Video Transcript for Curt Wiring - Trailer Connectors - C58044 Review

Today we're going to review part number C58044. This is the Curt vehicle wiring harness with the 4-way flat trailer connector. This part does come with these quick splice connectors also. This a 4-way flat trailer connector at the back of your vehicle, this is the vehicle end. Powers your trailer's signal lights, it has a nice rubber molded connector and it uses a bonded wire to provide maximum durability. It is a very simple installation. As you can see right here on this end it has the pigtails.

Basically it's hard wired to your existing wiring. You just include these quick splice connectors for easy splicing of these wires. They do give you three of them for three wires, the white wire is a ground so that you do have to connect to a good clean ground. Again the application on this is for vehicles with the two wire lighting systems. The length of this wiring is 60 inches. The wire gauge that they use in them is 14 gauge and the configuration basically if you'll notice the green wire is the right turn and brake lights, the yellow is the left turn and brake lights, the brown is the tail lights and the white is the ground, which is the standard wire colors in a 4-way. That should do it for the review on part number C58044.

This is the Curt vehicle wiring harness with the 4-way flat trailer connector. .

Curt Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 60" Wire Lead - C58044

Average Customer Rating:  4.7 out of 5 stars   (97 Customer Reviews)

Wire your vehicle to tow a trailer with this universal, splice-in wiring kit. Includes 4-way flat connector, 60" of bonded wire and necessary installation hardware. Designed for use with 2-wire electrical systems.

Very easy to install, hardest part is putting the trunk liner back in place. Watch the YouTube video to get the correct wire colors.



by:
1997 Pontiac Grand Prix

Wire harness works fine but had no instructions, not even a identifier for which color wire does what. No ring terminal included for the ground wire. I think an end cap should be included on the harness due to the fact that there is power at the plug end any time the vehicles lights are operating. I ordered connector cover 20112, fits well on this harness.


Comments
The 4 pole trailer connector part # C58044 is designed with a green wire, yellow wire, brown wire and white wire. The green wire wires into the right turn wire of the vehicles wiring harness. The yellow wires into the left turn signal of the vehicles wiring harness. The brown wire wires into the tail light signal. The white is the ground wire that needs to be grounded to a clean bare metal surface on the vehicle. A ring terminal that accepts 14 gauge wire such as part # DW05737-1 can be used to ground the white wire. If you would like an end cap on the 4 pole connector I recommend part # 20112 by tow ready to protect the end of the connector. I have also attached a wiring help article to assist with the installation.

Ran this from the front of the 5th wheel and back so I could pull my other trailer. Another job well done...... Thanks


Comments
Harness is still like brand new. The cover cap keeps the contacts nice and clean when not in use. Would buy again anytime.
James - 03/24/2021

by:

Will all I can say is it's a well-built good-looking product. It was very easy to install.And easy to wire it up.follow the instructions that you get am 71 years old and I did it All in 45 minutes.
When I was ordering this product customer service went out of their way to help me in any way they could.
I would recommend this company to anyone they are very pleasant people to do business with.and the shipping was right on time



by:

Had an embarrassing issue with one of the quick-splice connectors breaking - would recommend soldering all wires for longevity.



by:

Was nice to be able to print out the text of the installation video. Clear and concise.



by:

I'll start by saying this arrived with my hitch in just a couple of days. It installed easily, as I have experience with wiring. It's high quality, and well made. I did not use the provided clamps that came with the wiring kit. I've found that splicing and soldering the connections with heat shrink tubing for protection is the best method.



by:

needed this to splice into an existing harness setup. works great. no problems



by:
2004 Pontiac Grand Prix

Hitch delivered quickly. The packaging is excellent. The condition of the hitch is new. The fixing kit, bolts and nuts correspond to the hitch. The video on the site was of great help in installing the hitch. I would like to have a video on the site how to connect the wires, but it's not difficult for an electrician. Problems with the installation of hitches on the car did not arise.


Comments
This Curt 4 pole part C58044 is a hardwire installation. I have attached a video of the hardwire installation for part # 18252 on a 2003 Pontiac Grand Prix. It is a different part number but the same installation. Although, I do recommend part # 56076 custom fit plug and play wiring harness for this vehicle. The plug and play option is a much easier installation.

1987 Jeep Wrangler

This is a standard flat connector for attaching to a trailer. I don't have it installed yet, but it looks like it will work perfectly. The cable is long enough to connect to both rear lights.


