Default Coolant temperature sensor for a 1991 XJ

My temperature gauge is no longer working, so I suspect it is the coolant temperature sensor. But I see two on my Jeep. One is in the thermostat housing, and one looks like it is located on the intake manifold near the firewall on the driver's side. I do not have an electric cooling fan on this Jeep - looked like it never came with one, this is a Jeep that was also sold with no A/C. Which sensor do I need to replace to get the gauge working? Thanks in advance.

The one on the head near the firewall.

Found it. I kept looking for the type like on the thermostat housing with two wires and the plug in type connector, not the one that looks like a threaded rod.
