Video Transcript for Tow Ready Universal 4-Pole Mounting Bracket Review

Today we're going to be taking a look at the Tow Ready 4-Flat Universal Mounting Bracket, part number 118149. This is a bracket mount that's going to clamp around your four-way connector and zip tie around your trailer hitch or vehicle bumper to provide a sturdy fixed location for your wiring. Here's what our four-pole bracket's going to look like once we get it installed. It's a nice clean look. Everything's provided that we'll need to get it mounted in place here. It's just going to give us secure location.

In this case, kind of tucked in a way a little bit to keep it maybe out of some of the elements and things like that. Now when ready for use, all you have to do is just pull your cap off the end there. Easy to do. When you're done, just slide your cap back on. Clean up the look of the truck so we don't have the wires hanging down here and running the risk of potentially hanging those on something or dragging them down the road. Now to do our installation, we're going to find our four-pole trailer connector.

As you can see, the reason we use something like this bracket is right now we just kind of get it twisted and spun around here. There's not a lot of rhyme or reason to how we can connect this. What we're going to be able to do is mount this up here in a nice secure location. We don't have to worry about this hanging down and potentially getting snagged on something or maybe bouncing down the road behind us, which I'm sure somebody has seen. And then it just kind of grinds off the end of it ...

so gets it up nice, high and secure. Now to install, we'll take our top side. This is going to be the side that's got the grooves that run down. Those are going to space our wires. As you can see our dust cap, the cover for that, it's got a little notch for it to fit into. Bring in the lower portion of our cover.

That's going to click in the two notches up there and we'll bring it around and click it in here on the other side, just like that. Now let's bring in our Philip screws. We'll tighten those down. These screws are provided for you so you won't have to worry about having them or supplying them. You see how there's still a little wiggle and a little play on our plug here To cure that, we've got a set of screw right here at the bottom, and then you'll see nice good solid mounting position there. All we have to do is determine where we want it to be positioned. We have two long zip ties which are going to be provided. We want those to go right up through the slots in the plug. We go around our hitch. It's going around when we started then we'll tighten them both down. Now they're good and secure. Let's just trim off our excess here in the zip ties. Now this is going to leave us with a little bit of excess four-pole wire, so what we'll do is just bring it over. Just kind of gather it up right there on top of the hitch and we'll use a zip tie. This one was not provided. The other two were, this one was not. We'll use that to just kind of keep that nice and bundled up there, out of the way. And that's going to do it for our Tow Ready 4-Flat Universal Mounting Bracket, part number 118149. .

Plastic mount bracket for 4-pole trailer connector zip ties around your trailer hitch or mounts to vehicle bumper. Provides a sturdy, fixed location to easily connect your trailer wiring.


I have purchased several trailer hitches and applicable wiring. All of the items purchased were as simple as it gets to install based upon your amazing website and tutorial videos.

I have recommended your company too many friends and look forward to doing business with you once again in the future.

Thank you


I used this to modify my Jetta Sportwagen hitch setup (purchased from to no longer need to open the rear hatch for wiring. Cut my 4-pin wiring harness, slipped it through the same grommet that the power lead ran through and spliced back together. It looks and functions great! Thanks for all your fantastic products!

Working perfectly
Mark - - 04/15/2022


This was boxed with the hitch I bought. Box was open when I received it and this was missing.


One of the big reasons I went with etrailer is the wealth of information they provided on various hitches that were made for my car. Great informational website and install videos! In addition, the online shopping experience was great as the site made recommendations about additional products related to the hitch I bought.

Delivery time was excellent, and all of my purchases arrived I damaged. 100% recommended!


This is the second one of these Mounting brackets I have purchased. The first over two years ago is working very well on my wife's car. This one I will install on my Travel Trailer for towing a small fishing boat or ATV. With the mounting bracket firmly holding the 4-flat wiring harness I can "one hand" the plug in with no difficulty. Dealing with is a breeze, actually I have already made another order since receiving this mounting bracket.

This Mounting bracket continues to preform wonderfully, no hanging wires, no dangling plug.
Carroll W - 07/04/2017


Installed in 4 -5 minutes while installing new Draw-Tite tow bar and Tow Ready One Connector wiring harness. Works really well, on vacation hooked and unhooked trailer twice a day, fast and positive, fits snugly. On '93 Honda Pilot had to mount pointing downward, I like that attitude for one hand plug and unplug.

Still pleased with this product one year later, keeps plug clean and dry.
CW - 03/27/2015


Didnt work well with round tube of hitch. Seemed like it was made for a square tube.

This item is designed to fit both square and round tubes.
-- Etrailer Expert Katrina B - 08/25/2022


This was a cost effective solution to secure the 4 pin connector to my hitch.


Doesn’t fit or attach to frame of hitch as the frame is hidden inside the bumper.


Great fit. Fairly straightforward install when visiting my son who has a lift. Would have been a whole lot harder without the lift.


I have ordered three different receiver hitches and accessories from etrailer and have never had any problems, very satisfied with his company and every aspect of the sale to delivery to the installation directions they help with. Highly recommended


I wanted some way to mount the electrical harness next to the hitch and this fit the bill. I wasn't able to mount it to the hitch so I screwed it to the lip of the bumper. I've been using it for a year now and have had no problems.

I use this all the time and have never had a problem with it. Considering it is exposed to the weather, it still looks brand new.
John N - 07/30/2020


Was a bit tricky to mount on my car because the hitch was tucked up under the bumper facia but I found a way to mount it and it is working well.


