To prevent wrinkles when installing a seat-back cover, make sure the material is stretched evenly over the pad before securing the upholstery rings, the hooks, and the hook strips.
Before installing the seat-back cover, make sure airbag wires (A, B) are installed to the reinforcing cloths (C) correctly.
Replace any upholstery rings you removed with new ones (D). Install them with commercially available upholstery ring pliers (E).
Reinstall airbag wire A, and B securely.
Use only original Honda replacement seat-back covers.
Make sure the side airbag harness and the OPDS unit harness (some passenger's seat) are routed properly.
