Oiltemp sensor B16A1

Whats up guys,

I have a CRX SiR ( B16a1)
I bought a used Oiltemp meter ( autometer) but I didn't get the sensor with it.
I can get another one buy where do I put that sensor in??
the sensor that I can buy is to small it doesn't fit in my oil pan drain hole

Where does this thing go into?

you will have to drill a new hole in your oil pan and mount the sensor, make sure you do this right, or you'll leak oil forever.
