No - the early AFM (log output, 12V input) only applies to early 944. All 911 AFM are the later 5V versions.

The engine has a fuel pressure regulator that looks at the intake pressure and adjusts fuel rail pressure so that the injectors always "see" the same pressure difference. This ensures the flow of fuel is tuely proportional to the electric pulse duration.

The AFM is bolted to the air box. First you need to get the air box out. Next there is a hose clamp that attaches the AFM to the throttle body.
