were all excellent quality,well priced and will do the job I need done
The item should come with the dust caps. I had to buy some rubber and make my own.
Bullet-proof connector, if not the most elegant.
Used in my case for custom "adventurization" wiring on my 2007 BMW F800ST motorcycle, now just road tested this late summer - early fall 2017 on a three month, 18,000 mile loop out of Chicago through the Arctic & Pacific Northwest, including the Dempster & Dalton Highways.
Had a custom wiring harness that had to be able to be removed in order to get at the engine, hence the need for the connectors.
A few photos should be attached.
Quick, exactly what I ordered
Good quality, has worked very well on my motorcycle trailer. I would do business with these folks without trepidation.
This is a product that I needed for my project, but was not easily found and available. etrailer.com not only had the product, but had it at a great price. Shipping was very fast and free for the amount I ordered. Overall, this was a great shopping experience. I made a bulk order of 16 as I am manufacturing trailers that are towed behind motorcycles. This product gives me the six conductors that I need in a very small package, which is great due to the size of motorcycles compared to cars or trucks. The only thing that could be improved with this product would be if they came with dust caps for each connector, or at least one for the vehicle side to prevent dust and moisture intrusion while the trailer is not in use. Keep up the excellent service and selection.
Prompt shipping, item quality great.
I needed to add a more convenient location to plug and unplug my backup camera on my 2015 Chevy. The camera harness was a 6-wire harness and this 6-way plug was just what I needed. Works perfectly.
Provided a complex wiring adapter at a reasonable price - Thanks
Great Communications! Fast Delivery!!!
EXCELLENT EXCELLENT EXCELLENT!
Exactly what I needed to tidy up my mast wires on my sailboat.
Quick shipping! Thanks
High quality and was delivered in a short period of time.
I have a Coleman popup trailer w/ a 6-wire harness (no brakes). After receiving the Hopkins 6-wire plugs from eTrailer, I was able to create a conversion cable to "jump" my 4-wire tow vehicle plug lead to the 6-wire trailer plug. It works very well and I will be ordering other items from eTrailer.

Product works well and was just what was needed
It fit the trailer harnes great a little tight but it won't come off . It took a while to. figure out the bike
This product replaces several of types of connectors, e.g., cinch-jones and other 6 wire types. It will be used to connect model railroad show modules. I was looking for a reasonably rapid insertion and disconnect and good conductivity. Power is low power DC, so the wire is more than adequate. I also needed a reasonable drop so as not to strain the terminal strip (barrier) connection. These, I believe, will work well. I hope this helps.

The connector sets I purchased are for inter modular connection on a mobile model railroad. They are working very well. I would hope you might make a connector with more pins, e.g., 8 or possibly 10. I realize the trailer application requires only 6, but the ledger ones might find other applications.
Did not use this as a trailer connector. I had to have a way to plug and unplug another device. This worked perfectly. The wires were long enough to stagger the splices and allow for a smaller diameter splice. Overall an excellent product.

The device I used this on is now installed permanently and no longer need to plug and unplug for relocation., The connector worked perfectly and never showed any signs of corrosion on the connectors even though it was exposed to the elements.
Item wasn't going to work. Would have to pay return shipping. May have to sell on Ebay to try to get some of my money back. etrailer should provide a return label.
I had great difficulty finding this 6-pin "Square" connector elsewhere. I was pleased that etrailer had it and the price was excellent. Delivery was prompt and the part was as advertised.
My only complaint is that the wiring "color code" did not match what I expected from the existing connector on my camper and other wiring diagrams that I had seen. This caused some minor problems initially. Though, I was able to work through it.
I'd certainly use etrailer again for similar part needs.
