The air suspension pump on a 1992 Cadillac Eldorado is typically located in the
rear of the vehicle, near the spare tire. However, the exact location can vary slightly depending on the specific model and trim level. It's usually attached to the frame or body near the rear suspension components.
You'll likely need to look under the car to locate it. It's often a fairly substantial unit, and might have some associated air lines running to it. Check around the spare tire well and along the rear frame rails.
