Ok, but where and how do I get hold of this circuit? And where is it documented to set it up?

edit

I've ordered the IC from Mouser, was $4.73aud

Is it as simple as this? Where do you place the diode for flyback?

Is not miata alternator controlled by just logic level pwm signal? I believe my 2001 miata controls the alternator with only frankenso as is.

On dodge neon yes we used that large mosfet with the small addon board. I need to document better when i get home on Saturday

Yes, you are correct, I thought we still needed some external chip before the alternator.
