Video Transcript for Hopkins Wiring - Wiring Adapters - 47549 Review

Today we're going to review part number 47549. This is the Hopkins Universal 7-Way Blade to the 6-Pole Round Adapter. This adapter will convert the seven way on your towed vehicle down to a six way round connector which will be on your trailer. It does include this nice dust cover that's connected to the adapter. When you're not plugging it into the six way you can put the dust cover on to help protect the terminals. This is impact and corrosion resistant.

It does have the nice easy pull grip. You can see that right here. You can just put it in there to unplug it. It does use the nice corrosion resistant tin plated terminals. One thing to remember when you go and plug this in to a six way, a six way on a trailer could be wired one of two ways. It could be either the center pin can be wired either as a hot wire or a hot connection for twelve volt connection, or it can also be ...

the center pin can be wired as a trailer brake circuit. Depending on what you need on your trailer what you could do is this will come wired with the center pin as a hot or twelve volt wire, and it's actually stamped on here center pin AUC/battery. It's letting you know that the center pin on here is wired as a twelve volt power connection. Now, if you do have a trailer that uses that center pin as a trailer brake circuit it is very easy . you can easily switch it. What you'd have to do is just take this apart and all you'd do is switch the blue and the black wires inside this adapter and then the center pin would be changed over to the trailer brake circuit connection.

That should do it for the review on part number 47549, the Hopkins Universal 7-Way Blade to 6-Pole Round Adapter. .

We had been having trouble with our other adapters, no brakes or intermittent brakes. This adapter fits better than any of the others ever have, great connection and is holding tight. I will be picking up some more of these. The only downside to me was they came on the value shipping which is rather delayed for us and I would rather pay to get it here more quickly. I was needing it and it was several days getting here. We ship a lot and I know shipping directly with USPS goes faster than that and is not expensive. 600691

Do you have a question about this Wiring?


  • Troubleshooting New Wiring on Trailer Causing Right Turn Signal to Activate All Trailer Lights
  • Since the issue didn't start until you swapped out the 4-Way on your trailer it would seem that the problem is on the trailer end, but normally this doesn't translate over to the vehicle. What could be going on though is that you have a bad ground on the trailer which is causing backfeed on your vehicle side of things. Checking the connectors themselves to make sure they are clean is always the first step. Using some dielectric grease like part # 11755 can help protect and prevent future...

  • Equipment Needed to Install Brake Controller on 2003 Lexus RX300
  • I'd be happy to help you with that. Beginning with the brake controller I'd recommend going with a proportional controller like the Tekonsha Primus, part # TK90160. A proportional controller can sense how quickly the tow vehicle is braking, and will send the correct amount of voltage to the trailer brakes so the vehicle and trailer stop at the same rate. Time delayed controllers will always send the same amount of voltage to the trailer brakes (according to how you've adjusted it) whether...

  • Turn Signals are Dim with Brake Lights Applied on Magnetic Tow Lights
  • It doesn't sound like to me that there is anything wrong with the lights or wiring. The turn signal and brake light are both carried through the same dual filament bulb. The circuit associated with the brake light will generally be brighter than the circuit for the turn signal. I recommend switching to an LED option which will make the turn signals much brighter when the brakes are applied in comparison to a set of magnetic tow lights with an incandescent bulb. For this we have the MaxxTow...

  • How to Replace a 7-Way Trailer Connector on a 1992 Nuwa Hitchhiker
  • I have attached the common wire colors on a 7-way for you below but as not all trailer manufacturers use the same wire colors and they could have been replaced at one point in time so it would be best to test them with a 12 volt battery. Once you attach each wire to the positive side of a battery that circuit should then light up and you will know which color represents which circuit. The other option you have would be to contact the trailer manufacturer with your VIN. I wish I could tell...

  • Troubleshooting Bent Pin on Trailer Side 7-Way Connector
  • It does look like one of the pins on your existing 7-Way may have been bent back into the connector. This isn't too uncommon and it would definitely cause the intermittent connection issues you have been having. If you aren't able to bend back the pin in question so that it can make good contact with the vehicle-side connector then your best option is indeed to simply replace the 7-Way. For this the Pollak # PK12706 will work well. You will just need to cut off your existing connector...

  • Testing the Center Pin On a 6-Way Trailer Connector
  • You will need to use a circuit tester, item # ALL640595 if needed, to test the pins in the 6-Way connector at the rear of your vehicle. Ground the alligator clip to the vehicle chassis and touch the test light to the center pin. If the light in the tester lights then the center pin is hot, 12 volts. If the center pin is for brakes it will only have power when the brake pedal is applied or when the manual brake lever on the brake controller is activated. In most cases, the center pin...

  • Coiled Flex Umbilical Cable to Join 7-way on RV to 6-Way on Flat Towed Vehicle
  • Hopkins offers a flex cable, part # HM47053 that sounds exactly like what you need. On one end, it has the 7-way plug that's compatible with your RV, and a 6-way plug on the other that would plug into your towed vehicle. I'll link you to some of our help articles that contain additional information about flat towing.

  • Brake Controller Installation on a 2002 Ford Explorer
  • To install a brake controller on your 2002 Ford Explorer, you will need to run wires from the rear of the vehicle to the front. I would recommend converting your 4-Way plug to a 7-Way, as this is the most common plug style. You can use brake controller installation kit # ETBC7 to do so, as it includes the 4 to 7-Way adapter, and the wiring, connectors, and circuit breakers you will need to complete the brake controller installation. The 4 to 7-Way adapter would first be plugged...

