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. .

This kit lets you add a 7-way, RV-style trailer connector to your vehicle with a factory tow package. Included harness plugs into existing wiring, and 7-way connector plugs into harness - no cutting or splicing required.


This worked as advertised, it was very simple to install, and it fixed it so my trailers lights all worked again! Very happy with it so far. :)


Great product that made for an easy ins tallation


A simple part… however, I have ordered hitches, wiring harnesses and other odds and ends. I buy from etrailer because they always have the right part, great installation instructions and videos. The quality is always spot on and the service is fast and helpful.
Why go elsewhere and hope things are right when buying from etrailer you know it’s going to be.

Chevrolet Silverado 2500

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!

2006 Dodge Ram Pickup

Took a little longer then I thought it would but got it in and I’m very happy

Still works great

Super customer service.


Everything went as planned with good co mmunication

2006 Dodge Ram Pickup

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.

Perfect! Could be more happier with this product

Nice looking product. Arrived 5 days ea rly!

2005 Land Rover Discovery II

I received the Quick-Install 7-Way Trailer Connector pretty quick. I had ordered one through another source, but had to return it because it was the wrong one. Then I searched on google and found After a little bit of searching on their site, I found this connector. They had great pictures and they were accurately-sized so I could see that the attachment holes to the frame of my 2005 Fleetwood Discovery RV would line up exactly. It matched up perfectly and installed in just a few minutes. The package was missing one nut, but that was no big deal as I quickly found a replacement.

Great. Better than the original.

2006 Dodge Sprinter

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.

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.

Was exactly what I needed

Working well after a year.

2001 Dodge Ram Pickup

Connector was as advertised it fit the existing wiring harness without any modifications made the replacement very easy I would reccomend this product to anyone.

It is working out great would purchase again
Pete M - 03/07/2018


Appears to be high quality components and materials. Included almost everything necessary, including grease to seal the connections. Liked the hex recess for the screw heads molded into the receptacle body. Would have been nice to include Nyloc nuts - Was concerned about tightening the screws enough to make the lock washers work while not damaging the plastic. Used Locktite instead.

Still working well :Thanks!
Mark W - 08/27/2014


Perfect fit! Thank you for your help!

2007 Dodge Ram Pickup

As advertized. Plugged right in. No splicing or taping required. Had to drill a cpl new mounting holes. Face plate was a little smaller but all the important stuff fit correctly.
Much better than searching thru auto parts stores.

After a year still working as it was from install. No problems with connectors or housing. Still 5 stars.
jeff M - 10/09/2017


I found it odd that local parts stores didn't carry this item, as it is a standard Dodge truck plug. So I hit the Internet and found it here at a good price. It was delivered much faster than I anticipated.

It works perfectly
Rich S - 04/22/2015

2013 Mercedes GL450

This product its awesome !!!

a silly mistake on my end I broke the OEM Connector on my 13' Mercedes GL450, called the dealer and was told the connector doesn't sell individual and I had to order the Towing Kit (Over $900 !!!) decided to take my chances on aftermarket products.

Began by ordering part# PK11893-11933 from only to discover that the mentioned part worked fine but it didn't fit properly on the OEM Bracket (You had to drill new holes) when taking the plug out to disconnect it I broke the pin so sadly I couldn't sent it back for a refund.

Still, I was determinate to find a perfect fit, so I ordered this part from and this time I got it right. The part fit perfectly and you can even use the stock screws, also the part its rugged and you can tell its a great quality product. Very happy with my purchase. Thanks

2001 Dodge Ram Pickup

My 2001 Dodge Ram had the wrong plug installed and the connecting plugs from the lights from the factory and the wrong plug didn't match. Went to, searched for my truck, and this plug came up. Ordered it. Received it. Installed it with no issues. The connecting plugs went together easily. Tested it with the trailer and all lights work!!! Thanks etrailer!

1999 Dodge Ram Pickup

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.

2007 Dodge Ram Pickup

so far everything has been great installed the plug took about 20 minutes. drove to the campground plugged trailer in and all the lights work and brake controller lit up which is what was wrong with my original plug brake controller wouldn't work and now it does with the new plug i got from e-trailer. thanks for a great product.

Jeep Wrangler

The wiring connector I ordered fit perfectly and matched the original part I managed to destroy on my Wrangler while out doing some heavy duty Jeeping. I appreciate the reasonable price, rapid shipping and excellent communication with your company. Many thanks!!

After a year the product I purchased is working fine. Now, if I can keep from tearing it off the back end of my Jeep, all will be well!
