NOTE:
  • Use fender covers to avoid damaging painted surfaces.
  • To avoid damaging the wiring and terminals, unplug the wiring connectors carefully while holding the connector portion.
  • Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact any other wiring or hoses, or interfere with any other parts.
