I've been snooping around on the net, but have yet to find any extremely useful information that didn't cost a lot of money. There is one exception, I at least found a hardware interface to the OBD-I (i think) connector in a datasheet for a pre-programmed pic from - if i recall correctly - elm electronics or something. If I make any progress with this I will post the info.
