Video Transcript for Hopkins Wiring - Wiring Adapters - HM47075 Review

Today we're going to be reviewing part number HM47075. This is the Hopkins Heavy-Duty Coiled Trailer Connector Adapter, 7-way to 5-way Flat. It can also be used with a 4-way flat connector. This is a heavy-duty coiled cable. It's got the weather-proof jacketing so the cables or the wires inside the jacketing are going to be protected from the elements. It's completely sealed so no wires are exposed. Here on the 7-way it's going to have nice finger grips that's going to allow disconnecting the cord to be very simple and easy. On the inside of the connectors it's going to feature tin-plated terminals and that's for ultimate corrosion resistance. When fully stretched out this cable is going to measure 3' in length.

It's going to have the 7-way RV blade on one side and the 5-wire flat connector on the other. That's where the stop, tail and turn function wires, those wires are going to be constructed of 18 gauge wire. For the ground wire and the reverse wire those are going to be constructed of 16 gauge wiring. Please keep in mind that this works with a 4-way flat connector plug on your vehicle, as long as it does not have any unusual housing that might prevent the connection from being made. The flex coil adapters are going to provide increased durability and the additional length that may be necessary to reach between the two vehicle's socket and the trailer or towed vehicle's plug. It's also a really nice feature because when it's not in use you can see that it coils up, folds up really nicely.

It can easily be stored in a storage compartment. That way you can always keep it close at hand and just pull it out and use it when you need it. That's going to do it for today's review of part number HM47075. This is the Hopkins Heavy-Duty Coiled Trailer Connector Adapter. .

by:

This is a robust connector and just the right length -- not so long that it drags on the ground and long enough to keep from pulling trailer wiring during turns. It is a heavy duty connector with heavy insulation that should wear a long time. 178119

Bought this adapter because my "new to me" Ford F150 had a 7 way connection and my boat trailer had a 5 way flat... Product arrived just as advertised, appears to be high quality, and took about 5 seconds to get my boat trailer and new truck hooked up. All of the lights on the trailer worked great, and I didn't have to run a wire from the reverse light on my truck ( which you would need to do if going from a 4 way flat to a 5 way flat in order to disengage the surge brake on the trailer)... Very good product, fast shipping! Thanks again guys for the help! JB 125483

Ask the Experts about this Hopkins Wiring

Do you have a question about this Wiring?


  • Custom Fit Parts Needed to Flat Tow a 2016 Chevy Equinox
  • Yes we do. The Hopkins tow bar wiring kit part # HM56108 is a custom fit wiring harness for your 2016 Chevy Equinox that will allow your RV to connect to it and control the taillights. I attached an install video for you to check out as well. For an umbilical connector to go from the 4-way of this harness to the 7-way on your RV you would want the part # HM47075. You will need a few more components to flat tow your vehicle though. For a base plate kit we have the Blue Ox part # BX1689...

  • How to Make a Charge Wire for Flat Towing Vehicle with Tow Vehicle with 4-Way
  • To trickle charge the battery on your vehicle you will need to use a # 37185 to convert the 4-way on your tow vehicle to a 7-way. You will need to route the purple wire of this 7-way to the positive side of your battery on your tow vehicle through a circuit breaker like part # 9510 and 10 gauge wire like part # 10-1-1. Now for an umbilical to go from the 7-way to a 5-way you will want to use the part # HM47075. You will then need to use the part # 47515 to convert the 4-way on your toad...

  • Recommended 4-Way Connection Between Towed Vehicle and Motorhome
  • The only real advantage of the 4 round over the 4 flat trailer connector is the clean look of the connection point and the protection from elements when not in use. For instance the Pollak Heavy-Duty, 4-Pole, Round Pin Socket, Concealed Terminals - Chrome - Vehicle End # PK11410 has a clean finished look on the front of a towed vehicle and will protect the connection from dirt and debris with the spring loaded cover. Many people like the connection between the motorhome using a harness...

