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. .

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

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

Received it today. It would not install on my trailer as delivered, but with minor adjustments, I was able to set it up so it would work great. 30361

  • 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...

  • 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.

  • 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.

  • 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...

  • 6 and 7-Way Trailer Connector Mounting Box Recommendation for Draw Tite Hitch on 2004 Jeep Liberty
  • I spoke with my contact Draw-Tite and he informed that the cross tube is 2-1/2 inch by 2-1/2 inch. Because of this I would recommend you use a 6 and 7-Way Trailer Connector Mounting Box # 18156. I attached installation instructions and an installation video for the # 75128 for you to check out also.

  • 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.

  • 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...

  • 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.

  • 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.

  • 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...

  • 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 # 18136 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 have...

  • Brake Controller and Installation Wiring for a 2015 Toyota Highlander
  • 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. This is a proportional brake...
