Video Transcript for Hopkins Wiring HM48470 Review

Today were going to review part number HM48470. This is the Hopkins Endurance Multi-Tow seven, five and four-way flat trailer connector for the vehicle end. This heavy duty trailer connector socket right here has an outlet for the seven way right here, has an outlet for a five way flat and a four-way flat that can be plugged in right down there. Both of these outlets have the weather-proofed insulated lids to help cover the terminals. You can see this one has a very strong reinforced lid. On the inside has the internal seals for alternate weatherproofing.

This lid also has the seals in there. They do open 180 degrees on both of them for easier connections of your terminals. It also has this nice large rugged oversized hinge which will hold up very well. Now, this part number does include everything shown here, the connector, the mounting bracket, the rear cover that covers your connections on the back, a couple packets of terminal grease and the mounting hardware to mount it to the mounting bracket. So basically when you install this you just mount your mounting bracket to wherever you need to on your vehicle and then you would just line this up.

The four holes right here will line up with the four on the back and then you will use the mounting hardware. Put the screws through here and the nuts back here to tighten it down. Once you get it installed then you can run your wire through here thats on your vehicle and out here, make your connections and then basically this cover will just snap on. You just push it in and it will lock right into place, just like that and then youre ready to go. Now, I do also want to mention that sometimes it gets confusing on the very bottom.

We show a total of five terminals, so when you have five-way flat, like this one pictured here, the trailer will have the four open terminals and then the one ground terminal thats in rubber, all you would have to do is on this one, the ground would be the exposed terminal right here, so you just line the ground up with the housing and you just it in like that and thats how you make your connection, very simple. What gets confusing is sometimes people say, Well, if I have a four-way flat and theres five holes, what happens Its pretty much just the same way. What you would do is, I have an example here of a Hopkins heres a four-way. It has three terminals and then the ground thats coated in rubber. Same way, you just line the ground up, push this in and then three of the holes will line up.

The other hole on the very end would stay open. That causes no problem at all. So you can hook up a five-way flat or a four-way flat in that bottom terminal.That should do it for the review on part number HM48470, the Hopkins Endurance Multi-Tow seven, five and four-way flat trailer connector for the vehicle end. .

I could not find a 7 round with a 5 flat connector anywhere in San Diego. Most of the people I spoke with at trailer shops or RV stores said no one makes it only with a 4 flat connector. I just kept looking because I needed one with a 5 flat for my boat and didn't want to keep using my adaptor. I found etrailer and the rep I spoke with was very knowledgeable and said he had exactly what I was looking for and it was a great price. I will be always using etrailer for my trailer parts for now on. Thank you, Vito Lotta - San Diego 144089

I received the product quickly and in perfect condition the packing was excellant. I installed the connector easily and quickly. I consulted the Gm wiring diagram and als found the wires for all the 7 connections. I had a tight spot within the bumper edge, but managed to find short bolts to attach the bracket in old exsisting holes. The rest was easy attaching the connectors and making sure all wires were through the rear enclosure and tightening them down. I tested the 4 wire connector with my boat trailer lights and it worked like it was designed to do. I LOVE the versatility of this connector. Thanks!! Great product at a great price. 14869

Installed the Hopkins muti-tow 7, 5, and 4 way flat connector this morning. I ripped the original connector that was attached to the bottom of the hitch receiver off when I was 4-wheeling into the Doll House campgrounds in the Maze District of Canyonlands a month ago. So, I cut a hole in the bumper and mounted the new Hopkins connector, cut off the old broken connector mounting bracket, and connected the factory wiring to the new Hopkins device. Hopkins product installed easily, looks great, is now out of the way, and has the flexibility of multiple trailer connectors when required. I am pleased with the product. Attached is a photo. 133981

Had everything you need. Be careful tightening the terminals, they bend easily so you may short one to another. Otherwise good bang for the buck. I would buy again. 116423


After a year the connector is still working great. Just remember to close the cover for the 5 pin flat connector. Still feel good about it.

