Hi everyone, 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. Thanks

If your car is '96 or later, this is what you want.

You didn't even say what year it is. You should be asking this on the rec.auto.tech newsgroup.
I've seen all sorts of info on the 'net about the Fords ECS system, the info isn't hard to find.
