ignition off , simply disconnect wires 7 or 8mm nuts and unscrew plugs they might be tight , if so work forwards and backwards using reasonable force and possibly spray with wd 40 or similar fit new plugs and connect wires, simple as that. depending on access you may need a socket or spanner to do this and be carefull not to drop nuts they can be a bit fiddley
