Where to hook up a coolant temperature sensor on a 96?

I am looking for a place to hook the sensor for an aftermarket temperature sensor gauge, the stock idiot light is plugged into the T-Stat housing, is there any other openings on the head or intake that I can not see where I could add this sensor at? thanks!

There should be a 1/8" NPT hole at the rear of the head, drivers side. It will or should have the temp gage sender in it.

EDIT: there is also a plug in the side of the engine block on the drivers side near the motor mount, 3/8" NPT I think

If you can't get the block plug out try an in-line radiator hose adapter:

I found the 1 3/16 one fit the upper radiator hose. Depending on the size of the temp probe you may need to drill the hole larger (believe it's 1/8 npt?) & tap.

I've always seen them in the heater hose
