The tow-harness and components appears quite well made. Fit was perfect, installation was easy, and tested and worked the first time. The instructions, however, may have been more specific to earlier Pilots, thus were not entireley clear and caused some delay in installation. 404382

Ask the Experts about this Hopkins Wiring

  • Coiled 7-Way to 4-Way Recommendation for Towed Vehicle
    Yes, we have the Wesbar # 787196 which is an 8 foot long 7-way to 5-way. I know you need a 4-way but this will work well as the fifth circuit would just not be used.

  • 7-Way to 4-Way Adapter Recommendation
    I have a better solution for you, but technically the part # HM47065 that you referenced would work go from a 7-way to a 4-way connector. What would be a better solution would be the part # PK12716. This will plug right into your 7-way and will allow you to connect your 4-way to it.

  • Are RV 7-Way to 4-Pole Wiring Adaptors Vehicle-Specific
    Trailer wiring adapters like Hopkins # HM47065, Pollak # PK12716 and Hopkins # HM47365 are not vehicle-specific products. They will work on any vehicle that has the appropriate connector. The coiled wire adapter # HM47065 that you referenced combines a trailer-side (male) 7-way RV-style plug (that mates with the 7-way socket on your Ram 3500) with a vehicle-side 4-pole flat type plug. This wiring adapter carries only lighting signals (stop, turn and tail) but not other functions like...

  • 7-Way to 4-Way Adapter for a 2016 Honda Pilot with Factory 7-Way Trailer Connector
    You could use 7- to 4-Way adapter # HM47065 if you need the extra 3 feet of length the coiled cable provides. If you do not need the extra length you could use adapter # PK12716 and the trailer's 4-Way would plug into the back of it (which would be plugged into the 7-Way). I have linked video reviews of both adapters for you.

  • Connecting 4-Way Flat on Jeep to 7-Way on Camper
    I do have a solution for you, however the Hopkins Heavy-Duty Trailer Coiled Wire Adapter # HM47065 won't work to connect the 4-Way flat on your Jeep to the 7-Way on your new camper. This is because the 4-Way on your Jeep will be the female end of the connector, which is identical to the 4-Way on this adapter. The male end will be on the trailer side. This just means the adapter won't physically plug into your setup because they are matching, instead of corresponding/compatible, plugs. To...

  • Is Hopkins # HM47065 7-Way to 4-Pole Adapter Compatible with 2015 Toyota Tacoma
    The Hopkins # HM47065 is not a vehicle specific item, it will work in the 7-way of any vehicle and allow a trailer or flat towed vehicle with a 4-pole flat connector to receive lighting signals from the tow vehicle. The # HM47065 would typically be used for flat towing a vehicle, while an adapter like part # PK12716 would usually be used for a trailer. If you'd care to see a product description video featuring the Hopkins Adapter, please click the provided link.

  • Adding a 4- and 7-Way Connector to a 2009 Pontiac Montana with 4-Way Trailer Connector
    To add a 7-Way trailer connector to your 2009 Pontiac Montana with a 4-Way you will need # 37185. Your 4-Way will plug into this adapter's mating 4-Way. You will need to ground the white wire to the van frame. This adapter has both a 4- and 7-Way connector so you will retain the use of the 4-Way. The remaining wires on the adapter are blue for electric brakes, purple for reverse lights, and black for 12 volt power. You already mentioned not using the trailer brakes so the blue wire...

  • Trailer Junction Box Installation on Trailer to Avoid Use of Wiring Adapters
    Sometimes trailer wiring adapters do cause odd behavior from vehicle lights, trailer lights or both. It is often better to do an actual re-wiring of the trailer to match the vehicle's connector so that adapter complications are avoided. Fewer connections are also generally more reliable. A 7-way junction box like # 277-000141 mounts to your trailer frame and includes a 7-way cord and plug. Simply cut off the existing trailer 4-pole connector and apply ring terminals like # 44-5310A to...

  • Will Hopkins Heavy-Duty Trailer 7-Way to 4-Wire Adapter # HM47065 Activate Brakes on Trailer
    The Hopkins Heavy-Duty Trailer 7-Way to 4-Wire Adapter # HM47065 is intended to plug in to a tow vehicle 7-way socket, take its lighting signals only (not a brake signal or 12V power) and route them to the 4-pole flat connector. When an adapter reduces the number of wires it also reduces the number of electrical circuits and therefore the number of functions. A trailer with electric brakes will need to have at least a 5-pole wiring harness (one more wire to provide one more function)...

  • 7-Way Recommendation to Replace 4-Way on a Trailer
    Sounds like you have a trailer that currently has a 4-way and a tow vehicle that has a 7-way. Based on what you said you are looking for the part # PK12706 would be what you would need. I attached a help article on trailer wiring for you to check out as well.

  • 5 Foot Long 4-Way Flat to 7-Way Flat Adapter
    Not exactly, but I can come up with a 5 foot long adapter that has a 7-way male on one end and a 4-way female on the other. Basically you would need the # 18045 and then to plug in the # PK12716 into the corresponding end and you would be good to go.

