very easy to install. it is a rather tight fit on a Chevy traverse. Allows a factory install of aftermarket hitch by using GM harness # 25910884 ($68.00) . Harness comes with snap in wire ties that go in holes on cross frame of rear bumper. Vehicle to connector harness is located to the rear of right rear tire between outer body panel and tail light . Use flash light and look up. Cord fits E trailer Vehicle end plug 40975. Need to drill two holes in cross frame for bracket. It all snaps together very well. Also need to add 3 relays in engine fuse box. GM13502753. This is gray relay 1/2 in square and has 2750 market on top. this eliminates splicing delicate factory wiried and hassel of hot wire from battery. Bumper skirt snaps back into place and hides hitch totally on 2013 Chevy Traverse. 87284

Chas,Where did you mount this part on your Traverse? I want to mount it to my 2010 Acadia but I cant find a good place to mount it? Can you send me a picture?I already bought the gm factory harness to install along the cross frame.

I installed it to the left of the receiver. trimmed some of the plastic on bumper trim that holds the removable access cover for the hitch. Y ou need to be careful not to cut away the slots that hold cover in place. The installed hitch and electrical are completely concealed.. Note there are several blogs on the Traverse owners forum. I also bought the correct tow switch,and relays that fit in the engine compartment fuse box. The ranny is already programmed at factory for tow mode. One fellow posted photos of the whole prcedure and listed all part numbers. I also ordered the tranny cooler from E-Trailer. Be sure to use a digital thermometer to be sure you hook up to correct lines. You will need to find correct fitting on internet. It will take some time to remove most of the front clip to have room to work.Incidentally I drove Traverse up on a coulpe fo 4X4 to be able to work under it., I used a floor jack to raise up hitch to align it.chas

Here's some snaps of my Hopkins #40975 installation. I can confirm that it's an identical replacement for the 2014 Silverado 1500 trailer-light blank insert, no bracket required. It took me 30 seconds to plug the Silverado's OEM 7-pin round connector (located inside the blank insert) into the #40975 Wiring Kit and snap it into the cutout. Then I tested the flat 4-pin outlet of the #40975 with a 5 dollar 4-pin LED tester from West Marine, and all light functions tested good. Shweet! To remove the OEM blank plug, it helps to reach behind it and pinch the two spring clips holding it in place... same with the #40975 if it needs to be removed for some reason. When I ordered the part from eTrailer, your site had a comment, "This will not fit your vehicle. See below for compatible parts," or words to that effect. Maybe take a look at that and remove the comment, as the #40975 is an exact fit for 2014 Silverado 1500, no bracket needed. Thanks, eTrailer team! 120915


Comments

Although I havent towed since installing the Hopkins Pollak wiring kit since I installed it a year ago, I have tested the 4-pin connector for proper function using a 4-pin LED tester from West Marine and it checks out okay. Recently I inspected the kit for water intrusion mentioned by one of the raters, and I found no evidence of moisture inside the dual-connector compartment. On installation, I did make liberal use of the dielectric grease that accompanies the kit. Good product, easy installation, and great price.

Because of my particular placement of the plug mounting bracket, I had to spot weld the bracket to my hitch. Once I did that, I let it cool a bit, that simply snapped my connector in, plugged my chevy 2500 hd wiring harness in the back and now I do not have to mess with plug adapters for my flat wired trailers. Very, very, easy installation. Additionally, this new plug solved a bunch of issures with blinking trailer lights or lights that were not working at all. Thanks for your courteous service, great price, and fast shipping. Forever a customer, tom 56598


Comments

All my comments in my review almost a year ago are still applicable today. Our winter here was terrible with all the rain, snow, and ice. My lighting circuits on my trailers and boat worked great...whereas in the past, they performed poorly in any kind of wet conditions.I always recommend to my friends who have had wiring problems with their trailers to start at the truck with a solid performing plug with appropriate adapters for the type of trailers you will be using. It will eliminate a host of problems with lights not working properly.Thanks once again for your courteous service.

