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).

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.

Perfect length and wired in with ease, Just wish it had a weather proof cap included. but still very happy

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.



by:

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

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.



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.

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

James

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

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

Paul

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



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:
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:

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:

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

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.

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



by:

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



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:

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:
2011 Volkswagen Golf

Was nice and easy to wire up camper to second trailer for golf cart. Now I pull doubles. LOL



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.

  • Can I Tow Another Trailer with ATVs Behind My Bumper Pulled Trailer
    Most states do allow you to tow a trailer behind a trailer as long as it does not exceed a certain overall length- I believe California has a limit of 65 feet total length of all 3 vehicles. You would need to consult with your State's laws and any other locales that you might be towing in to make sure that this is allowed there. You also may be limited by your trailer's ability to handle additional weight pulling at the back, so you'll want to check with the trailer manufacturer to determine...

  • 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.

    We definitely have what you are looking for. While we do not have a hitch that can attach directly to your bumper of your 2015 Smart fortwo, we do have a hitch-mounted carrier that you can use after the hitch is installed. For the hitch, that is the Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # C11020. Not only does this hitch provide you with 200 pounds of maximum tongue weight capacity and 2,000 pounds of gross towing weight capacity, it also comes with a premium gloss...

  • Recommended Trailer Hitch for Towing for a Coleman Lite 2955RL Trailer Trailer
    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. Instead, I recommend a frame mounted trailer hitch which is much stronger, the Adjustable...

  • Recommended 5th Wheel Rails, Hitch & Wiring Harness for a 2011 Ford F-350
    For your 2011 Ford F-350, I recommend checking out the Curt Custom 5th Wheel Installation Kit for Ford - Carbide Finish # C16424-204. This is an above-bed rail system that will easily install to your 2011 Ford F-350 and will provide a mounting point for a 5th wheel hitch like the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider # C16541. Also. these rails will work with Curt, Draw-Tite, Hidden Hitch, Husky, Valley, & Reese 5th Wheel hitches. This hitch has a maximum towing capacity of 20,000-lbs,...

  • 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...

First you will install a 4 pin connector part # C58044. This will simply splice in using the included quick splice connectors. Next you will need to install the universal 7 way install kit # ETBC7.

  • 6-Way to 4-Way Adapter Recommendation for RV Flat Towing Vehicle
    To adapt a 6-Way round trailer connector to a 4-Way flat, you will just need an adapter like # 47305B that you have referenced. The turn signals and brake lights on the Winnebago do not matter because the signals at the trailer connector are already converted to have the brake lights and turn signals on combined circuits which is what trailers use. If for some reason you had separate trailer wiring on the RV you would need to make an adapter. You would need an adapter # RM-732 and a part...

A USCAR 7-way socket is a standardized automotive electrical socket that provides a connection point for trailer wiring.

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...

It can bump up to 600 lbs tongue weight and 6,000 lbs max towing when using weight distribution.
