Unknown Sensor on Engine Block
Hey guys, I'm cleaning my wire connections on my '96, 4.0 Manual Trans and I came across this little guy on the back right of the engine block, just next to the valve head cover. It looked to me like it was just glued into the engine block with some rubber gasket material, and wiggling it around was very easy to do. I noticed a crack in the sealant and pulled a bit, and the sensor came completely out. Turns out it was actually a styrofoam-like material that it was seated in, like that spray foam sealing/insulation stuff that expands and gets hard when it dries.
My guess is that this is a temperature sensor, but does anyone know for sure? Also, how should it be properly secured? Pics would be fantastic. I get a crank no start with this connection undone, so it seems critical. Thanks for any input.

that's the temp sender, not sensor (which is located in/on the thermostat housing) and I think it's broken that's why it looks so weird. it only controls the dash temperature gauge so you don't have to rush to fix it, but it's still a pretty inexpensive part.
usually looks like this
