looks good

fast easy install with provided instructions



by:

Exactly what i wanted and for less than half the price of my local store



by:

Better than I expected. Very high quality compared to items in local stores and shops. Great service and unbelievable delivery time



by:

Vast improvement over the old basic truck side connector this product replaced. Much more heavy duty spring closure and very easy wiring instructions.



by:

Gasketed cover. Comes with the mounting bracket. Nice latching cover at the rear to cover all wire terminations. Also includes plenty of dielectric grease. Terrific experience dealing with etrailers!



by:

Better quality and easier installation than some of the other trailer connectors that I have installed.



by:

I installed this receptacle in the side, top rail of my truck to supply power to my 5th wheel trailer. The connectors at the rear are very sturdy, I was able to tighten the connections very tight without fear of them stripping out. Looks like a factory installation!



by:

I do not recommend this product.
I bought
this for my truck. It seems to be the nicest looking plug on the market but after the first rain, the plug was filled with water. I changed the location from the hitch to the bumper and once again the plug was filled with water after it rained. This condition will obviously lead to terminals corroding and/or wires being shorted out. I have bought a different style plug, unfortunately the same brand but hopefully I will have better luck. May be able to drill a small drain hole in the casing to allow water to escape but shouldn't have to do this on a new product.



by:

I bought this socket for my 2006 Volvo Xc90 to wire in the 4-Pole harness I also purchased from etrailer. Already had a few 7 Blade to 4-Pole adapters from my previous vehicle, and wanted the option of adding a trailer brake wire for a small camper later on so that was the main reason for the purchase. It also went very well with the Hidden Hitch I had already installed, bracket mounted right up to the existing tabs on the hitch. Super quick and easy install, as all of my etrailer purchases have been. Looks great on the truck, and functions great with the 180 Degree cover.



by:

Well made. Correctly designed.



by:

Good quality with seal on cover. Wiring installation was a little tight with the housing. It did mount perfectly with my Draw-tite hitch.



by:

Very good service as always

I purchased this 7 blade connector to replace part 47435 (6 pole round to 7 blade (trailer)), which was allowing the whole cable assembly to droop close to the ground, and was fatiguing after four years of use. This new unit was easy to wire and install, however I wish to point out that the molded markings for the various wires (RT, LT, TM, GD, BR, etc.) are exactly backwards from the way the device is supposed to be wired. This was evident when I finished the installation and observed the turn signals were reversed, and nothing else worked (as a result of blown fuses). Once I corrected the wiring, everything works fine. Use the wiring diagram which comes with the instructions and not the molded pin markings on the device.

Thanks for the follow up. Thats impressive :- The two products are holding up fine. With respect to the Hopkins Endurance 7-Way Trailer Connector Socket - Vehicle End - Ergonomic Design, its working just fine, although the bracket is a little bent from being dragged on the ground when the back bumper on my KIA gets a little too close. Ive had to reinforce the mounting, because the fiberglass bumper isnt strong enough to take the hits. My problem, not yours. I will note, however, that the blades in the connector dont grip the slots in the trailer portion very well, so if I dont have the trailer part totally ed where the little latch in the top of the gate holds, the connecter easily falls out. As for the six pin to seven blade adaptor, everything is fine.

works great

STILL WORKING GREAT!



by:

Well I wasn't able to use this as there was no good place to install on my car without it practically dragging. Not a product problem at all. I tried to return and customer service was fast and super helpful... unfortunately return shipping would eat up any refund. So.. I get to keep it. good quality and product. Very happy with it and wish I could use it. Will keep it for sometime in the future when of course I will need it.



by:

Did not use this product…Installer of my Blue Ox tow package used another 7 pin connector..



by:

I purchased this draw-tite trailer hitch from etrailer about one year ago. I installed it myself, which was very easy to do without issue. Four bolt installation. Pre-drilled holes into the frame from the factory.I also purchased all of the wiring associated with the Hitch that was a plug and play into the right and left tail lights of the Jeep. There was no cutting no soldering no taping of wires. It was a matter of removing the tail lights a total of 4 screws, removing the tail lights, unplug the tail light wire and plugging in the wire kit and then plugging the wires back into the tail lights. I have to say this whole process took me about one hour total. Including putting the trailer hitch on and do the wiring. Everything has and continues to work well after a year and looks factory. Thank you etrailer.



by:

The receptacle has reasonable good terminals for hooking up wires. Since I installed it in Aug of 2018 and it is now May 2019, it is difficult to clearly remember, but I seem to recall it came with a diagram for wire connections. As with all the receptacles for plugging in the trailer cord there are two things that will fail before the receptacle itself; 1) the bracket will likely rust away, 2) the spring to keep the cover closed will rust away and fail to function after awhile. I coated the bracket with liquid rubber that is commonly used for tool handles, and tried to get oil in to the spring hinge. Also seal the area where the wire cable enters. Sparingly used wire conductive lube on the wire & terminals. I live in upstate New York where there is a lot of salt used on the roads in the winter. Hope to get 3 to 5 years out it. It's a good devise.



by:

Very easy to install. Good quality, looks like it will hold up over time. I ran my 4 pin right next to it for a clean look.
And as always great customer service.



by:

etrailer gave excellent service. Shipping was prompt. Email followup was excellent.

I needed a part to hook up to a Silverado 3500 with the wires to the bed already there (taped up at the front of the bed on the driver side) and didn't want to tap into the existing plug on the bumper.

The L Shaped bracket is easily detachable so that the plug can be screwed directly into the sheet metal of the truck bed once a hole is cut.

