Video Transcript for Review of Hopkins Trailer Wiring - 7-Way Trailer Connector with Universal Pigtail Harness - HM47210

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Hopkins Endurance Quick Install Seven Way Trailer Connector with universal pigtail harness. This is a seven blade RV style trailer connector that will mount onto your vehicle. It's gonna be very simple to get installed. Your pigtail harness here is going to hardwire into your truck's existing wiring and then the seven way connector is going to plug right into that harness. As you can see, I already have it here but I can pull those apart so you can see those two different components together.

Once you get that assembled there, then it'll be ready for you to plug in your trailers a seven way cable there. This is an extremely durable ABS plastic construction so it is gonna hold up really well for you. This oversized lid hinge allows our lid to open 180 degrees so it is going to be very easy to make our connections there. I'm not gonna have to worry about the lid being in the way and then when it's closed, it is going to help keep out dirt and moisture to protect those connections. This does have enhanced weatherproofing with internal seals and corrosion resistant terminal so it is going to hold up well even being out in the elements for long periods of time.

Now the mounting screws and bracket that you're gonna need to get this mounted are sold separately. You can find those here at etrailer.com. Very simple to use those, to get this mounted on your truck. So that completes our look for today. Again, I'm Michael with etrailer.com.

Thanks for watching..

Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End - HM47210

Average Customer Rating:  4.8 out of 5 stars   (71 Customer Reviews)

This kit lets you add a Quick-Install 7-way, RV-style trailer connector to your vehicle. Included pigtail harness hardwires into your truck's existing wiring, and the 7-way connector plugs into the harness. Hardware not included.

Overall, I was very impressed by this connector. I used it as an in-bed connector for my gooseneck trailers. The plug seems to be a quality product, engineered to stand up to some abuse. I like how the mounting bolt heads recess into the connector and also how the bottom of the connector is elongated to help support the weight of the plug and wiring. I think it has a great shot at lasting for a very long time. The hinge is predominately plastic that will not corrode and break like the many I've had in the past.

Purchased Rv trailer socket for "in bed" installation in my Ram truck. Installation went smoothly and etrailer videos were most helpful in visualizing the install. Product works as described and ordering and delivery were on schedule. Thanks for the great service!

As good as the day I installed it Great having the reverse lockout when vehicle is put in reverse to back a trailer



by:

works just as intended. Install was easy, I did not use the included bracket because it would hang below the bumper. I mounted it inside the well on the bumper where you would put a bumper hitch. It is used only about once a month. I did have to run a brake controller wire because my truck was not equipped with it. 13 f150 xl



by:

Although I have just installed this I believe it to be very good quality and it should last a long time based on my inspection of it. Be sure to order a mounting bracket if you don't already have one as this unit doesn't come with a bracket. Hopkins bracket part # is 48615.

I like the fact that the harness plugs into the connector instead of having to strip and connect every wire into the connector individually. That should help inhibit corrosion which is the #1 cause of trailer electrical issues and it makes things much easier if I have to replace the connector later.



by:

I had the loose wire pigtail already under my f250 sd. I clipped the factory sealant off the end of the wires on the truck, stripped em back and attached with heat seal butt connectors. You will need the blue and yellow connectors as the factory wires are different gauges.

Etrailer has excellent how-to videos and detailed information about all their products it seems. It made buying and installing the right parts a breeze. They do the homework for you, their prices are better than most other online retailers and they ship fast. They earned my repeat business.



by:

I have purchased from etrailer several times and the products have always been as described. They ship fast and the products are packaged well. I hit my wiring harness on a log and needed to replace it. etrailer was less money then the auto stores and I did not have to drive 28 miles into Durango and back. Gas prices make online purchases great.

Thank You for being in business.

by:

This connector is just want I was looking for. It gives me a way to power my trailer via an external battery. I have attached battery clips to the leads. The construction is solid, and the documentation for each lead is excellent. For my cargo trailer, I use the lead for the running lights. For my travel trailer, I use the lead called accessories, I think.



by:

Quick and easy to install. Just splice wires( I use the shrink type connectors). No messing around trying to get wires under screws. And if the plug connector ever gets broke, all you have to replace is the connector. The wires are in a waterproof housing that unplugs from connector.



by:

Excellent Will definitely order again excellent customer service



by:

Exactly what I needed for less than half the price a local dealer quoted for purchase ($44, not including installation! He also wouldn't sell me just the kit, for the kit with installation he wanted over $100!) Do it yourself and save a bundle - make a few simple wire connections and plug and go - etrailer.com makes it quick and easy! Shipping is prompt.



by:

Easy to install and works well.



by:

The Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End - HM47210 works well no problem with the installation. All fit the original bracket.



by:

The item with a good layout of color coding where to install was awesome. I installed and plug in to my boat trailer and tested ... everything works in correct light function.
I will do business again with your company. Keep it up.



by:

Great customer service!!! Thank you Terri N for all of your help. The item ordered worked perfect.



by:

This was just what I was looking for. I have a motorized trailer dolly that I wanted to add this item to in order to operate my electric boat winch rather than having to back the truck up to the trailer.



by:

Product is great and easy to install. I only wish it would have come with the crimp connectors and heat shrink however that was my fault for selecting the wrong product.



by:

Works for me exactly as I hoped. A way to wire up a spare battery to run the lighting on the cargo trailer so as to not drain the truck battery.



by:

Work great. Just wish truck driver would quit moving the wires so that the plug pulls out and breaks the plastic. Easy to replace once the back plug is wired.



by:

Well made product. Will need to purchase mounting hardware and splicing material. Wire colors matched standard chevrolet wire colors with the exception of the backup/reverse which is purple on the pigtail vice light green on my truck.



by:

saves time trying to work with those little screws and fit the wire into the little holes....



by:

Good solid plastic lid.
Very easy to
install.
Drilled 2 1/4 hole in bumper and used 1 1/4 self tapping screws to fasten it.



by:

with wiring harness installation was easy ...worked well

  • What are the Mounting Hole Dimensions for Hopkins Endurance Quick-Install 7-Way Trailer Connector
    I went out to the warehouse and pulled Hopkins 7-Way # HM47210 from the warehouse to measure it for you. From side to side the mounting holes are 2-1/4 inches apart on center. And from top to bottom they are 1-1/2 inches apart on center. I have included a picture and a video for you.

  • Replacing a 6-Way Trailer Connector in Truck Bed with a 7-Way
    You sure can. I recommend using a 7-way with wire leads like part # HM47210. This way the wire connections are easier to make. Your 6-way is probably lacking the reverse light circuit which may not even be needed on your trailer. On the # HM47210 connector that's the purple wire. It connects to your truck's reverse lights or if you don't need it you don't need to make that connection. The other wires will work function for function from your 6-way to the 7-way. Just make sure to...

  • Pigtail Length of Hopkins Endurance Quick-Install 7-Way Trailer Connector
    I journeyed out to the warehouse to measure the pigtail leads of the Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness # HM47210 for you and found that they were approximately 8-1/2 inches long, while the ground lead was approximately 15 inches long.

  • What is the Wire Gauge Of the Wires on the HM47210
    The maximum amperage on wires is going to depend on the gauge of the wire. The wires on the Hopkins Endurance # HM47210 are as follows: Red, Blue and White wires = 12 gauge (20 amps max) Green, Yellow, Brown and Purple = 16 gauge (10 amps max) I did call Hopkins to confirm these specs with their product manager.

  • Can Hopkins 7-Way part # HM47210 be Installed on Trailer and Connect to Trailer Battery
    Yes, what you described is very common and would work well. The part # HM47210 that you referenced can have it's 12 volt power circuit wire ran to a trailer battery that is powering an electric tongue jack. People do this all the time and it works very well. Or if you wanted to use a pin on this connector as a different way to connect wiring to a battery that's possible as well.

  • Troubleshooting Trailer Brakes that Lock Up When Blinker is Applied
    Sounds like you have a short between the brake output circuit on your trailer wiring and one of the stop/turn circuits which is causing the brakes to get the full 12 volts of braking power when the blinker is on. So what you'll want to do is go over the trailer wiring and vehicle's trailer wiring looking for any obvious signs of a short like exposed wire or corrosion and fix as needed between the two circuits. I also attached a help article on brake controller troubleshooting for you to...

  • Wire Gauge Used on the Hopkins 7-Way part # HM47210

  • Replacement 7-Way Recommendation for 2016 Ford F-150 with Curt Echo Brake Controller
    The solution is definitely to get a new 7-way which the part # HM47210 will work great for your 2016 Ford F-150. The round socket on the back of the connector will plug right into the matching connector that your truck has. The blade that has fallen out is the 12 volt accessory circuit pin and it is what the controller needs for power. Right now it's making an intermittent and unreliable connection which is why it's not always working. This can be really dangerous as it might not be on...

  • Compatibility of Hopkins 7-Way # HM47210 With # 41157 Gooseneck/Fifth Wheel Wiring Harness

  • 7-Way For Freightliner Semi
    I'm going to assume you don't have any trailer wiring as you didn't mention any, so what you can do is add the Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End # HM47210. On this 7-way, the white wire is ground, yellow is left turn signal and brake lights, green is right turn signal and brake lights, brown is the tail light wire, red is auxiliary power, blue is output to electric brakes, and purple is reverse lights.

    A Euro 7-way does not have the same functions as the traditional 7-way, it is basically the equivalent to a traditional 4-way.
