Video Transcript for Hopkins Wiring - Wiring Adapters - HM47570 Review

Today we are going to review part number HM47570. This is the Hopkins Endurance Multi-Tow Trailer Connector Adaptor. This trailer adaptor will change your vehicle 7-blade connector on your vehicle to either a 6-way connector or the 4 and 5-way flat connectors.This is built with this oversize lead hinge, which is built the last and it also allows the lids to open, as you can see, 180 degrees to help in simple connections. It does have internal seals for ultimate weatherproofing. It does come with this dielectric grease packet, so when you do and put your or plug your plugs in you can put the dielectric grease on that will help the connection and keep any corrosion from forming around your connectors. This part does come with a 3-year warranty. The main feature about this which is really nice is it comes with this quick-change plug right here, and what that will allow you to do is when you go to do a 7-way connector if you are going to go from 6 or 7-way to a 6-way, on a 6-way connector there is actually two ways that a 6-way can be wired and basically it has to do with that center-pin.

The center-pin can be wired either for the as a 12 volt hat design or it can be wired for the trailer brake connection. What you want to make sure is that when you plug your 6-way in that center-pin will match whats on your trailer.Otherwise, if its wired, if that center-pin is wired for a straight 12 volt power, if you go to plug it in your trailer and it needs it for trailer brakes it will lock the brakes on your trailer. The easy solution to that with this adaptor, which is nice, is youll just take this quick-change plug, and if you just pull up on it, and you can see there is two connectors and two wires, if you just rotate it 180 degrees plug it back in, just like that, that has changed your center pole connector. In other words, it will change it from the 12 volt power to the trailer brake power or vice versa, whichever way you needed it.So there is no rewiring necessary. It used to be when you did an adaptor you would have to rewire that center-pin to whatever you had on your vehicle or on your trailer, now with this quick-change plug it makes it very simple changing that center pinges by turning it and plugging it back in, that will reverse what that center-pin would do. This does come with a 3-year warranty and that should do it for the review on part number HM47570, the Hopkins Endurance Multi-Tow Trailer Connector Adaptor .

This was everything I needed it to be. I worked great, and the interchangeable center prong allows me to use it on two different trailers. I'll buy from these guys again. 572719

As advertised. Well made too. The spring for the cover/seal is robust and I don't expect it to weaken. The adapter works perfectly with my Pollack 7 pin outlet and captures on the retaining clip as both are desiged, so the adapter is securely in place down the road. The ability to reverse polarity on the 6 pin trailer brake set up is really nice, but I suggest to have a pair of needle nose pliers handy to stuff the wires back in the housing so you can get the two terminal plug re-inserted. A bit to fiddle with, but once you set it up for your own trailer, you never would mess with it again. Good product. You wont be disappointed. 130037

It's an excellent product, them other cheap 7 to 6 way don't let the trailer brakes work with out changing wires. This one quick plug to change from power brakes to aux. Plus it has the 5 way and 4 way. It's got them all in one. Excellent product. 267660

I needed an adapter for my electrical towing harness so the that I could use a 5-Way connector on my 7-WAY plug. On line, I found and ordered Item No. HM47570 "HOPKINS ENDURANCE MULTI-TOW CONNECTOR ADAPTER - 7-WAY to 6-WAY, 5-WAY or 4-WAY." When I received the product, I was really stoked, it was exactly what I needed and what I had been looking for! I tried it on for "size" as you might say and it's going to work like a charm. I will send some photos later when I'm done with the installation! No time right now. . this coming weekend! 71688

This thing is a beauty, if you have a 7 pole trailer wiring kit, this is a must have. You will never need another set of adapters because you're covered from 4 pole to 6 pole with the adapter and 7 pole when you remove it. Can't go wrong, great quality and the reverse mode for hot circuit/trailer brakes is a great touch. 10/10 364610

Ive owned this little unit for about a year now and havent had a chance to use it very much. However, when I tow my boat or anything else, I dont have to worry about not being able to connect it. Its a well built dependable unit and I would recommend it to anyone that tows a lot.

My '92 GMC Sierra had a 6-pin trailer harness connector and I'm going to be pulling a pop-up camper in a few weeks that has a 7-pin connector. I originally ordered a 47435 6-Pole to 7-Pole Trailer Wiring Adapter. After thinking about it for a day I changed my mind and ordered a HM48470 Hopkins Endurance Multi-tow 7-way, 5 & 4-wire Flat Connector to mount in the bumper and a HM47570 Hopkins Endurance Multi-tow Connect Adapter - 7-way To 6-way, 5-way and 4-way. The HM48470 will allow me to pull the pop-up as well as giving me the 4-wire flat connector that I need for my boat trailer. I bought the HM47570 adapter just to cover all the trailer wiring needs I might run into. I really like the fact that the 47570 adapter has the quick change plug to cover both wiring arrangements for 6-pin trailer connectors. I placed the original order Saturday evening and the second order Sunday afternoon. Monday morning, I called etrailer.com to try to cancel the first order and was told that both orders were already boxed and on the way the shipper. I had no idea that they had people there to pull and box orders on the weekend. I asked about returning the first order when it arrived and was told by Helen M that it would be no problem at all. I have been extremely pleased with my purchase experience with etrailer.com. Everyone I spoke with there was very knowledgeable and I will not hesitate to go directly to them for my trailer and towing needs in the future. 543065

