Yeah, you do. It's a PCM-controlled clutch relay, regardless of the climate control head. Most Fords had gone to this type of setup by 2000-or so. Some way earlier, like my old 89 SHO. Some, a bit later. The PCM, based on its inputs and programming logic, has complete control over the operation of the clutch.
