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
White Ground
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.

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.

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.



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

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:

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.



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.

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



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:

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:

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



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:
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:
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.

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



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.

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.

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:

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:

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:

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



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:

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

    The Rampage SuperBrite LED Tailgate Light Bar # RA960134 will install using automotive grade adhesive tape and will plug directly into a 4 way trailer connector.

  • 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...

  • 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.

While there is not a custom fit trailer hitch receiver for your 1998 Blue Bird TC2000 your best option is going to be going with a universal heavy duty trailer hitch like the Draw-Tite # 41990-07 with 7" tall mounting brackets, or the # 41990-16 with 16" tall mounting brackets. These options fit frames between 18-44" wide which should be perfect for the frame on your vehicle. You will need to have a qualified welder weld the hitch to the frame of your TC2000. Both...

    Yes, you can install a trailer hitch on a Coleman Lite 2955RL Trailer Trailer. In order to do this you have a few options. The first is a bumper mount hitch which bolts onto the bumper, the Curt RV Bumper Hitch part # C19101. This is a good option for bike racks or other hitch mounted accessories but isn't great for towing and would likely require bracing of the factory bumper if used in such manor.
