Video Transcript for Review of Curt 4-Pole Flat Trailer Wiring Mounting Bracket - C42CR

Michael: Hi there. I'm Michael with Today, we're going to take a quick look at the Curt mounting bracket for your four-pole flat trailer connectors. This mounting bracket is going to attach to your trailer hitch to provide a mounting point for your four-way flat trailer connector. It's very easy to get installed. Just slide your four-pole trailer connector through, and it's going to provide that constant consistent mounting point for you to easily hook up your trailer wiring to when you're ready to tow.

You'll always know where it's at and it's going to be there ready for you. This does install directly onto your hitch or bumper or vehicle frame.Depending on how you want to get it mounted, there's also the option to do a no-drill mounting bracket. You can use the long version, there, or the short version. That's just going to wrap around your trailer hitch or vehicle frame, so that you don't have permanent drilled holes in any of those components. So, depending on how far out you need it to stick out from your frame to clear your bumper to have easy access will determine which one of those that you would need.

You really don't have to use either of those. If you're okay with drilling into your trailer hitch or bumper, they do have the two holes right up there on top. This is right about two and a quarter of an inch wide by just shy of an inch and three quarters.And then the top bracket there, it's about an inch and a quarter, as you can see. So, make sure that that's going to work for your application. It should fit just about any and be very easy to get installed.

It is constructed of a durable steel. So, it's going to be very long lasting, very rugged for you. It also has a black powder coat finish on it. So, it's going to resist rust and corrosion. So, it should last you a nice long time.

Like I said, give you that nice consistent mounting point for your trailer, so it's one less thing you have to think about. Just easily hook up and you're ready to go. So, that's going to complete our look for today. Again, I'm Michael with Thanks for watching.

Curt Mounting Bracket for 4-Pole Flat Trailer Connector - C42CR

Average Customer Rating:  4.7 out of 5 stars   (134 Customer Reviews)

Attach your trailer connector mounting bracket to your vehicle. Simply bolt this sturdy steel bracket to your trailer hitch, bumper, or vehicle's frame. Use with a no-drill mount (18136 or 18140) for an even easier installation.


Easy and simple. Only gave 4 stars because item did not come with mounting bolts. Easy fix with bolts I had on hand. No drilling required because it was compatible with the Draw Tite Class III (76034) I also purchased from etrailer.

No issues since the day I mounted it.
Javi - 03/10/2022


Simple, but works perfect. Drilled and tapped the hitch cross tube to mount the plug mounting bracket.


Really like the design. 4way plug bracket attached to bottom of bumper.
Used 2 small bolts with locking nuts.
The bumper on the sportage is about 1/4inch thick,so plenty of support.
Plug just snaps in,no more hanging wire
Looks nice and organized


Used in conjunction with draw tite hitch mount and tekonsha harness, fit mount tab on hitch and plug of harness perfectly. Nicer than zip tying. Just needed a couple screws and lock nuts from the hardware store, has held up fine over the last year.


Perfect fit to hold trailer lighting pl ug.

Excellent product. Continues to work as advertised.
Dennis - 06/02/2022


I had to modify it slightly to fit the another manufactures plug in the slot. Worked as expected.


Fits my pigtail perfectly. Just make sure your setup is perfectly to your liking before inserting the pigtail. Once it goes in it does not come back out. I tried to take it apart recently to add a dust cover and it caused significant damage the pigtail. I was able to finally get it and it popped right back in, but looking back on it I wish I had set it up that way from the start.


This is my go to four flat connector bracket. Holds the connector firmly in place.


no problem installing it


This trailer lite harness was easy to install on my 2020 Palisade. Hyundai has it easy to remove the wiring cover which helped with an easy installation.


I don't know didn't receive the Bracket

Thank you for your review about your experience with etrailer. I saw the second box containing the bracket was delivered. I was wondering if you had any feedback about the product for other shoppers? We look forward to hearing from you.

Needed a secure mount for 4-way connector. Etrailer had the part and delivered promptly. Curt provides high quality products and this mount fits the bill perfectly.


Very clean looking install. Uhaul actually complimented the install and product


First time I've purchase an e-trailer branded hitch (I have purchased Curtis and Draw-Tite from e-trailer in the past). Looks really well made. All of the items were as expected, first quality, well packed and as advertised. Will add some photos once I have the hitch and wiring installed.


I cannot review because I didn't receive this product it was not included in the shipment

It is never fun to receive an order with a missing part. I will have our customer service department reach out to you.

Convenient feature for sure


Awesome But Could Of Included Some Self Tapping Screws...


Quality product and fits the wiring harness perfectly!


A little smaller than I thought, but appears to fit/work great. Four pin connector fits tight. Will install this weekend..


It is ok, it does it job but it could hold the plug a little tighter. I put some silicone on to hold it tight.


I ordered a new trailer hitch, wiring, and brackets and all came very quickly. The addition of videos on the website helped with the install that I was able to do myself. I would highly recommend ordering from etrailer as the service was great and the products received were exactly what I needed.


Great kit, works nicely.


Easy install.


Easy to install, but comes with no bolts to do so. I had some stainless nuts and bolts on the shelf and all is well. Holds the 4 wire connector very securely, better than I expected.


Exactly as advertised.
