Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the rear scuff panel to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


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.


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.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


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.

Not many problems with the wiring harness, other than the wires come popping out of the harness since there is a slit groove over the sheaf. A simple zip tie does the job.

  • Do the Trailer Hitches for a 2013 Lexus IS 250 Fit a 2014 Lexus IS 250
    The trailer hitches are not the same between a 2013 and 2014 Lexus IS 250. As you have indicated the 2013 IS 250 sedan uses hitch # C11372. The 2014 uses hitch # C11389. The side brackets are slightly different on the C11389. There is a little cutout on the backs of them so that they can fit on the 2014 IS 250. So in other words the hitches are not interchangeable. But the wiring harness # C56142 will fit both 2013 and 2014 models. The recommended ball mount for each is # C45521 and you...

  • Trailer Hitch for a 2012 Lexus IS 250C Convertible
    For the 2012 Lexus IS 250C convertible we do have a trailer hitch that will fit but # C11372 that you referenced will not fit. The hitch that will fit is # C11047. I have included a link to the installation details for you. If you plan on doing some towing, first consult the owners manual to make sure the vehicle can tow and for its towing capacity. For a ball mount use # C45522 and pin and clip # PC2. For a ball use # 19256 for a 1-7/8 inch or # 19258 for a 2 inch. And for trailer wiring...

  • Parts Needed for Hitch and Cargo Carrier Installation for 2014 Lexus IS 250
    You will not need any additional parts to install the Draw-Tite Class I Trailer Hitch, # 24923. If there is ever the chance you would want to pull a small trailer you'll need to add a wiring harness # C56142 which will easily plug into your existing wiring system behind the tail lights. Since you're also looking for a cargo carrier, the 47 X 19 Curt # C18110 . Since the only hitches available for your vehicle are Class I you're going to be limited to 200-lbs tongue weight and carriers...

  • New Trailer LED Tail Lights Do Not Light Up with Running lights on 2011 Lexus IS 250
    It sounds like there could be a ground problem. A weak ground could cause this issue. Different vehicles also have different power capabilities so testing with another vehicle does not always indicate where the problem is. What you will want to do is test the vehicle without the trailer connected. You are going to need a meter to test the voltage on the trailer wiring harness on your Lexus. If you need a meter we have # PT89ZR. First, test the running light wire going into the converter...

  • Ground Clearance for a Hitch on a 2014 Lexus IS250
    Yeah it sits pretty low. When the Curt Trailer Hitch item # C11389 is installed on a 2014 Lexus IS250 the bottom of the receiver sits only 6" off the ground. The Curt Trailer Hitch item # C11389 is a class I hitch with a 1-1/4" receiver. It has a 2,000 lbs towing capacity and a 200 lbs maximum tongue weight. I have linked an installation video below to help you get it set up. If you are planning on towing you will also need a wiring harness item # C56142 and the Draw-Tite Drawbar item...

  • Fit of Curt 11389 Class 1 Trailer Hitch on 2014 Lexus IS250 F Sport
    The Curt # C11389 is a fit for all sedan models of the 2014 Lexus IS250, including the F-Sport. If you'll be using the hitch for light duty towing, you'll also need a trailer wiring harness like # C56142, a ball mount and hitch pin like # C45521 and # PC2 and a trailer ball like # A-80 for a 1-7/8 or # A-82 for a 2 inch ball. You can see the parts mentioned above by using the provided links.

  • Recommended Trailer Hitch for 2014 Lexus IS 250
    I spoke with my contact at Curt and he said the Curt trailer hitch # C11389, which you reference, is a confirmed fit for your 2014 Lexus IS 250. The hitch will not interfere with the factory exhaust, however the exhaust must be temporarily lowered for installation. In order to know if the hitch will interfere with your aftermarket exhaust, I will need to know what kind of aftermarket exhaust you have. I have attached a photo of Curt trailer hitch # C11389 installed on a 2014 Lexus IS 250...

  • Recommended Trailer Hitch Receiver for 2015 Lexus IS 250 for a Bike Rack and Light Trailer
    I recommend the Draw-Tite trailer hitch receiver, part # 24923, for your 2015 Lexus IS 250. It's confirmed to fit both the sedan or convertible models. The hitch is a Class I, 1-1/4 inch receiver so you need to make sure the bike rack you use fits the Class I. The bike rack I recommend is the very popular Thule T2 Pro XTR, part # TH23JV. The T2 is a platfrom rack that carries up to 2 bikes at 50 pounds each. it can be folded up out of the way when you're not using it as well as tilted...

  • Hitch Recommendation for a 2014 Lexus IS 250
    Yes, the Draw Tite Hitch part # 24923 that you referenced has been confirmed to fit your Lexus IS 250. To complete your towing setup you may also be interested in the Ball Mount # 3594, Hitch Balls # 19256 and # 19258 and trailer wiring # C56142.
