Well, actually, pins 2, 4, 5, and 16 are standardized.
Pin 2 is the ECM/PCM data.
Pin 4 is chassis ground.
Pin 5 is signal ground to the ECM/PCM.
Pin 16 is battery power.
With the wide part of the connector at the top, the pins are
numbered L-R 1-8 and the narrow part on the bottom is numbered L-R
9-16.
\ 1 2 3 4 5 6 7 8 /
\9 10 11 12 13 14 15 16/
The other pins are manufacturer specific.
