Oil Pressure Sensor threads size

[Tombonombona]

Ok guys, have an oddball question.... I am assuming that the sensor that is at the front and bottom of the engine is an oil pressure sending unit for the ECU, please correct me if I am wrong.
Now on my car I had an aftermarket oil press gauge installed (Defi) and the person that installed it used a couple adaptors to make both sensors work and what has happened is now both sensors are hanging off a long thin stalk of adaptors. What I am wanting to do is to make a remote manifold that I can hard mount to something and connect to the engine via a flexible line.... I just don't know where to find the thread sizes or pitches.

Thank you in advanced.
