Mazda Repair: where is OBD connectore located, mazda miata, system checker

Question
Hello, I have a 1992 Mazda Miata, where is the OBD connector located ??

Answer
1992 Miata does not have an OBD2 connector and OBD2 system can not communicate with the ECU.  The systems diagnostics plug center is on the driver's fender apron under the hood, black box marked "diagnostics".  An OBD1 system checker is required.