I just received my package from Etrailer.com and it was nice to open the box and have the right part/part I ordered arrive. Opened up the box staged my parts and started the install. It was very easy with the instructions that were sent and the video on their site that anyone can do this install with no issues. Hitch was on in no less than 15 mins from opening of the box to final torquing of the bolts. The customer service at this company is top notch. I have never had anyone from a company email me before after ordering from them like I did with this company and in business today you are seeing less and less of this type of customer care and service. AWESOME job Guys and Gals I will buy all my accessories from here. 90754

Comments

It appears there is an engineering design defect in this product - at least when installed on my 08 F250. Water from Michigan weather - i.e. rain, snow and car washes continues to find its way into the plug, corroding the contacts and causing a wiring fault. No Im NOT backing into water to unload a boat, Ive removed, cleaned and dried the inside at least three times, covered the contacts and connection points with dielectric grease and carefully sealed the unit w electric tape. Last week, I sprayed the outside of the plug w/ flexible rubber seal yes as seen on TV in my fourth attempt at stopping the water from getting into the plug. This past week, while on a 500 mile road trip we made it through torrential driving rain without experiencing any connection issues. Im keeping my fingers crossed and hoping I dont have to take the plug apart, now that its sealed in the rubber coating!

David S - 06/03/2014

We hope the rubber coating takes care of the problem. If not, we've got a couple of suggestions. You mentioned dielectric grease. If you weren't already, you can be pretty liberal with the application. You can fill the socket and push the connector in and wipe the excess that squirts out. If all the voids are full of grease, there's no place for the water to go. Second, on most of these types of connectors, there is a rubber gasket on the vehicle side that usually stays in, but will sometimes pull out when you remove the cap or the previous 7-way connector. If you still have the cap or old connectory, you may want to check for the gasket.

Excellent quality. Only took 5 minutes to install. Outstanding customer service!! Ordered online on Friday and received via USPS on Monday, with emails letting me know the order was received, the item was shipped, and one that stated that the company had received information that the item had been delivered. And each one was signed by an individual. If only all companies operated this way. 93531

My adapter arrived last night. Took about 45 seconds to install on my 2015 Toyota Tundra Double Cab SR5, 4.6L 2WD . Fit perfectly to the already existing wiring in the bumper and snapped right into the hole. It's not listed as OEM for the Tundra, but sure fits like OEM. When I called the dealer to inquire about the part, I was quoted $279 and the parts guy couldn't guarantee the fit--comical. I haven't checked it with a test light yet, but it fit so well, that I cannot imagine it not working properly. ETrailer's customer service is perfect. Thanks guys! 198443

Not a single issue with plug adapter. Ive pulled many, many times this year and I love that I can hook up both of the most standard type plugs. Thanks, ETrailer!

Trailer plug unit (Pollack 7 & 4 pole for my F-250 was broken by the car wash. Called the dealer and they wanted double what e-trailer sales it for plus I had to special order and that took too long to ship as I needed it immediately. I went online and found ETrailer.com and they had the exact replacement device that was identical to what the manufacturer had installed. I ordered it and asked to have it within a set timeframe and e-trailer did exactly what they said they would do! The lady I spoke with Cathy was on the stick with the entire order and follow-up. The Etrailer staff then followed up the very next day of delivery. I have just installed the plug this morning so it has to be tested but do not forsee any issues as it is the exact replacement which worked great before. I am very impressed with the service here and will most definitely buy from them again as well as refer my freinds and business associates. I manage a commercial fleet as well as work with many other contractors who have trucks and trailers and there is always the need for something in this category. Great job ETrailer, you have a new long term customer. 42962

2015 GMC 1500 bought new no hitch or trailer plug went to dealer for trailer plug could not find plug in parts system said they would have to call Tec support. Left disappointed. Found E TRAILER had part (in stock) and video how to install found excellent for someone that doesn't have much mechanical skill (I'm 20 years in automotive). Have not been able to install yet due to ice build up from snow on frame. Very pleased and will be telling everyone about ETRAILER and will be ordering when I need parts, 235434

