I looked at some OBD2 diagnostic data on a Dodge Ram last year.
A astronomer decoded similiar data for a pre-obd mopar over a weekend 
and posted in archives.  It is a 2 wire Rx Tx  serial, you can invert 
to rs232.  The bytes I have are 8192 baud not from the ISO-K 
line and did not seem to be any  SAE spec.  Chrysler is adapting to 
CAN bus for non-diagnostic com.  If you can not find in archives I 
can repost.  If you get any bytes I can see if they are J2178 
decodeable.
