K8 Engine Query - "ISC" unit

  • Hi the drawings in the '95 K8 PDF refer to an "ISC" unit. It seems to be located under the air inlet /Throttle position area. It has a 2-pin connector (wiring colours white /red stripe and blue/orange dash). As I'm currently attempting a 'simplified' wiring diagram, I wonder if anyone can tell me it's purpose. It connects into the main engine loom going to the ECU as far as I can tell ? Thanks

  • The PDF wiring diagram also refers to it as the "IAC" valve. Inlet Air Control maybe ?
