Mounting bracket for 4-way flat connectors secures your trailer wiring up and out of the way. Includes required mounting hardware.


Solid enough, seems to only be able to slide through one way. I put it in the other way for a cleaner look but now it doesn't hold as well. I had to put a small bead of silicone to hold it in place.

Update a year later, working fine. Havent used it much but seems to be solid.


Works perfect, no more wires hanging down and possibly getting damaged by the pavement. Easy install and tight fitting. Didn't require additional hardware of any kind.

Jorge G.


Perfect, no issues and still tight to the hitch and bracket.


Mounting Bracket very flimsy, and not holding 4-Pole Flat connector.
I had to use tie straps to hold connector in the bracket.


This came shipped in several layers of plastic wrap along with the light kit, cap and small bracket. It was delivered with no damaga or scratches. It was fairly easy to install with the help of my son and a floor jack. we'll do the light kit installation another day. Everything lined up perfectly. We did remove the to plastic pins to make it easier to flex the plastic bumper. trim out of the way.


The mounting bracket worked perfect with both the Draw-Tite hitch, 76128, and Curt Harness, C56370, that I mounted on my 2024 Honda CR-V EX FWD.


Installation was easy and the video was helpful. However, I have found that the hole is slightly too small to keep the connector in and put the cap on. It works fine when connected to a trailer, but if I am not connected, I can't get the protective cap on.

I know that we have found that some harness brands do not work well with the bracket. Hopkins is one of those brands and I see that you had purchased a Hopkins wiring harness. It sounds like it is slipping out. If this is the case, I have heard that using electric tape to wrap about the connector to make it thicker helps.


A bit awkward to install after the hitch is already on your car. I couldn’t tighten the nuts as much as I would have liked because the screws were also spinning. I suggest installing this before attaching the hitch to your car, if possible. It’s does its job tough and holds the electrical socket in place.


This mounting bracket was the way to go when installing our Draw-Tite trailer hitch and T-One Wiring Harness on our 2020 Traverse. Bolted right on to the provided mounting plate on the hitch. Out of the way, yet easy access.



Actually this was for my Sister in law’s Traverse. Was easy to install and has been well hidden until recently when it was needed to install a wheel chair lift. Works great!


I bought my entire package (tow hitch, wire harness and connector bracket from etrailer and could not be any more satisfied. Found 2 etrailer videos on line and every installation detail was shown. My only contribution was using edger string vice airline tubing to pull the harness up through the fenders. Great etrailer video for hitch installation as well. I was easily able to obtain my desired result.


Easy to mount on the hitch and held the flat 4 connector very firmly.



Its been a year since I installed the mount and it is doing great.


NICE bracket easy install





Bought this hitch along with the wiring harness and 4-pole mounting bracket. My mechanic installed and it's been working great! Hauling well anytime needed!!


I ordered a hitch, wiring harness, and mounting bracket. Everything installed fairly easily and works great. All instructions where very clear.


The 4-pole flat connector of the Curt T-Connector harness snaps very securely into the bracket. An easy reach when attacking the trailer plug. A nice finished look to the whole hitch installation. Proper wiring is so important for trailer safety, don't skimp on such a simple way to protect your hookup.


This mounting bracket is just okay, but is certainly better than nothing. It doesn't hold the plug very well. I pushed the plug in far enough to get it seated correctly, but it still came back out when I plugged in the trailer. You have to push on both sides to get the connection properly. If you do that then it works fine. It is super simple which is good.


Exactly as described. Holds the 4 flat connector perfectly.


Extremely appreciative of the tech help I got from Phillip at etrailer
Knowledge was spot on with our vehicle and the products needed to install the hitch, wiring, and bracket.


The bracket assembly was packaged inside a larger box containing the trailer hitch that I ordered. The hitch box was damaged and the bracket was missing on the original delivery. I called etrailer customer service and they sent replacements immediately. I would strongly suggest packing the smaller items in a separate box to eliminate this issue. The bracket met all expectations and was thicker then expected. Customer Service, Ordering, delivery, and communication were outstanding from etrailer.

Rob L.


This bracket is working out great for the 4-way flat connector. Holds the connector in place as advertised.


