Video Transcript for Brophy Mounting Bracket for 4-Pole Flat Trailer Connector Review

Today, you're going to be taking a look at the Brophy mounting bracket for four-pole flat trailer connectors. That's going to be part number BK4F.So here's what our four-pole bracket's going to look like once we have it installed. It's going to allow us to have our four-pole wiring right by our hitch. That way whenever we get ready to tow, we can plug right up. This is going to be a lot better solution to secure our wire rather than just hanging it on our hitch or securing it to our safety chain connection point because we don't have to worry about our wires hanging down and possibly getting damaged.Our bracket is going to work with most four-pole standards plugs, and even if we remove the dust cap, you can see it's not going to fall back in even if we have to really push to plug in our trailer. Installing it is going to be as simple as putting two bolts in and running your four-pole connection through the bracket.

Let's show you how to do that now.Our four-pole bracket is going to have two holes on it, so we can either mount it to our hitch or another bracket so we can put our wiring in place. Keep in mind that our bracket's not going to come with any hardware, but if you are using a short or long bracket, there will be hardware with that kit. So I'm going to drop down my hardware from on top of the bracket. I'll line up the hole in my four-pole bracket, and I'll do that for the other hole as well. Then I'll come back and tighten up all the hardware.Now, you just want to take the dust cap off your four-pole, and coming from the back side, we'll push it through.

You just want to make sure that you push it in far enough that the tabs on there are going to catch. This will prevent it from going back in. I'm just going to have to work it back and forth a little bit. Then we can tie up any of the excess wires behind the hitch, and we can even put a little bit of electrical tape to hide the color on the back of our car.That'll finish up your look at the Brophy mounting bracket for four-pole flat trailer connectors, part number BK4F.

Brophy Mounting Bracket for 4-Pole Flat Trailer Connector - BK4F

Average Customer Rating:  4.6 out of 5 stars   (413 Customer Reviews)

Bracket for 4-way flat trailer connector mounts to your trailer hitch or vehicle bumper and provides a sturdy, fixed location to easily connect your trailer wiring.

by:

Just what I wanted. This bracket is a perfect fit for my trailer hitch receiver. Bracket installs very easily and keeps the 4-pin connector looking nice and neat without having it hang below the bracket or bumper.



by:

All 3 items arrived together and on schedule. The only reason I do not give the purchase 5 stars is because the wiring harness had to be modified to work with my car. If I didn’t go to a trailer repair company, the wiring may still not be on the car.



by:

No instructions!! I have no idea how the flat connector is supposed to mount this thing

You can mount this to your bumper with self tapping screws or you can mount it to part # 18140 which is an additional bracket that uses a metal zip tie to connect to the hitch. I have linked a video below that explains it in more detail.



by:

This is a great mounting solution for the 4-pin flat trailer connector. Works as advertised.



by:

Delivery was fast and on time as promised! Installation videos and instructions were spot on. Would highly recommend!



by:

Easy to install and works great to keep the wiring harness from dragging.



by:

Mounted fine to bumper, but does not hold harness at all.

That is kind of a bummer. Sometimes the bracket can be just a little too big and harness a little too small enough to make it not work. What I recommend is to use electrical tape to thicken up the four flat connector so that it stays in place.



by:

Works like a charm. Highly recommend etrailer.com A+++++++



by:

Easy to install and etrailer was very helpful finding the right parts.



by:

Easy to install as depicted in video.



by:

It is fine but did come with any mounting hardware.



by:

Couldn’t have been much easier. Remove the plastic cover under the left rear of the vehicle (3 push pins and 2 14mm plastic nuts), remove the cap on the factory harness, plug in the new harness and secure the wires as you see fit. There’s no instructions for wire storage or how to route them, but it’s very simple - use common sense - plenty of YouTubes.



by:

Seemed cheap (Thin metal) but works well with the harness kit. I bought this because NOBODY makes a aftermarket flange mount flat plug only trailer plug in.

little oxidation on the pins. a little sanding and dielectric grease and alls well.



by:

Simple but effective means to hold connector. I taped everything for more secure and professional looking mounting.

