Very easy, plugged right into the uscar connector, drilled 2 holes for the bracket, done



by:
2003 GMC Yukon XL

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.

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.

2003 Mercury Mountaineer

This was supposed to be a plug in installation for my 2003 Mercury Mountaineer. No it wasn't. Completely different connector, and the wiring was 2 feet too short. Was able to use it after a bit of clipping and splicing.

Super easy, very nice! Great engineering, couldn’t have been any easier! The girls at etrailer are super friendly and very helpful! Great prices and quick shipping, too!!

Excellent fit, oversized spare tire still fit underneath (285/70r17).



by:

Product I ordered had an inaccurate description. Contacted customer service to return they would not send return shipping label so since the return shipping would have costed more than the part I threw it in the trash and ordered the part needed from another supplier. Needless to say I will not be ordering anything again.

It has been working great, holding up well,the same as the day I purchased it. Great product



by:

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.



by:

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!



by:
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.



by:
2017 Ford Explorer

Always accurate parts and information



by:

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.



by:

Perfect fit, works well

2002 Ford Excursion

My 2002 Ford Excursion 7.3L diesel had the original factory hitch and wiring harness. The quality and heft of the Curt T-Connector is impressive. I bet I get years of use without problems.



by:
2023 Honda Passport

Bought this because of the split 4 pin and 7 pin connectors. I’ve had so many 7 pin to 4 pin adaptors and would forget that I let my son or son in-law use it and had to buy another one when I needed it. This will stop me from the need to buy another adaptor, good for me not good for my son and son in-law when they come over to borrow the trailer. LOL, who am I kidding I’ll still go with them to the store and buy another one.



by:
2024 Ford Bronco

Great product and very helpful staff! Thank you!!



by:

The actual trailer hitch was fine but the wiring kit was not the right kind. When I called to get a return authorization I was told that more than one half the cost of wiring kit will be deducted from my return for postage. I have never had to pay for returns to any company before. I will not be recommending your company



by:

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.



by:
2005 GMC Yukon XL

I like how it has both 7-way and the 4 pole connectors. Looks nice too!



by:
2007 Ford F-150

Great product & customer service



by:

Great fitment. Had a little difficulty getting to the right version of this but the amazing customer service at ETrailer helped me get to the correct one. Thank y’all! I love any business that’s not named after a rain forrest!



by:

The pigtail was easy to install and looked great. The problem was that it didn’t work without taking it to someone to program the computer to recognize it. That cost was going to be more than twice the cost of the connector. I still have it back in the box. I purchased a four wire flat connector and wired it up.



by:

Plugged right in and makes for a professional look



by:
2017 Nissan Titan XD

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.

Product just like it said it does, delivery just took long but is free delivery so is good, packed box came like bit out from the people delivered but localy everything works good

  • Replacement 7-Way Plug for 2009 GMC Sierra 2500
    There are no retaining clips and zip ties or duct tape may not hold the connector so the best option and what I recommend is to replace the factory 7-way of your 2009 GMC Sierra with the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55774. This will plug right into your truck's factory tow package port and give you a permanent solution so you won't have to worry about a loose connection.

    It sounds like you are needing a 7-Way connector on your 2011 Ford F-150 Raptor. For this, I recommend the Curt T-Connector Vehicle Wiring Harness # C55774. This will plug right into the factory port on the truck, which is what appears you have found behind the rear bumper. Once the connection is made, you will have a fully functional 7-Way and 4-Way connector on your F-150. I have attached an installation video that you can check out.

  • 2015 Ram ITBM F87 Fuse Blowing Troubleshooting
    I did a little bit of digging on the F87 ITBM blowing on your 2015 Ram Tradesman and mostly it looks like the issue is related to the wiring to the 7-way connector. There is a short on the 7-way wiring most likely either right behind the 7-way or the pins of the connector are dirty. If the 7-way has seen better days one solution would be to replace it with the part # C55774 which also comes with a 4-way attached to it.

  • Why Won't 4-Way and 7-Way Connectors Work with Trailer on a 2018 Jeep Grand Cherokee
    Sometimes after installing some aftermarket wiring the Jeep "tow package" wiring circuit will need to be activated. This can only be done at a Jeep dealer and it sounds like this is what is going on. You can verify this by checking to see how your current wiring is connected. If everything is splice in then it would bypass all of the factory wiring and I am not sure why you would be testing and getting a signal but your Jeep isn't communicating with your trailer. If the 4-Way and 7-Way...

  • Can Curt 7-Way and 4-Way # C55774 Fit 2019 Chevy Silverado 2500HD
    The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55774 that you referenced is a fit for your 2019 Chevy Silverado 2500HD and would install easily by just plugging directly into the 7-way wiring that's present at the rear of the vehicle. I am not totally sure what you mean by taking the pin out of the two covers though. But this would attach to the lower portion of the rear bumper.

  • Could Factory 4-Way of 2003 Ford F-150 be Cut Off After Installing Curt # C55774
    The problem you could run into if you cut the factory 4-way of your 2003 Ford F-150 off when installing the part # C55774 is that the wire still would be active and could short out if you are not careful. If you went this route you'd need to tape each wire up well so that they wouldn't short. Other option would be to just leave the 4-way and tape it up and out of the way.

  • How to Know If Vehicle Wiring Will Be Overloaded By Connected Trailer Lights
    If you were using Curt T-Connector # C55774 and wanted to make connections at both the 4-pole and 7-way at the same time you could add the current draw of the two connected trailers/devices (like a tailgate light strip) to know whether this would exceed the rating of the circuits. The online manual for your 2015 F-250 indicates multiple separate fused circuits for the various trailer light functions.

    Thank you for the purchase of the towing equipment for your 2015 Jeep Grand Cherokee. Since you aren't able to get the wiring to send power for the Curt T-Connector # C55774 and you have checked the fuses it sounds you need to take your Grand Cherokee to your nearest Jeep dealer and have them activate the tow package wiring circuit. This isn't always the case but is sometimes necessary.

    It's not uncommon for a single trailer wiring circuit not to work but if most of the circuits are active and only one isn't it wouldn't be the issue you described of having to have a dealer turn on the tow package. If this were the case none of the trailer wiring would be active. Since we know the problem isn't on the trailer that leaves the issue being on the tow vehicle side of the wiring. A very common reason for this is a dirty or corroded connector for that circuit which can easily...

  • Curt T-Connector Vehicle Wiring Harness for Factory Tow Package Length
    I went to the warehouse to measure and the 4-pole pigtail part # C55774 measures about 18 inches from the back of the 7-way plug to the end of the 4-pole connector. The wiring of the 4-pole connector that sticks out of the wire loom is about 6-1/2 inches. The overall length of the wire loomed wiring from the back of the 7-way plug to the end of the connector that plugs into the vehicle's factory port is 15-3/4 inches.

    The 7-way blade trailer connector is the most common connector for use with trailer brakes. The 6-way is typically only used with horse/agriculutral trailers but even then the 7-way is still pretty common. For a 2002 Ford F-250 we have the part # C55774 which gives you a 7-way and a 4-way.

    You can use a 7-Way and 4-Way connector at the same time just as long as you are not overloading the light circuits. If your camper has a lot of outside lights like running lights, and brake/stop/turn lights then the lights that perform the same functions on your boat trailer might be a little dim or the fuses might blow on those circuits. For a 7-Way and 4-Way connector that you can use at the same time I recommend using the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package...