Everything came as ordered. Everything was as described, and installation went off without a hitch …Pun intended


The 18144 bracket will not work with Hopkins wiring harnesses. The 4-pole connector is too thick to fit this bracket. This part was recommended in the installation video.

Yes, it is true that Hopkins harnesses will not fit correctly into this bracket. For Hopkin harnesses I recommend part # BK4F. I also checked to make sure the bracket was not recommended in our videos for the Hopkin harnesses for a 2011 Dodge Grand Caravan.


Bolted easily to a "no drill" mounting bracket. The plug took a bit of coaxing to fit into the bracket but once in, it is very secure.


The installation was very simple. I'm able to store the harness in a protective manner when not in use. All positive reults.


I have purchased several items from etrailer in the past. Most recently, for my 2018 Jeep Wrangler. I installed the hitch, mounting bracket and wiring. All worked perfectly and the instructional videos and on line support are outstanding. I only think of etrailer when looking for trailer equipment. Thank you.


This mounting bracket is a really good option to get on your trailer hitch to keep the flat 4 connector in 1 place instead of flopping around. Recommended.



working as designed.


I was very impressed, when I received the trailer hitch and opened the box, all 3 items I had ordered for the hitch were in the box. I was able to finish the installation that day!!

  • Mounting Location Recommendation for a Mounting Bracket # 18144 on a Honda Pilot
    We do not recommend you drill into the hitch to install the Mounting Bracket 4-Pole Flat # 18144. Typically you will install this bracket onto the bumper or rear fascia. Like you said, drilling into the hitch could potentially affect the structural integrity of the hitch. If you wanted to drill a pilot hole to use a starter hole to install the # 18144 you certainly could.

  • How Does the 4-Way Mounting Bracket Keep the Connector from Falling Out
    The 4-Way connector just press fits into the bracket and keeps the connector secure. There are small ribs on the connector that help hold it in the bracket. The cap also goes around the connector to help secure the 4-way just in case it gets knocked out of the bracket.

  • Troubleshooting Parking Lights Not Working With 4-Way
    Based on what you are describing this is a ground connection issue. Typically when one function is not working correctly you have a loose/bad ground. Make sure your ground connection is secure on a clean, bare-metal surface. If this does not solve the problem then the other thing I would check is the connections from your installation. I'm not sure what wiring harness you have, but you could unplug the connections and plug them back in to make sure they are seated securely. I have attached...

  • Will a Sierra Brand 4-Way Flat Trailer Connector Fit Tow Ready Mounting Bracket
    Mounting bracket # 18144 fits most 4-Way flat trailer connectors. We don't have Sierra brand connectors so I can't test it. We do know that it will not work with Hopkins, Wesbar, TAP or Plug-N-Tow brand connectors. The worst case scenario would be that the connector is too large and you would have to file out the opening on the bracket a little.

  • Recommendation On Where To Attach Hitch Wiring Bracket To 2017 Range Rover Sport
    I am not sure which 4-Pole bracket you have but most are similar in design and installation. The bracket should be installed in a sturdy location on the lower portion of the back bumper near or on the hitch. If on the hitch, do not attach by drilling but use something like a hose clamp because drilling will void most hitch warranties. The Tow Ready Mounting Bracket, Item # 18144, is commonly used and we have an installation video that I am sending you. If you have a different bracket,...

  • Harness Bracket Needed for 4-Way Trailer Connector
    I recommend taking a look at your wiring harness to determine what brand of harness is installed on your vehicle. If the wiring harness on your vehicle is manufactured by Draw-Tite, Hidden Hitch, Reese, Tow Ready or Valley, the Tow Ready Mounting Bracket, # 18144, will work for you. If your wiring harness was manufactured by a different company, please send me an email with that information and I will be happy to see if we have a bracket that will work for you.

  • How Does 4-Pole Mounting Bracket # 18144 Normally Attach to Rear Bumper of Vehicle
    To install the 4-way bracket part # 18144 that you referenced you'd need to use the included hardware to attach it to the bottom of the rear bumper. We don't have any pictures though that show it installed on a Commander like yours though. I did attach an install video that uses this bracket as well as an install picture too.

