I recently had a need for the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Vehicle End - HM48190 to replace the faulty one on my van. It was easy to find what I needed on the site and the price was comparable to other sites I had visited. I decided to go with etrailer because I had previously ordered the hitch through them. I appreciated the fact that an email was sent out confirming that they received the order as well as a follow-up email telling me that the part was shipped along with providing the tracking number. The installation of the part was easy and took no time to complete. Overall it was a fine experience and if I need to order anything in the future, I will be sure to come back and order from etrailer.

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.

The pigtails that I purchased are still in excellent condition and have held up well in the weather.



by:

Wanted a connector I could bolt to my bumper instead of leaving it dangling. This fit the bill. My only complaint is that the no-strip wire connectors were apparently designed for a heavier gauge wire than my wiring harness has (no gauge range stated on the web site or packaging), so they didn't make good contact on the first try. I had to double the wires over before pushing them in so they made good contact (that made them a little too tight but it worked). I didn't originally think I needed the LEDs, but they came in handy letting me know about the connection problem, and reassured me that my fix took care of it.

Some of the lights on my trailer have stopped working. I havent had time to investigate, but I would not be at all surprised if it is related to the wire gauge mismatch.



by:

Great product. Easy to install



by:

Very Good Customer Support.

Thank
You



by:

Hard to find but best method for a clean hookup.



by:

Good quality fast shipping



by:

My Toyota 4-Runner has the trailer wiring hookup on the left side of the truck instead of the center near the trailer hitch so I have to use an extension wire. I replaced the end that the trailer plugs into with a matching end of this product so that the length allows me to tywrap the new end by the trailer hitch area. I then replaced the trailer connector with the same style of this product. It’s now a breeze to test the trailer lights and determine if and malfunctions are on the truck or trailer wiring.



by:

This connector was just what I was looking for to avoid doing any soldering or the entire harness. Was quick and easy to install. As a bonus, delivery was expected on a Mon., got it on Fri. Thanks!

Worked good for a short time then I noticed one of the lights out on it. Tried getting better contact then it never worked again so I just took it off.



by:

I broke the ground post off the hitch connector on my 2008 Toyota RAV4 and I bought this replacement connector on your website. It was very easy to just clip the four wires on my broken connector and insert the wires into this replacement connector. The replacement connector has two screws to open it up and then you just push the four wires into each push "V" connector. No stripping wires or terminal screws. The LED lights work just like the description on the website which made it easy to confirm the connections were good. The overall project took about 30 minutes. The only problem I had was that
the two bracket holes didn't match the holes on my tow bar, so I could only use one screw to re-attach the new connector. I used electrical tape to secure the wires so they wouldn't hang down.



by:

My electrical connection to my trailor works very well with this connector.

I have used this product for a year now and it works as good as it did when I purchased it. Great product.



by:

Product is good, easy to install. Light on individual wire makes it easy along with the clear instructions that come with it. Video of item is very helpful.

Worst thing UPS to USPO mail service: always seems to be a day or two dead period.

Great, still working



by:

Could not have been simpler. Backed truck up on to ramps, unbolted the original harness (on which the ground plug had snapped off) verified the colors and placement of the wires on the new plug, cut them, slid the wires into this new plug per the directions, screwed the cap on and bolted it up in place where the original was. The LED's showed everything was working and it was done. No more than 10 minutes beginning to end. Could not have been easier or less expensive to repair my harness. A win/win.



by:

Trailer connector works great. Mounts easily and wires attach with a cover plate. LED's show everything is working. billooltewah



by:

great product fasten it under my trailer hitch with two self taping screws. took about five minutes.product was shipped and delivered on
time as promised. works great!



by:

This connector is much more robust than the standard ones. It was simple to install and the bolt-together cover keeps the wiring firmly connected. I have had no problems with either of my trailers. The end cap stays on and keeps the contacts clean. Finally, I like the red LEDs that tell you at a glance which wires are live. Trailer wiring the way it should be.



by:

Exactly what I wanted



by:

Great box for making all the connections for the plug harness, trailer brakes, and the brake battery and safety switch. etrailer has all the parts needed to rewire a trailer from plug to lights!!!



by:

Great replacement for my 2000 Ford Ranger and likely any vehicle with tow light connector.

My cables were a little thin for the internal V spikes that you splice the wire in to, so I needed to take a pair of needle nose pliers and wrap them around the lead inside.

Came with terminal grease, which I didn't expect.

The three lights on the connector are great to make sure it's all working.

Highly recommended.



by:

This worked like a charm and I'm about a 2/10 on the handyman skills level. Was easy to install and worked immediately. Service from etrailer was first rate - kept me up to date with shipping etc and followed up to check on my satisfaction. Delighted



by:

Best replacement connector! simple and easy to use and I love the test lights. solved my erratic non-working tail lights.



by:

I have not installed it yet but I like that it is sturdy construction with a hefty cap to keep the contacts clean. Extra added bonus is it actually has led's so that you know the connection is good! Only A few days delivery. Looks easy to install, no soldering or wire connectors needed.



by:

Ordered a bunch of stuff for hooking up a towed. Everything arrived as ordered and quick shipping. Everything fit the application without much trouble. Communication from etrailer was excellent. I would purchase from etrailer again.

great price - quick delivery - simple i nstallation

  • How Can I Determine If My 2023 Toyota Highlander LE Has The Factory Tow Package Or Not?
    The only way to really know if your 2023 Toyota Highlander LE has the factory tow package or not is to contact your local Toyota dealer with your VIN. They can tell you exactly what features your vehicle came with. Vehicles with the factory tow package would have the connector right behind the bumper like you described. So based on that, it sounds like you do have the tow package. We still recommend having a dealership run your VIN to be sure. If you do have the tow package, we suggest...

