Video Transcript for Hopkins 2-Pole Flat Wiring Extension Review and Installation

Hi there, do it yourselfers. Today we're going to be taking a look at Hopkins two wire plug. Our wiring harness comes with a connector on each end. If you look at these, you'll see that the exposed male end on one side has a red wire, and the exposed to male end on the other connector has a white wire. This is so you can cut it in half here and wire off one side onto your trailer, and the other side can wire up onto an accessory, such as our light here, which will allow it to easily disconnect from our trailer.Some of the lights that you can purchase out there already come with one end, but your trailer might not have a connector on it. So you can use this to wire in the appropriate connection that you'll need to plug into those lights, right onto your trailer.

Now there's other uses for it than just your lights here. You could also use this to make any accessory quick connect using this plug. Some examples would be a breakaway switch, because it's good to check your breakaway switch every year and check its functionality. And if you're finding that you're replacing it quite often we'll might as well make it so you can just plug in a new one real fast.You could also use it with other accessories that you may want to take off your trailer and keep them safe, such as maybe a backup camera you got at the back of your trailer. You don't want to leave it on there all the time.

So you just unplug your camera, toss it in the glove box of your truck, and whenever you need it you can just put it right back on the back and plug it in. Now it's easy enough to get wired into place. Our trailer here just has bare wires. We've got our left turn signal and over here we've got our taillight circuit.So what we can do is take our harness here snip it in half. And then we can wire it up.

Now what you want to keep in mind is what you're going to be plugging into it and how it's wired. So for example here you can see that our light already has a connector on it. It has a red wire and a black wire there. The red wire is the stop circuit, or the turn circuit, and the black wire is our taillight circuit. So we want to make sure that when we wire up our connector on this side, that our red wire here is going to plug into the red wire on here and that it's wired to the appropriate circuit.So you can see the wire here is red going to the male, and the wire here is red going to the female.

So they're going to plug in. So we just need to put the red to our turn signal and then our white to our taillight circuit, which is our brown wire here. We'll strip both of those back on both our trailer and on our harness. And then we'll use butt connectors to connect the two together. I highly recommend that you use heat shrink butt connectors to do so, as that will keep out any moisture, ensuring a long lasting connection, and preventing corrosion.Crimp our butt connector to our stop light circuit from the other end of our butt connector. We will crimp on to the stop light circuit for our connector, which is our red wire. And then we'll crimp our other two wires together. Now if you we're doing this on other accessories such as a breakaway switch, those are just a two wire circuit to your breakaway switch, so you could wire this in with either side of that, because your breakaway switch doesn't really matter which side is switch. We'll then heat shrink our butt connectors down.You can now plug in your light or if you have a light like this that didn't come with one, you can wire up your other end that you cut to that light and then plug it in. If you already have a plug that came on your light like ours did here, then you could use this to wire to your trailer on the other side. You do want to keep in mind though that you would need to reverse the wire colors, as you can see here they are opposite. So just you want to keep that in mind if you are going to use it in that situation.Now you want to also keep in mind your lights will likely have a ground wire that you'll have to connect as well, if you're using it for lights. Most of the time those come with a ring terminal pre-attached on those. So I'm going to finish getting our light mounted up and then we'll test it out. Now we've got it all mounted up. I went ahead and plugged our tester in here to make sure everything's working and you can see here that we're all hooked up and up and running. Having a connector added to any of your accessories makes it easy to replace them, so it's particularly useful on your LED lights here because if you do have any malfunction, let's see you back into something, something happens, it gets damaged, we can't replace the bulb, so we're going to have to replace the whole assembly. Just quickly disconnect it and we can get our new one hooked back up without requiring any stripping or crimping, just plugging in the new assembly. And that completes our look at Hopkins two wire plug.

I ordered some wire and electrical parts to rebuild my 16' lawn service trailer. These folks had good prices and everything was in stock, well packed and shipped promptly and for a reasonable fee. These site also has helpful articles on wiring selection, color codes, etc. Very helpful.


Comments
The Hopkins trailer connecter truck side broke in a month. Replaced. Second one broke a couple of months ago. I have an all-metal connector ready to install.Not your fault, but its a crappy design from Hopkins.Thanks for following up. Getting ready to do two more trailers and it was a good reminder to re-visit you guys for the parts.

I found in the past, that Hopkins wiring have always been dependable. I used these particular adapters to hook up auxiliary lighting for a slide in camper on my trailer and also for a hook up for my tow behind sprayer on my garden tractor. Performed great on both.