I bought this as a replacement for the existing trailer connector on my 2013 Tundra. The mount was different than what I had (mine wasn't angled) but I was able to snap the wiring connector into the existing mount so I didn't have to change anything or drill holes. Installation took less than 5 minutes. Wiring harness on backside connected perfectly. Excellent value considering Toyota would only sell me an entire wiring assembly which was over $200 (if I recall correctly). eTrailer ordering, shipping and follow up from customer service confirming delivery of the part couldn't be beat! 194541

Hello George: I recently ordered the following for my 2005 Silverado : 13322 Class III Hitch - Gm 1500/2500 Pickup Curt Angled Ball Mnt - 2 Rise, 4 Drop, 10-1/4 Long Pin And Clip For Class III Iv And V Trailer Hitch Receiver Pollak 7- And 4-pole Connector Socket W/mount Bracket I got free shipping and received the hitch in 4 days. I thought I would save some money and install it myself not knowing what all it entailed. So I reviewed the U-Tube video and figured it wouldn't be so hard. The video was exactly representative of my vehicle. Everything bolted right up. To those that wish to do this I will caution you the my biggest challenge was removing the ball that was rusted onto my bumper. The other things you may run into is removing the spare because sometimes the lowering mechanisms are seized due to rust like mine was. Both the ball and spare tire hoist had to be cut off. Other than those two items the install went smoothly. The hitch looks awesome and as though it was factory installed. Thank you for a quality product and an excellent price. 311420

I searched for days for something like this to work on my 2014 Chevy Silverado that did not have the factory tow package. I couldn't find anything, until I read a previous review with photos from another reviewer. Dont be fooled by the "item photo" and the "sideways position in the photo" , the bracket shown is for mounting elsewhere if desired. This item was a simple unplug the fake factory blank plug and plug in this real one installation you can do at home. This item fits perfect. Take a look at the previous review photos etc. Regular shipping was very fast. 144612

The part came in ahead of schedule, was exactly what I needed, and works flawlessly. The connection looks indestructible. Installation was absolutely painless. The self-drilling screws worked perfectly in the pre-existing holes too. Thanks etrailer. 62429

This is just a follow-up to the review I made more than a year ago. The connector for my multiple trailers is still working without problem. I do not expect to ever have to replace this connector, but if I did, or if I get a new truck, etrailer would be my connection supplier. They provide genuine plug-

I recently bought a new truck, as my other one was over twenty-two years old. On the old truck, I installed both the trailer hitch and the light hook-up. A lot has changed in the last twenty-two years. The agreement on the new truck was that it come with a trailer hitch, but I failed to include the light hook-up assembly. I thought that if you got one, you got the other! WRONG! I was informed that I would have to purchase and install the light hook-up myself. I went on line to etrailer.com and ordered the light hook-up. It was at a reasonable cost and arrived within a week of being ordered. Was a bit surprised when I opened the box and just found a plug-in type hook-up assembly. I was expecting a lot of wiring and other connectors. The installation took about a half an hour and was very easy to do. Again, a lot has changed in the past twenty-two years. I am very pleased with the part, price, ease of installation, and the change that the truck manufacturers have made in the area of tow package hook-ups. 384686

This is a plug-in replacement for my 2010 Ford F-150 with factory installed trailer package. I had this exact same connector but someone unclipped it and stole it. Ford Parts wanted over $100 for a replacemnt (they included the entire rear bumper harness that I did not need). I had the cutout on the hitch that exactly matched this bracket and the blue socket that you see in the optional pigtail available for this product (see attached photo). I snapped this dual connector into my existing cutout - fit perfectly. Did not need to use the included bracket. So if your factory connector is damaged or stolen, use this as a snap-in replacement. The only difference is it says "Pollack" instead of "Ford". I called Hopkins before I bought and they said they supplied a lot of the OE parts Ford uses. 55449

Thanks for the follow up Rachael, the part is working great, dont use it very often but still needed to have one. You guys are great! Will recommend your site to others needing parts. Glad that a Company can still value there customers now a-days, does not happen as often as it use to.

