I bought the switch to replace. I will work on in on Saturday, The switch is only one piece, right? Anything I should also be buying before I try to fix it?

if it is a gauge then you have 2 sensors, one is a switch for the red light and the other is a sender for the gauge sweep.

To test them, have the ignition on then unplug the lead and connect it to ground, the lead for the light should cause the light to come on, the lead for the gauge should sweep the needle to max.

The switch does not affect the sweep of the gauge and vise-versa.

Where is the sensor for the gauge sweep? I need to see which one I need?

they both will be in the oil filter housing, there are a few variations but that's where they normally are
Just to get an idea the switch looks like

And the sender looks like

And if you need either of those parts Autoricambi can supply them to you

The red battery light has nothing to do with these switches, right?
