Video Transcript for Hopkins Wiring - Wiring Adapters - 37995 Review

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. .

6-Pole Square Trailer Wiring Connector Kit (Car and Trailer Ends) - 37995

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.



by:

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.



by:

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.



by:

Excellent product



by:

Very convenient and quick delivery. Exactly what I ordered. Thx. Kathy



by:

The wiring kit I ordered has been a very hard to find item in the past. Luckily, I found it on etrailer, & it was identical to what my camper came with from the factory! Waiting & delivery was minimal, & I'll gladly order from them again.



by:

It fit the trailer harnes great a little tight but it won't come off . It took a while to. figure out the bike



by:

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



by:

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.



by:

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.

John

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.



by:

Works for my Arctic Fox truck camper.
The
battery feed line is small gauge(14) and if your drawing a lot of power from the truck this wire will easily be overloaded and melt. Run a separate wire if you need more than a few amps out of the truck.



by:

Product was what I ordered. It came when it arrived I used it for its intended purpose. It operated as it should



by:

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.



by:

Delivered in very timely manner. Very easy to install. Works great. Very happy with motorcycle to trailer wiring harness. It cleared up several problems I was having trying to mate the trailer to the motorcycle.



by:

Worked excellant to get the running lights and stop lights working on a motorcycle trike conversion.



by:

This was exactly what I needed for a non-trailer application. I used a pair of these connectors for my antenna rotator wire connections so that I could disconnect them when I was moving the setup. The gauge of the stranded wire is substantial and easy to work with when stripping to make connections. Using it both under screws and soldering to other cables was easy. Color-coding matched the current cables. The two connectors might use a bit of light lubrication to more easy push together and pull apart.



by:

I’ve looked the connector over but haven’t installed it yet. It is a high quality item and I’m sure it will work as designed!



by:

Part came in as described. Was a perfect fit for my needs. Has worked very well. One small problem which we overcame is that the connector is very hard to totally connect and even harder to disconnect when the winter is over. The use of channel lock pliers took care of the problem. Being hard made them more water resistant which was a plus.



by:

Great FAST service and fortunately it was the correct size I needed.. bought the camper used with just pigtail.. Not quite as heavy of wiring I would like as my truck and camper are larger.. #10 or #8 on the power wires would be nice!
But for the price and it serves the tail lights well.. a fair deal... will be buying a decent 7 pin 10' jumper and do it right!



by:

Arrived promptly. Works like a charm. Exactly what I needed.



by:

I bought a motorcycle pull cart to pull behind our Miata. I looked all over Madison to find the right connection pieces. After being told it could not be done, I brought up your web site and found exactly what I needed. Your web site even had a video that I watched and learned from. Now I can travel Route 66 knowing my trailer lights will be working all the way to California and back. Thanks for the great product selection you offer and the efficient way the web site works in the ordering process.



by:

I recently needed a simple trailer plug for a motorcycle. I shopped for the product at a couple of major stores and could not find a six prong connector. I could have kept looking and probably found it but I went to etrailer.com and found it cheaper even with shipping than I could have bought it locally. Thanks etrailer

Dan



by:

As pictured, and a fair price. Arrived quickly and in good condition. I ordered this in error for my application. I will be able to make use of this in the future, however.



by:

This plug was a great fine for me. I needed to rewire the trailer plug on a small pop up camper my daugther had bought. The manufacture wanted $40+shipping for a factory pig tail. The was much cheaper and fit perfect.



by:

Extremely fast shipping,, was in my hands in two days,,, fantastic.

  • Replacement 6-Way Square Connector Recommendations for a Trailer
    For a set of replacement 6-way square connectors you would want the part # 37995. This part number comes with both the trailer and the vehicle side connectors so you would have a spare for your vehicle as well. I attached a review video for you to check out as well.

  • How to Make a 6-Way Square to 4-Way Adapter
    We don't carry an adapter like what you are interested in, but you can pretty easily make one. You would just need a 6-way square like the part # 37995 and then a 4-way like part # HM48145 that you referenced and hardwire he two together. If your trailer happens to be a Jayco you would need to go a different route, let me know if this is the case.

