Video Transcript for Draw-Tite Accessories and Parts 18156 Review

Today we're going to be reviewing part number 18156. This is the Draw-Tite 6- and 7-way Trailer Connector Mounting Box. This is designed for 6- and 7-way connectors. It's going to be designed for use with all hitches with 2- inch square cross tubes. You can see here that this design is going to fit that 2-1/2 inch square cross tube perfectly. It's going to sit right in there alongside your hitch. It's going to come with the metal mounting strap to mount this to your hitch.

Very simple to operate, just run it through the appropriate slots, run it around your hitch back into itself and tighten up that set screw on top. It's going to feature a nice compact and professional appearance. It's made from a nice hard plastic construction which makes it very durable, and it's also made from corrosion-resistant materials. Very simple installation, whether you're installing this on new or pre-wired vehicles. It's going to include the screws to mount the connector to the box. I have a connector here today.

This is going to be sold separately; you can see there how it fits in there. It gives it a nice appearance. This is going to be the connection point for the wiring so it allows plenty of room. It's also got a nice little cutout here to feed your wiring out through that slot. Some measurements to go over real quick, the overall length, measuring from edge to edge of the outermost points, that's going to give us a measurement of 5-1/4 of an inch. The overall width, that's going to give us a measurement of about 4 inches from outer edge to outer edge, and then the cutout here, again this is going to measure 2-1/2 inches.

Then the diameter of the hole that we have right here, that's going to be about 2-1/8th of an inch. It's already got pre-drilled mounting slots in there, and again it comes with the mounting screws. That way you can mount the connector to the box. That's going to do it for our review of part number 18156. This is the 6- and 7-way trailer connector mounting box from Draw-Tite Accessories and Parts. .

I attached this to the hitch I bought from My hitch is up tight under the bumper fascia and I installed this item on the square cross bar on the driver side. This arrangement makes both the hitch and the RV receptacle out of sight when looking at the rear of my Town & Country mini-van. 323514

I received an email saying one of the items I ordered, was not in stock, I was given a choice to take an alternative item, which would have worked just fine, I chose to wait for the exact item. To my surprise it came to the house two days after being told I would have to wait. My whole order took just short of a week to get, even having to wait for a part not presently in stock. All the stuff I ordered was in perfect condition, and properly packed. Very satisfied with your service and price. Thanks, Doug P. 340223

I purchased this to restore the 7-way recreational trailer connector. The previous owner had cut off the factory connector box and connector. This box mounts directly to the hitch's support tube and is slightly angled outwards to provide suburb clearance. Works great! 271810

This product was recomended as an additional part for a Honda Pilot wiring kit but it was not useful at all. It did not even fit in the space behind the plug because the spare tire is in the way. This should be taken off the recommended accessory list for the trailer wiring kit. 76543


This product is meant to be attached on the front side of aftermarket hitches. It should not be used on the back of the hitch. If it is an OEM hitch, there may not even be a way to properly attach it since many OEM hitches are integrated as the bumper structure.

This is a very good replacement option for a seven way connector on a low hanging trailer hitch. Installed on a Lexus rx300 that had the seven way torn off because of the low mounting. This brought the connector up even with the hitch, works well and easily installed. 170438

This mounting box was a bit more 'plastic-y' than I was expecting. And the hose-clamp was initially difficult to tighten up... but once I got it installed and tightened down, it was more sturdy than I was initially expecting. For the price, it seems like a good value. 9412

This trailer connecting box mount fits well and holds securely My socket cover now sits under the bumper out of the elements. The previous mount I had held the connector at an angle, water built up and rusted the bottom 2 connectors. This one sits nice and level. 65915

by: JimDogs09/13/2017

This is a great mounting unit for the 7-pin trailer connector! The side-angle mount keeps your plug under the bumper and is tucked away so nothing hits it, potentially disconnecting trailer electric from the tow vehicle. I like it so much I now have 2 of them! 431900

Used this bracket to replace one that mounted below the crossbar of the hitch, which made it too low. This will allow the plug in to be as high as the crossbar and won't drag in driveways, entrances, etc. Works great, mounts easy. 301585