However 2 things....the unit comes with nuts and bolts so get ready for a trip to Home Depot to get some sheet metal screws of some sort for most installs in the bed. Second, the holes that the screws must go in are hex shaped which is great for the bolts that come with the unit but not for sheet metal screws so be sure and get screws with a small enough head to countersink into the holes or with a big enough base so as not to sink into the hex shaped holes.



by:

great service



by:

This is just what you need to fix a completely trashed factory receptacle, in our case, on a Toyota Tacoma. I had to flatten the mounting bracket because I couldn't remove the stock bracket (rusted bolt), but that was easy as long as you have a drill to open up the holes for the receptacle to attach to the bracket.



by:

Great product, shipped promptly. The video on etrailer.com made installation a breeze. Even comes with non-corroding grease for terminal connections.
I got stuck as an amateur wire-installer and had to call etrailer.com for some technical advice (didnt have a purple wire or orange wire as all wiring diagrams online showed....) the tech support was super knowledgeable and got me running in no time!

  • Troubleshooting Unconnected 7 Wire Harness Strand and Brake Controller
    Unfortunately your photo did not come through. I'm a little confused by the description...do you have a working 7 way trailer connector at the bumper and additional wires? If so, this may have been the wiring for a second 7-way for the bed of the truck like # 50-97-410. That would not be an issue with your brake controller not working unless the disconnected harness was defective and shorted your system. I recommend you use a circuit tester like # PTW2993 instead of a multimeter to...

  • Troubleshooting Brake Controller in Wet Conditions
    I can help you troubleshoot your brake controller issue. Sounds like water is getting into the 7-way connector between your connection. You will want to find a way to seal that off better, I have heard of people using electrical tape to wrap the connection to prevent water from getting in during wet weather. You may also consider replacing the connector with one like the Hopkins # HM48480, this connector has a foam seal that will help with weather seeping in. Another thing that may...

You have a ton of corrosion in there which can cause all sorts of problems from shorting circuits out like you mentioned (the smoking circuits) as well as causing intermittent connections like what your wife noticed when following you. You need to thoroughly clean the connector to rid it of all of the corrosion that you have or replace the connector with a new 7-way like # HM48480 which will give you the easiest...

  • Troubleshooting Electric Trailer Brakes Not Registering With the Brake Controller
    I can help you troubleshoot your brake controller error. Sounds like a grounding issue to the brake magnet ground. I would make sure that the ground wire is secured tightly to a clean surface on the frame. If the wire is attached to the body or a surface with an undercoating or rust it can cause a ground problem. I recommend cleaning the area or finding a better grounding spot for the wire. Another option would be to run all the grounds to the front of the trailer where the main ground...

  • Recommendation to Extend Factory 7-Way to Fit with New Bumper on 2010 Ram 2500
    There are a couple of options to extend the factory wiring at the rear of your 2010 Ram 2500 so that it can reach the new connecter opening on the 2015 bumper. The easiest solution is to use a 5th Wheel Wiring Harness like the Curt # C56070. This will plug in-line with your existing factory wiring and provide an extended harness on the other end. The only drawback on this option is that the Curt # C56070 represents the shortest 5th Wheel Harness that we offer at 7 feet long. So you will...

It can receive its 12V operating power either from your tow vehicle's 7-way socket which uses 12V power from the vehicle battery, or it can be powered from a secondary 7-way socket you could install on your trailer, along with a trailer-mounted battery. You could use 7-way part # HM48480, which includes a mounting bracket...

  • Can 10 Gauge Wire be Used with Hopkins 7-Way Trailer Wiring Connectors
    Yes, you can use 10 gauge wire like the part # 10-1-1 (sold by the foot) to wire up the 7-way part # HM48480 or # HM48500. Typically people use 10 gauge wire for the 12 volt accessory, brake output, and ground circuit and then use 12 for the remaining circuits.

    It sounds like you've created your own umbilical to go from the 7-way on your RV to a 7-way on your Jeep. The Hopkins connector # H20043 is 4 feet long, which isn't going to be long enough to bridge the gap of space for flat towing. You're going to need at least 6 foot umbilical.

    Since the 7-way of your 2005 International 4300 has the brake lights and the turn signals on separate circuits and standard 7-way RV trailer wiring has those two circuits combined what you'd need is the part # HM48847 to make the circuit conversion needed to then wire up the new 7-way like with # HM48480 and you'd be set.

    If the factory 7-Way connector itself is not present at the back of your 2000 Dodge Ram 3500 then there are a couple of ways you could add one. First, follow the wires at the back forward under the vehicle. They should plug into another connector that is rectangular. If they do then you could use # HM42190 to just plug into that rectangular connector. Or you could verify the functions of the wires using a circuit tester such as #PTW2993 and then attach them by function to a vehicle side...

    Technically, you could install any type of connector you wanted to at the front of your 1982 Chevy S-10. The problem would then be you would need a bunch of different extensions, like # HM47055 as an example, to go from the rental truck to the S-10. You would first need to wire the vehicle for lights. You can do this with diodes which would be a good idea since it is a more permanent solution and it sounds like you will be towing the truck often. You can use the Roadmaster Universal Hy-Power...

If you want the same gauge wire on the vehicle side, I recommend the Hopkins Endurance 7-Way Trailer Connector Socket - Vehicle End - Ergonomic Design # HM48480. These connectors don't specify wire gauge but will work with 8-gauge wires on the 12v and Ground pins without issue.

But it should not be showing 12 volts all of the time. If it is on the brake pin, 5 oclock position if looking at the face of the 7-Way, then that indicates that there is a short to the brake wire.