I really like this trailer plug since it converts a standard 7 Wire plug into both a 7 wire and 4 wire. It plugs directly into the factory wiring harness. it comes with everything you need to mount it (bracket and self tapping screws). It was an easy install. My 05 Chevy Tahoe had the factory 7 wire outlet bracket, I left that in place and mounted this bracket just to the left of it. I highly recommend this product. 437664

Hitch was easy to install, no issues whatsoever. Quality looks very good. I also installed the Pollack 7/4 pin connector socket with the mounting bracket. I used nuts and bolts rather than the included sheet metal bolts. No issues with it either and it also seems to be of high quality. The receiver hitch tucks up under the rear valance/bumper very nicely and imo looks better than the factory Jeep hitch. One thing is that, as noted on a couple of the installation videos on this site, one has to go to the Jeep dealer and get the Hitch Program 'turned on' in the vehicle computer before the trailer lights will work. I have yet to do that. All Jeep Grand Cherokees come with the towing package, you just have to get the computer reflashed so it will recognize the lights. 341571

I really like this product. I like that the 7 blade and the 4pin plugs are internally wired. It is truley a 'plug-n-play' unit and even has corrosion preventitive in the pins. The reason I did not give this kit an 'excellent' rating is the mount bracket is too short. This required that a use a 1 inch spacer and longer bolt to attach the mount so the trailer plug could be inserted. 31977

Shipping was on point, no hassle from picking the correct part to adding in cart to check out all the way to actually receiving my product. Once I got it the installation it took like 2 minutes literally. The only issue I have is that the support Brackett is a "L" shape bracket and the 2016 GMC Sierra's don't have anywhere to actually bolt it into, however, the manufactures flat Brackett works all the same just connected the 7way port into the harness of truck then pushed locked it into the bumper. All in all was done in under 2minutes. Very please thus far 295995

I noticed that you had a video on installing this product on a 2004 Silverado, and a 2006 Silverado. So I'm thinking that should be easy on my 2005. NOT SO! You have to install the bracket on the part of the bumper where there is space. But in doing so, the large piece of round channel causes a big problem. So, what you do is drill holes, then put plug into the connecting wiring harness. Then you have to run the self tapping screws into the bracket while holding the bracket in your hand with wiring attached. Once they are started into the bumper, you will need to use and 1/2 inch wrench because of the clearance issue to get them tight on the driver side of the bracket. Socket will work on the other side. And I thought it would be simple. But it did work 57400

This was a great addition to the hitch I bought for my 2011 Grand Cherokee. I was able to plug it right into the factory harness for a perfect fit. The only issue you may have is the trailer lights won't work until you get the computer flashed from the dealer to tell the Jeep it has a towing harness attached now. 54337


Comments

I have a 2012 Jeep Grand Cherokee that came without the tow package, but which still had the 7-way connector at the rear. This trailer connector socket attached easily to my hidden hitch, and connecting it to the Jeeps 7-way was a snap. If your trailer signals and brake lights do not work after installing this socket on the 2012 WK, youll probably have to take it to the dealer for a body control module re-flash, and itll cost you around $100.