  • Screw and Hole Sizes for Mounting Bracket 4-Pole Flat # 18144
    For the Mounting Bracket 4-Pole Flat # 18144 the silver self-tapping screws are 0.15 inches in diameter at the threads. Since they are self-tapping a hole is not required but if you wanted to first drill a pilot hole I would go with a 1/16 inch. The black screws are 3/16 and the nuts that go with them are the same. The holes in the bracket have a diameter of 0.2 inches. All measurements were taken using digital calipers.

  • Using 4-Pole Trailer Adapter Part # 118384 for Tailgate Light Bar on 2008 Silverado
    You are absolutely correct. The 4-Pole Trailer Adapter part # 118384 would plug inline to the connector for your existing 7-way trailer connector. If you need a mounting bracket for the 4-Pole, we offer part # 18144. To see the installation instructions for the Adapter, click on the link below.

  • Trailer Wiring Harness Install 2000 Isuzu Rodeo
    We have not had the opportunity to install the Tow Ready T-1 Vehicle Wiring Harness on a 2000 Isuzu Rodeo, so we do not have a video available. I reviewed the installation instructions (see link), and it appears that the installation is not too terribly involved. You would start by removing the tail light assemblies, which is typically accomplished by opening the rear hatch and removing the fasteners that pass through the door jamb into the tail light assemblies. You would then unclip...

  • Adding a 4-Pole connector at the Rear of a 2010 Ford F-150
    You could add an extra 4-Pole connector at the rear of your 2010 ford F-150 by using a circuit tester and probing the vehicle trailer connector wiring to find the correct circuits to splice into. We have a 4-Pole Hardwire Kit Including Circuit Tester, item # 18252, that has the circuit tester and four wire taps, which is all you would need to complete the installation. You may also want to use a mounting bracket to secure the connector when not in use. The Mounting Bracket 4-Pole Flat,...

  • Will the 4-Pole Mounting Bracket Work with the Quadratec Wiring Harness 92015 8001
    The 4-Pole Mounting Bracket part # 18144 should allow you to secure the trailer connector on your Quadratec Plug-n-Play Tow Hitch Wiring Harness 92015 8001. However, we don't carry Quadratec wiring harnesses so I can't say we have tested them together. It looks like you might have to put a bit more pressure on the plug to insert it into the mounting bracket or trim some of the rubber but you should be able to make it work. If you don't have a tab on your trailer hitch for the bracket...

  • Comparing Current Output of Tow Ready and Curt Wiring Harnesses for 2013 Dodge Journey with LEDs
    A vehicle that uses LED-type lighting for its own light functions will typically use smaller gauge wiring than a vehicle that was designed with standard incandescent lights which draw roughly 10 times as much power. This efficiency with LEDs makes the vehicle able to use less copper, which means both lower cost and lower weight. Not a bad thing. That lighter-gauge wiring also means that the trailer wiring harness you use will have to be a powered type, which draws the actual power for...

  • Availability Of Bracket For Permanently Mounting A Trailer Plug On Bumper
    We generally use a bracket like the Mounting Bracket # 18144 to permanently mount a 4-flat plug. You can use a few self-tapping screws to mount in on the bumper, or really wherever you want. We usually will attach the bracket to the cross-tube of the trailer hitch.

  • Recommended Trailer Wiring Harness For A 2023 Hyundai Santa Fe
    I recommend the T-One Vehicle Wiring Harness # 118784 for your 2023 Hyundai Santa Fe. I like this harness over the others we offer because it has a more reliable powered converter box and you will get a longer run time and more usage out of it than the other harnesses. This T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area. Once the installation is complete, the 4-way flat connector will be stowed...

  • Will Trailer Wiring Ruin the Paint Finish on a Chrysler 300C When Routed Out of the Trunk for Towing
    The wiring being stored in the trunk is pretty standard especially on passenger cars. When the wiring is closed in the trunk the rubber seals protect the wiring and the vehicle finish. You will not want to allow a large amount of extra wire to be left hanging out of the trunk or the wind could cause the wiring to rub on the vehicles finish. Find a happy medium and you should not have any problems. Keep the wires clean so that when you are towing, grime on the wires does not have a chance...