Very quick delivery. A little TOO Much plastic looking, however it will be just fine. Send your request for review 2-3 weeks after delivery. It will be installed then.I can then send a pic or 2. 123444

  • 7-Way RV Trailer Connector Wiring and Mounting on a 2006 Honda Pilot
  • If you will be installing a 7-Way RV style trailer wiring connector on your 2006 Honda Pilot, to tow your camper, you will most likely need all of the wiring and circuit breakers to complete the installation of a brake controller and power wire for the 7-Way. Our Brake Controller Installation Kit, # ETBC7, contains all of the wiring, circuit breakers and the 7-Way RV connector, # 37185, that you mentioned. I have included a link to detailed installation instructions for you to review, and...

  • Trailer Hitch Recommendation for a 2016 Honda Pilot and 7-Way Mounting Bracket
  • The Curt hitch part # C13146 that you referenced is going to sit below the rear bumper unlike the factory hitch option that comes out through the lower fascia of the bumper. For a 7-way bracket that would attach to the 2 inch hitch tube of the Curt hitch you would want the part # 18156.

  • Mounting Bracket Options For 4-Way Trailer Connectors
  • We do offer a couple of mounting boxes for 4-way flat connectors, but the style differs from the Draw-Tite Bracket, part # 18156. You can check out part # 18145 and part # HM48755. These are designed to protect your 4-way flat connector. I have attached links to our product pages that list the mounting brackets we have for 4-way round and 4-way flat trailer connectors.

  • Size of Tubing Used to Construct Curt Class III # C13002
  • The cross tube of the # C13002 Curt Class III Receiver hitch is constructed of rectangular tubing that is 2-1/2 by 1-1/2. Looking at the front face of the cross tube, the tubing would be 1-1/2 inches tall and 2-1/2 inches deep, so the # 18156 connector mounting box would be a better fit for you.

  • 6 and 7-Way Trailer Connector Mount for a 2003 Subaru Forester Hitch
  • I went out into our warehouse and measured the cross tubes of both the Curt # 12038 and the Draw Tite # 36311 and found that they have cross tubes that measure 2-1/2 inches by 1-1/2 inches. The 6 and 7-Way Trailer Connector Mounting Box, part # 18156, could be installed onto one of these hitches, but I do not believe it is your best option as you would have to install the mount on the bottom of the cross tube. I would recommend you use a 6 and 7-Way Trailer Connector Mounting Box for...

  • How to Attach 7-Way Trailer Connector to 2014 Ford Edge
  • None of the trailer connector mounting options we offer are vehicle specific, so finding a way to attach the connector to the vehicle could involve some trial and error. If you have access to the hitch crosstube, you can use a mounting box like part # 18156. Another option would be a no-drill bracket like # C57202 attached to the crosstube, and then you would use a bracket like part # 18138 to attach the 7-way connector to the no-drill bracket. I have also seen instances where folks...

  • How to Mount Replacement OEM Tow Package Wiring 118253 on a 2010 Honda Pilot with Factory Knockout
  • To secure the 7-Way connector part of the Replacement OEM Tow Package Wiring, # 118253, to your 2010 Honda Pilot, you can use the factory knockout and drill 4 holes to match the four mounting holes on the 7-Way. Use the 7-Way as a template to drill the holes. If you do not want to drill into the bumper, you can attach a bracket to the trailer hitch. You can use the Mounting Box, # 18156. This is a simple no-drill, universal application that includes a clamp to attach the bracket to the...

  • 7-Way Box Bracket for Trailer Hitch Tube Attachment and Metal 7-Way Recommendation
  • We have plastic boxes for mounting a trailer connector like the part # 18156 but none that are made of metal. Plastic would actually be better though since it wouldn't corrode over time or potentially scrape the paint of the hitch off which would allow for additional corrosion. For a metal 7-way socket to fit this the part # PK12703 would be a great option as well. Then for a 7-way that you could install on your trailer that comes with a junction box you would want the part # 277-000141....