  • 7-Way to 4-Wire Adapter Cord With 8' of Length
    Yes, as the Hopkins Heavy-Duty Trailer Coiled Wire Adapter for 7-Way to 4-Wire Flat part # HM47065 is only 3' long, you will want to use the Wesbar Coiled Adapter 7-Way RV to 4-Way or 5-Way flat part # 787196 as this cord is 8' long. Both coiled adapters offer a 7 to 4-way conversion. I have included a video review of this product for you.

  • Available 7-Way to 4-Pole Trailer Wiring Adapters
    We do offer trailer wiring adapters that can allow connecting different wiring formats such as a 4-pole and a 7-way. But as you noted, if you convert 7-way vehicle wiring down to 4-pole trailer wiring you do naturally lose 3 circuits: 12V auxiliary power, reverse lights and trailer brake power. All such adapters are shown on the linked page. I suggest using a cable type adapter like # HM47065 since it provides strain-relief, unlike the solid adapters such as # PK12716.

I have linked a video review of this adapter for you. We have a lot of 7- to 4-Way adapters. Some have an extension and some do not. I have included a link to the options for you.

    As long as the 2016 GMC Yukon Denali has 4WD with a two-speed transfer case that has a Neutral and 4 wheel drive low setting, you can flat tow it with all 4 wheels on the ground behind the 2018 Allegro Bus. If the GMC has 2WD, it has to be towed with a dolly with the rear wheels off the ground. When flat towing or dolly towing, the battery does need to be disconnected. You can use a Roadmaster quick battery disconnect part # RM-766. The Roadmaster battery disconnect allows you to wire in...

To connect this type of trailer wiring to the 4-pole flat type used on the Pilot Oval LED Brake Light Trailer Hitch Receiver Cover # CR-017 you will need an adapter such as # HM47065, # HM47365 or # MT70086. These and all such adapters are shown on the linked page.

  • Tow Bar Wiring Recommendation for 2001 Ford Ranger
    For tow bar lighting for your 2001 Ford Ranger you would want the Hopkins Kit part # HM56004 which is a custom fit setup for your vehicle. The connectors plug inline with the taillight connectors on your truck and allows your RV to control them. If your tow vehicle has a 7-way you would want the part # HM47065 to use as an umbilical adapter to span distance between RV and Ranger.

  • Recommended Components For Flat-Towing 2007 Saturn Ion
    From my research, I found that the Ion can be flat-towed if it is not the Red Line model. When flat-towing any vehicle, you will need 5 items. You need base plates, a tow bar, safety cables, lighting for the vehicle, and most states now require a supplemental brake system. The base plates I recommend for your Ion is the Roadmaster EZ Base Plates, part # 523118-1. The tow bar I recommend is the Roadmaster Tracker Tow Bar, part # RM-020. Since you need to tow the Ion with the tow bar...

  • Available 7-Way to 4-Pole and 5-Pole Wiring Adapters
    Yes, a 4-pole flat type trailer connector can mate with a 5-pole flat. The additional circuit on the 5-pole side would obviously not be connected. But we do have 7-way to 4-pole cord-type wiring adapters too, similar to 7-to-5 adapter # A57CCB, such as # HM47065, # C57271 and # MT70086. We also have plug-style adapters such as # HM47570 that convert a 7-way to 4-, 5- and 6-pole, all in one product. All wiring adapters are shown on the linked page.

  • Brake Lights Not Working When 2013 Audi Q7 is Hooked up to Boat Trailer
    On the trailer side of wiring the stop signal is connected to both the left and right turn signals. Because your turn signals are working I don't believe that the problem is the Hopkins Adapter 7 Pole to 4 Pole with Tester and Cover # 47345. The problem is most likely that the trailer has a bad ground or the harness is being overloaded when you connect your trailer to your 2013 Audi Q7. The only way that the connector would be the issue is if it was damage in some way or if the connectors...

    It sounds like the magnetic kit you have uses a 4-Way flat connector and the truck has a 7-Way blade style connector. There is an adapter you can use. Several as a matter of fact. I have included a link to them for you to view. A simple option like # PK12716 is all you would need. But since you are flat towing, you may need some extra slack so going with a coiled adapter like # HM47065 may be the best way to go.

There is a specific procedure that must be followed, which is outlined in your owner's manual. From what I read online, the Jeep WJ (Grand Cherokee 1999-2004 model years) is a popular vehicle to flat tow. The WJ is lighter than later models, which makes it good for flat towing.

You'll also want to check your hitch to confirm its tongue weight (TW) capacity and to check your owner's manual to verify the truck's TW rating. Both the hitch and truck have to be rated for at least 500-lbs of tongue weight since both have to handle the combined weight of the bike itself plus the 51-lb weight of the Rage...

I recommend the Hopkins Heavy-Duty, Coiled Trailer Connector Adapter, part # HM47075. This connects to the 7-way on your Hummer and gives you a 4-way connector to connect the trailer to.
