Like most questions of this type, you will find your answers in the Factory Service Manual, or FSM.
The Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars.
Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.
These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.
That said, you will find the ECT (Engine Coolant Temp) sensor on the back of the water pump housing under the thermostat neck. There will be an injector style connector plugged into it. Test the senser as per instructions in the FSM prior to replacement.