Comments
I finally got it installed. My 87 Jeep has had the wiring modified several times in its life so nothing was as it was supposed to be. I finally got all of the previous mistakes unwired, returned it to normal and then added the connection for the trailer. It was easy to install and worked perfectly. I like it and use it all the time.
Ken L - 10/24/2014

by:

This attached very easily to my tail light wires. When not towing, I just shut it up in my trunk, and when I need to pull, I open the trunk and pull them out. I was very skeptical when I got the kit and saw the instructions, but it worked!



by:
2002 Dodge Neon

Looked like I would need more "stuff" to hook up my wiring harness.
However with the help of on line installation instructions.
Mission accomplished.



by:
2001 Ford F-250 and F-350 Super Duty

I have ordered many times through etrailer.com and have never been disappointed. Great service and ever good products. I wish you were in my home town.



by:

I have bought several items from etrailer for several years and I have never been disappointed, mislead, or had to return any of them. I have always found them to have several selections, thorough descriptions, competitive prices, and reasonable shipping charges. I live in a small town about an hours drive from any place adequately equipped for trailer needs. Internet shopping has solved this problem for me. Thank you etrailer.



by:

Perfect for the application and reasonable price. I believe etrailer.com has spent some time considering which wiring kit is best for each vehicle.



by:

I replaced the old wiring harness with this new one. Looks like a very good product.



by:

Dealing with etrailer has been nothing but a joy to do business with. They have a great selection and very reasonably priced. Fast service and delivery. I wouln't hesitate to do business with them again. Looking at their products is like being a kid in a Candy Store.....lol. Their products are first rate quality.



by:

Simple wiring to solve simple issue. Works well



by:

Great product and at a great price, "etrailer" has now become my number 1 stop shop for all my trailer needs now. Due to speed and unbeatable price.



by:
2012 Ford F-250 and F-350 Super Duty

Description of product should in bold letters describe that this is not for the trailer but instead for the vehicle. Product is of no use to me.


Comments
Thanks for posting that. I was wondering the same thing. I need the other end, for the trailer to tow with my truck.
-- comment by: Dan A - 08/28/2013

by:
1991 Ford Van

Product worked okay, but the connectors didn't. They would not close and tap the main wires. I had to splice the wires in directly. Otherwise, It works.



by:

Easy install. Performs exactly as advertised. You will have to buy a special electrical kit to be able to hook up trailer lights.



by:

Great product, superfast shipping....



by:

I received the order in a timely manor and installation was a breeze.
I am very happy with the product and service.

Extant service and products

Ask the Experts about this CURT Trailer Wiring



  • Function Carried on Each Wire of 4-Pole Trailer Harness
    A 4-pole trailer wiring harness like # C58044 uses the brown wire to carry the running light signal for both sides of the trailer. The green wire carries right turn and brake signals and the yellow wire carries left turn and brake signals. The white wire is ground. You can see the arrangement for many popular types of trailer wiring by referring to the linked article.

  • Connecting a Hitch Light to 4-Way on a 2015 Ford F-150 So it Doesn't Deactivate Blind Spot Detector
    The easiest way to connect your hitch light to your 2015 Ford F-150 without it deactivating the Blind Spot Detector would be to install an aftermarket 4-Pole Connector. All you need to do is use the Curt 4-Pole Trailer Connector, part # C58044, and splice into your F-150's lights directly behind the tail light housing. The wire configuration will be: Yellow - Left turn/brake Green - Right turn/brake Brown - Tail lights White - Ground This should bypass the sensors for your Blind Spot...

  • Will 4-Way of Curt Wiring Harness # C58044 Connect to 4-Way of Trailer with 5 Wires
    The 5-wires that are ran to your 4-way means that you have a wishbone 4-way. That means that the running light circuit has two wires ran for each side of the trailer. The Curt 4-way part # C58044 would work well with this. The running light circuit of this kit uses only one wire but will work fine attached a 4-way that has these circuits split out for both sides.

  • What Wire Should Be Used for the Running Light Circuit of a 2006 Buick Lacrosse for Trailer Wiring
    It sounds like you are trying to connect the running light circuit wire of the Curt Vehicle Wiring Harness # C58044 to your 2006 Buick LaCrosse. It would not matter which of the tail light wires you use for this installation. Both wires carry the same circuit.

  • What is the Wire Gauge for Curt Vehicle Wiring Harness with 4-Pole Flat Trailer Connector 58044
    I spoke with my contact at Curt and he said that on wiring harness # C58044 the wires are all 14 gauge. So if you wanted to use different connectors other than the quick splice connectors that come with it, get some for 14 gauge wires.

    After viewing the photos that you sent me, I have a solution to your problem. It looks like the weather shielding around the 4-flat on the trailer was manufactured different then the standard 4-flat. I recommend cutting the old plug on the trailer of and wiring in Curt Wiring Harness with 4-Pole Flat Trailer Connector, # C58044. The Curt end is designed to fit the plug that is on your Ford. You could also try to trim back the weather shielding on the trailers plug to fit the one on your...