    To convert the 4 pole plug # 118415 on your 2009 Hyundai Santa Fe to a 6 pole that will connect to your trailer, you can use the Hopkins Adapter # 37175 if your trailer uses a round connector, which can simply be plugged into your existing 4-pole connector. If your trailer has a 6-way square connector, you will instead need to use the Hopkins 6-Pole Square Kit # 37995. For this you will actually need to hardwire the harness into your vehicle's 4-pole wires. The kit comes with both connection...

  • Trailer Wiring Adapter for a 2012 Harley Trike To Tow an Escapade Motorcycle Trailer
    I did some research and found that the Escapade trailers use a square 6-Way like # 37995 that you have referenced. From what I could find, the Harley trikes use a round 5-Way. No matter what is on the bike you will need to change one connector or the other. If it is easier to change the trailer side, you will just need to use a trailer side 5-Way that matches the bike 5-Way. If it is round, we have # PK11501. You will need to remove the plug on the trailer and attach the wires from it...

  • Replacing 6-Way Square Connector on Jayco Trailer and Using Adapter # 30104
    The Jayco 6-Way square connector is unique to those trailers and # 37995 wouldn't be a good fit for adapter # 30104. But, it you were to order # 37995 any way you could use it by replacing the 6-Way end on # 30104 with the vehicle side 6-Way that comes with # 37995.

  • Trailer 6-Pin Connector Needed to Match Motorcycle 6-Pin Connector
    Hey Eric, thanks for reaching out! It sounds like you're needing the 6-Pole Square Trailer Wiring Connector Kit (Car and Trailer Ends) # 37995. I normally recommend changing out your connectors for something more standard, but this is the easiest way to make your motorcycle and trailer wiring compatible. Just be sure the connect the wiring by function as opposed to color and you'll be good to go!

  • 7-Way Trailer Connector for a Truck that has a 4-Way Flat Connector
    Are you sure it is a 6-Way and not a 7-Way blade style such as # 37185? The center counts as a pin. I have not heard of a 6-Way blade style connector, not to say that it doesn't exist but I haven't seen one myself. There might also be a way to add a 7-Way to the truck without having to cut or splice anything. If you can tell me the year, make, and model of the truck I can determine if there is a 7-Way that will work other than a hardwire option.

  • Options for Connecting to 6-Way Square Connector of Dutchmen RV
    The Jayco 6-way square connectors use a standard connector but a unique pin out. So what that means is that the # 30104 could work for you but you'd have to cut the wires to match the different pin out which we don't have info on. Or you could cut the 6-way off of your Dutchmen and wire a standard 4-way to it instead like with the # HM48030. The 4-Way vehicle end functions will be oriented in the 4-Way as follows: Exposed pin = ground (white wire on harness) Next pin = running lights...

  • Adding a 4-Way Trailer Connector to the Back of a Honda Goldwing
    The trailer connector on your Honda Goldwing is set up for a trailer with separate circuits meaning brake lights and turn signals are on different circuits. The trailer that you have has combined circuits; the brake lights and turn signals are on the same circuit. So all you will need is a separate to combined converter with a 4-Way flat connector such as # 119178KIT. On it, the white wire is ground, red connects to a brake light wire, brown connects to a tail light wire, yellow connects...

    I do have a solution for you, but unfortunately, we do not carry an adapter that goes from the 6-Way rectangular harness to a current 7-Way harness for your trailer. You will have to do some splicing to get the result you want. What I recommend doing is using a circuit tester, like part # PTW2993, to find out what the function is on each wire. You can either cut the harness off that you currently have, or you can use the Connector Kit # 37995 to access the wiring. You can use Butt Connectors...

    As long as your vehicle is wired properly, Green right turn and stop, yellow left turn and stop, Brown running lights and White ground, then you will have to figure out how the trailer is wired. If the adapter you are talking about was purchased and not hard wired then it could be the 4-way flat to 6-way square adapter for a Jayco RV, and those adapters are wired differently than most other trailers with 6-way connectors and this could be why your lights are not functioning properly.
