I believe in terms of a specific NB8A manual the only option is the Mazda factory workshop manual of which I believe there's a separate wiring diagram supplement (there was with the NA6).
In terms of NA8 manuals, apart from the Mazda factory workshop manual, there's Rod's Enthusiast's Shop Manual & the Haynes Repair Manual (1990-1997), the latter of which contains some basic wiring diagrams. Rod's doesn't contain a set of wiring diagrams, & notes they thought it was pointless given the global export, & therefore wiring variations of the MX5. Rod's also notes the approach they take in their electrical section is to provide info to troubleshoot. Apart from that Rod's also do an NA6 manual.
