It's not just a cable. There are transciever IC's that are either either in the
connector or built into the cable (i.e., pregnant snake). Your laptop interface
is RS232 there are three different protocols that are used by the various
manufacturers, you need the active components to translate from the interface
in your car to the RS232 in your laptop.. I purchased my cable from this guy
http://www.obd-2.com/ and use his software (the software is free). He regularly
updates the software and keeps the tables of manufacturer specific codes up
todate too.
