NB fuse box wiring diagram? I just finished wire tucking my 2000 miata and everything is working except my rpm tach everything else works and i checked fuses and none are blown. So instead of going through every wire which is like 50 seperate wires i just wanna use a diagram find the wire and see whats wrong and why its not connecting.. In this article, we consider the second-generation Mazda MX-5 Miata (NB), produced from 1998 to 2005. Here you will find fuse box diagrams of Mazda MX-5 Miata 2002, 2003, 2004 and 2005, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout).
