Lorenzo,

What is the color of this extra sporto wire?

Existing wiring harness has three wires into the engine bay for oil: one for temp, one for pressure, and one for oil level.

There is another wire, buried in the harness, that was used for the Sporto oil temp switch (located at the top of the bell housing, on the starter's side of the engine compartment seal) that might be used for an oil pressure 'idiot light' if you desire.

I just did this exchange on my '69 912...