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

This is a great idea. I want to be able to use either type of plug--this does that. But I'll have a big hassle mating up the other side. I'm looking for a connector or else I'll have to solder and carefully shrink wrap all the connectors. it would be great if a pig tail was provided. It is designed for OEM applications for Ford Dodge and GM. I am putting it on a Volvo 240 Wagon. Most of the time I pull very small boat trailers. I have one bigger trailer that is 1900 lbs and wired with a 7 prong connector so I can use utility lights and trailer backup lights. This is a very nice quality connector. I just think it is STUPID not to sell it with a wiring pigtail. 18334

Good quality and installation was easy enough. It would be nice if the clocking of the notch for the rear connector from the vehicle would line up with the notch for the trailer connector. This would make wire tracing a lot easier. The wiring color-to-color connections for a 2002 Sierra do not match the connections for the 2002 Silverado as shown in the video but a few minutes with a voltmeter and the wife flipping levers was all it took to find the right match-up. 120751

I have a Ford F-250 truck on which I needed a replacement Pollak 7 and 4 pole connecter socket. The original socket was manufactured by Pollak although the Ford name was engraved. I found the exact part that I needed on the etrailer website. I went to the parts department of my local Ford dealer who had the part in stock. The parts guy said they would match etrailer's price. When I told the him what I would pay for the connecter at etrailer he said that the cost was half of what the dealership pays for the same part. I ordered the part from etrailer and it arrived within a few days. In the future I will buy the parts I need from etrailer. 236297

Bought this to replace the stock blank on my 2015 Silverado 1500 WT. Super simple to install made even easier after I removed the rear license plate and reached through to unclip the blank (Better than trying to reach up from under the bumper). The wire harness unclips, after removing the white locking tab, and snaps right in to this new socket. It can only plug in one way. Replace the white locking tab and the new Pollak connector socket snaps right into the cut out from the blank. No use for the supplied mounting bracket. That's it. Oh, you might want to replace your license plate and you are done! 205775

by: Keith H.06/04/2016


I like the product but the mounting bracket is different from the bracket which it replaced on my old 7 blade socket. This bracket will require a different location because my original bracket had a bolt on one end, a hole in the middle so the bracket would fit over a bolt head and washer, and the other end had a tang that stuck into a hole to keep it from moving around. The old bracket also had more drop below the mounting surface. One other issue is the locking in between the connector and the wiring socket. I can't get it to lock in so I will have to improvise there also. I like the product. 256752

The HM40975 is an excellent product It appears to be well made and fit perfectly on the Draw-tite hitch I ordered. It was installed on a 2015 Jeep Grand Cherokee. While the Jeep is factory wired and the factory plug on the harness fits the connector set perfectly, you have to go to a Jeep dealer to have the circuits that enable the wiring to operate. The local dealer charged me $63.59 to "Flash the Body Control Module" . This turns on the logic that controls the power to the rear trailer hitch. Once the logic in the Jeep was turned on, the connector is perfect. I highly recommend this product. 277252

I continue to be pleased with this product. Its worked out as well as the factory installed assembly I had on the last Jeep I purchased and it cost me a lot less.

The Pollak Custom Fit Vehicle Wiring Connector, # PK11916, is a twist-in design that is designed to fit into the pre-existing cutout on your truck. I am sending a video link that will show this part being installed on a 2009 Chevy Silverado. The Hopkins 7 and 4-pole Trailer Connector, # HM40975, will also work on your vehicle, but the socket will not be able to be installed in the pre-existing cutout...

  • Trailer Left Turn/Brake Lights Not Working After Installing Hopkins # HM40975 4- and 7-Pole Socket
  • First, verify that the Silverados own drivers-side light functions are working correctly without the trailer connected. Next check your fuse panel in the engine compartment. Make sure the fuse for the trailer wiring circuit is good; this is, according to my research, the number 1 fuse and should be 40-amp. Also check the trailer left turn fuse, number 10, which is 10-amp. If the fuses are good then move on to the Hopkins # HM40975 4- and 7-Pole Socket that you referenced. This part...

  • 2006 GMC Sierra Trailer Wiring Not Supplying Battery Charge on a 2005 Slide in Camper by Six Pac
  • If you have a 7-Way connector on the rear of your 2006 GMC Sierra, the number 4 contact, in the 1 o-clock position, looking inside the connector from the rear of the vehicle, should be the 12 volt hot wire contact (see link). Check this contact with a circuit tester, item # 3808 if needed. If you do not have power to this contact then you will need to determine if there is a blown fuse. This fuse is under the hood in the power distribution box (see link). There should be a 40 amp fuse in...

