Once installation is complete, the connectors will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket is included to keep the connectors secure.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 7-pole and 4-pole connectors - to help prevent corrosion.

The Curt T-Connector vehicle wiring harness fit as recommended by the etrailer.com customer service representative. I wanted to be sure the electrical connector package would fit my Draw-Tite hitch, and it did. The instructions were straightforward, although there were no screws or nuts to attach the metal bracket to the hitch. I had to supply those. I believe they should have been part of the kit. The installation video on the etrailer.com site was very helpful.

This connector worked perfectly on my '06 Chevy Trailblazer. It was very easy to swap it out with my original connector, and the addition of the 4-pole plug makes it easy to eliminate the 7 to 4 pin adapter.

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.

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.

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.

Working well. Have used the four prong plug only but am glad to have the 7 way available if needed.
by: Dylan04/10/2021
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.

Perfect fit, works well
by: Danny07/31/2020
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!

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.

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.

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.

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: Michael 05/03/2023

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: Rhonda04/17/2023
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

- Which 7 way Wiring Harness Do I Need for a 2018 Ford Transit T-350I'm not sure what that plug is for exactly, but it's not anything related to the towing wiring, so that's not the wiring that you're looking for. If you don't have the factory tow package on your vehicle, you're not going to have a way to plug something like the Curt # C55774 (which is the correct harness for the T350 with the factory towing package)- this would utilize a US car connector plug to connect a 7 way. With that said, the Tekonsha # 22114 wiring harness is the correct harness...

- Can 7-Way and 4-Way Both Install on 2016 Nissan FrontierYou can install both a 4 and 7-way in place of the 7-way kit part # 118281 that fits your 2016 Nissan Frontier. For that you would also need to go with the part # C55774 and install it instead of the included 7-way of the # 118281 and you'd be set.

view full answer... - Is Ford Replacement OEM Tow Package Wiring Harness Compatible With 2005 Ford F-350 Super DutyThe Ford Replacement OEM Tow Package Wiring Harness, 7-Way (Super Duty) # 118243 fits the 1999-2001 F-350 and is not confirmed to fit your 2005 F-350. Instead, you can use the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Pole Flat Connectors # C55774. This plugs directly into your OEM tow package wiring harness behind the rear bumper on your truck.
view full answer... - Which 7-Way For 2001 Ford F-350 Super DutyBased on how you described it, I'm guessing your 2001 Ford F-350 Super Duty needs a different part than the # C55774, but what does the plug look like? The correct 7-way is going to depend on that, as the Curt option you mentioned is a replacement 7-way, and has a round plug, while the other has a more square plug. If you take a look at the accompanying photos, you can see the plugs for the two 7-ways that could work for your '01 F-350: - Square Plug: Ford Replacement OEM Tow Package...

- Fuse for 12 Volt on 7-Way of 2016 Ram 3500I took a look at an online copy of the owner's manual for your 2016 Ram 3500 and it did not specify the 12 volt terminal for your 7-way. However, it did specify "Trailer Tow Receptacle" in Cavity F30 in the Power Distribution Center in the engine compartment which seems is the likely fuse you are looking for. I recommend checking your copy of the owner's manual to confirm.
view full answer... - Can 7-Way and 4-Way Both Install on Trailer for Separate Wiring CircuitsWhen you say rear lights do you mean like utility lights so that you could see in the dark? If so you could just use the 12 volt accessory circuit of the 7-way to accomplish that. But aside from that you certainly could have two different connectors on your trailer for two different sets of lights. For a 7-way plug all you'd need is the part # 277-000143 and then for a 4-way part # A25W2GWB for 25 feet.
view full answer... - Parts to Added 7 and 4-Way to 2019 Toyota SR TacomaThe Tekonsha 7-way kit part # 22117 is the correct kit to add a 7-way to your 2019 Toyota Tacoma if it did not have factory wiring and will work either way but if you have a round connector already present for a 7-way you could get by with just the # C55774 and you'd be good.
view full answer... - Troubleshooting Trailer Turn Signal Not Working With 2015 Ram 3500You are correct it is your 2015 Ram 3500 because you wisely hooked up the trailers to your wife's SUV and there wasn't an issue. Since there are no blown fuses or bad wiring, it seems likely the issue is simply your trailer connector. Check your connector for corrosion, which can be green or white in color. A build-up of corrosion can interfere with the signals getting through the connectors so if it is present you are going to need to clean the corrosion if possible or replace the plug...
view full answer... - Recommended 7 Way Replacement for a 99 Ford F-250 With Factory PortThe Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Pole Flat Connectors # C55774 will be the correct fit for your 99 Ford F-250. The round connector you have paired with the controller in the cab of your truck confirms this. The # C55774 also has a 4 Flat that mounts on the side of included bracket, so you do not need to keep track of an adapter, like the # PK12716.

