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 Scion xD (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 56136 is designed for the Scion XD. The installation accesses the vehicle's taillight wiring harness located behind the rear access panel.
The Curt 56136 T-Connector is a trailer wiring harness that integrates with your Scion XD's taillight wiring. It includes a converter box and a 4-flat connector that can be routed out when in use and stored away when not needed.
The Curt 56136 includes a T-Connector harness with yellow and green wire ends, a black converter box, double-sided tape, a white ground wire with eyelet and screw, and a 4-flat connector.
You will need basic hand tools. If a suitable grounding point does not exist on the vehicle frame, you will also need a drill with a 3/32" bit to create one.
Open the hatch and remove the rear cargo area floor cover, the foam storage tray underneath it, and the rear scuff panel (held by two plastic fasteners). The taillight wiring harness is then accessible behind the rear access panel.
Locate the vehicle's taillight wiring harness behind the rear access panel on the driver's side. Separate the connectors carefully without damaging the locking tabs. Insert the T-Connector end with the yellow wire between the separated connectors, ensuring the connectors are fully inserted with locking tabs in place. Repeat on the passenger side using the T-Connector end with the green wire.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no suitable point exists, drill a 3/32" hole and secure the white ground wire using the eyelet and screw provided.
Locate a flat spot on the vehicle frame and adhere the black converter box using the double-sided tape provided.
Route the 4-flat connector out from under the rear trim panel to the center of the vehicle when in use. When not in use, roll it up and store it in an out-of-the-way location.
Drilling is required only if a suitable grounding point does not already exist on the vehicle frame. If needed, drill a 3/32" hole for the ground wire. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
