Important Note: There's no single definitive visual guide as the exact location and accessibility might vary very slightly depending on the specific differential used in that particular vehicle. It's recommended to consult a repair manual specific to a 1995 Ford Thunderbird LX. These manuals will have diagrams and detailed instructions to help you locate and replace the sensor correctly. Working on the differential is not a simple task, and if you're not mechanically inclined, it's best to take it to a qualified mechanic.
