The instrument cluster of your 2002 Lincoln LS is mechanically simple to replace, but requires programming with a special tester. The New Generation Star Tester with a Ford Service Function card are used to store the existing configuration and program the replacement. Check with auto parts stores and Ford-Lincoln-Mercury dealers for a tester you can borrow or rent. If you check around, you may even find a location that is willing to operate the tester for you, or will at least show you the basics of its operation.
Retrieve the module configuration for the instrument cluster module using the New Generation Star Tester. All official replacement instrument clusters are packaged with a multi-language sheet explaining how to configure the module.
Unbolt and remove the hood release handle. Remove the lower cover from the steering column. Pry off the outer instrument finish panel, then unscrew and remove the inner finish panel. Unplug all visible electrical connectors leading to the instrument panel.
Unhook and remove the heat duct for the floor vents. Unbolt the brackets that retain the steering column and gently lower it. Unbolt and remove the instrument cluster.
Install the replacement cluster, following the reverse procedure. Download the saved configuration from the tester to configure the module.
