The Infinity ECU (PN 30-7109), when combined with the Plug & Play Adapter Harness for the 2001-’05 Porsche 996 Turbo M/T (PN 30-3902), completely replaces the factory Porsche ECU and does not require any additional accessories, sensors or modules for proper operation. Installation can be completed in about an hour when using all of the factory sensors. The manual transmission 2001-05 Porsche 996 Turbo M/T Plug & Play includes several unique features that incorporate the Porsche’s factory CAN bus system (see "Features"). This adapter will not interface with the C4 model.