  • How To Make a Trailer Wiring Harness Adapter with Two Vehicle Side Trailer Connectors
    In order to obtain a trailer wiring harness with two vehicle side trailer connectors you will need to either splice two of the Hopkins Wiring Harness with 4-Pole Flat Trailer Connector part # HM48035 into one another with the Deka Heat Shrink Butt Connector part # DW05744-5 or you could just install the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector part # HM48190 onto the opposite end.

  • Using Hopkins Tow Bar Wiring on 2011 Jeep Wrangler That Needs Charge Wire From RV
    You can use the Hopkins tow bar light kit part # HM56200 on your 2011 Jeep Wrangler as it's a confirmed fit, but the 4-way ends of this and the # A10-6034VP don't match as they are both male 4-ways. So what you could do is cut off the 4-way of either side and install the # HM48190 in place of it and you'd be able to make the connectors as needed. For a coiled extension to adapt the 7-way or your RV to the 6-way of the adapter you'd then want the # RM-1676-7 which will carry the charge...

  • Converting Vehicle Side 7-Way Trailer Wiring to 4-Way Standard Wiring
    It sounds like you want to do a conversion from your 7-way to a standard 4-way trailer connection that has the 3 functions and ground. There are a couple different options for you that don't require much if you just need the 4-way connector for a trailer. You can use the Pollak 7 Pole to 4 Way Connector Adapter # PK12716 for the easiest connection. Your 2001 Xterra didn't come with a factory 7-way so you may find there is a 4-way plug connection behind your 7-way that you can simply...

  • Trailer Wiring Harness with 4-Way Flat Connector for 1997 Honda Valkyrie
    First, with LED lights, the color of the bulb needs to match the color of the lens. Otherwise you will have dim lights or off-color lights. If you want you can replace just the 4-Way end on the harness that you have with # HM48190. If you want to replace the whole harness I recommend going with a powered option such as # 119250KIT which will get the power for the trailer lights directly from the battery instead of drawing it through the tail light wiring.

  • Why Do Test LEDs Light Up Without Actual Trailer Lighting Signals Transmitted
    LED type lights are very highly efficient, using only about 1/10th the power required by standard incandescent light bulbs. This means that certain wiring harnesses will cause one or more of the LEDs to light up just from the very low-level residual power that "leaks" through a harness even when there are no full-scale signals being transmitted. This is entirely normal and does not indicate any malfunction in part # HM48190. If you have a voltmeter you can test each of the three circuit...

  • Adding a Removable 4 and 7-Way Trailer Connector on a 2005 jeep Wrangler Rubicon
    What you can do is replace the trailer wiring set up you have on your Jeep and hardwire in # HM40975-11998. This will allow you to just unplug the connector part. The wire functions and colors on this harness are a little different. Since the 7-Way part of the connector is hardwired on your Jeep, replacing the whole connector is the best way to go. On your current set up you should have a white, brown, yellow, and green on the 4-Way, and then a black, blue, purple, and white on the 7-Way...

    You do not need a mounting bracket with the Quick-Fix Connector # HM48190 as it comes with mounting holes that you can use. A mounting bracket would only cover the LED lights that allow you to confirm that the wiring circuits on your 2007 Ford Explorer are working properly. It is best to mount it somewhere that you can easily access and will be able to see the LED lights to check operation at the connector. The Hopkins Fold-Over Mounting Bracket # HM48595 will not fit over the Hopkins...

    To fix the 4 way connections you cut off, I recommend the Quick Fix 4 Pole Flat Car and Trailer Ends # 48195.

  • 4-Way Round Trailer Connection Much Smaller Than What I Can Find
    I have never seen a connection like that for a 4-way. Regardless of the pin size the slot is internal to the plug on the connection point instead of external as on current 4-Pole Round Connector # PK11404. I recommend replacing the connection with a standard size round connector # PK11404 or converting to the more common 4-flat # HM48190. The Adapter 4 Round to 4 Flat # will use the standard 4 round size connector.

  • Adapter to Go from 6-Way Square on Tow Vehicle to 4-Way Flat Trailer Side Connector
    It sound like you want the opposite of adapter # 30104. That would mean your tow vehicle has a 6-Way square connector. What you can do is use # 37995 which has both the vehicle end and trailer ends. On the trailer end, you can wire the loose wires to a vehicle side 4-Way, # HM48190. Then you will have a 6-Way square to 4-Way flat adapter. The other option is to just replace the 4-Way flat on the trailer with the trailer end 6-Way that comes with # 37995.

There are no premade adapters so this is the simplest solution. You could also cut off one of the male ends you and add the # HM48190 so you have less parts to purchase.
