Mounting Bracket 4-Pole Flat - 18144

Average Customer Rating:  4.8 out of 5 stars   (3781 Customer Reviews)

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


Works great, I bought this thinking it would attach to the hitch I purchased but the hitch didn't have a spot to screw this into. I made it work by slipping straps through it and tightening around hitch. Worked perfectly

You can also use the mounting brackets that strap to the hitch along with this bracket. They are part # 18140
No-Drill Mount for Electrical Mounting Bracket - Short
that is shorter and part # C57202
Curt No-Drill Bracket for 6-Way or 7-Way Round Trailer Connector Mounting Bracket - Long
which is longer.
-- Etrailer Expert Jenny N - 04/28/2022


The mounting bracket 4-pole flat gets the job done. It's a little smaller than what I had pictured in my mind, but that's probably a good thing. It can be a little tough getting the harness plug set into position, but once in place I think it will do a good job of keeping it there. It makes for a nice clean look for your wiring harness. Definitely worth the cost!


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.


item was exactly as described. Will allow me to properly mount and protect my trailer light connection. Came with everything needed to mount to tow bar (many brackets do not, be careful ordering elsewhere)

After a year, the bracket is still keeping my connector firmly in place and my wires up and out of the way. Was easy to install and well worth the price.
David - 05/18/2022


It works not isn’t great. The plug isn’t very secure when pushed into the opening and I had issues with the self taping screws breaking. Maybe rhat was my fault? Got it installed though and suits my purpose.


Easy installation


I purchased this product along with a trailer hitch receiver and wiring harness for my car everything came in one package before they were expected as usual with etrailer whom i have recommended to people I know, I had everything installed and I am very happy with everything, and will purchase from again and have referred them to my friends


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.


I installed this on my 2018 Wrangler and it was perfect. Very simple install. Videos were very helpful. Took about 3 hours by myself. It may have taken a little longer because I ran the battery wire inside the frame for protection. Seems to be very good quality and I would recommend this harness to anyone needing to add a trailer light plug to their vehicle. Thanks etrailer.


I have used this mount bracket #18144 on three different vehicles.Wouldn’t do a plug in without it so many ways to mount It. Great product. 2016 Ford Explorer


The install video said it would fit behind the cover of my 2021 Jeep GCL . But if you put the 4 point connector in the mount bracket. The hitch cover won’t close or fit properly. The option is to no put the 4 pin connector in the bracket. Then what’s the purpose?

This may stick out too far on the 2021 Jeep Grand Cherokee factory hitch to use the cover. Most customers just store the wiring in the cargo area, pull it out and close the hatch on it when in use. As long as your weather stripping is in good shape it wont damage the wiring.
-- Etrailer Expert Heather A - 02/24/2022


This product fit the Draw-Tite hitch perfectly and holds the wiring harness tightly. Just right for the job. Thanks.


Purchased with a Draw-Tite hitch that has the bracket welded to the cross member. No sweat to install onto hitch.

Remember to mount the bracket to the hitch before installing hitch. Also, the vertical tab with the slot must face the rear of the truck to accept the plug from the wiring harness.

Product has worked fine this this past year.
Doug F - 10/09/2018


This will be a great harness mount bracket. My hitch is constructed of round tubing. I haven't mounted this bracket at this time.


Super easy to install. Super easy. They have a insulation video on the webpage that shows step-by-step how to do it. I didn’t even need to lift my car off the ground to put it on. Just tested it out this weekend on a camp out where I attached a cargo carrier and bike rack in one. It put a lot of torque on the hitch especially when you hit dips on the freeway going 70. The hitch didn’t budge. Now I just need to get heavy duty shocks.


All is good. I would like to buy an affordable electric bike bike rack.

Glad to hear this part is working well for you. As far as electric bike racks go, part # S64678
Swagman Current Bike Rack for 2 Electric Bikes - 1-1/4" and 2" Hitches - Frame Mount
may be a good place to start. It is rated to be used on the back of motor homes as well. It can hold two sixty pound e bikes with tires up to five inches wide. This rack works on one and one quarter inch to two inch hitches. At this time it is the most economical option, but sometimes prices can fluctuate so just be aware of that.
-- Etrailer Expert Brooke M - 05/30/2022


Great product easy to install. Quick delivery. etrailer installation videos are very helpful

Working as expected, no issues
Thomas - 04/09/2022


This is a great place to order from. You can actually talk to a person.
I ordered a hitch for my 2007 Ford escape. It fit perfectly took about an hour to install including wiring harness.


