Video Transcript for Hopkins Endurance 7 Way Trailer Connector Socket Review
Today in our motor home we're going to be taking a look at and changing the connector. We're going to be using the Hopkins endurance connector, part number HM48480. As you can see its got a rather substantial pivot point at the top. It's going to make it real strong and it's going to last a long time. We're going to start with our power wire and we're going to touch that to the auxiliary side of the wiring. It's going to loosen up, then we take our wire and slip it in between, then we'll tighten it back down. You want to pay attention not to have any stray wires sticking out that can come in contact with another connector. Now we'll do our tail lights, the brown wire, twist it, slip it into place. You want to be sure to test all your wiring to make sure they are the same colors as we're using here because some vehicles are wired differently. So it's best to take your test light and just test all the wires. Do our left turn, then we'll do our ground, then we'll do our right turn. Now there is a provision for a trailer brake which our vehicle does not have so once you have those attached. We're going to take some of the supplied Dielectric Grease and we're going to apply some to the inside here.
Just to cut down on corrosion. Then we'll take our cover, you want to place the screw side down, snap it into place and you'll hear it lock. We'll take our wires, push them back up there and we'll tighten up our set screw, it's going to hold the wiring in place. You just need a little bit of tension on it, you don't have to get to crazy and tighten it up. I'm going to take a little bit of electrical tape and go around the outside to keep it all sealed up. Now you take some of your Dielectric also and put it on the inside of your connections to help any kind of corrosion on the inside. Now we have the wiring done we're going to mount the supplied bracket. It does come with two supply holes in the bracket.
We've decided to mount ours to an existing bracket so we simply drilled another hole and we're going to use the two, the one we drilled and one of the original ones and attach it to that. There is a split in the middle of the bracket here so you close it little bit and you can stick your wiring right through it. Then we'll put our supplied bolts, as you can see the bolt fits into that piling, and we're going to put a flat washer or a lock washer and a nut, and we'll install them in all four of the holes. Now we can take our wrench and tighten them up. Then we'll tie up our loose wires and we'll test our plug. These are our tail lights, left turn, right turn and our brake signal. They are solid on both sides. There we go, and it all works. We're ready to plug in our trailer and hit the road. That's going to do it for our hook up and install of the Hopkins Endurance professional grade trailer connector.

This heavy-duty trailer connector socket has an outlet for a 7-way plug. A weatherproof, insulated lid covers the terminals. The cover is also easy to open and extra-durable.by: Mike B09/14/2017
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.

Worked great. Needed a 7 pin round trailer connector for my 1936 Chevrolet pickup. This will work on most any vehicle.

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.

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: Vic01/16/2013
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: William 09/04/2022
It worked well until I wiped it out when I hit a dip in a gas station driveway. :(

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.
Kent D - 01/06/2018by: Josh W04/22/2017
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: Charlie M.05/15/2014

Great info easy install
by: BigBuyerBill05/15/2019
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: Brian M10/08/2013
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: Peter V04/20/2015
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!
by: Brandon03/10/2013
Came with nice set of installation instructions and wiring diagrams. Also came with installation bracket and bolts for mounting, dielectric grease packets, and rear cover to help seal up connections. Well made product.
by: Robert12/29/2017
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: Mike S.07/15/2013
Great value. Toyota wanted $235 for the replacement which included an 18" wiring harness with a Weatherpack connector. I cut the Toyota harness at the failed socket and attached the wires to the new socket as shown in diagram.
by: Ray06/16/2020
Products were delivered with very short wait time.
Adapter cable HM47065 is a replacement of the original cable purchased for towing in 2012.
Socket HM48480 is a replacement of the socket that was on the motor home when purchased used in 2012.
They haven't been installed yet, but I don't expect any issues.
Thanks

Well made, durable. First one lasted 11 yrs until I broke the door - unrelated to travailing.
Easy to wire, and reassemble.
by: Kevin 08/28/2021
This is a good, sturdy, and well made RV connector.
by: Tim P.04/08/2011
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: PC09/16/2016
My factory connector cracked.
I installed a Hopkins plug on our trailer several months before, so I purchased the connector. It is a great product and easy to install.
by: Jason01/30/2013
Controller is very nice and installed easily. All mounting hardware was as stated and went in with no hitches. Very informed salesman and great to deal with. I would recommend them or do business with them in the future. Also shipping was very quick.
by: Paul R10/03/2016
Product delivered very quickly even here in Alaska. Had the same item installed on my truck and it had a broken cover plate so needed to replace it. Also found the original was not installed very well and let water into area where wires were terminated. Fixed that problem with the better weather sealing. Thanks for great service and a good product.
by: Greg H.10/15/2017
I have not put the product to use yet, but the quality exceeds what I had ordered and returned from another source. The shipment time was even better than stated when ordering.