Perfect fit. Dyi..invite a friend


Always have a great experience buying for trailer. Fast shipping. Good quality products.


Didn't fit the 4 flat connector (which was too thick) provided with the electrical install kit. Not worth trying to return etc.

I recommend taking a look at part # 306-X6019
Eclipse Magnetic Mounting Bracket for 4-Way Flat Trailer Connectors
. It fits with most 4 flat connectors and uses a magnetic base to hold it to the hitch receiver.
-- Etrailer Expert Jenny N - 06/09/2022


The only reason I haven't given 5 stars is because I haven't tested the device yet. I really love the ease of installation! Very well done. The connectors fit perfectly. The cables had a good length (not too long, not too short). Vendor provided the grounding screw, all the necessary tie wraps, the double-sided tape, and good instructions. I recommend this product. I haven't been able to test it yet unfortunately. I purchased the Mounting bracket and the 4-Pole connector with wiring harness. See pictures.


I highly recommend etrailer for your towing needs. Ordered a Curt hitch and wiring kit for my 2005 RX 330. The price was right and the shipping was fast. Watched installation videos linked to the product. Hitch install was super easy and quick. The wiring kit install was time consuming for me, but the tutorial video was a great reference. Overall a smooth installation that went better than I expected


The 4 pin plug holder worked great. I did not have many mounting options so I fastened it to the hitch tube with the zip ties.


Not impressed at all with the mounting bracket. Both screws that hold the two pieces together actually stripped out and wouldn’t tighten. Had to use my own bigger screws in order to make it work.


I'm quite pleased with the 4-flat plug holder that I received from Etrailer. It holds the plug firmly and was easy to install. It has 4 plastic tabs that snap the 2pc. clam-shell holder together and two tiny screws that keep it together. It also has a allen-wrench set-screw to put tension on the plug to keep it firmly in place. There are zip-ties that can be used to go around the hitch cross-bar w/the option of installing horizontal or vertically depending on the space you are working with or configuration that works best for you. Though it is not set up to attach by screws (not advised to ever screw into cross bar) you could easily modify this w/ a couple of sheet metal screws or rivets. In my eyes, this product is a good value.




Used with the Curt T-connector wiring harness. The bracket would not stay shut, the screws were too far back. The dust cover on the harness was too large I believe. I gave it a couple rounds of electric tape. It did give a very clean install.


I received the product after I received the hitch I ordered a few days later. This is not a complaint, but an oddity. The hitch came from your location to an Illinois depot and then straight to my address, but this little Bracket went from your facility just outside of St. Louis, then to Kansas City, then to some burg in the middle of Ohio, then to Indianapolis, and finally to my house on the west side of IN. This caused me no issues as I waited until the weather was good to install the hitch therefore had the part before I needed it. I just though it was a " Long, Strange Trip." I like the product and my friends do too.


Easy to use and makes for a clean nice finish. Much better than having the 4-flat run out of your rear hatch or trunk. I say that because I used the factory rubber gaskets that ran wiring from under my car into my spare tire bay to run my 4-flat wiring to my hitch. Fixed up the gaskets with some gasket maker silicone looks amazing.

  • 4-Way Mounting Bracket Recommendation for Attaching to Round Tube Hitch
    How about the 4-Flat Universal Mounting Bracket # 118149? This bracket would zip-tie around the round cross tube of your hitch. Another option is to attach the bracket to the bottom of the bumper on your vehicle. For that you would want the part # 18144. I attached install videos for both kits for you to check out.

  • How Does 4-Way Install Into Bracket # 18144 So that It Doesnt Back Out
    If you check out the 1:15 mark of the install video I attached for the # 18144 that you referenced you can see how the 4-way has to be pushed into the bracket and then pushed up and down a few times to seat all the way so that you can push on it without it wanting to push out of the bracket.

  • Can a Trailer Wiring Harness 4-Way Be Stored Outside of a 1999 Jeep Cherokee
    You should not have to have the factory tow package to install trailer wiring harness # 118369 on your 1999 Jeep Cherokee. In order to stow the 4-Way on the outside of the Jeep you will have to look for a grommet that exists through the cargo area. You will likely have to remove panels and the spare tire to find a grommet. If there is no grommet you will have to drill a hole (careful not to drill through things on the other side!). Then you will need to seal up the hole after routing...

This bracket would zip-tie around the round cross tube of your Curt Hitch part # C13152 and would provide a bracket that would not require you to drill into anything on your 2014 Kia Sorento. If you do not have a 4-way the recommended one for your vehicle is the Curt Wiring Harness part # 56146KIT.

  • Is 4-Way Harness on 2006 Jeep Commander Compatible With Jet Ski Trailer Lights?
    The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118408 which fits your 2006 Jeep Commander will give you a 4-flat harness. A 4-way is a standard harness on trailers without brakes and it simply plugs into your Jeep's 4-way to power the trailer's lights. If you call the company you are renting the trailer from and ask if it has a 4-way they will be able to tell you. I do recommend using mounting bracket # 118149 to give your 4-flat a secure connection to your Jeep's...

  • Can Trailer Wiring Harness be Routed and Mounted Outside of a 2010 Honda Odyssey
    For trailer wiring harnesses that have the connector stored inside the vehicle you will just need to pull it out when needed and you can close the rear hatch on the wiring and the weather stripping will protect it. Stay away from the locking mechanism though. These harnesses were not meant to be routed permanently outside of your 2010 Honda Odyssey. If you wanted to do that any way you would need to remove the flooring getting down to the bare metal of the cargo area. Then you will need...

  • Best Way To Mount 4-Way Plug To Hitch
