It's a great item to use when you're tailgating. This will plug into the 7-way RV connector on your vehicle, the right here if you pop open the cover you can see you can be able to plug in the 4-way flat. If you remove this little plug right here, it'll allow you to plug in a 5-way flat.

When you're not using it, just push the cover, it seals very nicely. Over here you just pop open and this will give you a 12-volt power socket which will come in handy at the rear of the vehicle because you plug in like an air compressor or anything else that runs off the 12-volt battery. Nice thing are these covers, they do help the terminals from the elements. That should do it for the review on part number HM47675. This is the Hopkins multi-tow trailer connector adapter. .

Excellent product and its even better that it has a 12V connection. No longer do I have to go into the car to plug in my tire inflator or any other accessories running off the 12 V connection especially if you tailgate this item is a gem. 84198

The HM47570 and the HM47675 Adapters are an absolute must to have when you tow multiple different types of trailers. Another advantage that I personally like is to use the HM47570 to keep from wearing out my 4&5 plug on my Ford truck. These Adapters are built tough to last. 305834

Ditto On The Original Comment. Mud, dusst, multiple vehicle washes and there still are no changes to the system. Still works like a champ.

Solid and very well constructed. When attempting to use it in my 2017 F-250, I did not have 12V in the unit. After much angst, I determine that Ford did not install a 30 Amp fuse in spot 27 in the electrical distribution box. That circuit supplies the 12V needed to charge a battery on your trailer while driving. Heading to the dealer tomorrow to have them answer some questions. Product is solid. Recommend getting one it you are in the market 561589


Comments
The 12-volt accessory circuit to the 7-way is frequently referred to as a charge circuit, but due to the small diameter of the wire feeding the 7-way and the distance from the alternator to the battery on the trailer, theres not going to be enough amperage through the circuit to charge a trailer battery. Itll maintain a charged battery, but wont charge one once its been discharged.

product works fine. However, the F-250 will not supply power to that receptacle until it detects a trailer attached to the truck.

- HM47675
by:

Easy to insert in female recepticle. Fits 12volt plug on my thermoelectric cooler which is main reason I purchased it. The weight of the large head does allow the large end to sag down slightly. Since I bought it to run my portable cooler in the bed of our pickup truck while we travel, I am hopefull that vibrations don't allow it to fall out. Even though it has a small tab to catch on recepticle cover, I'll probably secure it to the door of my female recepticle with tape or a bungie cord to avoid loosing it on the road. Plan on using it first time next week on trip to VA. 394612

This product works well for my application of needing to use a flat 5 connector. So far it has stayed in the 7 pin connector on a Tundra because the cover lowers onto the adapter's ridges on the top of the adapter. I only gave it 4 stars because the little plastic nub on the 4/5 connector door either arrived broken or broke after the first time I used it. To etrailer's credit they shipped out a new one very quickly. I have opened and closed that door 5 times without damage so I hope it continues without breaking. I have not tried the 12V power socket yet. 386044

  • Wiring Harness to Add 4-Way Flat Connector on 2017 Nissan Frontier
    You can add a 4-flat to your 2017 Nissan Frontier; since you do not have the factory 4-flat you would need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118525. This will plug into your Nissan Frontier's wiring harness, which is located beneath the rear of the vehicle, along the driver's-side frame rail. I've added links to a video review and install of this harness for you to take a look at.

  • Comparing Reese and Hopkins 7-Way to 5-Way Adapters
    I'd recommend the Reese # 78118 7-way to 5-way adapter over the Hopkins part # HM47675 that you also mentioned because the Reese comes with a circuit tester which for most people would be more useful than what the Hopkins has instead which is a 12 volt power circuit. There are quite a bit more situations where people are in need of a circuit tester than a 12 volt power supply so I believe it would be much more useful to you. I attached a review video for the Reese for you to check out...

  • Using a 7-Way to 5-Flat Trailer Adapter # HM47675 for Trailer with Electric Brakes
    The 5th wire on a 5-pole flat trailer connector like the Wesbar harness # W002290 can be used for either a reverse lockout function (as on a surge brake coupler) or to deliver a signal for electric brakes. It just depends on how your trailer is wired. 7- to 5-pole adapters like the Hopkins # HM47675 will typically take the 7-way's center pin function and assign that to the 5th pole on the 5-pole output. For an RV-style 7-way this center pin usually carries the reverse light signal, not...

