was discussing the possibility of streaming data from an OBD-I port like what is possible in OBD-II. i know that they have a Data + and Data - bus on EEV-IV similar to OBD-II. i never heard of them being used for anything as the self test uses different wires. even on the wikipedia page states that they added the 2 data bus wires for sensor streaming. while im sure its not compatible with OBD-II readers (maybe on some?) does anyone have any info on the ability of using this data bus for anythnig usefull?
this was what was on wikipedia
they are not the self test wires as it is on the seperate 1 wire connector

Early EEC-IV equipped cars don't have the capability to send sensor data through the diagnostic connector to a scan tool, unlike GM cars.....By the early 1990s certain Ford/Lincoln/Mercury models had sensor data streaming capability. The feature is called DCL (Data Communications Link). These models have 2 additional data bus wires to the EEC-IV diagnostic connector).
