Default installing oil pressure/air-fuel ratio

Sup guys, quick question my buddy left to the navy and he left me 2 quages, he left me a oil pressure guage and a air/fuel guage,measuring rich/lean

My question is,
I have no idea how to install these guages, is there any one that can teach me or point me the right direction to installing these guages???

the oil pressure guage has a small hose with some t-spliters and a nut at the end...
the air/fuel guage has 3 wires, 2 im assuming for the light that it go built in and 1 is for taping into something but i dont know why?

Any help will be more then helpfull...

OHH and i forgot to post, its a 99 civic ex

a/f gauge's third wire goes to the white wire of the primary o2 sensor. Other two goes to 12v and ground. But don't trust the narrowband a/f gauge, it's just gonna bounce around be mostly a light show. A wideband is really the only trustworthy a/f gauge.

like flip said, your afr gauge is a narrowband, I wouldn't use it.
This is how i hooked up my oil temp gauge(manual, Auto Meter), it's also the same hole used for the stock oil psi. gauge.

If anything, this picture should show you where to mount it.