  • Powering Trailer Mounted Winch from 7-Way Trailer Connector
    The wiring that feeds the 12-volt accessory circuit on the 7-way trailer connector is of insufficient gauge to allow enough power to pass through to run a trailer mounted winch. The main function of that circuit would be for lighter-duty applications, such as providing power for interior trailer lights or to maintain a trailer mounted battery. To provide power for your trailer mounted winch, you can either install a battery on the trailer to power it, or use a quick disconnect like...

  • Can Hopkins Multi-Tow Trailer Connector Adapter HM47675 Deliver Lights and 12V Power Simultaneously
    The 12V power circuit on a 7-way trailer connector is separate from the lighting circuits. If you use an adapter like the Hopkins Multi-Tow Trailer Connector Adapter # HM47675 the 4-and-5-pole connector will carry the stop/turn/tail light signals for the trailer lights while the 12V power outlet will deliver a maintenance-level charge to keep a charged battery topped off. Both will operate at the same time. Do note that this 12V power feed, which comes through your F-150's trailer wiring,...

  • Can a Trailer Connector be Used to Power an Electric Trailer Winch
    Electric winches should have a direct connection to a battery for power. The wiring in a trailer connector, like a 7-Way, and an adapter like # HM47675, is not a heavy enough gauge to effectively power a winch. Also, the farther away from the power source the winch is, the heavier the wiring will need to be. I recommend using a wiring kit specifically for electric winches like Trailer and Vehicle Electric Winch Wiring Kit, for up to 16.5K Winches, # SW2008. I have included a link to...

  • Can the 12 Volt Outlet on Trailer Connector Adapter, # HM47675 Charge or Maintain a Trailer Battery
    The 12 volt outlet on the Hopkins Multi-Tow Trailer Connector Adapter, # HM47675, can be used to maintain a trailer battery but it will not be able to charge it. The gauge wire used to provide power to the 7-Way is too small to effectively charge a battery, but it will provide enough power to keep it from draining.

  • Which Post On My 7-Way is the 12 Volt Power Source
    The 12v lead should be connected to the first prong clockwise from the top of your 7-way plug, but you will need to double check your existing application to confirm that it is wired this way. The color of this wire is typically black. I would recommend you use a Quickee Circuit Tester, part # 3808, to determine if you have power at this post. If not you should check the wiring on the back of the 7-way connector and then follow it back looking for any cuts, or corrosion that might be...

  • Parts Needed to Install Always-On 12V Power Outlet in 2017 Honda Ridgeline
    The 12V auxiliary power feed included in a 7-way trailer socket will remain active on some vehicles even if the engine/key is off; on other vehicles it will be key-controlled. It depends on the type of installation. If you want to have a 12V circuit that stays on at all times to keep your fridge powered up you can certainly install a power receptacle and wire it directly to your battery (without using the 7-way). You'd just need a 40-amp breaker # PK54540 and wire # 10-2-1, along with...

  • Will the Hopkins 7-Way to 4- and 5-Way Trailer Connector Adapter Work on a 2006 GMC Envoy
    Provided that the 7-Way on your 2006 GMC Envoy is fully functional, then all of the pins on the Hopkins adapter, # HM47675, will work. On the harness, the pin for using this unit with a 5-Way flat requires that the reverse light circuit on the 7-Way is attached and functions. This is the center pin on a 7-Way. If it is not working on the Envoy, you will need to run a wire from the back center pin on the 7-Way to a reverse light and tap into the wire there. The 12 volt power socket...

If the 7-Way works on your truck then that would indicate that the fuses/relays are working fine on your truck. To locate them just to be sure you can use the owners manual and/or the legend on the power distribution box lid. They are normally labeled as trailer...

    The capacity you need to be aware of is the vehicles electrical capacity for the tow package wiring. Most factory tow packages will use a 30 to 40 amp fuse or relay on the 12 volt circuit. Consult the vehicle owners manual for the fuses/relays related to the tow package wiring and do not exceed them when using Multi-Tow Connector # HM47675 or really at any time.
