uses tabbed folders. Interface was also based on SAE schematic. Have
ISO 9141 and VPW. ISO 9141 is just 10.4 Kb rs232 so can probably
connect straight to computer.
I did get some sample connectors from DELPHI, the last I heard, they
only sell a complete connector about $50.00 ? Some spade connectors
will work
