Here are some sites I've found helpful:
 
General Info
 
http://www.hex.co.za/vaginfo/index.html -- This site has an in-depth description of the "conversation" between computer and ECU.  It's for VW's, but the principle is likely the same.
http://www.carlton24v.co.uk/aldl.htm -- Simlar to the above, this site also traces the conversation between tester and ECU, for a Vauxhall with an earlier version of Motronic.
 
 
 
Hardware
 
www.elmelectronics.com -- Producer of the ELM323 chip.
http://www.andywhittaker.com -- Another great site showing several interface designs.
 
 
Software
 
www.wgsoft.de -- WIndows GUI OBD-II interface software for the ELM series of chips.
