Today, we'll be reviewing part number HM 40975. This is the Pollak 7 and 4 pole trailer connector socket with mounting bracket. The product is manufactured by Pollak and distributed exclusively by Hopkins. It's going to offer you a 7 pole and a 4 pole trailer connector for easy connection, as well as the mounting bracket and the hardware. It has high impact, ABS plastic construction with a stainless steel spring for easy and convenient cover operation. The rubber gasket is going to provide weather resistant design. You see there, that they're very easy to open and close.

It does include the mounting bracket for easy snap in socket installation. The mounting bracket is made from a black epoxy coated steel construction and it mounts directly to the bumper with the included screws. This is designed to replace your factory 7 way connection on Chevrolet, Ford, GMC and Nissan trucks and SUVs. This can be used to add a connector to a 2003 and newer GM pick ups and SUVs. It's going to be an exact replacement for Chrysler and Dodge vehicles with 7 pull sockets from the factory. You see there, that we've got the easy connection, here, at the bank so you can get all your wiring in place.

It's also got the snap lock design, so it snaps right into the bracket. Once you have your connections made, you just feed this in through the bracket. It's going to snap into place. It's going to hold it nice and tight, very secure. On this side, you're going to have the 4 pole flap. On this side, you're going to have your 7 way connection.

It's got the 2 mounting holes up top for the 2 included screws. That's going to do it for today's review of part number HM 40975. .

I ordered DrawTite hitch #76031 along with Tekonsha Wiring #118273 and HM40975, 7 and 4-Pole Trailer Connector Socket for my 2018 Nissan Pathfinder SL. I ordered on a Thursday afternoon and the merchandise arrived the following Monday evening (with free shipping and no tax). The hitch arrived in excellent condition with no scratches or scrapes and was packaged very well. The total for my order was a great price! This also included a tube of dielectric grease and a brush. To get a factory hitch would have required an expensive "Technology Package" at a cost of over $2000 or a dealer install which would have cost over $1000. I did the install of the hitch myself. It would have been far easier if I had a lift to raise the vehicle off the ground, and a helper to hold the hitch in place and get the 6 frame bolts started. I used an ice chest to prop up one side of the hitch while I got the bolts started on the other side. Watch the videos from etrailer before doing the install. I did have to trim about one-eighth of an inch off the corner of the gasoline vapor recovery box on the left underside of the vehicle to get the hitch into a position so that the holes in the hitch lined up with the weld nuts on the frame. I used a rotary file on the end of my drill to do this. The 2X2 receiver does barely touch the bottom of the rear trim on my Pathfinder but did not require cutting the trim to get it to fit. The Tekonsha #118273 Factory Wiring was not difficult to install. The etrailer video on how to install this item was not as good as it could have been. The installer says he is going to make the 2 vehicle connections inside the left-rear of the vehicle "by feel," which may be fine for someone who knows what he is doing, but was not helpful to me. I pulled back the trim on the inside left rear to make these 2 connections. You should definitely make ALL of your wiring connections BEFORE installing the hitch itself. If you don't, it will be very difficult to reach the connectors outside the right rear of the vehicle if the hitch is already in place. BE WARNED about this. The HM40975 connector was very easy to install and by having it you will not need to use an adapter to use a 4-way flat trailer connector. I used 2 stainless steel bolts to fasten the bracket into place instead of the included self-tapping bolts that were in the kit. This item is well worth the small cost. I am completely satisfied with my purchase from etrailer and will not hesitate to recommend them highly. Both George and Adam at Etrailer were very helpful. See the picture of the completed install on my 2018 Nissan Pathfinder SL. 566326

2015 Audi Q7


Scratched my head for a while, trying to find a quality way to connect this vehicle end 4/7 wire socket to my trailer ready (almost) 2015 Audi Q7. Finally decided that it really didn’t need to be bolted, but could be hose clamped to the existing heavy duty Audi bracket. Mounted it sideways with a 1” diameter and a 3” diameter hose clamp. Be sure to use a 3” clamp with lots of serrations that all it to tighten it down a lot. You’ll need to drill out the small hole of the supplied bracket to allow a clamp to fit through it. The other hole is a slot, and works unaltered. Small clamp on bottom, large clamp on top. You’ll also need to relieve a small spot on the trim piece to make room for the 4-wire door to o-en freely. This is marked as red on one of the pictures. Looks good and should work good! 567819

