Video Transcript for Hopkins Wiring - Trailer Connectors - 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. .

This is a Great product ! I built a trailer tester which is self powered and pretty much self explanatory on the way it operates. Using this connector gives the flexibility or connecting to a 4,5 or 7 way plug !


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.


Exactly what we had been looking for. Now I can hook up multiple trailers with different connectors and all the electrics on each trailer works. I mounted mine directly to the receiver hitch frame. The biggest challenge for us was routing the backup wire from the taillight housing, through the body of the truck to the connector. the rest went together fairly easily. Seems to be pretty solid and looks much better than the loose pigtail connector it replaced.


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.

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.


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.


The connector interfaces very well with my XC90 and there is no drilling or advanced skills needed. Everything went together very well.


This Hopkins 7,5, and 4-way trailer cord socket was delivered quickly and fits my needs for all my trailers. It came with all fasteners and complete instructions in the package and etrailer videos. I recommend this product and as a vendor.


I ordered the Tekonsha Electric trailer brake control and the Hopkins connector. It met my expectations. And easy installation. I have ordered from etrailer several times and they are professional in every way.


This was not made for my truck. I knew that before purchasing. I welded two bolts to my bumper to attach it and I am pleased with how it looks. Wiring was easy!


I used this to complete the factory 5th wheel wiring in my 2015 Silverado 3500HD. Gives me a professional installation for my 5th wheel RV.


Easy to wire and connect.


Build quality seems better than the base Hopkins product I had used before. Installed it in a mounting box (18159) on my Curt round tube hitch.


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.


What else can I say, it worked great!


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,

It's a connector!

We got this connector
to wire our small teardrop with an RV 7-blade for underway charging and reverse lights. It's well built, seals well when not in use, and does its job just fine. We did not lube the contacts, but so far no visible corrosion. The 4/5 flat connector is a nice bonus - keeps us from needing to carry along an adapter.

If you're installing it in a new location there are two things to remember: make sure you have enough depth at the installation point to allow wiring to run clear, and use a REAL bimetal hole saw if you're installing it in a metal bumper.

Would use again.


Been working great. I silicone the end where the wires come in so that I wouldn't get any moisture in there.

still working fine

Good product. 5 pin cover could fit tighter, but over all makes trailer wire hook up easy and trouble free. No more searching for adapters.

Great product fast shipping would do business again here


This receptacle should come standard on all pickups and SUVs!! The seals keep out almost all of the water and grime. The spring-loaded cover acts as somewhat of a keeper for whatever plug is inserted in the large receptacle. The versatility of hooking up to old and new boat trailers, plus any equipment trailer the local rental yard can throw at me, is amazing! I still carry a couple of adapters, but never need them. Installation takes about 15 minutes. Be sure to use the included terminal grease.


The Trailer plugin was a replacement for a cheaper one, that was mounted below the bumper, next to the tow hitch. This one is mounted in the bumper, between the license plate lamp and the license plate, out of the way of being damaged. Great plugin. ( but drilling the bumper was a pain, but worth every bit of time). This is my third order from E-trailer. Great Service and looking forward to my next order.


Trailer light connector arrived in a reasonable time and is as represented. I will like the convenience of having both the flat and RV style plugs, but it does make the receptacle a bit bulkier than just an RV connector. For me, finding a suitable mounting location that will not put it as the lowest thing in back is often a challenge. I don't like making big holes in the bumper, esp. on my pristine old truck bumper. etrailer used to offer a connector box that secured to the hitch square tube with a hose clamp. I bought one for use on a motorhome and it worked well, but I could not find it offered any more.


This plug is awesome! Using the bottom 5 pin plug on the bottom plug works great on my utility Trl, the other plug I have wired for my other trailer with brakes, it definitely works great with no adapter's no matter what the trailer on mine I'm pulling, would definitely recommend this if you need a great plug!


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.