Just fine! Not a complicated device!



by:

Have been doing business with these guys for a while now, they are the best. Good products and excellent customer service. Every time I have a product question, whoever I am talking to knows their products well.



by:

Great bracket quality for the price.



by:

Like that all parts are exactly as called for on the vehicle



by:

Instalation was pretty quick and easy, the completed installation worked great on my new trailer.



by:

Very good customer relations and fast service.

Thank you Carl Cole



by:

Perfect, sturdy and good fit.

Installed on Curt No-Drill Bracket for 6-Way or 7-Way Round Trailer Connector Mounting Bracket - Long on to Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" worked great just what I needed!!



by:

Bracket is well made however it was very difficult to get my 4 prong plug in the bracket properly. Actually had to open the slot abit just to get started. With all that being said the finish product looks great. Not sure this bracket if this bracket was supposed to be a good fit



by:

Good quality

Works well.

  • Will the Curt Powered Tail Light Converter # C59236 Fit a 2022 BMW X3?
    Yes, the Curt Powered Tail Light Converter # C59236 will fit on your 2022 BMW X3. If you are worried about splicing into the wires we do have the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT which uses sensors placed over the tail light wiring. These sensors detect when power is going through the wiring to activate the 4-way wiring. You will want a Mounting Bracket # BK4F if you plan on mounting the 4-way near your receiver rather than running it through the rear hatch when needed.

  • How to Add Additional 4-Way Connection to a 2022 Ford F-350 Super Duty
    I've got a quick and easy solution for you with the Curt T-Connector Vehicle Wiring Harness # C55384. This tees in behind your current 4-Way/7-Way using the US CAR connection and gives you an additional 4-Way that you'll be able to use the same time your 7-Way is being used. I recommend picking up the Brophy Mounting Bracket # BK4F and N-Drill Mounting Bracket # 18136 so the additional 4-Way can be held in a place that has easy access.

    Yes, the Curt T-Connector Vehicle Wiring Harness # C56375 will fit your 2020 Chevrolet Equinox with the factory tow package, or if it has the plug at the back of the car. We can only base what is confirmed to fit either by what we have installed ourselves or the information that the manufacturer gives us. Fortunately I have installed tons of wiring kits on the Chevy Equinox and I can confidently let you know that so long as you have the plug behind the bumper it will work. It's extremely...

  • Wiring Recommendation for a 2023 Kia Sorento Without a Tow Package
    The Curt Trailer Hitch Receiver # C34ER is a great choice for your 2023 Kia Sorento and I recommend picking up the Tekonsha 4-Way wiring to add to your vehicle: - T-One Vehicle Wiring Harness # TK26FR This wiring simply tees into your factory plugs behind the tail lights on your vehicle and then pulls power from the included power lead. I also recommend securing the 4-Way next to your hitch receiver by using the brackets # C57202 and # BK4F.

    You have the Class III Draw-Tite Max-Frame Trailer Hitch Receiver, 76192 on your 2018 Volkswagen Tiguan, this has an integrated mounting point for a 4-pole flat trailer connector. I suggest the Brophy bracket, # BK4F. Simply install the T-One Vehicle Wiring Harness, # 118811 per included instructions and then put the 4-way flat plug through an existing opening in the floor pan of your Tiguan. There will be multiple holes in the pan with grommets, plugs. Pull one of these and feed the...

This bracket will attach to the pre drilled tab on the Draw-Tite hitch. None of the 4-way wiring harnesses for any vehicle include this bracket.

  • How to Carry a Heavy Kayak with the 2022 Chrysler Pacifica
    To transport a kayak with your 2022 Chrysler Pacifica we'll need to get you a trailer hitch so you can tow a roof rack on wheels since there currently (as of May 2023) aren't any roof rack options for your vehicle aside from what it comes from the factory with, and even that isn't compatible with the Hullavator. For the trailer hitch I recommend the Curt Trailer Hitch Receiver # C65CR because it has a 2" receiver and hidden crosstube. Then for wiring you need the T-One # TK96FR along with...

