3. Place the seat heater elements underneath the seat fabric, following the instructions provided in the kit. Ensure even placement and secure the elements firmly.
4. Connect the wiring of the seat heater elements to the vehicle's electrical system, following the instructions of the kit. Note: it may require some wiring knowledge or professional assistance if you're not comfortable working with automotive electrical systems.