E trailer did a fantastic job. Before order: Technical support / help was excellent. Goal, conversion of a 1998 Floe snowmobile trailer from surge to electric brakes. Problem, due to time and corrosion, I could only supply partial part numbers, spindle diameter. etrailer did a fantastic job, researching, and getting me the correct part numbers, so I could order. Julie did a great job. She was very timely, communicated clearly and honestly, and just “kept me in the loop”. I received the order came on the projected date, complete and undamaged. Excellent. I would highly recommend etrailer, for your part needs.

I just received the Hopkins two-pole flat wiring extensions that I ordered and I am very pleased with the quality and functionality. It is a standard two-wire connector but these connectors have become increasing hard to find locally and the etrailer price is great and the shipping is reasonable. I ordered several of these connectors to have available for future use.

I was unable to find the exact connector that wanted to replace. This connector seemed to be a good substitute. When it arrived I found it to be too tight to insert and very difficult to disconnect. Since this cable requires frequent connection and disconnection between my motorhome and towed is was not sure if it would be more of a problem than a solution. I called customer service and they were most helpful. Their suggestion to use dielectric grease has helped somewhat. Time will tell if this will be usable. Time will tell.

These Hopkins 12" extensions are great. They arrived today as promised, I had been waiting for them to install a quick disconnect for a Float Charger for my H.D. (got mine done today, couple friends will be done tomorrow). Ironically the mailman came by about the same time as these were delivered according to the "Tracking Program", I went to mailbox and didn't receive them USPS. Package shipped UPSSurepost and they left box in carport - - - Normally all that deliver packages here walk the extra 8 or 10 steps and give ya a knock on the door and leave package by Front Door. Got em anyway. Very Happy with purchase. Mike

The two-pin connectors arrived sooner than expected and were very well packaged. They are being used for hooking up solar panel chargers to outdoor equipment batteries. The connectors really facilitate servicing and maintenance.

These type connectors are getting a bit more difficult to find, and I was glad they were available from e trailer at a great price. Delivery was great and they were well packaged for use. As for my use, I build specialized machines for our industry and these will be used to transfer low voltage from on point to an operator switch. Again great find, great buy, and excellent service as usual.

Ask the Experts about this Hopkins Wiring

  • Can Hopkins 2-Pole Flat Wiring Extension # HM47965 Be Used on 6 Volt Battery
    I have an option for you, but the Hopkins 2-Pole Flat Wiring Extension # HM47965 is made of 16-gauge copper wire, making it inadequate for use on a 6 Volt battery. You'll want to use wire that's 2-gauge or thicker in general for all components 6v or 12v, like the Bulldog Winch Jumper Cable Extension Set - Quick Connect to Quick Connect - 2 Gauge - 15' Long # BDW20219.

  • Parts Needed to Make 2-Pole DC to 12V DC Power Plug Adapter
    I have a solution for you, but we do not offer a 3 ft. 2-pole to 12V DC power plug adapter harness. Your only option is to connect 3 of # HM47965 to reach your required length, or to cut off one plug on one of them and use heat shrink connectors # DW05744-10 to join the wire leads to additional 16-gauge wire such as # 16-1-1. You can then simply hardwire the extension leads to the Rear View Safety Cigarette Lighter Adapter # RVS-505 using the same style connectors mentioned above.

  • Wiring 12V Pump to Tow Vehicle 7-Way Connector
    Assuming that your fuel pump does not draw more power than what the 12V circuit on your 7-Way can handle (typically around 40 amps maximum) then you can indeed connect it directly to the 7-Way in the manner you described. Using the cut 2 pole flat wiring # HM47965 connectors between the wiring is not necessary in terms of function but it will allow you to easily disconnect the pump when it's not in use.

    The ThermaHeat RV Holding Tank Heater Pad # 277-000164 that you referenced needs to be wired to 12V power source for operation. This doesn't necessarily have to be a direct battery connection, but just keep in mind the pad will only work when the particular power source you choose is actually on. You can even use something like the Hopkins Wiring Extension # HM47965 to provide an easy connection you can plug/unplug in a pinch. If you mainly run off AC power it can still be used but...

    We have found that installing the Ultra-Fab Handy Gate Electric Tailgate Lift # UF55-937004 onto a 2015 to 2017 Ford truck requires you to splice into the truck's wiring instead of just plugging into the truck's 7-way trailer connector. The newer Ford trucks won't send power back on the 12 volt pin if it doesn't sense a trailer and the liftgates do not simulate the trailer. Therefore the liftgates will not receive the 12 volt power needed from the truck's 7-way connector. There are...
