I am an electrical hobbyist, and I am looking at making a little add
on to my Mercury Grand Marquis. I want to use a little processor, and
read the computer codes on the Mercury periodically, among other
functions. My problem is I can't find any technical information on the
protocol/error message definitions. If any of you have run across such
information, I would greatly appreciate it if you could send it to me.
