Note. Use fender covers to avoid damaging painted surfaces. To avoid damaging the wire 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 other wiring or hoses, or interfere with other parts.
