Never having to worry about plug wires again. Less emf interfering with other sensors. Props from your friends for pimping your own ride.

If it can fire the oem coils it can fire these as wasted spark. I tried them that way before going sequential just to see if it would work.

Yes. It'll work with the stock ECU or any other ECU that can fire the Miata coils. You will need a "higher-end" engine management system if you want to run them sequential. Otherwise you can fire them 2 at a time. 1&4 and 2&3 together.

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.

Yes, you're missing the wiring diagram

http://www.madracki.com/miata/wiring.html

Black/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.

According to the schematic for '00...

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

Attached - Toyata Corolla '04 schematics.

I couldn't attach it to the thread. Maybe an admin can do that.
