4-Way Trailer Connector Installation

Because the color/function of the wires on this connector may not match the color/function of those on your vehicle, be sure to use a tester (sold separately) to double check the function of each wire on your vehicle's tail light wiring harness before installing this connector. Once you've figured out the functions of your vehicle's wiring, use the included quick-splice connectors to connect the corresponding wires on the trailer connector. Quick-splices, or "wire taps," offer a quick way to make connections without you having to strip and twist wires. Just place the wires in it and snap the cover down.


The number 1 reason trailer wiring comes up faulty is a bad ground, so make sure your ground wire has a solid and clean connection to metal. To make this connection, you'll need a self-tapping screw and a ring terminal (sold separately).


Wiring Configuration

Wire Color Wire Function
Green Right turn and brake light
Brown Tail lights and running lights

Yellow Left turn and brake light


Quick Tips:

We install a lot of wiring harness around here, so we thought we'd share a few tips we've picked up over the years:

  • Butt connectors - especially heat-shrink ones - provide the most secure, longest-lasting connection, so we'd recommend you grab a few and swap them out for the quick-splices in this kit.
  • Use a circuit tester on the plug terminals once the harness is installed to make sure everything's working. There's nothing worse than figuring out that you have a bad ground or a faulty connection right before you're about to hit the road.
  • Be sure to put a little bit of dielectric grease on the 4-way plug to protect the terminals from dirt, grime, and corrosion.

Oh my goodness! Customer Service will be in touch as soon as possible.

While it worked well, I threw out the supplied connectors and used more weather proof versions. But the wiring was long enough and I have had no issues with it.

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

Great, no issues. As good as the day I put it on.

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.

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.

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.

Ken L.

10/24/2014

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.

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.

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.



by:

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

Harness is still like brand new. The cover cap keeps the contacts nice and clean when not in use. Would buy again anytime.



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:

Just what I needed. Splice taps went right in the trash though. Crimp caps are reliable.



by:

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



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:

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'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:

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:
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:
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.

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.

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:

that what I needed to complete the job



by:

Thanks great job



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:
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.

Dan A.

8/28/2013

Thanks for posting that. I was wondering the same thing. I need the other end, for the trailer to tow with my truck.



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.

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

  • 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.

  • 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...

  • 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.

  • 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.

  • 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.

    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...

  • Recommended 4-Way Flat Connector For 2008 Toyota FJ Cruiser
    We do not have a 14 gauge trailer wiring harness for your 2008 Toyota FJ Cruiser. We do have 3 16 gauge options that are confirmed as a custom fit for your vehicle, and that gauge is the industry standard for most trailer connectors. 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. If you want a 14 gauge wire, you can use the Curt Vehicle Wiring Harness with 4-Pole Flat Trailer Connector...

  • 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.

  • 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.

  • 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...

  • 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.

  • Recommendation For A Wiring Harness That Is 60 Inches Long
    Yes, I have what you are looking for! The Curt Vehicle Wiring Harness with 4-Pole Flat Connector, Item # C58044, is very similar to the Hopkins Wiring Harness, Item # HM48035, that you referenced. It is a universal wiring harness kit with all the necessary hardware needed for installation that is 60 inches long. I have attached a video for you to check out.

  • Tail Light Converter to Combine Separate Stop and Turn Lights for Trailer
    In most trailer wiring the stop and turn light signals are combined into one circuit for each side of the trailer. 4-pole wiring uses a yellow wire for the combined left-hand stop/turn signal and a green wire for the right side. 7-way wiring also combines these light functions. You can refer to the linked article on trailer wiring. If you are looking to connect a motorcycle's separate stop and turn lights to a trailer whose lighting is combined you can use Roadmaster part # RM-732. This...

    I do have a potential solution for you, but the Hopkins Wiring Harness # HM11141215 will not fit your S-10 Blazer. This will fit S-10 pickup models only. For your S-10 Blazer I do not have any plug and play options available. Curt does make a universal splice-in kit # C58044 that we have confirmed to fit your vehicle. You would simply use the included quick splice connectors to tie in to the vehicles brake and turn signal wires. I have linked an install video below for you to take a look at.

    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...
