This manual explains the functions and uses of that mysterious black box located near the air filter-the diagnostic connector. The procedures apply equally to most models of Mazda MX5, Miata, and Eunos Roadster 1989>2000. The purpose of this manual is to enable the home mechanic or independent garage to access the self diagnostic facilities of the MX-5 which are normally only available to Mazda dealers through the use of their factory provided service tools.
Includes a free DIY led probe to get you started!
