Video Transcript for Hopkins Wiring - Trailer Connectors - HM48192 Review

Today we'll be reviewing part number HM48192. This is the Hopkins Endurance Quick Fix Replacement Four-Way Flat Trailer Connector with LED test lights. The plug is designed to replace a damaged four-way flat trailer end connector in just a few quick, easy steps. All you have to do is cut off the broken plug, insert the existing wires into the new plug. In order to do that, you just need to undo the two screws here that's going to allow the plate to separate. You can bring your wires through the slots in the back, make the connections and then just press the cover on the new plug closed, and that's going to secure the wires in place, so no stripping of the wires is necessary. It's a very easy system to use.

Once you have the cover pressed down over the wires, you can then resecure by tightening up the screws. Here on top it's going to feature LED test lights that are going to confirm that electrical connections have been successfully made. It's got an integrated dust cover that's going to protect the terminals from the elements. Simply just place that over the connection points. This system here is the wire retention plate. That is going to insure a nice, secure installation.

It's also got some nice grip on it. That way you can get a secure hold and it makes it very simple to plug in and unplug the connector from the connection points. This is for use with 18-gauge wires. It can also work with 16-gauge wires. It's going to come with a terminal grease packet as well as the four-way flat trailer connector. That's going to do it for our review of part number HM48192. This is the Hopkins Endurance Quick Fix Replacement Four-Way Flat Trailer Connector with the LED test lights.

The product is excellent. The part was not in stock and took more than a month. This company has everything and more than you need but, the main problem is that you don't get it when you really need it. 650644

The installable male 4-wire male plug is a GREAT product. The LED "pilot" lights are especially helpful - - to "know" the connections are solid and working. We used it to replace the typically molded-in 4-wire flat male connector on our aluminum utility trailer (that we use a-lot). The install was straightforward and easy. The "cap" to cover the connectors is SUPER. I highly recommend this male flat wire connector - - as a replacement to a damaged molded-in connector OR merely as an "upgraded" connector. It was also VERY easily being an etrailer.com customer -- had what I needed at cost-effective price - - a DOUBLE WIN. (DH Akron, OH) 273146

This is perfect. I needed an easy way to change the connector on the trailer I'm working on. It was an old pop up camper with an 8 pin connector mounted on the frame. but I only needed a 4 after rewiring it. So, out with the old and in with the new! Plus it's really easy to connect all the wires. Picture is not of the new connector but of the whole project I'm working on. I've since mounted all the running lights, tail lights etc. 474178

I have a small cargo trailer business. I only use this model of 4-way. It's bulletproof. I change the screws from steel to stainless (8-32) and add a pair to the top set of holes with a couple of acorn nuts. It's solid and well made. As far as e-trailer is concerned the price is right and they shipped it quickly and for a reasonable rate. I will order a few more to keep on the shelf for repairs. 324251



- HM48192
by:

Seems well made but poor design. In order to view the LCDs the recepticle ground wire has to be on the right. 2nd issue is that there is no way to clamp the insulated wire bundle to the new plug (as is typical with replacement 3 pronged 110v plugs) and that pulling on the wires when unpluging the trailer (instead of pulling the plug itself which is the right way, but which doesn’t always happen!) directly stresses the connection and individual wires, leading to early problems. I would not buy again. 553995


Comments
Due to the way that the connector makes contact with the wiring by piercing the wire insulation, this in an item that I would consider best for a temporary fix in an emergency situation. It would not be my recommendation for a permanent repair.

