  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the passenger's-side tail light. You will have to remove the tail light assembly to access this harness.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56046 Review

Today we're going to be taking a look at part number C56046. This is the Curt T-Connector Vehicle Wiring Harness with your 4-Pole Flat Trailer Connector. This is going to fit certain years and models of the Chevrolet Impala. It's going to provide your 4-way flat trailer connector at the back of vehicle to power your trailer's signal lights. This is compatible with 5-pole, 6-pole, and 7-pole adapters. Adapters are sold separately. It's going to come with a dust cap for the 4-way flat connector.

That way you can cover up those connection points when the plug is not being used. The main benefit of this system is not only the 4-way flat connector, but it's designed to connect quickly and easily. You don't have to cut or splice any wires. All you have to do is locate the connection points behind the passenger side tail light and plug in your T-connector. This is vehicle specific.

This is designed to match up perfectly with the connectors on your vehicle. You are going to plug them. They're going to snap-lock together for a nice, tight, secure fit. Once you have that connected, you'll need to make your ground connection. It's going to be a white wire with a ring terminal attached to it. You can make that ground connection to a nice, clean metal surface with the included self-tapping screw that's provided in the hardware kit.

Then you can go ahead and secure your excess wires with the included zip ties. Then once your installation is complete, the 4-way connector is going to be stowed in an out-of-the-way location within your rear cargo area when it's not being used. That's going to come with your detailed instructions. These are going to walk you through the installation process step-by-step. We recommend that you use a small amount of dielectric grease on all your electrical connections like the plugs on the vehicle and the 4-pole connector itself. That's going to help prevent corrosion.

If you don't have some of that, you can find that here at etrailer.com. It is sold separately. That's going to do it for today's look at part number C56046.

Chevrolet

At first was confused since I thought it would connect to each brake light. But Chevy ran everything to one tail light then over to the other so just one connection. The wire is heavy enough it can take me shutting the trunk over it. I have used this now for close to a year and used it a lot. So it is a good solid product




by:

Quality built trailer hitch Fit perfectly to car frame mounting locations. Installation videos are accurate and VERY helpful.
The wiring harness for trailer lights is truly a plug and play with VERY easy installation and the length of connecting harness is long enough to reach any trailer hookup you may have.

2015 Chevrolet Impala

I searched for quite some time for a custom fit wiring harness for my 2015 Impala Limited which is the old body style starting, I believe, in 2006. Once Chevrolet came out with a new body style in, I believe, 2014 for the name Impala, the old style became the Impala Limited. Some manufacturers don't even recognize the Impala Limited at all. The Curt 56046 custom vehicle to trailer wiring harness with the application for only the Impala 06 through 2013 is also a custom plug in fit for the newer Impala Limited. At lease the 2014 and the 2015. You find the plug behind the passenger side tail light, plug in the T-connector, route the wiring through an existing hole to keep it in the trunk, or run it directly to the hitch under the trunk. I'm extremely pleased with the product.

Good product.

After watching the video I installed the wiring harness in no time. Extremely easy. Free shipping and recieved my package in three days.
Also installed the C12252 trailer hitch. Not much to it. 6 bolts and it's on. My only regret is not purchasing the drawbar too. I will now end up ordering one from etrailer and paying shipping.

Exactly what I wanted for a good price, delivered quickly and only took 5 minutes to install and it works great.

  • Why Does Hopkins Trailer Wiring Harness Install Differently than Others for a 2011 Chevy Impala
    The Curt wiring harness # C56046 as well as the Tekonsha harness # 118417 both plug into just one side of the 2011 Chevy Impala. The main tail light wiring harness that runs from the front to the back of the vehicle is located on that side so it is possible to just tap into that harness. The Hopkins harness # HM11141595 is just a different design. The connectors for the passengers side do not have the wiring in them to get the signals for the left side of the vehicle like the other harnesses...

  • Recommended Trailer Wiring Harness for 2015 Chevy Impala Limited
    I'm glad to hear your trailer hitch receiver installation went well. For your 2015 Chevy Impala Limited, I recommend the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 which has a max amperage of 5 amps on stop/turn lights and 7.5 amps on tail lights. This is a confirmed fit for your vehicle and will protect your factory wiring. The Hopkins # HM48925 will only put out a max amperage of 2.1 per circuit so that won't help. There are many that could work,...
