Misc ecm questions

Ref gm ecms, TBI/TPI

Just to make sure I got it straight.

All C3 are 160 Serial Data,  and pin out at ALDL terminal E

The 1227165 can be either 160 or 8192 so may be at E if 160,
     or M at ALDL is 8192

All P4 are 8192 (except 165), and are pinned at M at ALDL

What is a DERM, on a 1227730 ecm'd F-Body?.

The VSS buffer on a late model F-Body generates, the same output
as a optical speedometer sensor?.

Does anyone know of a 1K ohm coupling (or isolation a better phrase)
transformer?.
