I got mine from well known chain Auto Store. Asked for the '95 Ford Mustang (Bosch 02). Just had to cut and splice the wires in since the Ford version ($55.00) did not come with the harness. To take out my old sensor on the W124, I sprayed some liquid wrench on it and used a long wrench for leverage and it came right out.

1990 Mustang GT sensor....$35. Splice and voila!

I've done it and everything works great, and the link by mbenz earlier (my original thread) has all the info you need. Let me know if you have any Q's.
