GM 1227747 ECM drivers

[Gregory A. Parmer]

Not to be bothered with terms then, I can
document a little based on last night's
experimentation. Nothing like answering
your own questions.

The doomaflotchy in the middle switches
the IAC lines.

The 2 transistors on the side and closest
to the connector switch the injector lines.

The transistor farthest from the connector is
apparently the 5V regulator for everything else,
but that's a little bigger guess.

I'll put up the details on my soon to be started
personal diy-efi project page.
