Video Transcript for Hopkins Wiring - Trailer Connectors - HM47210 Review

Today we'll be reviewing part number Hm47210. This is the Hopkins endurance quick qnstall 7-way trailer connector with a universal pigtail harness for the vehicle end. The 7-blade, RV-style trailer connector for your vehicle is a pretty simple install. The pigtail harness just simply hardwires into the truck's existing wiring, and the 7-way connector flows directly into our harness. You just push them together after you've got them lined up right, until you hear them click into place. You do want to be sure that you match up your wires to the correct wires on your vehicle.

The white is going to be our ground wire. Yellow is going to be our left turn. Green is going to be our right turn. Brown is going to be our tail light. Red is going to be the auxiliary power lead.

Blue is going to be our electric break, and purple is going to be the back up or reverse light. The lid does open 180 degrees for easy connections. It's also going to help keep out dirt and moisture. This does have enhanced weather proofing with the internal seals and currosion-resistant terminals. It comes from a durable, AVS plastic with an over-sized lid hinge. The mounting screws and the grease are included.

Our mounting screws are separated by an inch-and-a-half here on the side, and two-and-one-quarter inches here on the bottom. You're going to have a mounting of one-and-a-half-inch by two-and-a-quarter-inch. That's going to complete today's review of part number Hm47210, the Hopkins Endurance quick install 7-way trailer connector. .

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

Average Customer Rating:  4.9 out of 5 stars   (50 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.

by:

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.



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:

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:

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:

Exactly what I needed!



by:

the item came quickly after I placed the order, it was simple to install.
5 thumbs up !!!



by:

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!

product is working fine-easy installation
Jack G - 08/11/2018


by:

Received today



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 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:

good product but shipping is slow



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:

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:

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:

Excellent Will definitely order again excellent customer service



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:

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:

I have always been happy with the items from etrailer and intend to continue buying their products



by:

with wiring harness installation was easy ...worked well



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:

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:

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:

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:

i was thinking it would have the bracket included otherwise great products

Ask the Experts about this Hopkins Trailer Wiring



  • 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.

  • 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.

  • Replacement 7-Way and Wiring Harness for 2012 Ford F-250
    The Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness # HM47210 would work well for you if you somehow damaged the wiring harness of your 2012 Ford F-250 and need a new connector with wiring and a new 7-way.

  • 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.

  • 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.

  • Compatibility of Hopkins 7-Way # HM47210 With # 41157 Gooseneck/Fifth Wheel Wiring Harness
    It sure would. The Pigtail of the # HM47210 unplugs from the pigtail, and the # 41157 would plug inline between the pigtail and the 7-way connector as shown in the photo I've edited for you. If you click the provided link, you can see the # 41157 being installed on a 2011 Ram truck.

    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. In order to convert from a euro 7 to a US 7 way you will need to cut off your current one and hardwire a 7-way. You will also have to add wiring for the other functions. I recommend the Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM47210 for the 7-way. In order to install it you need to these the wires that you currently have and connect them to the...

    If you use the 7-way that is used for commercial/industrial/agricultural application like # PK11720 or the RV/standard 7-way like # HM47210 you will need to utilize the same location. The reverse signal should be connected to the center location of either application. You will simply need to make sure your wiring corresponds with the function locations. I've attached a photo to assist. For a 7-pin that normally does not have a reverse light, that means utilizing the auxiliary in the...

    The 7-Way on a semi-truck is not the same as an RV style 7-Way and there isn't an adapter.

  • Trailer Brakes Locking When Lights Turned On
    This isn't the first time I've heard of this type of issue. It sounds like the functions of your trailer wiring are not synced with your truck. Because you have used two trucks, the issue appears to be with the trailer. I've attached a picture to help, because I think your brakes on your trailer are being connected to the running light function on your truck. There also could be a short between these two circuits because they are side by side. If that is the case, replace the connectors...

  • Recommended 7-Way Trailer Connector For 2003 Volvo XC90
    We do not offer any adapters that convert a Euro 7-way plug like you have on your Volvo to an RV-style plug needed for your trailer. The only solution I can recommend is to cut the Euro 7-way off of your vehicle and wire a new 7-way to your vehicle by function. You would need to use a circuit tester like part # 40376 to determine the functions of the wires by having someone run through the functions in the car while you test the wires with the 3808 to determine what each wire function...

    If your 2008 Dodge Ram 1500 had a factory 7-way trailer connector before the Euro connector was installed then there should be a port under the bumper at the rear of the truck. It looks like the picture I've attached. If you have that port (and it works) you can just plug # 20135 for a 7-way and 4-way connector. If you don't have that port on your truck it's either been removed or the truck didn't come with the factory tow package. All of the functions should be there for the 13 pin...

Your best option may simply be to cut off the 5-Way flat connector on your truck and connect the wires to a 7-Way like the Hopkins Endurance # HM47210.