I had broken my factor connector on my 06 Tacoma, frankly due to a poor design placement by Toyota in my opinion, however I was not going to pay a premium $200+ price for a new OEM part and I wasn't planning to place it back in the original spot to only get broken again. This is a great replacement plus I no longer need a wire adapter. The unit fit perfectly in pre-cut hole that held my left tag light. Only had to drill 4 small holes for the bolts to secure to the bumper. Only pain was cutting the old wire and attaching it to the new connector, but that only took 10 minutes top. 116271

Installed: 9/12/2013 Jeep Wrangler Unlimited Installation of the plug was a quick and easy. The existing Warrior hitch has a tab on the side for a trailer wiring socket. Drill a new hole on the installation bracket (comes with the trailer connector) so the bracket on the hitch matches bracket on the trailer connector. Done deal. This is the only trailer connector I found which has the 7, 5 and 4 connector options. Flexibility is always a good idea when you are borrowing someone else trailer or renting. 99853

I am the purchasing manager for a company that fabricates and installs custom truck equipment. Usually our customers don't want the 7 way RV style plug. When they do want this plug, we always install the Hopkins model. It is a great unit, and also gives the customer 4 way and 5 way flat options as well. This is the one I use on my personal truck. Great product, and E trailer always ships fast and has everything in stock. Much better than our local trailer supply company. 179954

Part arrived quickly and was exactly as pictured. Installation on my 2008 Dodge Durango was a little tricky, as there is no easy place to install it. Luckily my buddy was able to drill holes in bumper next to the hitch and then tap them so we could attach the connector with screws. There is not much room for the connector to fit, but by bending the metal mounting plate slightly it worked perfectly. The chart included with the product made it easy to wire correctly. 150280

Great product - the overall depth is a bit deep and for my specific application I had some challenges finding a good mounting point (partially due to the depth of the adapter and partly due to the lack of solid mounting surface. The product itself is sold with a flexible five/four way plug (single plug accommodates both the four and five pin) that will not easily break. The seven pin plug has a fairly stiff cover that is spring loaded. Wiring was simple too! 30756

I bought this to replace a factory Jeep 7 point connector. I didn't figure out till I was done that the brackets were the same shape and I could have left the original on. It was very easy to install, even for someone as mechanically challenged as I am. The bracket that was included is a bit flimsy and there were no self tapping screws with it. Otherwise it was exactly what I needed. Less than 30 minutes to install 106389

Very well made, nicely designed. Note, if you mount this vertically, as suggested, a plastic cover is provided for the rear, and the unit may extend beyond your old bracket. My old bracket was a part of the original Hidden Hitch, and this extended beyond the old bracket. Because the rear plastic cover is NOT waterproof, it can be sealed with a small bead of RTV or similar sealant under the edge of the cover. 54217

Actually I had two (2) seperate order because i could not make up my mind as to how i wanted to wire the trailer and other accessories that I have. Anyway, both orders were packaged extremely well. Shipment/receipt was great; took a short timeframe from the time items were ordered. Only one problem. No one showed up to help install all the parts I ordered. Thanks for the products and the support! 36330

Looks good, seems sturdy enough. I had a little trouble getting the back cover on after squeezing all my wires through. The rubber seal for the wires kept getting stuck on my wires when I tried to slide it down, probably be a good idea to make sure they're all in a nice and tight bundle to make it easier. Haven't been able to try it yet, though everything seemed to work when I used a test light. 88699

by: John S01/12/2014

This seems to be a pretty nice plug. Makes it nice with the 4 way and 7 all in one. The lid has a pretty stout spring on it so it should keep the weather out. Fast shipping excellent service. 112601

This is a nicely built durable connector , the install was easy but took some time ...I pre wired it with a four blade male which plugged into the factory four blade female on my 2013 f150 ... just make sure your connection screws are tight , I added silicone to them so they dont back out ... Looks great and it is defiantly a nice piece of hardware , spring shuts tight and seals nice ... 120457

