Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM42190 Review

Today we're going to review part number HM42190. This is the Hopkins Endurance quick install 7-way trailer connector. This kit will allow you to add a 7-way RV style trailer connector to your vehicle that has a factory tow package. This part number is a custom fit part number. It is designed to fit the Dodge, Chrysler, Jeep and some Mercedes Benz vehicles starting in 2000 that have the factory to 7-way connector. What I would recommend is go to our website and on our fit guide you can put in your year and model vehicle and it will show you the exact years and models that this will fit on. This is a 7-way blade RV style trailer connector for your vehicle with the factory tow package.

It is a plug-in simple installation, there is no cutting or splicing of wires. The wiring harness plugs in to your factory wire port at the rear of the vehicle and then the 7-way will plug right in to here. Oops, turn it around, just like that. That will be plugged in to your factory wiring harness. The lid on this will open 180 degrees you can see for easy connection.

This lid also helps keep out any dirt and moisture from getting to the terminals. It has enhanced weather proofing with internal seals right up in here and corrosion resistant terminals. Extremely durable ABS plastic construction, it has a nice oversize lid hinge. It comes with the mounting screws to mount this to a bracket and a package of dialectic grease which we recommend to put on the terminals when you do your connections, also on this right here. That should do it for the review of part number HM42190, the Hopkins Endurance quick install 7-way trailer connector. .

I received a Hopkins 50002 Smart Hitch Backup Camera System for Fathers Day but my 2006 dodge diesel had the old square style 7-way connector. I did not want to splice into my wires unless I had no choice. I had recently bought some awesome new tail lights for my boat trailer from etrailer and I thought maybe I could find something there that would make this hook up possible without splicing into my wires. I'm certainly glad I did because they had the new style 7-way connector, just what I needed. I ordered it, installed it along with the camera system and life was great. No splicing wires! Thank you etrailer for making this Fathers Day gift a breeze to install. 529510

I received the product sooner than I anticipated and was happily surprised. It is a good quality product and if it was actually the part I needed it would be overjoyed. The fault is not on any one but me for not knowing exactly what I needed. I would highly recommend that people order for this company. 293140

Quality of construction appears good. There were no fasteners in the package. Main concern is that the pigtail adapter, necessary to adapt the OEM-specific harness to the "generic" outlet, was a little bigger/longer than I'd like. However, this is easy to live with considering the OEM part cost 3X as much! Haven't had the time to see if the wiring pattern for the trailer lighting is correct. 328073


Comments

It works fine but you have to watch out that you dont snag the pigtail adapter wire as you put the hitch into the receiver or hook up the safety chains.

I purchased this as a replacement for the damaged one on my 1999 Dodge Ram 1500. While this connector costs more than a generic one, being plug and play more than makes up for the added cost by eliminating the need to splice into factory wiring. The connector plugged directly into the factory harness and was a perfect fit in the original location. 77457

I purchased this to restore the 7-way recreational trailer connector on my Dodge 2500. The previous owner had cut off the factory connector box and connector. This connector plugged in directly to the truck's tow-package electrical cable connection, providing a quick and simple fix. Works great! 271813

The seven pole trailer connector is junk and sloppy first day I used it my boat plug fell out and drug the trailer plug down the road. So I put a new end on the boat and again it came on hooked! So I went to the locate farm store and bought a cheap 8 dollar one and problem solved!!! I called there Tec and no help so I won't be buying anything else from u again!! 530073

It is not a plug and play type connector. There is extra wiring and this does not fit my Jeep Wrangler. 500745


Comments

This particular trailer connector is a fit for Jeep Wrangler Unlimited models equipped with the factory tow package only. If it doesnt have the tow package, youd need to use part # 118416
T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
$19.10
and then an adapter like # 37185
Adapter 4-Pole to 7-Pole and 4-Pole
$22.95
to convert it to a 7-way. If the trailer has brakes, youll want to install a brake controller using the # ETBC7

$51.48

Do not recommend. When a customer relies on a online company to guide them to The right part The right part shouldn't state"not specific to your vehicle " which was the case with my purchase leading me to the part that was actually for another make of vehicle. Paid for 2nd day air which was the cost of the part and and didn't receive till 4 days later. Have nothing positive to add about my purchasing experience with this company and will not be a return customer. 481803

Mike, Thank you for your review. After looking at your account I see that you have a 2004 Ford F-250 or F-350. This Hopkins connector part HM42190 is not a fit. I would recommend Reese replacement 7-way part # 74682

This will make for a completely plug and play installation. In order to mount the trailer connector onto the vehicle I also recommend the Mounting Bracket for 7-Way part # 18138. For...

The easiest to install brake controller that also works really well is the Curt Echo Mobile part # C51180. Basically this just plugs into an active 7-way and once you sync it to your phone it's ready to go. This brake controller is proportional which means it senses the amount...

The ETBC7 install kit includes the 7-way socket, wiring, circuit breakers, connectors and everything you'll need to complete the brake controller install.

  • How Do You Determine If a 2006 Jeep Liberty Has the Tow Package Wiring?
  • With your 2006 Jeep Liberty, the factory tow package wiring is not easy to distinguish. If you have a factory 7-way that makes it easy as you know that the tow package wiring is there. The main difference between the tow package and no tow package is the wiring for the tow package gives you the rectangular connector under the vehicle that the 7-way # HM42190 plugs into. You can also use the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118381 which plugs into the...

For a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506.

Another option you could have is a 4-way which would look like part # 18172, or you might not have any connector at all. To add a 4-way you would first want the Tow Ready Wiring harness part # 118394.

But we also have # 20135 which is both a 4- and 7-Way and has that squarish connector. If you are not the original owner of the truck then it is possible that it came with a 4-Way flat (or someone added one) and then used a 4- to 7-Way adapter such as # 37185.