Attached to vehicle's trailer hitch assembly where previous bracket was located. Worked well and the T-One Vehicle Wiring Harness 4-Pole Flat Trailer Connector fit securely. The Connector's attached cover even worked - it comes around the side and fits securely over the 4-pole flat connector terminal end.

In the year since I purchased and installed this item I have had absolutely no issues with it. It has continued to perform as designed and as expected.
Johnny A - 11/28/2021


It has been a year since I installed the receiver and wiring harness on my 2015 GMC Acadia. I am very pleased. They have gotten used a lot. I do lawn care and use it to pull my trailer. I drove my trailer with my Harley Davidson on it all the way to Tennessee. I would recommend the little wiring harness support bracket that I purchased on every order. It is great and makes the 4 flat plug look tidy bu not dangling down or being tied up. No issues at all. Thank you E-Trailer for inquiring about it after it has been installed for a year.


I am very pleased with the customer service that I received from Montrell. He went over my order with me. We talked about what I was using the for. All supplies came to me in a timely manner. I watched the installation video. It made installation very easy. Thanks again for great service.


Adding a trailer hitch and wiring to 2015 Lexus. etrailer had everything I needed to get this done. I put on the hitch and the bracket for the four pole connector to the trailer. After looking at the the wiring instructions for the Lexus, I decided to hire that out. Prices were really good and the quality is rock solid.


I don't know why hitch manufacturers don't all just get it and add this bracket, it would make life so much easier! Thanks to this little gem my wife's car doesn't have a dangling hitch connector.


Order arrived timely and was packaged well. Price point was reasonable for the items. All parts and fasteners were included and of good quality. Instructions were included that made the installation simple. I also found a [online] video that showed the installation on my exact vehicle (Jeep Grand Cherokee) which made the installation a perfect match. Parts installed exactly as shown in the [online] video.


It fits the tab that's welded on to the hitch I ordered so that is a good thing. It looks to be well made and comes with the attaching hardware.

Ask the Experts about this Tow Ready Accessories and Parts

  • 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.

  • 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.

  • Dimensions of the Mounting Bracket 4-Pole Flat # 18144
    I pulled a Tow Ready 4-Way Mounting Bracket part # 18144 from our warehouse to measure it and found that it measures 1-3/4 inches in height, 2-1/4 inches in width, and 1-1/4 inches in depth.

  • 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.

  • 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.

  • 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.

  • 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,...

  • 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...

  • 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 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...

  • Trailer Wiring Harness for 2013 Hyundai Santa Fe
    The fact that you have located the connectors under the vehicle on the drivers side frame rail indicates that your Santa Fe is equipped with the factory tow package. The Tow Ready # 118269 would indeed be the correct wiring harness. I have confirmed this with Tow Ready. Using a mounting bracket like part # 18144 is recommended. The installation is very simple and straightforward, as shown in the installation instructions I have linked you to.

  • Will Hopkins Wiring Harness 42615 Work on a 2000 Jeep Wrangler Towing a Trailer with 4-Way Wiring
    Yes, the Hopkins plug-in wiring harness # 42615 would work well on your 2000 Jeep Wrangler, and give you the required 4-Way plug to connect to your trailer. This wiring harness is connected underneath the vehicle, on the passenger's side, behind the rear tire mud flap. I would recommend a mounting bracket like part # 18144 to store the plug when not in use. You can view some additional information on wiring for towing at the links below.

I attached installation instructions for this product below for you to check out. The 4-pole trailer connector will be stowed under the vehicle close to the trailer hitch. A mounting bracket is recommended. For that I would recommend a Mounting Bracket 4-Pole Flat, part # 18144.

The wiring harness part # 118424 is designed to store on the inside of your 2012 Acura MDX and then when you need it you would be able to open the rear door and pull the harness out so that you can attach it to your trailer.
