Quickly and easily install a 7-way and a 4-way trailer connector on your Ford F-150 with this custom harness. Connector plugs directly into OEM tow package wiring harness - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, on the driver's side.
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.

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.
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!!

Great. No problems.
Excellent fit, oversized spare tire still fit underneath (285/70r17).
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.
Very good, fit perfectly

It has been working great, holding up well,the same as the day I purchased it. Great product
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.
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!
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.
Always accurate parts and information
Perfect fit, works well
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.
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.
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 and very helpful staff! Thank you!!
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
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.
I like how it has both 7-way and the 4 pole connectors. Looks nice too!
Great product & customer service
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!
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.
Plugged right in and makes for a professional look
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

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.