I like this trailer connection. It seems to be well made and it is reasonably priced. I received my order in a reasonable time as well. The installation was not difficult and the wiring diagram was clear and understandable. I really like the idea that I can now tow a trailer with just about any type of connection and it will work. 14028

Its exactly what I needed to rewire my truck (2002 F150). My only complaint is that once you snap all the parts together in the rear, its very difficult to take apart. I ended up breaking off one of the clasps while trying to adjust the wiring. It still seals in the wires and has a tight fit. I really like my setup now!!! 30096

Great plug. The rear cover has two clips to hold the wire cover on the back. If you attach the wire cover, don't try to remove it, brand new the clips break off. Very fragile. Other than that the plug is easy to install and wire and hold the trailer plug firmly. 11114

I occasionally need to tow trailers with both the seven and 4 way flat connection. This connector gives all connections in one unit which was easy to install and cosmetically appealing. A solid unit that works as advertised. I strongly recommend this product. 131104

Overall , great plug and decent design . The rear cable entry could be a bit better to make it more weatherproof but works ok as is . I would highly suggest using a dielectric grease and tinning the wires to prevent corrosion . 99570

I stripped some of the wires and found that the copper conductors are pretty stiff, I doubt you would be able to wrap them around the terminals of the connector. Using some crimp on ring terminals like part # 44-5310A or fork terminals would be your best bet.

  • Parts Needed to Add a 7-Way Trailer Connector to a 1998 Dodge Ram 1500
  • If your 1998 Dodge Ram came with a 7-Way and you need a replacement you can use Pollak 7- and 4-Pole Trailer Connector Socket, # HM40975, and Pigtail Wiring Harness, # PK11998 if needed. The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector, # HM48470, can be used as well but it is a hardwire connector meaning you would have to attach existing wires from the truck to the connector according to the wiring diagram I have linked for you. If the truck came with a factory...

  • Need a Vehicle 7-pin Round Adapter to Connect to a Boat Trailer 5-Pin Flat
  • We do offer several adapters for a 5 pin flat to a 7-way blade vehicle connection. If your van connection point is a 7-blade configuration then you can use the Optronics # A75TB. This is an adapter that will plug into a vehicle 7-way blade style connector and will attach to your 5-pin flat boat trailer wiring connector. If your van has a 7-way round pin vehicle connection pin, unfortunately we do not offer an adapter for that configuration. However, there is an option, and I recommend...

  • The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector # HM48470 is a combination 7-, 5- and 4-way trailer socket for a tow vehicle that connects to the vehicle through screw-down wire terminals on its rear.

  • Replacing a 7-Way Trailer Connector on a 2008 Nissan Frontier

  • Replacement 4 and 7-Way Trailer Connector for a 2000 Ford F-350
  • You can use the Hopkins 4/7-Way connector # HM48470. All you will need to do is attach the wires from the old connector in the same places on the back of this connector then mount it where you want it. No other wiring harnesses are needed. The replacement 7-Ways we have for a 2000 Ford F-350 that also have the rectangular plug do not have a built-in 4-Way. We have # C55243 and # 118243. You could use one of these and then use an adapter, # HM47570. If the truck came with the factory...

  • Does Hopkins Endurance Multi-Tow Trailer Connector Adapter, # HM47570 Come with a Mounting Bracket
  • The Hopkins Endurance Multi-Tow Trailer Connector Adapter, # HM47570, is meant to plug into a 7-Way trailer connector that is already mounted on the back of a vehicle so it does not come with a bracket. The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector, # HM48470, does come with a mounting bracket. The only difference between this connector and the first one is that it does not have a 6-Way function. I have included a link to the installation details for this connector...