  • What Is The Difference Between These Flex-Coiled Wire Adapters by Hopkins - # HM47025 And # HM47075
  • These Hopkins wire adapters, Item # HM47025 and Item # HM47075, have similar functions. Both are heavy-duty, coiled cable with weatherproof jacketing. Both have easy-grip connectors and light up when connected. Both are 3 foot when stretched. Both adapt a 7-Way connector to work with a 4-Way or 5-Way flat connector on a trailer. One difference is that the The Hopkins Endurance Adapter, Item # HM47075, has a 3-year limited warranty. I have attached videos for you to check out.

  • 7-Way to 4-Way Adapter Recommendation for 2015 Chevy Suburban
  • Yes, you would want the part # PK12716. This will plug right into your 7-way and will provide you with a 4-way connection for your trailer. I attached a review video for you to check out as well.

  • Can 10 Gauge Wire be Used to Create Charge Wire beween Tow Vehicle and Toad
  • Using 10 gauge wire to make a charge wire for your toad vehicle is totally fine and actually very cost effective. We sell double bonded 10 gauge wire with part number # 10-2-1 (sold by foot) which would work well for this as the two wires are bonded together. You would not have to worry about overcharging at all either. The tow vehicle's alternator already has a voltage regulator that will keep the voltage in a healthy range.

  • Will a 4-Pole Flat Trailer Connector also Fit this 5-Pole Flat
  • Most standard 4-Pole flat connectors will fit this 5-Pole flat connector. There are quite a few options as far as adapters that you could use. I have added a link to all the 7-Pole to 4-Pole adapters we have. One in particular has both 4-Pole and 5-Pole connectors, part # 37385. We also have a coiled version of the part you were looking at, part # HM47075.

  • Is there a 7-Wire Hopkins Flex-Coil Cord without Trailer Connectors Attached
  • There is a 6-wire Flexo-Coil cord, # RM-1046-R, with just the wires but there is no 7-wire option. There is also a 4-wire version, # RM-1064-B. The # HM47075 cable is only going to have 5 wires inside since the one end can only be used on a 5-Way or 4-Way flat trailer connector. The wires inside the 6-wire # RM-1046-R is 14 gauge. This is not the ideal size for brake or 12 volt line. You could just use jacketed 7-wire, # DW04914-1 which has 6 wires that are 12 gauge and 1 that is 10...

  • Recommended Parts Needed To Flat-Tow 2013 Honda CR-V
  • When you flat-tow your 2013 CR-V you will need 5 items. You need base plates, tow bar, safety cables, lighting for the CR-V, and most states now require a supplemental brake system. I have attached a link to a helpful article that explains flat-towing you can check out. I recommend Falcon All Terrain Tow Bar, part # RM-522. The adjustable arms on this tow bar allow you to easily attach and release your CR-V. That is the advantage over the Falcon tow bar, part # RM-520. Both of these...

  • We offer a range of trailer wiring adapters to let you join a vehicle with one connector type to a trailer with a different connector. The link provided will show you all options for adapters that convert from a 7-way blade-style connector to a 5-pole flat style connector. You can use a non-wired plug-type adapter like Optronics # A75TB, or if you prefer a wired-type adapter to give you a bit of slack you can use Optronics' 16-inch adapter # A57WB.

  • Function of Center Pin on a 7-Way RV Blade Style Trailer Connector on a 2003 Toyota 4Runner
  • No problem, I will be happy to help. The 7-Way you have is called a blade or RV style. The center pin will either be for reverse lights or auxiliary 12 volt power. If the trailer does not have reverse lights or does not need a second 12 volt circuit then it would not matter if the adapter had it or not. If the trailer has an electric reverse lockout feature, common on boat trailers with surge brakes, then you would need that center pin in the adapter and the center pole on the vehicle...

  • How to Install Brake and Tail Light Trailer Hitch Receiver Cover # CR-007A on 7-Way
  • The Pilot Brake and Tail Light Trailer Hitch Receiver Cover # CR-007A that you referenced has a 4-pole flat trailer connector for making its electrical connection to your Silverado. You can use an adapter like Pollak # PK12716 to allow connection to your Silverado's 7-way trailer socket. If you want to add some length for stress relief you could instead use the Hopkins Heavy-Duty Coiled Trailer Connector Adapter # HM47075.

