Oil pressure switch location?

[14mins]

I am trying to install a oil pressure guage. Is the switch that i am looking for located under the turbo, behind the lower radaitor hose with 3 wires coming out of it? Is there a special tool for removing it. Do i need to do something with the 3 wires to keep the idiot light from coming on? Thanks for the help.