If you do not already have wiring, I recommend Curt T-Connector part # C55774 if the Yukon has a factory 7-way. If the Yukon does not have a factory 7-way setup you need part # C59236 for a 4-way flat. If you need a 7-way on the rear of the vehicle for a brake controller, I recommend to use C59236 4-way flat and part # ETBC7L which comes with a 7-way plug and circuit breaker. Plug the existing 4-way...
view full answer... - Does the Curt T-Connector Vehicle Wiring Harness for a 2012 Buick Enclave Come With FusesThe Curt T-Connector Vehicle Wiring Harness for Factory Tow Package part # C55774 is a fit for a 2012 Buick Enclave with factory tow package. Therefore, the fuses and relays should already be present. If you don't have the factory tow package then you may need to supply your own fuses and relays as they are not provided.
view full answer... - 4-Way Extension Recommendation for Rear of Ford F-250 For Towing Second TrailerThe Curt T-Connector part # C55774 that you referenced would be the first component you'd want. This will give you a 7-way and 4-way active at the rear of your truck. This will allow you to run a 4-way extension from the truck to the second trailer to activate the turn signals. For an extension you could use the part # A40W42B which is a 40 foot section of 4-way wiring that includes a male 4-way and then to the other end you could attach the part # HM48030 and you'd be set.

If your F-150 did not come with a factory 7-way connector you will need to use the # ETBC7 if your truck has a 4-way connector already installed, or the 4 Pole # 18252 and # ETBC7 if your truck did not come with a factory trailer connector. The # ETBC7 will plug into your...
view full answer... - Replacement 7-Way Trailer Connector For Rectangular Tow Package Connector on 1999 Ford F-350For the rectangular connector, you'll want to use the Curt # C55243 which includes the necessary fuses and relays to activate the tow package. The # C55243 doesn't include an integrated 4 pole connector like the # C55774 does, but you can use an adapter like # PK12716 from Pollak. I'm typically not super-enthused about using adapters, but Pollak currently makes the trailer connectors for every domestic pickup right now, and they build a great product so this should be very reliable for...
view full answer... - Availability of 2-Foot Long Trailer Wiring Harness for MotorhomeI can come up with a solution or two for you, but the cable on the Curt # C55774 that you looked at measures about a foot long, so unless you have some slack in the motorhome's tow package harness that would make up that extra foot for you, you would need to make some modifications to an existing product. The first alternative would be to use the # HM40975-11998, and cut off the US car connector on the motorhome and hardwire the pigtail from this connector into the tow package wiring....

view full answer... - Troubleshooting 12v Power Wire Not Working on Trailer Connector on 2013 Ram 1500I would start by checking the wire for the 12v power supply directly behind the 7 way connector on your 2013 Ram 1500, which when looking at the back of the connector will be at the 1-o'clock position. You'll want to use a circuit tester like the # PTW2993 to see if you're getting power on the wire itself. If you're getting power to the wire but not on the corresponding pin of the 7 way itself, the 7 way connector has likely gone bad and can be replaced with part # C55774. If you're not...
view full answer... - 2015 Ram ITBM F87 Fuse Blowing TroubleshootingI 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.

I am not sure if the trim on an Altitude is much different than the Laredo but I can say that it doesn't look like you will need to. You can check out the attached installation video to confirm.

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.
