Part number 7705830 is an oil pressure switch.

is that supose to be connected anywhere davren? cause it seems like there is some connector at the end of it but its like there is no wires coming out of it just blank.

According to the wiring diagram, the switch is earthed by it's mounting thread to the engine, and should have a single brown wire from it going to pin 7 of connector A on the engine management ECU.

The switch controls the low oil pressure warning light on the dashboard and should look similar to the one below.
