Video Transcript for Draw-Tite Trailer Connector Mounting Box Installation

Today, were going to be taking a look at as well as showing you how to install the Draw-Tite 6 and 7-Way Trailer Connector Mounting Box for round or square tube hitches, part number 18159. This vehicle already has a 7-way with the 4-way plug adapter on it but you can see how loose it is as well as that its mounted to the underside of the hitch so it hangs down really low to where it could be hit and damaged. Well be removing this plug right here and were going to be adding it to our new 6 and 7-way mounting box. Since this is a round hitch on this particular vehicle, well be using the box somewhere in this position like that. Now weve gone ahead and removed the original bracket that was on this vehicle.Heres what youll get with the new 6 and 7-way connector box. You get the plastic box here.

Youd get a hose clamp as well as some screws to attach your 6 or 7-way plug to the box itself. Now weve got all of our wires pulled down. The 6 and 7-way plug is loose. Were going to need to disconnect a couple of things in order to install our box. Well go ahead and unplug the 4-way as well as to remove the ground screw.

Now well be able to pull the plug and the wires down. Well then take our new mounting box. Feed our ground wire through as well as any additional wires. If you look in there close, youll see that it lines up with the holes predrilled in the box.Were going to be mounting our bracket somewhere in this area here. Now, this right here is cut out for a square tube.

Were going to put this on a round tube though because it is designed for both. Depending on how large the round tube on your receiver is, you can trim the edge of the plastic here on both sides to contour around the hitch itself. You could do that on both the front and the back side. You kind of see how theres a dimple or its got a spot where you trim out to. It just gives you an area where you should trim down so well go ahead and trim that out so that it fits nice and snug up against our hitch.Now, Ill just go ahead and take my razor knife, go along the contour here.

Just trim this section out. Go ahead and repeat that over here on the other side. We went ahead and pulled the wire and the plug back out while we we're trimming this to make sure we didnt accidentally cut a wire. Lets go ahead and test fit our bracket back up on our hitch now that we have it trimmed. As you can see, it fits nice and tight around the round part of the trailer hitch. Now well go ahead and mount our 7-way plug into our bracket here. Depending on your exact plug that youre putting in here, the kit does come with these smaller screws that can be used to attach it to the bracket.Since our plug is a lot thicker, we had to get some longer screw. Were going to be using a screw that looks like this to attach our plug to the bracket. Now we put our plug back in the bracket. Were going to go ahead and use our longer screws. The ones that come with the kit just arent quite long enough with our plug. Then go ahead and take our wires. Feed them up and under and then choose the exact location where we want our bracket to be mounted. Then take the hose clamp and go through the slot on the bottom and come out the slot on the top. Then take the hose clamp and feed the one end into the other end. Go ahead then and tighten down the hose clamp.The hose clamp is secure. You can see the bracket is nice and tight against the hitch. Now the excess hose clamp, you can just trim off using a pair of tin snips. Now that our bracket and plug are mounted, all thats left to do is reconnect any wires that we may have removed during the installation. In our case, well be reconnecting the 4-flat to the back side of the plug and reconnecting our white wire with the ring terminal which is the ground. Once we have our connections made, well use a couple of zip ties to secure up any excess or loose wiring. The inaudible 00:05:48 bracket works great on straight hitches but as you can see here, our hitch has a big curve or a bend to it so this works really well on this style hitches that helps get the plug facing towards the middle and it doesnt put it in a strange angle.When the plug comes off of your trailer, itll help line it up easier. It gives you plenty of clearance and youre also not having to screw into the bottom or rear face or your bumper. It allows you to attach it directly to the hitch. Another nice feature of this box, our mounting box is that its made of a plastic so you wont get the rusting that many other brackets will cause. Youd get many years of life out of this bracket. Thatll do it for our quick review and installation of the Draw-Tite 6 and 7-Way Trailer Connector Mounting Box for round or square tube hitches, part number 18159. .

6 and 7-Way Trailer Connector Mounting Box for Round or Square Tube Hitches - 18159

Perfect for '08 Toyota 4Runner. I installed a Curt receiver hitch on my 2008 4Runner and once installed it interfered the factory 7pin trailer connector. I extended the wiring harness and this mounted box worked out perfectly. Great product!

This did the trick for me. Just what I was looking for it fits round or square tubes. It hides under the bumper off to the side where I want it it mounted. 110% happy with my order. Fast shipping Ps. A small part was missing in the box. But After I contacted the company they sent me a new one practically overnight. Top notch company and they stand behind their products. You can tell by the attached pictures I am extremely happy with this product for the past year so far and “it still looks great”.

The perfect solution for an odd hitch. Works great looks good. See picture.

