Yes, Ford's OASIS system can tell you if the wiring harness recall has been done on a particular car. You may need to go in and talk to them; I'm not sure they'll go to the trouble to pull the OASIS record for the car over the phone (but this probably depends on the individual dealership).
Note that the forums over at flatratetech.com have an OASIS section (active techs will pull OASIS records for you) - but you have to have 50 or more posts on the forum before you can use it.
If you're serious about a '95-'97 Contour project car, you'll want to make sure the harness recall has been done. Mine lasted longer than most (low miles helps), but then I found cracked insulation all over. Thankfully, my dealer was cooperative and replaced all harnesses without hassle.
Note that some folks have replaced the harness themselves. If you plan on a 3L anyway, replacing the harnesses with the engine out isn't as big a deal.