  • Trailer Hitch Fit Recommendation for 2017 Honda Pilot AWD
  • Yes, we have the Draw Tite hitch part # 75225 which is a fit for your 2017 Honda Pilot EX-L AWD and would work very well. I attached an install video for more info on how it installs as well. For trailer wiring you'd then want the part # 118679 which is a confirmed fit as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop....

There is a cutout in the rear of the unit for the wiring to pass through when it is mounted. Includes screws for mounting the connector and a steel hose clamp to secure the mounting box to the hitch.

This will upgrade the 4-way flat on your Ridgeline to a 7-way connector. I have attached the installation details for you to check out and also included an image of the fuse instructions. We do not yet have an installation video on your vehicle but the process should be similar to the Honda Pilot demonstration...

  • 7-Way Trailer Connector Mounting Bracket for Curt Trailer Hitch with 3 Inch Square Cross Tube
  • I spoke with my contact at Curt and trailer hitch # C15324 has a 3 inch x 3 inch cross tube. Mounting bracket # 18156 would not fit. Bracket # 18159 would be the better option since it does not reach around 3 sides of the tube, just 2. I have linked a video showing installation to the right.

  • Recommended Locking Hitch Pin and Trailer Wiring Mounting Box for 2016 Sprinter RV
  • For your 2016 Sprinter RV with factory trailer hitch receiver, I recommend the Weigh Safe Hitch Receiver Lock for 2", 2-1/2", and 3" Hitches - 3-1/2" Span # WS05. This should give you the extra length needed to possibly work around that wiring box. If not, then I recommend removing the wiring box and reattaching it using the 6 and 7-Way Trailer Connector Mounting Box for Round or Square Tube Hitches # 18159 or # 18156.

  • What Mounts Can I use for 7-Way 118242 with Hitch 87183 On my 2003 Ford F-150
  • We have a couple different mounting brackets you could use, like part # 18138 or part # PK12711U. You can attach these to the bumper or part of the vehicle. You could also mount a box to the hitch # 87183 using part # 18159 or part # 18156. These boxes use a clamp to attach to the hitch so there is no drilling into the hitch or vehicle.

  • Does 7-Way part # 30717 Fit in Mounting Bracket part # 18156
  • Yes, the 7-way part # 30717 that you referenced is going to fit the # 18156. Both of these are setup for the standard 7-way mounting bolt patterns so they would work great together.

  • Recommended Wiring To Make 2011 Honda Pilot Compatible With 5-Way Trailer Wiring Reverse Solenoid
  • For your 2011 Honda Pilot, I recommend you use the Honda Replacement OEM Tow Package Wiring (7-Way) w/ Circuit Protected ModuLite HD Module # 118253 so you will also have the reverse function you need. This will require you to use the Draw-Tite 6 and 7-Way Trailer Connector Mounting Box, 2-1/2" # 18156. Then you will need an adapter like # TR20141 or # A57WB. With trailer connectors, it is wise to use dielectric grease like # 11755 to keep moisture and debris out of your connections.

  • 7-Way Wiring Recommendation for a 2009 Honda Pilot EX
  • You will need Tow Ready wiring harness # 118253 for your 2009 Honda Pilot EX. The # 118265 harness you referenced is a fit for the 2011 and 2012 Pilot models and will not work on the 2009 models. The # 18156 7-Way mounting box will give you an easy mounting option, as it just straps directly to the trailer hitch on the vehicle. I am including a link to the installation instructions for the # 118253 wiring for you to reference, as well as some general information on wiring for towing...

This bracket fits a 2-1/2 inch square tube hitch and is designed to mount a 6- or 7-way round trailer connector. If you are using a 4-way flat connector and would like an enclosed mounting box, we have the Tow Ready 4 and 5-Flat Trailer Connector Mounting Box # 18145 and the Hopkins Mounting Box for 4-way Flat Trailer Connector # HM48755.

  • The mounting bracket part # 18156 that you referenced will allow the 7-way of the # ETBC7 to attach to it. This would fit your # C13200 as well. Since you have a 4-way already all you would need to convert it to a 7-way and install a brake controller is the part # ETBC7. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.
