Fit no issues tight and quality. Spot on. 2011 gmc 2500hd fit right in the factory light plug in. Those that don’t have the 7 way connector already in it this adapts.


As advertised, came quickly. Doesn't fit the rear TDK bumper without modifications to the bumper or plug, no fault of the plug.


Worked well so far, kind of a pain to install because of the splicing required.

Still working good.
Dean S - 04/25/2022


This worked great on my 2008 Serria. It didn't have a plug from the factory so I removed plug in bumper and install connector. Wiring was all ready for it from factory.worked great.


Very happy to do business with this company, they had the exact part I needed and I couldn't believe how fast it was shipped. This will definitely be a go to company when I need parts quickly.


This connector arrived fast and was very easy to install. Took about two minutes to put in. It seems to be of very good quality.

2013 GMC Sierra

Broke my trailer electrical socket on my GMC pickup, I’m 1,500 miles from home waiting for the snow to start melting to go home. The local GM dealer wanted over $70.00 for replacement part. Found this one at for $16.95. I had it sent priority mail as mail has been slow here in AZ , received in six day and took less than five minutes to install. Hate to leave AZ , but home in SD is calling. We will be be back next winter. Thanks to etrailer for saveing me money I’ll need for gas home.


Took five minutes to install. Works gr eat.


Very easy...Installed in about 10 seconds. Product did not completely cover the holes through the bumper that existed from the factory harness insert. So you can see light a little bit of light around the product.


After spending a little time online figuring out how this connector attaches to the factory hitch (push the tab, twist about 1/4 turn, pull out far enough to reach wiring harness connector), I ordered one from etrailer. When I got it, it took me all of 5 minutes to remove the broken connector and install the new one. Upon examining the OEM connector, which says "GM" on the lid's outside, it says "Pollak" on the inside, so the OEM part was built by this aftermarket company. No wonder it fit so well! BTW, the original broke because of cockpit error, not because of manufacturing defect.

2008 Chevrolet Silverado

Perfect fit for my 2008 Silverado. Identical to the adapter used in my wife's 2007 Suburban, except hers says "GM" and mine says "Pollack." This is all assuming it works, I haven't hooked a trailer up to it yet.

2007 GMC Sierra Classic

perfect match!


Looks to be good quality. Easy to install.

the old connector by depressing the keeper, turning it counter clock wise about a quarter turn, slide it out, depress the keeper on the wiring harness connector and unpluging the unit. Install the new connector by pluging in the wiring harness connector, sliding the unit through the bumper hole and turning it about a quarter turn clock wise to lock it in place. It took less time than writing this.

After a year, I still believe this product is well made of high quallity products. It is operating well as I expected it would. Thank you for building and selling this product.

Couldn't have been any easier. Hardest thing was opening the package??.


Worked exactly as described

2007 Chevrolet Silverado 2500

Old electric plug in on my 2007 Chevy 2500 was worn out. Cord from RV would not stay plugged in. Went on line on E-Trailer, ordered a new part for GM vehicles, when it arrived, it took me about five minutes or lees to remove the plug all I needed was a small regular blade screwdriver. New part woks fine. This is the 2nd or 3rd time I have ordered from E-Trailer. I have always been satisfied. Thank you Ken Hill

Still working great

2007 Chevrolet Silverado New Body

I haven’t installed this yet, but it looks right and based on purchases/product history have every reason to believe it will be. Unlike some websites I’m able to find what I’m looking for easily here.

Thank you for your review. This item works with a factory 7 way. Here is nice video for reference while you are installing:

Trailer parts arrived quickly, were well packaged & fit exactly. will be my first call for additional trailering needs.

works well, no problems, fast delivery

2001 Chevrolet Suburban

My wife and I built a trailer for our kayaks. Once done, the electric test failed and we traced it back to this part on our 20 year old, faithful Suburban. etrailer had the part, suggested that it may not be an exact fit and made buying easy. Once the part arrived, it tested perfectly and fit just fine. Thanks etrailer for having this part and your quality service.


Replaces plug with broken cover tab. Old plug matches photo. Correct model year replacement not exact duplicate but fits cutout and wire harness. Average price. Very fair shipping fee.

Looks good, fits good, works fine.
ARP - 09/20/2017


Very easy to install this connector and is a solid quality product



They are all still performing well.

  • Location of Fuses In Power Distribution Box To Install Brake Controller on 2008 Chevrolet Silverado
    Sometimes the fuses are already installed from the factory, but if not the fuse slots are in the front of the box. I have attached a picture that shows the location of fuse slots. I have also linked a video installation of a brake controller on a 2008 GMC Sierra and an FAQ on brake controller installation on a 2008 Sierra/Silverado.

  • Underhood Connections Needed to Power the 12 Volt Power Source Circuit of a 2006 Chevy Silverado
    It sounds like you still need to make a few underhood connections on your 2006 Chevy Silverado 2500 before the 12 volt power circuit of your vehicle will be activated. Check out the FAQ article I attached that shows how these connections are made. Basically you will have to install a couple fuses and run a wire to a positive power post and you should be good to go.

  • Replacement 7-Way Trailer Connector for 2003 GMC Yukon XL with Factory Tow Package
    The # PK11916 you mention is a direct replacement for the OEM 7-way on the 2003 Yukon XL. The connector will only work on vehicles equipped with the factory tow package (like yours), and would twist into the bumper opening as shown in the photo I edited for you. Once twisted into place, the existing harness will plug into the back of the # PK11916 plug.

  • Troubleshooting a Blown Running Light Fuse on a 2011 Chevrolet Silverado
    If the tail light fuse blows only when you connect the trailer, then you probably have a short in the running light circuit on your trailer. If this is the case, then I would recommend starting at the trailer connector and checking for any corrosion or damaged pins. If you find corrosion, then you will want to remove the wires from the connector as corrosion could have spread inside of the connector. You should also check the vehicle side connector for any corrosion or damaged pins and...

  • Which Fuses Control Trailer Lighting Circuits on 2003 Ford F350
    Like you said, it sounds like you have a tow package fuse that is either blown or missing. The fuses are located in the power distribution box under the hood or in a secondary, smaller box located on the firewall. Your owners manual or the lid of the fuse box should feature a diagram showing which fuses protect which circuits. From what I have found online, check fuse location # 1,3,4 and 16, making sure the fuses in those locations are present and not blown. If the plug was faulty, you...

Once the 7-way is free of the bracket, you will see a clip on the top of the connector. Simply depress the clip, and pull the damaged socket apart from the connector. Push the replacement onto the connector until the clip clicks into place, and replace into the bracket. I have a video that will also show how this is done. The video...

    I would first test the 12 volt wire hooked up to the RV-Style Trailer Connector, # PK11916, to see if the wire itself is carrying power. If it is, then there is something wrong inside the connector such as a loose connection or its wired to the wrong pin.

If you are still not getting 12 volt power then you know something is wrong between the wiring at the rear of the truck and where...
