Alright, here goes...

What you'll see looking at it from the front of the car:


This is what you'll see if you stick your face down there for a better look:


This is with the camera phone all up in there:




The Coolant Temp. Sending Unit should be torqued down to 7ft-lbs. (or tight, but not too tight, with a ratchet as I would do it) and you should use liquid gasket on the threads.

It's not that uncommon for people to mistake the TW Sensor (not switch as I labeled it in one pic) for the Temp. Gauge Sender. Unrelated to your Q but incase someone's wondering, the TW Sensor should be torqued to 13ft-lbs. whereas the Thermoswitch, even though they look alike, should be about 17ft-lbs.

This should apply to all 5th gen ('92-'95) Civics. The pics are from my USDM '92 EX.

Hope that helps.
