If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Lexus HS250h and CT200h (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Yes, Curt part number 56099 is designed for the Lexus HS 250H. The T-connector harness and converter box are specifically engineered for this vehicle model.
You must remove the following items from the trunk: cargo net, trunk floor covering, jack storage tray, rear scuff panel (by removing plastic fasteners and pulling up), and plastic fasteners holding the felt trunk liner in place on both sides. You will also need to access the vehicle's taillight wiring harness located behind the felt trunk liner.
You will need a 10 mm socket to remove and reconnect the battery terminal nuts. The installation kit includes double-sided tape for securing the converter box and cable ties for securing loose wires. No other tools are mentioned as required.
The battery is located on the passenger side behind the back seat in the trunk. You will access it after routing the black power wire behind the felt trunk liner.
Using a 10 mm socket, remove the nut on both battery terminals. Remove the negative (−) battery cable. Connect the black power wire terminal ring to the positive (+) battery terminal. Reconnect the negative (−) battery cable. Then insert the 10 AMP fuse into the inline fuse holder.
The installation requires a 10 AMP fuse, which must be inserted into the inline fuse holder after connecting the black power wire to the positive battery terminal.
Locate the vehicle's taillight wiring harness behind the felt trunk liner. The harness will have connectors similar to those on the T-connector harness. Starting on the passenger side, carefully separate the connectors without damaging the locking tabs. Insert the T-connector end with the green wire between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the yellow wire T-connector end.
Adhere the black converter box in the spare tire compartment in an out-of-the-way location using the double-sided tape provided with the kit.
Secure any loose wires and loose parts of the T-connector using the cable ties provided in the installation kit. This should be done during step 4 and again after re-installing removed components in step 6.
Before drilling, verify that miscellaneous items hidden behind or under any surface are not present. This will avoid damage to hidden components and prevent personal injury.