  • Can a 4-Way Flat Vehicle Connector Connect to a Hopkins, Trailer Adapter 7-Way to 5 or 4-Way Flat
  • Yes, you can plug a 4-way flat plug into a Hopkins Heavy-Duty, Coiled Trailer Connector Adapter - 7-Way to 5-Way Flat or 4-Way Flat, part # HM47075, as long as the 4-way flat plug on your vehicle does not have any unusual housing that might prevent the connection from being made.

  • Can 7-Way be Used for Lighting Kit with Separate Turn Signal and Stoplights
  • If you have a 7-way it should have the reverse light circuit on the center pin. Now the brake light circuit will not be separated out from that but you can use the # C56196 wired to the wires of the 7-way to get the circuit isolated.

  • Wiring Recommendation For Flat-Towing 2004 Toyota Tacoma To Provide Maintenance Battery Power
  • In order to provide a maintenance charge to your battery on your Tacoma when it is being towed you will need a couple things. The first thing you need is to determine which pin on the 7-way at the back of your RV will provide the 12V power you need. Then you can use an adapter like part # HM47075 to attach to the 7-way on your RV. This has a 5-way on the trailer side of the adapter. You then need to find which pin on the HM47075 when plugged into the RV has the 12V power. You may need...

  • Recommended Trailer Brake Controller for 2008 Hummer H2
  • Starting with the brake controller itself I recommend the Tekonsha Prodigy P2 # 90885. This is an excellent proportional controller that features an easy-to-read digital display, continuous diagnostics that will alert you to any potential issues, and 3 boost level settings so you can fine tune the trailer braking. I have attached a short video demonstration on this unit that you can check out as well. The 2008 Hummer H2 should have come equipped with a factory plug for a 7-Way connector....

  • Since the owner's manual on your 2003 Hummer H2 states it has a universal 7-way connector on the back, we have an adapter that will work fine for you. 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. As long as the 4-way connector on the trailer you are renting has the standard 4-way flat connector attached, using the # HM47075 should take care of...

  • Recommendations for a 7-Way to 4-Way Coiled Extension to Flat Tow a Jeep Liberty Behind a Motor Home
  • The Hopkins Heavy-Duty, Coiled Trailer Connector Adapter, # HM47075, measures 3 feet long when stretched. This will most likely not be long enough for most flat towing applications unless the 4-Way end on the vehicle has some slack that you can pull out. You could just add a 4-pole loop, # 18045, which will provide another 60 inches of length. There is also a 48 inch loop, # 18044. A longer coiled cable is not available unless you use # RM-1064-B (8 feet long) and then wire in 4-Way...

  • Availability of 32 Inch Long 7-Way to 5-Pole Trailer Connector Adapter
  • The Hopkins Heavy Duty Coiled Trailer Connector Adapter, part # HM47075 should fit your needs very nicely. When stretched, the cable measures 36 inches long. If you were looking for something that did not have a coiled cord, an adapter could be constructed using a 7-way vehicle end plug, part # PK12706 and a 5-pole vehicle end, part # 20016. You could also use a 3 foot length of wire loom, part # 459075-1 (sold by the foot) for a neater appearance.

  • How Do I Wire a 2005 Toyota Tacoma for a Brake Controller and 7-Way
  • This adapter will not provide the additional wiring needed for adding a brake controller. This product steps a 7-Way down to a 4/5-Way, not the reverse. What you need instead is a 7-Way Wiring kit like part # ETBC7. If the trailer connector you have on your Tacoma is the factory installed connector, it is actually a 4-Way connector. You will plug the 4-Way on the van into the ETBC7 harness, and like that, half of the functions are wired. There are 4 loose wires on the 7-Way that...

Then you would need to use 4- and 7-Way installation kit # ETBC7. This provides the 7-Way while retaining the 4-Way as well and the accessories needed to install it. An all in one that comes with the 4-Way with tail light connections and a 7-Way ins not available. I have included some links that explain the ETBC7 installation. If...

  • To connect the 4-way from the Tail Light Wiring Kit # RM-155 on your vehicle to the 7-way on your 2011 Tiffin RV, you will need to use the Hopkins Coiled Trailer Connector Adapter # HM47075. This adapter will plug into the 7-way round connector on your RV and provide a 4 and 5-way plug on the other end.
