Perfect fit. My truck was not equipped with a tow package so I was a little worried it wouldn’t fit. The wiring and plug were already there with a cap on it to seal it from dirt/water. Took the cap off and this harness snapped right in place. Also installed an etrailer hitch and new bumper. Very happy with the products and the installer tools and information provided by etrailer.com.

Great product. Installed on my 2018 Jeep GC. Because of dual 4 pin and 7 pin connector I don’t need an adaptor when swapping out trailers/camper. Clean look to it as well.

2018 Audi Q7

This only fits 2017 Audi Q7 - strange my Q7 is 2018. I had to try 6 different trailer harnesses finally " lucking out" finding this one - it works. The next problem it does not bolt to the 2018 Q7. I have designed and create an adapter plate that will match the C55774 to the 2018 Q7. No instructions show how to connect C55774 to an Audi but if I had a Jeep there lots of the same instructions on the web.

I am having a problem with the install of the three Curt trailer components I purchased. I intentionally bought all of the same brand assuming that they would work together. The problem is that the Curt wiring harness (part# C55774) is too long and rigid. When the 7-pin connector is installed in the bracket that comes with it, it measure 5 inches until the black wire protective sleeve bends (to go under the hitch receiver frame). The no-drill bracket (part# C57202) is supposed to attach the harness bracket to the hitch. But it is only 6.5" long, and the hitch tube is 3" wide. So with the bracket attached to the hitch, there is only 3.5" of space left to mount the harness bracket so that the screw holes line up. I am disappointed that this is the case, especially as I called etrailer to check that the parts I was ordering would work together. It looks like I will have to discard C57202 and drill two holes into the bottom of the hitch and mount the harness bracket directly. This is what I wanted to avoid - having to drill holes.


Comments
The 7-way bracket that comes with the wiring harness part # C55774 is designed to be installed with the wiring harness bracket hanging below the no drill bracket part # C57202. Since you are worried about the loose wiring I would recommend using some wire loom such as part # 459075-1 to protect your wiring and zip tie any slack with zip ties part # DW05726-25. I know this is not the option you wanted but I feel it is better than drilling into the hitch.

This product works flawlessly plugging right into the existing wiring system. My only issue was that I was shorted two screws to mount the wiring bracket to the hitch bar bracket.

The product is fine. It took almost 2 weeks to receive the product, and when it got here the box it was in was fine, but the contents of the product package was open and screws, nuts, and bolts where loose in the mailing box. It was also missing one of the nuts, I'm guessing as a result of the package being open.

Sorry this happened to your package. Customer service will be reaching out about the missing hardware.

2018 Nissan Titan

I have a 2018 Nissan Titan, and while the connector was a perfect fit for connectivity to the factory connector. The Curt T-Connector wiring harness was about 6 inches short from connecting to the factory harness when mounted on the trailer hitch bracket. So, I was forced to mount it on the opposite side by drilling holes in bumper.

2007 GMC Sierra

I bought this one after my 2007 GMC Sierra Classic after being rear-end while on a trip. The body shop said I was looking at three weeks to get in what the adjuster had authorized so I talked to my insurance agent and she told me that they'd deduct it from the claim and that I could get what I wanted up to the adjuster's cost estimate and they'd reimburse me, so after a bit of searching I found this one. I switch between trailers, spme with brakes and some without and for years I've carried an adapter, so really liked the idea of having the 4-wire socket built in. I truly could not be more impressed! Super easy install, quality product, and works perfectly. And less expensive than what the body shop was going to charge for the stock replacement. Can't go wrong with that kind of a product!

There was no place on the new hitch to bolt the end to, which was a disappointment. For now I sip tied the end to the hitch in an area where it does not move.

Harness was easy to install. The truck came prewired. It just needed the adapter. We dremeled our the back of the bumper (2019 Titan’s have the cut our outlined on the back side already). We had to dremel 2 side prices off the harness, but it slide right now. Then we drilled through the plastics bumper cover and the metal on the bumper and bolted the bracket to the bumper. The 4 point is just fished between the license plate and the bumper. It was easy and it now looks factory. Very happy with how it came out! Install was a cinch!

The wiring harness connected fine to the Nissan Titan 7 pin plug. I used hose clamps to mount the new 7/4 pin. Only issue was I discover I need the relay kit to enable the brake and turn signal to function all the trailer lights.

If you have multiple trailers that either use a 4-way flat or 7-pin round connector and get tried of having to use an adapter go with this setup. I've had one on my other truck for a couple years and no problems with 'em thus far. You can technically use the old existing mount on the receiver hitch itself but the 4-way will dangle unless you ziptie it up.

    When it comes to towing components like hitches, you're always going to be limited to the capacity of your lowest rated components; so adding a higher rated hitch to your vehicle isn't going to increase your towing capacity or the payload.