This product really is just "plug-and-play". I have a 2012 Chevy Traverse with the strongest towing package available for that vehicle. It comes with a 7 way receiver. I tow a 1998 viking 2490 pop-up camper that came with a standard 4 pin which I rewired to a 6 pin round adapter so that I could add a battery to the trailer and charge it while I was going down the road. It works great! No problems whatsoever. This is actually the second HM47570 that I have owned because I backed the first one into a high snow bank and broke it. 343779

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. 305042

  • Integrated Brake Controller, Hydraulic Brakes and Trailer Wiring for Boat Trailer
  • If your boat trailer has a mechanical surge actuator coupler like # 8605001 then no trailer brake controller is required. The inertia of the trailer moving forward provides the compression to push hydraulic fluid to the brakes. If on the other hand you have an EOH system, electric-over-hydraulic, such as with an actuator like # HBA-12 for drum brakes or # HBA16 for disc brakes, then you DO still need a trailer brake controller to deliver the electrical signals to the actuator, which...

  • 7-Way to 5-Way Adapter To Add Rear Light Strip On 2019 Nissan Frontier
  • I took a look at the factory wiring on the 2019 Nissan Frontier and factory tow plug wiring is located along the driver's side frame rail behind the rear bumper. Since the connectors are square the Curt part # C56584 cannot connect to the factory wiring in the Frontier. The Curt harness is designed to plug in line with the 7-way on the vehicle but the factory 7-way on the Frontier is not 2 pieces so it does not come apart to accept the Curt harness.

  • Unfortunately I can't see the photo as it didn't come through, but your description helps me understand what you need. It is not uncommon for the brake output and 12V lines to be switched on the 6-way. I recommend the Hopkins Endurance Multi-Tow Trailer Connector Adapter - 7-Way to 6-Way, 5-Way or 4-Way # HM47570 which has a quick change plug to simply swap those connections as needed. Unfortunately we don't have a Mighty Cord brand product that works in this same way, but I think you...

  • Troubleshooting Trailer Brakes Not Working When Using Wiring Adapter

This is why, as an example, the Hopkins 7-Way to 6-Way Adapter # HM47570 offers the ability to change the function assignment. 6-way round wiring setups can be configured with the brake circuit or the 12V power circuit on the center pin.

  • Adapters like # 37385 and # HM47570 are convenient and can work fine for the short-term but for long-term reliability you are really better off replacing the connector on the trailer to a 7-way that matches your truck with no adapters - or their potential problems. Those extra connections can mean more chances for corrosion. You can easily test your truck's 7-way using a circuit tester like # ALL640595.

  • Why are My Brakes are Always Activated with a 6-Way Connector and a Curt Brake Controller
  • There are actually two different ways they will wire 6-ways. Basically the difference is between where the 12 volt power source is relevant to the brake output circuit. The only difference between one setup and the other is that the 12-volt power and brake output circuit is swapped. So all you should have to do is swap the brake wire with the power wire and everything should work fine.

  • We do offer replacement connectors that will work with your OEM wiring harness on your 2008 Ford F-250. If you just need the replacement 7-pole connector, I recommend part # PK11893. This is an exact replacement for the OEM connector on your truck. If you find the vehicle side of the harness was damages, I recommend part # C55242. This plugs directly into OEM tow package wiring harness and requires no cutting or splicing of wires. To get a 6-pole connector on the rear of your...

  • 5-Way Recommendation for Trailer for Installing Reverse Lights
  • What's great about 4-way flats and 5-way flats is that they can fit each other without the need for an adapter. So what would be your best option is to use the part # HM47570 in the 7-way of your truck and then add a 5-way part # W002290 to your trailer. Basically you would want to cut off the 4-way wires short and then leave the 5th reverse light wire long to run it back to the reverse lights. The remaining wires would wire directly to the 4-way wires the trailer currently has.

  • Using E-Z Mount Tow Light Kit, # EZT20B, with a Tow Dolly Already Connected to RV Trailer Connector
  • The Roadmaster Tow Dolly with electric brakes, # RM-2000-1, also already has lights on it which is why they did not provide an additional socket for lights. It also has a 4-Way flat trailer connector with extra blue wire for the electric brakes and not a 7-Way. Since your RV has a 7-Way, what I recommend is to change the connector on the tow dolly to a 7-Way, # PK12706, and then you can use the Hopkins mutli-tow adapter, # HM47570. This connector will allow you to plug in the 4-Way...

  • Adapter for 4-Way Flat Vehicle Connector to 6-Way Round Pin Trailer Connector
  • If you only need the basic lighting functions provided by the 4-Way (left/right turn, brake, and running lights) all you will need to do is plug the 4-Way end of the Adapter 4 pole top 6 pole, # 30637, into your vehicle 4-Way. The trailer 6-Way will then plug into the 6-Way receptacle on the adapter. You will also need to ground the white wire on the adapter to the vehicle frame at a clean and corrosion free metal surface. The remaining wires (blue for electric brakes and black for...

  • Brake Controller and Trailer Wiring Installation on 1997 Jeep Grand Cherokee
  • To install a brake contorller on your 1997 Grand Cherokee, you'd first need to install a 4-pole connector, using the Tow Ready # 118349. How you'd proceed next will depend on the connector use on the trailer you'll want to pull. I'd recommend using a 7-way because it's the most common. You can always use an adapter like part # HM47570 to convert it to anything else you'd need. To actuate the electric brakes on the trailer, you'd need a brake controller. I'd recommend going with a...