  • Troubleshooting Non-Functional Running Lights on Toad When Using Hopkins Dingy Wiring
  • When trailer or toad wiring has an issue with running/tail lights but other functions work fine the problem is most often related to a weak ground. What happens is that if a ground connection is not 100-percent solid and with bare-metal-to-bare-metal contact the weak ground will allow some lower-power signals to pass (stop and turn lights that don't draw as much current) but won't let the higher-current always-on taillights function. This is a common issue and it usually has a simple fix. Find...

  • Installing 7-Way Trailer Connector in Bed of 2006 Dodge Ram
  • Hopkins offers a T-Connector type set up, part # HM42137 that would plug inline with the existing 7-way on your bumper and provide a 7-way in your truck bed. The wiring harness is 8 feet long, but any existing slack can be taken up and bundled up under the vehicle with zip ties. Using the T-Type connector will allow a 7-way to remain at the rear bumper while adding one to the truck bed, which you would not have if you simply relocated the existing 7-way to the truck bed. The HM42190...

  • Recommended Wiring Connector for 5-Way Boat Trailer Connection with 2009 Jeep Wrangler Unlimited
  • We do not carry a 5-pole wiring harness that is vehicle specific. For your 2009 Jeep Wrangler Unlimited, you can install the 4-way # HM42635 and then splice in the vehicle side 5-way flat # HM47900 using butt connectors like # DW05744-5 to give you the 5 way. This will give you the connection without the adapter # 47515 needed each time as a 5-way will still work with a 4-way connection without issue and be a better connection for your boat trailer's 5-way. Your other option is to...

  • How to Install Hopkins Smart Hitch Backup Camera # HM50002 on a Dodge Ram with Square Connector

  • Adding a 7-Way Trailer Connector to a 2001 Jeep Grand Cherokee
  • 7-Way trailer connector # HM42190 for a 2001 Jeep Grand Cherokee looks similar to a 4-Way but the end that plugs into the vehicle has 7 pins in it for the 7 functions on the connector. It is not a confirmed fit though unless the vehicle originally had a 7-Way connector from the factory. Even if the wiring is there it doesn't necessarily mean that it is active and functional. The accepted method for adding a 7-Way to a 2001 Jeep Grand Cherokee that didn't come with one is to first install...

  • Parts Needed to Install Brake Controller in 2015 Jeep Wrangler Unlimited
  • You would not need to have the computer of your 2015 Jeep Wrangler Unlimited flashed once the brake controller install components are installed. The first thing you will want is a 7-way trailer connector at the rear of the vehicle and for this I recommend the Hopkins Endurance Quick-Install 7-Way Trailer Connector part # HM42190 which is a direct plug and play option that will not require you to cut or splice any wires/circuits. The square plug on the end of this connector will plug...

  • Is There an Adaper to Install an Electric Brake Controller on a 2007 Mercedes-Benz GL450
  • If your 2007 Mercedes-Benz GL450 has a brake controller connector under the dash you likely need to get the adapter from Mercedes; unfortunately that's not a part we carry. Then you need to install the Prodigy P2, part # 90885, by wiring it to the adapter you plugged in. On brake controllers the wiring is color specific: Blue - Brake ouput Black - 12 volt power White - Ground Red - Stop light switch You can test that green connector using a circuit tester, like part # 40376,...

  • Trailer Wiring Harness Recommendation for a 2003 Jeep Grand Cherokee
  • If you have the tow package on your 2003 Jeep Cherokee there should be a factory wire under the rear of the vehicle that would allow a Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM42190 to install. This product comes with installation instructions, but its a pretty straight-forward install that basically just requires mounting the connector and then simply plugging it in.

  • 7-Way Trailer Connector for 2008 Jeep Grand Cherokee with Factory Tow Package
  • I have a solution for you, but the Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket # PK11893-11933 is not confirmed as a fit for your 2008 Jeep Grand Cherokee. For a similar 7-way connector that is confirmed to fit the 2008 Grand Cherokee with the factory tow package you can use the Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM42190. For a 7-Way and 4-Pole connector that will fit the 2008 Grand Cherokee with factory tow package, the Tow Ready Multi-Plug T-One...

  • How to Determine if 2013 Jeep Wrangler has Factory Tow Package and Adding 7-Way and Brake Controller
  • The easiest way to determine if your 2013 Jeep Wrangler has the factory tow package is to have a dealer run the VIN. They should be able to tell you how the Jeep was equipped using the VIN. But if the Jeep came with a 4-Way and not a 7-Way then it is probably not the factory tow package which I do believe came with a 7-Way connector. To add a 7-Way to models that did not come with a factory 7-Way you would use # ETBC7. Your 4-Way will plug into this adapter and provide both a 4- and...

  • How to Activate 7-Way Auxiliary Power Circuit on 2004 Jeep Wrangler
  • When checking fuses, did you check the fuse box under the hood, as well? There are fuses in the power distribution box, the lid of the box provides a diagram showing which fuse protects which circuit. I'd look for a circuit marked Trailer Charge or Trailer Auxiliary Power, and replace the fuse if it's missing or blown. Due to the distance between the alternator on the Wrangler and the trailer battery, the size of the alternator and the small wire gauge, the auxiliary circuit from the...

  • Recommended 7-Way Trailer Wiring Harness For 2013 Jeep Wrangler Unlimited Rubicon
  • The Hopkins Endurance Quick-Install 7-Way Trailer Connector, part # HM42190 is compatible with your Rubicon if it has a factory tow package and a 7-way trailer connector at the rear of the vehicle. Since you said you have a 4-way connector at the back of your Jeep, it sounds like you want to add a 7-way connector. If you do not plan on adding a brake controller, you can use part # 37185.
