    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your tail lights. You will access this harness by removing the driver's-side and passenger's-side interior trim panels. Once you've plugged in the T-connector, run the hot lead up to your car battery and connect it to the positive terminal. Then insert the included fuse into the integrated fuse holder.


Once installation is complete, the 4-way connector will be stowed within the battery compartment of your vehicle's rear 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.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

  • Maximum Towing Capacity of 2011 Cadillac CTS with Curt Class I Trailer Hitch Receiver
    I looked at an online copy of the owner's manual for your 2011 Cadillac CTS and it states that your car can tow no more than 1,000 pounds. You should check your owner's manual to verify this. The Curt Trailer Hitch Receiver # C11196 has a maximum towing capacity of 2,000 pounds however this will not increase the capacity of your Cadillac. You are limited by the lowest rated factor which in this case is the car. If you're going to use the hitch to carry anything other than a trailer...

  • Correct Wiring Harness for 2012 Cadillac CTS Coupe
    The T-One Vehicle Wiring Harness # 118466 is designed to work with the 2012 Cadillac CTS Sedan, excluding the V-Series. Since this will not work for your coupe, you will need the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56044 which fits both the sedan and the coupe. This will plug into the connection points behind your tail lights just like the Tekonsha harness would so no cutting or splicing is required. This also includes powered tail light converter...

  • Will Curt Trailer Hitch Fit 2013 Cadillac CTS Luxury Sedan
    Yes, the Curt # C11307 will fit your 2013 Cadillac CTS Luxury Sedan. The hitch features a bolt-on installation and comes with a limited lifetime warranty. If you plan on towing, you can use the # C56044 for wiring. This will give you a 4-way to power your trailer's signal lights. For a ball mount, check out the # 3594 along with the # C40001 for a 1-7/8" or # 19258 for a 2" ball.

  • Parts Needed to Install 7 Way and Brake Controller for 2013 Cadillac CTS
    If you've already got a 4 flat like the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56044 on your 2013 Cadillac CTS then in order to add a 7 way connector you'll want to use the # ETBC7L. The # ETBC7L is designed to work with wireless brake controllers, so I recommend using the Curt Echo # C51180 which is controlled by smartphones running iOS 8.0 or newer, or Android 4.4 or newer. The Echo plugs into the # ETBC7L and accepts the trailer's 7 way plug to...

  • Picture of Curt Trailer Hitch Installed on a Cadillac CTS Coupe
    Curt has a nice picture of trailer hitch # C11196 installed on a Cadillac CTS coupe. I have include it for you here. The hitch receiver and cross tube are visible beneath the rear fascia of the vehicle. If you plan on doing any towing with the hitch then the correct ball mount to use is # C45571 for a 1-7/8 inch ball or # C45572 for a 2 inch ball. For trailer wiring you can use # C56044. I have linked the instructions for the wiring as well. If you are using the hitch for a bike rack...

  • Will Curt Hitch # C11307 Fit 2010 Cadillac CTS Sedan and CTS-V Sedan
    I spoke with my contact at Curt and he told me the Curt Class I Receiver Hitch # C11307 is a fit for both the 2010 Cadillac CTS-V Sedan, and the 2010 Cadillac CTS Sedan. The Curt Hitch includes a pin and clip. If you plan on doing some light duty towing you will need a ball mount like # C11307, a hitch ball like # 19256 (1-7/8 inch diameter) or # 19258 (2 inch diameter). For trailer wiring use Curt Vehicle Wiring Harness, # C56044. I have linked to the hitch's installation instructions...
