Video Transcript for Pollak Replacement Bracket for 7 and 4 Pole Trailer Connectors Review

Today we'll be taking a look at and installing our replacement mounting bracket for Hopkins seven pull and four pull trailer connector sockets, Part Number HM40978. This is what it looks while installed using our line bracket here. It's nice and firm so it's not going to go anywhere. You can see this truck is shaking because I've pulled on it. This is the connector. This is how this mounts up in here. If you lost or broke your bracket, this is your option to go with instead of buying a whole new kit.

I'm going to pull this through. It connects our seven pull/four pull in place. Set that through and it just snaps in place. That's not going to go anywhere and you have full access to both sides of your trailer connector. Let's show you how it's installed. To make this work, I'm going to be using our long bracket, so clamp around our frame, giving us a place to mount our bracket here.

We use our bolt here, pass that through. On the back side I'm going to put a washer and then the nut that comes with it. These washers don't come with the kit, but I suggest finding some because the holes are kind of big on the back and you want a nice place for these to grab onto. Holding the nuts on the back side, the star washer kind of does the work for us. I'm just going to tighten it down. Then I can grab my clamp and go around our hitch to hold it in place.

The clamp just goes through the bracket and I feed it through itself right here as much as I can. Here's the bolt. I hold it away from the bracket, and when I'm ready to tighten it I push the bolt towards it so that the teeth can grab it. Now that I've got my bolt the way I want it, I'm going to go ahead and start tightening it. I'm going to kind of tuck this up behind the hitch so it doesn't grab onto anything while we're going down the road. Confirm it's nice and tight, and I can break that off or fold it, which I'm just going to fold it, and it's nice and tucked away behind the hitch.

That's our look at the replacement mounting bracket, Part Number HM40978.Speaker 2: You can find this and everything else right here at etrailer.com. What's up man.

Exactly what I needed to relocate the trailer plug on my 2019 4Runner. I had to use two spacers I made out of an aluminum tube that I already had to get the clearance from the bumper facia but this worked perfectly. The plug just snapped out of the original factory bracket and snapped right into this bracket. Now I don't have to lay under my 4Runner to plug in and unplug my boat and camper.




by:

I removed the bumper to install a lift gate. The bracket allowed me to install the OEM trailer connector. Perfect fit!




by:

Awesome fit on my 07 f150 the only problem was I couldn't open the doors on the front after being mounted flush. Easy redneck fix tho grabbed a 5/8 nut and a longer 1/2" bolt and nut and used the 5/8 as a spacer between the mount and the stock holes. Looks a million times better then being held up with zip ties like before.


Comments
Still holding up perfectly used plenty of times

By moving the plug over it makes it easier to plug in a adapter without it working loose. Only took about 5 minutes to install and well worth the time and the cost of the bracket




by:

Don’t get me wrong I loved it the price was right and I needed one couldn’t find it anywhere but I knew etrailer would have it, I have a 22 Jeep grand Cherokee L limited and the hitch and wiring is hidden behind an enclosure I did have to make some modifications and grind a little notch in it and install it backwards in order for it to work but it ended up being the cats meow thank you etrailer like always you’re awesome, it was five stars but doing a little work I thought four




by:

The Original single plug was hung too low and scraped the driveway entry as I entered or left the driveway. Your bracket allowed me to relocate the better plug assembly closer to the bumper much higher than the hitch receiver.




by:

built from sturdy gauge aluminum n enough paint to prevent corrosion for years to come.. my 7/4 pin combo plug doesn’t fit snug in factory opening.. traced by hand n etched out 3 layers of rubber gasket material.. provided a better install.. used drywall style plastic wall anchors w/#8 screws to anchor the mount on bottom of pre-drilled factory holes beneath the bumper.. used a Nissan T99T8-9BUOA 7 pin wiring harness.. all works well for’22 Frontier..




by:

Excellent service on the part of the saleslady, Jamie. I appreciated having her telephone number so I could call her back if any problems developed.

As things turned out, in the past couple of days, my 7-and-4 Pole Trailer Connector Socket became dislodged in the wind when I was driving my truck and became lost. Consequently, I had my wife, Irene, order one using her Paypal Account. It is order xxxxxxxx, and we just ordered this today - Saturday the 5th. When one orders this socket, it comes with a bracket. I do not need another bracket since I just ordered one. I am pleased to be able to get these items, though.




by:

Fit my trailer connector perfectly and met all my expectations. Very happy!


Comments
Continues to perform exactly as it should. A good purchase and value.

Just what I was looking for @ a good price and speedy shipping! Thanks!

Looked everywhere for a bracket to reposition the trailer sockets on my 2018 4Runner. Factory placement had it buried under the body. My boat trailer wiring could barely reach the 4-flat socket and I had to actually lie on the ground to plug in my lights. This was the only product I could find that fit my needs. I did have to cut two 1" spacers for the product to clear the plastic bumper so I could access the connector sockets. It did fit without drilling any holes which was important to me. I just needed to buy longer bolts. Happy with the results - no more lying on the ground to plug in my trailer!




by:

Part fits exactly as is should.




by:

It works. I needed to relocate the factory connector from underneath my 4Runner to a place where it was actually usable. This did the trick.




by:

Worked as advertised. The self taping bolts were challenging so may suggest bolts with nuts but I did get them to work with a little patience.


Comments
Still holding strong a year later

This company is the best
They are
tech savvy is so helpful if you’re stuck or unsure you are to yourself to give a trailer a try


Comments
Product is fine works well after one year

by:

Perfect fit. Quick and easy ordering, and fast delivery.




by:

Bought this a year ago. Easy to install with Mopar wiring kit onto my Jeep. Still doing what it’s supposed to do.




by:

this bracket is heavier, meaning it should last longer than the original. Excellent workmanship, perfect replacement. etrailer hit it out of the park with this one. Thanks


Comments
After a year, its has held up well thru the elements in north central Pa. A purchase well worth the price.
Ron - 09/05/2020


by:

Exactly what I needed and a perfect fit to match an OE installation.




by:

Perfect fit




by:

The bracket worked perfectly with my Mopar 7/4Pin plug on my 2013 Jeep Grand Cherokee. It snapped right into the mounting bracket like it was custom built.
Service and shipping were from eTailer were excellent


Comments
The bracket has held up well. No problems what at all.
Dakotajohn - 01/26/2015


by:

Bracket fit really well on my 2015 Ford transit. The self tapping screws it comes with are cheap and you will be lucky if they will work. Pretty much need to predrill for the screws which isn't a huge deal. The factory Ford 4way/7way fits perfectly in the cutout




by:

Fit perfect.




by:

Awesome products. Did exactly what the product videos showed to do and in less than 10 minutes broken trailer plug bracket fix. I will be recommending your services and products. Thank you for a simple quick fix.


Comments
Very well
Jeremy C - 02/14/2017

This is made to hold my OEM Ford F150's trailer wiring connector. It hasn't fallen off get, so I suppose it does about a good a job as you could expect from such a part.


Comments
The plug is still hanging in there with heavy ranch use. It does a simple job and continue to do it. I would buy again if I had the need to and would recommend to others.
