Does anyone know off hand what threads the FSDE uses for the oil pressure switch? I'm going to be adding an oil pressure gauge and will likely need to add a T fitting to the back of the block, so I can run both the gauge and the factory switch. Unless there's another oil passage somewhere that's a little easier to access.
Additionally, those of you that have aftermarket gauges, what power source did you splice into for gauge illumination?