Great quality products at a great price. Fast shipping and delivery. Easy installation with the included instructIon sheets. The 7 and 4 pole trailer connector provides the flexibilty to pull my teardrop trailer which has brakes and a 7-way plug or my utility trailer which has a flat 4-way plug without adapters. Fantastic customer service.etrailer.com has a great selection of products for your vehicle and traveling needs. 570294

Plug and play, couldn't be easier! Decent price too. Only 4 stars due to the ridiculous self-taping screws they expect you to put through 3/16" steel (just guessing on the thickness - it's 1/8-3/16 best guess...). The install video on the site shows them using nuts/bolts/lockwashers to install it, which is what I did. This product should come with that arrangement instead of the self-taping screws, in my not-so-humble-home-installer-opinion... 554683

This product is fantastic! I needed a new trailer connector after the original one on my truck got damaged in an accident. Installation was super easy and anyone could have done it. The only thing that might make it hard is if the frame of your car does not have pre-cut holes for the provided screws to go through. This product fit my 2000 Ford F-150 perfectly and i was able to use the old hole from the manufacturer's trailer connector to mount this one. I just used the old screw and nut and it fit fine! I would highly reccomend this product if you are in need of a trailer connector or just an updated one that has both 7 and 4 pole. 548603

It came with it's own bracket, which is a plus. It was compatible with etrailer.com's part number C56357, which is also a plus. The self tapping screws being the only hardware coming with the item was a disappointment. I just installed etrailer.com's part number 76301 hitch receiver which has a mounting plate for brackets like this. The self tapping screws, which might have been effective, wouldn't have looked "professional." After finding some hardware which worked, it went on smoothly and fits well with the rest of the assembly. 538985

Installed on 2017 Jeep Grand Cherokee Laredo and Draw-Tite hitch. Setup was super easy using factory connection. Now just have to have Jeep dealer activate the trailer towing feature to get it to work. Couple quotes for $140.00 to flash computer. Seriously I asked. Oh well. I'm knocking it down 1 star because if you look at the video that etrailer has for installing this product, they installed on a hitch that had the mounting bracket on it and didn't use the self taping bolts. It seemed at least to me, there were/would be nuts and bolts provided with the kit (along with the self taping bolts). At least for me that wasn't the case and I had to piece together the hardware. 505920

Good product. Sturdy, nice feature to have the 4 pin and 7 pin plugs, rather than using an adapter. Plugged right into my 2001 Tahoe wiring which was nice. Everything works as it should. My ONLY issue, is actually with etrailers installation video. We drilled the holes in the bumper, same as the video, and got everything installed. The vehicle wiring plugged into the connector at an upwards angle. This caused it to hit the hitch body before it was fully seated. We found we had to mount it to the hitch, because in the video, they have a "valley" hitch, that has more of a bend to it, than the factory round hitch. We ended up mounting it to the hitch itself. Works great. So for the product, 5 stars, for etrailer on this one issue, 4.5 stars. 206247

  • Troubleshooting Electric Trailer Brake System on Trailer Towed by Chevy 2500 Series Truck
  • Discovering why the trailer brakes are not getting power will be a process of elimination. I am not aware of what you have and have not checked, so I will describe the whole troubleshoot process. Start with the brake controller itself. Is it properly adjusted and leveled (if necessary) according to the instructions? Is it getting power? To determine if the controller is receiving power, you can use a circuit tester like part # 40376 on the black wire that feeds the controller to ensure...

  • The OEM wiring configuration of all Chevrolet, Dodge and Ford vehicles, as well as Nissan and Toyota, is the same, and is identical to the pattern shown in the photo I have attached.

Many times we see vehicles come in with the wiring on the vehicle changed because the person has a trailer that is wired incorrectly. Instead of changing the trailer wiring to match the industry...