  • Correct Curt Wiring Harness for 2023 Ford Bronco with LED or Halogen Tail Lights
    It does matter if your 2023 Ford Bronco has LED lights or not, but once you figure that out it's just a simple matter of getting either of these harnesses: - With LEDs # C42WR - Without LEDs # C87BR Both options plug in behind your tail lights and then draw power from the vehicle battery via the included wiring lead. I also recommend picking up the mounting brackets # C57202 and # BK4F so you can secure the 4-Way connector next to your hitch receiver for easy access.

  • Hardware Needed to Install the Brophy BK4F on a 2019 Nissan Frontier
    To install the Brophy # BK4F you can simply use self tapping screws like the # FA1131822 to secure this bracket to your hitch. You won't be able to use bolts since this is connected directly to the tube of the hitch on your 2019 Nissan Frontier. You could also use the # 18140 to allow for a no drill/screw application.

  • Best Trailer Hitch and Wiring for a 2023 Toyota Highlander XLE
    The best hitch for your 2023 Toyota Highlander XLE is the etrailer Trailer Hitch Receiver # e75ZR because it has the hidden crosstube and the matte black finish. I've had two of our hitches installed on my own vehicles and I really like the look of the matte black finish, but it also does a better job at hiding any nicks or dings that can happen from road debris like rocks. Then for wiring you just need to know if your Highlander has the tow package or not. If you aren't sure you can...

It also has a hidden cross tube so all you will see is the 2" receiver opening and the chain hook loops. The T-One Vehicle Wiring Harness # 118255 will allow you to plug into the factory harness so you have a functioning 4-way to connect on small trailers. It can also be used for Auxiliary Lights # C53201 if you have...

  • Does the Curt C13284 Hitch Fit a 2023 Mazda CX-9?
    According to Curt the Item # C13284 hitch you were looking at stopped fitting the CX-9's after the 2022 model year. The correct hitch for your 2023 Mazda CX-9 is the Draw-Tite item # 76020. This hitch is custom fit and bolts to your Mazda with included hardware. This is a class III hitch with a 2" receiver. It has a 4,500 lbs towing capacity and a 675 lbs maximum tongue weight. This hitch can be used with weight distribution systems but that will not increase its capacity. I have linked...

  • Best Way To Attach Trailer Plug Bracket To A Trailer Hitch Without A Pre Welded Bracket
    As far as the mounting bracket, you can absolutely screw it directly to the hitch if you want. We do this frequently in our own installs and it will not compromise the strength of the hitch in any way. Now putting a few holes in the hitch does open up the potential for rust, since we are compromising the powder coating, but the risk is small. You could use the bracket # BK4F for a 4-flat or use the # C67UR for a 7 way, and a self tapping screw like # 101131802. If you do not want to drill...

I verified with Draw-Tite that this hitch will fit the 2023 models. For a custom fit wiring harness you will want the Tekonsha T-One Vehicle Wiring Harness for Factory Tow Package item # 118278.

    The Curt Trailer Hitch item # C23WR and the Draw-Tite Hitch item # DT48GR are almost identical and are both confirmed to fit the 2023 Hyundai Santa Cruz. The main differences between the two hitches are that the Curt is made in the USA and the Draw-Tite has a built in tab to mount a 4-way or 7-way wiring bracket.

  • Recommended Plug-In Trailer Wiring Harness for a 2023 Toyota Venza
    I recommend installing the Curt T-Connector # C57ER on your 2023 Toyota Venza because it tees in behind the tail lights as opposed to splicing into the OEM wiring like universal options do. The only spliced connection you have to make with this wiring is running the 12V power lead up to your vehicle battery so the trailer lights are powered that way instead of through your OEM circuits. You'll also want to pick up the mounting brackets # C57202 and # BK4F so you can keep the 4-Way near...

You'll also need the 4-way mounting bracket # BK4F and # 18136 to secure the 4-way to your hitch. If you don't already have a trailer hitch installed then you'll want to pick up the etrailer # e38KR as well.
