ata,
That is your oil sending unit. The temp sensor/sending unit is up higher (located in the head) and further back.
Bandit you probably found it . It is located on the side of the head to the right of the fuel filter where the fuel line hoses start to curve downward. Easy to see from underneath the left front tire but hard to reach. If you stand on your tire and look down at fuel lines/firewall you can see the connector (not to bad of a reach).
