[V8] On the road to recovery - was ECU grounding, etc. (abridged)

[Coleman, David]

Yup... Though I must admit the silver lining was having a reason to
clear the cat out!  I was going to delve back in last night and unplug
the O2, but it was almost 2am.  I'd dropped a windshield washer nut down
the water escape hole under the cowl, and when I had trouble finding
such a simple replacement nut, I embarked on a garage organizing
adventure.  That took me from 9pm to 1pm.  By then it stopped raining
and I finished replacing the maf and putting 'er all back together.

So I guess I got to Pittsburgh via Shanghai, but learned a bunch about
the wiring setup in this car that I'd been able to avoid previously.