I finally took the time to replace my old wiring harness with this product. I found it relatively easy to install. The directions were easy to follow. I tested the wiring after completion and everything worked. I have not driven the motorhome with towed vehicle attached.

- Troubleshooting Brake Controller in Wet ConditionsI 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...
view full answer... - Electric Brake Terminal on 7-Way Connector is Showing Constant 12 Volts Under All ConditionsOn some vehicles, the key has to be on for voltage to go back to the trailer connector. On others, it does not. An electric brake controller will always send back some minimal voltage to the trailer connector. This is how it senses if there is a trailer connected. 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. If the 12 volt power is showing...

- How to Make Adapter to Go From Semi Truck Connector to 7-Way Blade ConnectorI wish we did, but we do not have anything for semi truck to RV flat style connector.

- 9-Pole Truck Connector to 7-Pin Trailer Connector SolutionIs there a reason your truck has a 9-pole? Do you need all 9 functions active? Your life would be much easier if you cut off the 9-way and installed a 7-way in place of it like part # HM48480. This is a much more common type of connector that will allow you to work with your current trailer as well as with future trailers. I attached a diagram for the 7-way for you to check out as well.

- Can Hopkins Endurance 7-way Connector Be Installed In A Hole In The Bumper Of 2001 Toyota 4Runner?You sure can! You will just need to drill a hole large enough for the Hopkins Endurance 7-way Connector # HM48480 to fit through, and then you would just need to drill 4 holes for the mounting hardware. The included mounting hardware may not be long enough, so if that is the case you will just need to source some from a local hardware store. I included a video of the # HM48480 for you to take a look at.

- Service Electric Brake System Light on a 2008 Chevy Silverado 2500 with Factory Brake ControllerIt sounds like you have an integrated brake controller on the 2008 Chevy Silverado 2500. The "service trailer brake system" displays when there is a short with the integrated brake controller. I recommend to take a look at your trailer connector to make sure the pins are clean of rust or corrosion. If the 7-way pins are bent and you're not getting a proper connection then you could have a short. I recommend to have the truck to the dealership to be serviced.

I've also attached a photo that shows the dimensions between the mounting holes that you would need to secure the plug to your bumper so you can make sure that you have spots to attach the plug to.

- Troubleshooting Brake Controller Install Where Output Circuit Pulses Circuit TesterThe brake output circuit of any brake controller will periodically pulse the output circuit to see if a trailer is connected. What you are seeing is most likely that function. What happens when you connect a trailer with brakes to the tow vehicle? It sounds like you may have a controller that is working properly as-is. I attached a help article on troubleshooting brake controller installs to this page as well.

view full answer... - Can 10 Gauge Wire be Used with Hopkins 7-Way Trailer Wiring ConnectorsYes, 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.

The adapter would plug directly into the existing 4-pole, with 4 wires remaining. The blue wire would connect to the brake output wire from a brake controller. The black wire would connect to the vehicle battery via a 40 amp breaker like part # 9510, and would be used to maintain a trailer mounted battery, if needed. The white wire...

If you would prefer to use an adapter, we offer the 6-Way to 7-Way Trailer Wiring Adapter, part # 47435.

The best solution for you is to change the connector on your 1995 Jeep Grand Cherokee to a 7-Way because it is likely that all the adapters will have the same problem.

- Installing Hopkins Endurance 7-Way Trailer Connector, # HM48480 on a 2000 Chevy AstroWiring color/function on vehicle wiring differs from manufacturer to manufacturer and even among model years of the same vehicle, so the best way to determine the functions of the vehicle wiring is to test it with a circuit tester like # PTW2993.

view full answer... - Is Replacement Trailer Side 7-Way Connector # H20046 Male or FemaleThe Hopkins 7-Way connector, part # H20046, is a male connector. The trailer side is the male end because it inserts into the vehicle side. This is somewhat misleading because usually a male connector has prongs and vehicle side trailer connectors have the prongs even though it is a female connector. I've never seen a vehicle with a male trailer connector. Likewise with a female on a trailer. Take a look at the pictures I've attached and see if they match the type of setup you have....

- Can International 4400 Tow Trailer with Electric Over Hydraulic BrakesBasically you would need to install a brake controller with electric over hydraulic compatibility and a 7-way wired properly and you would be able to accomplish what you are trying to do.
