Features to know about

Installs Fast with Plug-In Design: No Cutting or Splicing

Hooking up trailer wiring doesn’t have to be complicated. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs straight into the vehicle’s wiring, so there’s no need to cut or splice factory wires. The plug-in design keeps things simple and helps you get your trailer lights working in no time.

Protects Vehicle Circuits: Powered Converter with Direct 12V Connection

This harness includes a powered converter that connects directly to the vehicle battery. That built-in power source keeps the trailer lights from overloading the vehicle’s taillight circuits. It draws power only when the lighting functions are active, giving you reliable performance without draining the battery.

Delivers Standard Trailer Lighting: 4-Flat Connector Output

The 4-flat connector provides the running, turn, and brake light signals your trailer needs for safe travel. It’s the most common trailer connection out there, making it easy to hook up to most small and mid-size trailers without extra adapters.

Built for Long-Term Use: Weather-Protected Connections

When it’s not in use, keep the 4-way end covered to protect it from dirt and corrosion. For a solid electrical connection every time, apply dielectric grease at plug points and make sure the ground is attached to clean, bare metal. These small steps help the Curt T-Connector stay dependable whether you tow often or just occasionally.

Handles Trailer Lighting Loads Reliably: Rated for 5.6 Amps on Running Light Circuit

The harness is rated to deliver 5.6 amps on the running light circuit, giving it enough capacity for typical trailer marker and clearance lights. Follow proper installation practices—especially grounding and fuse protection—and you’ll have stable lighting that performs trip after trip.

This product is exactly what I was looking for. No cutting and splicing, easy and clean install. What else is there to say? I highly recommend this harness for your trailer plug need.



by:

The wiring harness works great and was easy to install.



by:

After buying four of these hitches in the last four years, what more could I say. I think that would have been recoginized by your company and been given a small discount for buying from you so frequently. Enough said about that. Frequent customer.



by:

Thank you for shipping so fast. I already put the hitch on. and wiring is also installed. Good directions and great looking. Thank you again.



by:

I bought the C56145 custom wiring kit it is a must have item. The dealer wanted $300 for the wiring kit + $ to install. I save a lot by doing it myself and thank "etrailer.com" for handling a fine product.
Respectfully,
Larry Royal



by:

I was able to do a quick and professional looking wiring installation with your kit. I would recommend it to others.



by:

Everything was great with only one exception. The instruction state to be careful removing the wire connectors from the taillight. With no instructions on how to remove them. 1. Push the red sliding saftey clip back.
2. push down on the black clip and gently pull the socket apart using a side to side motion. Henry



by:

Perfect fit connectors and very convenient to not need to splice into factory wires.

  • Will Trailer Hitch for 2012 Chrysler 300 Fit SRT8
    Hey Jim, welcome back! The Curt hitches fit the 300C and 300S. The Draw-Tite Max-Frame Trailer Hitch Receiver # 76145 is confirmed to fit all models of the 300, including your SRT8. What will you be using the hitch for?

  • Modifications Needed for 2014 Chrysler 300S To Install Class II Trailer Hitch
    According to the installation instructions for the Draw-Tite Class II trailer hitch, part # 36548, there is no cutting or modification if the bumper fascia required (see linked instructions). However, on 2011 and newer vehicles, there's a plastic appearance panel under the vehicle that would need to be removed and left off the vehicle. There is a trailer wiring harness available, part # C56145. If you'll be towing with this hitch, you'll need a ball mount like # 36051 but remember to account...

  • Trailer Wiring Harness Recommendation for a 2008 Chrysler 300
    You are going to have to install a wiring harness with a converter box to be able to install a 4-way on your 2008 Chrysler 300. You are correct, because the taillight circuits of your vehicle are separate and the taillights on most trailers are combined a converter box is required. The Curt wiring harness part # C55546 would be the correct harness for your vehicle and would install pretty easily.

  • Power Fuse Blows on T-One Vehicle Wiring Harness # 118544 When Running Lights are Engaged
    The two most likely causes for the blown 12V power fuse that feeds your TowReady T-One Vehicle Wiring Harness # 118544 are a short within the trailer wiring for its running light circuit or excessive current draw from the clearance/marker lights on your trailer. If you happen to have access to either another tow vehicle or trailer you can try substituting one in place of yours to see if the issue remains. This is the easiest way to isolate the fault to either the vehicle or trailer. If...

  • Cargo Carrier And Hitch For 2011 Chrysler 300 To Carry Folding Wheelchair
    If you do not have a hitch on your 2011 Chrysler 300, I recommend a hitch and a cargo carrier. After doing some research on your vehicle I found that the towing weight capacity is 1,000 lbs. that means the maximum tongue weight capacity or total weight a hitch could handle is approximately 100 lbs. I recommend the Draw-Tite Trailer Hitch, part # 36548. This is a Class ll hitch and has a 1-1/4 inch receiver opening. I also recommend a flat hitch-mounted cargo carrier like the Rola Packer...

    For your 2011 Chrysler 300, we offer the Curt T-Connector, # C56145. I have attached an installation video on a 2013 Chrysler 300 for you to check out. While this is a plug and play unit, you will have to run the main power wire up to the vehicle battery. These wiring harnesses require a direct 12v connection to the battery to power the trailer or accessory lights. This is to protect the vehicle's tail light circuits from overloading. I have attached a help article on tips for routing...

  • How to Use Roof Top Tent with 2014 Chrysler 300
    I have a way for you to transport and use a roof top tent, like the Yakima SkyRise HD Tent # Y07436, with your 2014 Chrysler 300 but every roof top tent I've looked at says not to mount and use a tent on a roof rack that uses clips for the door jambs like what we see with this Yakima setup. The 165 lb weight rating is the dynamic rating so the static rating would be higher, but we need to look at a different solution since a clip-style roof rack shouldn't be used for this application.

  • Can a Curt Trailer Wiring Harness for a 2013 Chrysler 300 be Used Often or Infrequently
    You can use the Curt trailer wiring harness # C56145 as much or as little as you want. If you do not use it very often though you will want to make sure that you use dielectric grease between electrical connections (# 11755), and make sure the ground is attached to a clean and corrosion free bare metal surface. Also make sure the cover is placed on the 4-Way end when not in use.

  • Is There Fascia Trimming Required to Install Trailer Hitch on 2014 Chrysler 300
    I checked the install instructions for the Curt hitch part # C13093 that you referenced which is a fit for your 2014 Chrysler 300C and there is no mention of rear fascia trimming or removal so that's not something you would have to worry about. Now for a trailer wiring mounting bracket the part # 18144 would be a great option to use to hold the 4-way connector of the part # C56145 which is a fit for your vehicle as well. This bracket actually attaches to the rear bumper of the vehicle...

    Yes, Curt trailer hitch # C13093 fits all models of the 2014 Chrysler 300 including the base models. If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If the ball mount kit does not have the right rise or drop to tow the trailer level, use...
