COP Thread
as far as i can see there's only 3 wires into the coils packs on my 00, is there +something i'm missing, i cant seem to find the v+, maybe i should lay off the vodka before attempting wiring
I thought the newer Miata coils don't have tach outputs. The tach signal comes from the ECU or something like that. But I could be mistaken.

http://www.madracki.com/miata/wiring.htmlBlack/White is your +12 supply. Brown/Yellow is coil 1, Brown is coil 2. The schematic shows a fourth (Black) wire providing primary ground, however I believe this ground point is local to the coilpack itself- no corresponding wire in the connector. So Tim is right- no RPM wire to worry about.
Coil:1
Black/white = power
Brown/yellow = coil 1 trigger
Black = ground
Coil:2
Black/white = power
Brown = coil 2 trigger
Black = ground
There is no tach output. Tim is correct in saying the ECU provides the tach signal