  • How To Install A 7 Way And 4-Way Connector To Factory 7-Way On A 1995 Ford F-250 SuperCab
  • The Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector, part # HM48470, would have to be hardwired to your existing wiring harness. If the 7-way you have on your 1995 Ford F-250 SuperCab is a plug-in connector you will need to sever the wires on the back of the connector. Then, attach each wire from the factory harness to the screw, for that same function, on the back of the Hopkins connector. If you have a plug on your 1995 Ford F-250 SuperCab wiring harness that matches...

  • Brake Controller and 7-Way Recommendation for a 2010 Dodge Grand Caravan
  • The absolute easiest way to upgrade your 4-way to a 7-way would be to return the part # HM48470 and get the part number # ETBC7 instead. This comes with absolutely everything needed to upgrade the 4-way and make it fully functional, including the installation of a brake controller and running the power line to use for maintenance charging the battery of your trailer. A brake controller by itself would not come with everything needed to install in a vehicle. I attached an install video...

  • Wiring of Trailer Connector Adapter on 1995 Toyota Pickup
  • Although the wire colors can vary by vehicle or trailer manufacturers, there is one standard way to wire a 7-way blade style trailer connector. If you are looking at the front of the connector as it is installed on the rear of a vehicle, beginning with the top pin just right of center and continuing on clockwise, first pin carries 12 volts for any trailer accessories needing power, the next pin carries the right directional/brake light signal, the next pin would carry the output from the...

  • Removing European 7-Way and Installing US 4/7-Way on a 1999 Land Rover Ranger Rover
  • A European 7-Way does the same thing that a US 4-Way does so the problem you would run into is that you would still need a converter of some kind because the European 7-Way has separate brake light and turn signal circuits. US trailers have combined turn signal and brake light circuits. What you could do is cut off the European 7-Way. Then use a circuit tester such as # 3808 to test the wires to determine the functions. Then you could use converter # 119192 and 4/7-Way connector # HM48470....

  • Converting 4-Pole on 2005 Chrysler Town and Country to a 7-Way Trailer Connector
  • Your best bet for an easy install would be to use the 4-pole to 7-way adapter, part # 37185. The adapter will plug directly into the 4-pole supplied by your T-One connector, leaving 4 remaining wires. The white wire would be grounded to the vehicle frame, the purple wire would tap into the reverse lamp circuit (if needed), the black wire which supplies a 12-volt accessory power circuit to the trailer if needed is ran to the battery and the blue wire carries the output voltage from a brake...

  • Wiring Options for a 2009 Chrysler Aspen Towing a Boat Trailer with a 5-Way Flat Trailer Connection
  • Yes, the Tow Ready Custom Fit Vehicle Wiring for the 2009 Aspen by Chrysler, item # 118390, is the correct wiring harness for your Aspen and you will need one other item to complete the wiring to lockout the brakes on your boat trailer surge coupler. You can go one of three ways for this wiring. The easiest way in my mind is to install the # 118390 T-One and then splice the 5-Flat Vehicle End 72 inch Wiring Harness, item # 20016, to the 4 like wires left by removing the 4-way vehicle...

  • 7-Way to 5-Way Trailer Adapter Does Not Operate Right Turn and Brake Lights, 2003 Chevy Trailblazer
  • The adapter that you purchased may be wired or configured differently than your trailer. You will want to plug in the adapter and test the pins on it for function. A traditional 5-Way flat will have the far left pin as electric brakes or for an electric lock out. Since your trailer has surge brakes, it probably has an electric lock out so this pin would need to be connect to the reverse light circuit on the vehicle. The pin next to that is for right turn and brakes. The next pin is left...

  • Turn Signal Not Working when Using Brakes and Using Hopkins 40955 Wiring Kit

Make sure all your ground connections are good and clean. There will be a ground connection coming from the trailer connector to somewhere on the trailer tongue and each of your trailer lights should have a ground connection through either a ground wire ran to the trailer frame or grounded through a mounting stud on the light...