Installed this on my boat trailer to replace (although it was new) plug end that came with the new wiring harness I had to install. I really prefer to see the blinking LED lights when I am getting my boat and trailer ready to roll, along with eyes-on inspection of the lights themselves. Especially when your trailering up after dark (as always seems to be the case). Also the integral attached plug cover is essential in my opinion, keeps the plug prongs dry and keeps from losing it in the dark. 809079

These male and female 4 wire pigtails are advertised as "quick fix" connectors. I use these connectors so that I can make my own pigtails. Sure, you can buy a pre-wired pigtail and add on to it by splicing the wire with butt connectors, however by using the quick fix connectors, you eliminate the need for the butt connectors and an additional possibility of a place to have a problem such as corrosion. The connectors are easy to use, reliable and you do not have to use the conventional 4 flat wire. I have used these connectors with individual wires as well as a round, 4 conductor wire. In addition, these connectors are a newer version with screws to connect the plug together rather than a snap connector. This version also makes them easier to take apart in case of a malfunction. 717001

At almost the one year mark of installation, I hooked up the trailer for a snowmobile trip and the wires pulled out of the plug. Dont know if the internal prongs separated that hold the wires in??? I just spliced into an old molded plug with wires to get going. I do like the plug with the LEDs that tell you a circuit is present so it is a good tester to keep around for that I guess. 599590


Comments
This is a handy item to keep in your toolbox if something should occur while out on the road. Then, once youre back home you can do a permanent fix. This item is really intended as a quick fix in an emergency situation, and not as a permanent repair.

  • Recommended 4-Way Connector for 6-Wire Trailer Wiring
    It sounds like you have something similar to a wishbone wiring harness with 2 running light circuits and then also 2 ground circuits. To replace this, I recommend the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights # HM48192 where you will simply match the current wires to the correct terminal for function. If you want to splice them together prior to the connection, I recommend the Hopkins Endurance 4-Way Flat Trailer Connector - Trailer End -...

  • 16 Gauge Wiring Options for the Hopkins Replacement Endurance 4-Way Trailer Connector
    While it is possible this may work, I did contact Hopkins who confirmed this Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector # HM48192 is designed for use with 16 or 18-gauge, not the 14-gauge of the Wesbar 4-Pole Flat Connector w/ Jacketed Cable # W787274. They did not recommend this approach of stripping wires to make it fit. The Hopkins Endurance Quick-Fix Replacement is not a great long term solution but with the appropriate length of Deka Wire - Jacketed...

  • Trailer Plug is a 4-Way Flat But there are 6 Wires
    It sounds like your trailer had a wishbone harness and/or could have multiple ground wires. On a 4-Way trailer end, the one covered pin is the ground. Next to that is the running light pin. The running light pin on some connectors will have more than 1 wire coming out. One of those wires is for the driver's side running lights and the other is for the passenger's side running lights. So it could be a situation like that. On the actual trailer lights look at where the wires go into the...

  • Troubleshooting Trailer Lights After Installing Hopkins Replacement 4-Way Connector # HM48192
    The part you referenced, Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector # HM48192, has LEDs to indicate the presence of a signal. Since your connector's LEDs are lighting up this tells us that the signals from your tow vehicle 4-way connector are reaching the Hopkins connector. Since none of your trailer lights are working, the most likely explanation is a bad ground. Check the trailer's ground wire that connects to the trailer frame. This will typically be a white...

  • Replacement Wishbone Connector for Damaged 4-Way on Trailer
    What you have that got damaged is a wishbone harness, and the Hopkins Endurance Quick-Fix 4-Way Connector # HM48192 will work, but you would need to combine the two running light wires and turn it into one wire. Or you could simply get a new wishbone 4-way # A20WB, cut off the connector and use butt connectors # DW05743-5 to combine the wiring. I've added links to video reviews of these parts for you to take a look at.

    On many German vehicles such as your 2011 Mercedes GL550 there is a bulb out sensor error that occurs when a trailer with LED lights is connected to the vehicle. This is because the LED lights draw such a small amount of power the vehicle computer thinks there is a bulb out and won't light the trailer lights. There are adapters designed to correct this problem by using load resistors to draw more power so the system will function normally. You can use adapter # TR20141. It plugs into...

  • Trailer Side 4-Way Recommendation with Wishbone Wiring for the Running Light Circuit
    Sounds like you are looking for a wishbone trailer wiring harness. One that has two wires run to the (brown) running light circuit. I have a solution for you, but the # HM48192 would not be the correct part. You would want the part # A20WB instead as it has a wishbone setup already with two wires running out of the running light circuit pin.