This wiring harness is designed to attach to Tekonsha brand brake controllers like the Tekonsha Prodigy P2, # 90885.

  • How To Change a Vehicle 7-Way Connector to a 6-Way Vehicle Connector
  • If you are trying to change the 7-way connector on your vehicle to a 6-way round connector you can use the Hopkins Adapter, part # 47549. This adapter will plug into your existing 7-Way and give you a 6-Way round connector. The center pin of the 6-Way side of this adapter is setup as the 12 volt power lead, but it can be changed if you need the center pin wired as a brake lead. If you were needing to change to a 6-Way square connector, you can use the above # 47549 adapter and add...

  • Trailer Brakes Lock Up When Using the 7 Pole to 6 Pole Adapter # 47549
  • The reason your brakes are locking up when you use the 7 Pole to 6 Pole Adapter, # 47549, is because there are two ways that 6-way round trailer connectors can be wired, as you may have already discovered. The difference is the pin for the electric brake output and the 12 volt power. It sounds like the 6-way connector on your trailer uses the center pin for the electric brakes. This adapter uses the center pin for 12 volt power. As you have noticed, this will apply 12 volt power to...

  • Your 2002 Chevy Silverado came wired with a factory 7-way so I recommend you use the Replacement Multi-Tow 7-Way & 4 Pole Trailer Connector # 74682. If that wiring connector isn't present, then I recommend hardwiring the plug using the Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket # PK11898. I've attached an article to help you with this wiring, but you will simply splice into the present wiring based on function. Then to adapt to your camper's...

  • If your F350 only has the 4-pole trailer connector, chances are that it is not equipped with the necessary relays that are factory installed when the vehicle is equipped with the factory tow package. The 7-way wiring harness, part # 118243 includes the necessary relays and fuses to activate the tow package so that the running lights will function for you. The relays would install in the large fuse box under the hood, and the fuses would install in the smaller adjacent fuse box. Your owners...

  • Recommendation for a 4-Way Flat to 5-Way Flat Trailer Connector Adapter
  • The Lexus 300 and Nissan Pathfinder use different wiring harnesses, but if they both have 4-Way flat trailer connectors, they will be pinned the same (function the same). The 5-Way trailer side connector will have an extra function at the pin furthest from the covered ground pin. This function is typically used on surge couplers that have an electric lockout feature. The corresponding pin on the vehicle side would need to be connected to the reverse light circuit for this feature to function....

  • Trailer Brakes On Camper are Humming
  • What you are hearing is the brake magnet being activated. If this is happening immediately upon plugging in the trailer, while the brakes on the truck are NOT being applied, it would indicate that something is wired incorrectly. Does the truck have a 6-way or 6 pin trailer connector? If so, either the connector on the vehicle or the trailer would need to be rewired. There are two accepted methods of wiring a 6-way connector. One method uses the center pin to carry the brake controller...

  • Troubleshooting a 2010 F-150 SuperCrew with Internal Brake Controller not Working
  • Since the trailer brakes are working with another vehicle, the trailer wiring is eliminated as a source for the issue. The first thing I would check is the adapter you are using. Trace the power wires for the trailer brakes back to the trailer connector to determine which terminal is the brake feed circuit. Once this is determined check the adapter to see if it is wired correctly to transfer the brake power from your vehicle to the trailer brakes. There are two different acceptable wiring...

  • Hitch and Other Towing Accessories Needed to Tow Pop-Up Camper With 2009 Kia Sedona
  • To tow your pop-up, you'll need a hitch, wiring, a ball mount, trailer ball, brake controller and a install kit for the brake controller. The hitch needed will depend on if your Sedona is the EX/LX or the base model. For the LX/EX model, I'd recommend the Draw-Tite # 75421. For the base model, go with the Draw-Tite # 75551. For the trailer wiring harness, use the Tow Ready # 118410. For a ball mount, use part # 2752. Your camper should have the necessary ball size stamped into the coupler...

  • A 5 pole round connector is really rare, with the 7-way, 6-way and 4-pole flat being the most common. Most trucks that come with an OEM trailer connector will come with a 7-way. A 6-way is sometimes found on horse trailers, and a 4-pole is the basic connector used for smaller trailers that supplies lighting circuits only. I've edited a photo for you showing an example of the plug and socket (or trailer and vehicle ends) of each of these connectors. I'd recommend fitting your truck out...

If you need to add a 4-Way, you would use # 118325.

If can you open up the existing 6-way connector on your trailer, take the housing apart and look at the terminals the wires attach to. In many cases, they will be labeled like what is shown in the FAQ article....

  • If your trailer's 6-way plug and your 6-to-7-way adapter # 47549 that you installed for temporary use are now stuck together you can try gentle twisting and flexing of the two parts as you pull on them. Summer heat can cause such items to become fused together since they usually have a snug fit to begin with (to prevent risk of accidental separation). There could also be corrosion on the parts' electrical contacts from trapped water that could be why they do not want to separate. You...

  • If it was a 4-pin connector with 5 wires then it is called a wishbone harness and would have 2 wires attached to the running light pin so you have one wire for each side of the trailer. Typically, on a 4-Way, the white wire is ground, brown is running lights, yellow is left turn/brake lights, and green is right turn and brake lights. On a wishbone 4-Way you would have a ground wire and then you usually see a brown wire with yellow stripe for the left side running lights and a brown wire...

You will need to check the vehicle owners manual and/or check the power distribution box lid to find the tow package fuses/relays in question. Add or replace the offending part and test it again. If that was the problem and it blows again then there is a short somewhere, most likely a bad ground which could be where the two connectors come together or at the trailer tail lights.
