Take off the electrical harness from the heater element and carefully remove the heater element from the pad . Send the heater element wire through the hole in the pad. Make sure the heater element electrical harness goes through the hole in the pad, then stick the heater element - adhesive side down - onto the pad. Connect the electrical harness to the heater again, install the seat cushion cover and pad, and put the seat assembly into the car.
