Hello miata fans,

I have a '94 1.8 Miata NA with batch fire and MS1 Extra 029y ECU, I am quite confused about the injector wiring.

I want to use my miata with the original coilpack with batch fire.

I want to wire 1-4 , 2-3 as the ignition order is it right? Which is the correct pairing? Or does it matter how the injector are wired?

Thanks for help...

 

Injectors should be paired 1&3 and 2&4

 

Ok, thanks...