Has worked well. The only real solution for this difficult hitch structure on this Lexus 400h.

This is an awesome piece. It was a much better alternative than a plug hanging under the bumper. It comes set up for a square tubing style hitch, but there is a notch molded in that makes it easy to cut it away for a round tube hitch. My only complaint was the hose clamp. It was not like a normal one and I could not get it to stay tight. I replaced it with a stainless one from [local hardware store] and it has stayed tight since. The other nice thing is the unit protects the rear of your trailer plug from moisture.


Comments
Still looking and working out great! So much better than one of the hanging plugs!

This installs easily and looks nice. I used it on a round tube hitch so I had to trim the plastic. That's not a problem as there is a score mark on the plastic. It cut easy and cleanly.

On my 2009 Ford Flex. Thanks etrailer.com. Great service and fast shipping. I got my order the next day!! Way to go!

etrailer.com always has a solution to my trailer problems! This worked out great and is such a cleaner look!

The holes didn't come close to lining up with the seven prong outlet. Also, the face was small compared to the outlet. Needs to be a bit larger.

Makes a nice looking job on a round tube hitch. Keeps receptacle out of the way from dragging too. Lightning fast shipping as a bonus.

The product page says this unit is a universal fit, which is not true. It will be too big for a class one hitch. I made it work with a minor modification.


Comments
After a year, the straps will need tightening, as the whole thing has become loose and rattles around. I would not recommend for a class one hitch.

Just what I needed to make accessing the plug easy

I used this to mount a 7-way connector to a round tube Curt hitch. It fit very well and is more secure than I expected. I can highly recommend this mounting box.


Comments
Still perfect a year later!

Plastic is very flimsy. Can't tighten securely. It moves slightly when plugging in and removing the trailer harness plug.



- 18159
by:

The mounting box worked perfectly on my round tube hitch. I like that it is off to the side as it allowed me to mount it just under the rear bumper, which looks good and made it easy to route the wires up for connection.



- 18159
by:

This worked great, I didn't want the bulky 7 pin plug in showing from the back of my wifes Qx 60 infinity so I bought this item and rolled it under vehicle and you cant see the connecter.



- 18159
by:

Love this product since this housing made sure our 7pin plug housing could be mounted higher and. It in the provided location in the hutch bracket. We used this housing so we could have it higher on the hitch so it will be protected. Live and recommend it to all!

Contrary to another reviewer, I thought the plastic to be pretty sturdy (it's got pretty thick walls). It mounts securely with the hose clamp, and gives a very clean look when installed. The recessed circular cutting guide on the inside made it easy to round out the notches to fit my round (rather than square) hitch crossbar. The only thing I had to modify was to widen the hose clamp slot on one side so I could feed some of the extra length back inside the box.

This product did not work as advertised. Install video shows to use the the bolts (screws are to short) that came with my 7 pin plug adapter by drilling bigger holes in the box. These holes ended up right next to the side walls of the box allowing NO room for the nut to fix. Had to purchase bigger screws & drill bigger holes in by plug adapter to make it work. You need to get rid of the install video.

I can't review the working order of this product, because i wasn't able to use it, due to not being able to mount it in a location that worked for me. But it's a good solid product that would've worked great. And shout out to Etrailer.com, awesome website, great product information, nice selection, good prices and fast shipping. Great place to find real product reviews.

Great Product! However did have to modify it a little for my application regarding 2005 Dodge Grand Caravan. If one mounts the product as the angle is cut out. It will drag from past experience with 4 other Caravans. All you got to do is cut a square opening to fit 2 inch square hitch bar. This allows for the wires to go over hitch bar (on non exhaust side) and not under to be exposed to low clearance. This product is a great solution and mounts real easy. Puts my hook up away from exhaust. Will have picture later.

Used in conjunction with a Curt C15302 receiver and a Pollak PK11893 7-way socket on a 2003 Chevy Silverado 2500HD. The only issue I encountered is that the stock GM wiring harness plug makes for a bit of a tight fit, and you have to force the harness into the tight space. Time will tell if it holds up.



- 18159

The Curt hitch,complete with wiring harness and the 7 pole adapter with 4 flat plug were all easy to install and conveniently available thru etrailer.com. The installation video on their web site was complete and confidence inspiring. The go to site to install it right. Thank-you etrailer.

Bought a car with a round pipe trailer hitch but no wiring and no good place to mount the 7-way connector. We were thinking about spot welding something until I found this. Worked great, looks nice and professional.



- 18159

Very difficult to bolt the 7-connector to it, but once done it fits well and does exactly what I wanted it for. A quick dremel to cut the curve to fit a tubular hitch. Ordering and shipping was painless and fast.
