Engines without E-Gas: 
The kick-down switch is integrated in the accelerator cable in the plenum 
chamber, behind bulkhead -arrow-.  
Engines with E-gas: 
The kick-down switch is integrated in the throttle position sensor and 
Sensor 2 for Accelerator Position (-G79-, -G185-).  
A learning procedure must be performed for the shift point of the kick 
down switch for engines with E-gas. If the throttle position sensor (-G79-, -
G185-) is removed, exchange the engine control module or disconnect 
the battery. Learning procedure can be found in   Repair Manual, Fuel 
Injection & Ignition, Repair Group 24; Kick down shift point, checking.
