The four wires typically associated with the air compressor in a 1998 Grand Marquis are usually the power wire, ground wire, and two signal wires for control. The power wire provides electricity to the compressor, while the ground wire completes the circuit. The signal wires may control the compressor's operation based on various inputs, such as pressure or temperature. It's advisable to consult a wiring diagram specific to your model for precise identification.