  • 7-Way Wiring Configuration for Slide-In Truck Camper
  • Your slide-in truck camper does not have electric brakes so the blue brake circuit wire from its 7-way connector is not used. All other lighting functions as well as 12V auxiliary power will be maintained on the other circuits. Please refer to the linked photo for the standard wiring/function configuration for RV-style 7-way connectors.

  • Replacement 7-Way Trailer Connector and Wiring Harness for a 2007 Toyota Tundra
  • We do have the Pollak 7- and 4-Pole Trailer Connector Socket, # HM40975, if it is just the plug part that is broken on your 2007 Toyota Tundra. If the wiring harness is damaged, you could use the 4 Foot Pigtail Wiring Harness, # PK11998, to replace the area that is broken. The wiring configuration for this harness can be found on the product page in the Specs section.

  • Mounting Bracket for Curt Hitch on 2016 Ford F-350 Super Duty
  • In order to attach a connector to the Curt Hitch # C15810 you would use a bracket such as the Curt # C57202, and attach your connector's mounting bracket to that. An example of this is shown in the video I've linked which shows the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975; you can forward to the 0:45 mark to see exactly how this would work. I've attached a link to our page with each of our mounting brackets for you, as well as an install video of the Curt...

  • Can 7-Way Trailer Connector Accessory Circuit be Used to Power Trailer-Mounted Winch
  • The 12-volt accessory circuit lacks the amperage to power a trailer mounted winch. Your best bet would be to either install a 12-volt deep cycle battery on the trailer, and use the 12-volt accessory circuit to keep that battery maintained, or use a winch wiring kit like part # SW2008 and connect the winch to the vehicle battery. If you use the 12-volt accessory circuit to maintain the trailer-mounted battery, I would recommend installing a battery isolator, like part # TR118665. The...

  • Installing a Brake Controller on a 2004 Dodge Ram 2500 with a Factory 4-Flat Trailer Connector
  • Yes, I can most certainly help you. It sounds like you have a factory 4-Way connector at the rear of your 2004 Dodge Ram. So you will need 2 things in order to have the lights and the trailer brakes functional on the trailer. First, you will need a brake controller installed in the cab of the truck to control the electric trailer brakes. Second, you will need a 7 and 4 way Installation Kit, # ETBC7 to allow for all of the functions (lights and brakes) to work on the trailer. For a brake...

  • Tekonsha Primus IQ Trailer Brake Controller # TK90160 Shows No Connection to Trailer
  • Your Tekonsha Primus IQ # TK90160 brake controller will display the NC message (indicating the trailer is not connected) for any of several possible reasons: if the trailer is not connected, if the connector has corrosion, if there is an open circuit on the brake line, if the trailer brake magnet loses its ground connection to the trailer frame or if the brake magnet is malfunctioning. Although trailer lighting functions are carried on the same 7-way connectors, since they are on separate...

  • Adding 7-Way and Brake Controller to 2012 Ford E-Series Van with Factory Wiring and No Tow Package
  • If your 2012 Ford Van has the proper connectors at the back where the harness you found terminates then you could use # 118261 to add a 7-Way. Or you could use # HM40975 and hardwire it to the wires you found using # PK11998. For a brake controller if the connector under the dash is active you would use wiring harness # 3034-P. I recommend the P2 brake controller # 90885. This controller is easy to set up and use and it is reliable. I have linked an installation video that should help.

  • Activating 12-Volt Accessory 7-Way Circuit on 2007 Ford F150
  • Since your F150 had the 4-pole connector, the towing circuits are most likely not fully active. To activate that charge circuit, you will need to install a fuse and relay into the fuse box. The fuse is a 30 amp in location # 106, and the relay goes in position # R05. These positions are shown in the fuse diagram on page 277 of your owners manual. You can obtain the relay from your Ford dealer or your local auto parts store.
