the white/red is the MS PNP. it comes ready to plug directly into your factory harness. Both can be made to run the car completely. MSPNP is only available for 90-97 Miatas.

MSPNP is not OBDII compliant where as a custom built MS made to run in parallel with your stock ECU can be OBDII compliant.

new MSPNP = $700+
you can build a custom MS with all the bells and whistles for $300ish