    We do not have a 14 gauge trailer wiring harness for your 2008 Toyota FJ Cruiser.

I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118405. I've attached a video of this installation for you.

  • Trailer Wiring Harness for 2017 Cadillac XT5 Without Factory Towing Package
    From what I've been able to determine from my research, all of the 2017 Cadillac XT5 have the plug that is used to connect a trailer wiring harness, so the Tekonsha # 118720 should work for you. If for some reason the plug has been removed, you would need to hard-wire in a harness like the Curt # C58044, but this is extremely unlikely.

  • Can I Tow Two Trailers?
    There are several things to consider when it comes to double towing. First, make sure it is legal in the areas you will be driving. In the west and midwest it is gererally allowed. Most states on the eastern seaboard do not allow it. Even if it is allowed, there may be certain requirements and restrictions state to state. Next, the second trailer will need to be lightweight so as not to require brakes. Generally, if a trailer has brakes you should be using them. Next, you will need...

  • Recommended Trailer Hitch and Wiring for a 5th Wheel Trailer
    The best trailer hitch we offer for a 5th wheel trailer is the Adjustable Width Trailer Hitch Receiver part # 13703 because it's very adjustable and rather easy to install. I have attached a sample install video for you for reference. In order to control the lights, you'll also need the Curt Vehicle Wiring Harness part # C58044.

  • Recommended Trailer Wiring Harness For A 2014 Ford F-150 XL Without Factory Towing Package
    As your 2014 Ford F-150 XL did not include the factory towing package, you will need to use a hardwire kit, like the Curt # C58044. There will not be a T style connector available, unfortunately. The Curt harness # C58044 will include quick splice connectors to make the wiring a lot easier though, and you will not actually need to cut any of the wires to get it installed.

    The Curt # C56175 is a trailer wiring harness that includes a powered converter that is used to handle the additional strain that can occur when powering trailer lights. The # C56175 is the confirmed fit trailer lighting harness for the 1998 Volkswagen Jetta. When a vehicle is connected to a trailer and the car is not specifically set-up for trailer towing from the factory, the powered convert will make sure that there will be enough power sent to the trailer to fully illuminate the trailer...

  • 4-Way Wiring Harness Recommendation for a 2004 Ford Expedition
    If your 2004 Ford Expedition has a factory 7-way installed on it the Curt Harness # C55384 that you referenced would work on your vehicle and would provide it with a 4-way. If you don't have a factory 7-way you would instead need the Curt harness # C58044.

  • Which 4-Way Wiring Harness Fits My 2004 Ford Expedition
    The Curt T-Connector Wiring Harness # C55384 is what provides your 2004 Ford Expedition with a 4-way connector by plugging directly into the 7-way harness that is included with the factory tow package. If you only have a 4-way that is hard wired into the Expedition then I recommend cutting off the existing defective plug and hardwiring a new one with the Curt Wiring Harness # C58044.

    There are wiring harnesses that are designed for your 2019 Jeep Wrangler JL Rubicon, and I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56407, which is a confirmed fit for your '19 Jeep without a factory tow package. This harness does in fact plug in to points in your Jeep's rear cargo area, though it does require you to run a hot lead to your battery. This allows the unit to power the converter which protects your wiring, and it is something...

  • Troubleshooting Trailer Wiring Stop/Turn Circuit Not Functioning
    First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue. Make sure that the trailer side connector are clean...

  • Trailer Wiring Harness for a 1989 Jeep Wrangler (YJ)
    If you bought wiring harness # 118356 then that would be the problem. This harness does not fit a 1989 Jeep Wrangler/YJ. The only trailer wiring harnesses we have listed for the YJ are hardwire harnesses, # 18252 or # C58044. If you bought a different harness let me know what it is and I can determine what it fits since there are no T-connectors for your YJ.

  • 4-Way Trailer Wiring Connector Recommendation for a 2000 Chevy Silverado
    To install a 4-way on your 2000 Chevy Silverado you would want the part # 119147KIT and not the part # C58044 that you referenced. The taillight configuration of your vehicle would not allow the installation of the C58044 because you have separate turn signals from brake lights and this harness requires that they be combined. The part # 119147KIT has a convert box that converts the signal.

I recommend using a circuit tester like part # 40376 and check each pin for function. You want to make sure the pin connected to the yellow wire shows current for your left turn and brakes, green is for right turn and brakes, brown is for the tail lights, and the white wire is the ground which should be secured to a clean, bare metal surface.
