Have a look here for a 94 E230 http://www.w124performance.com/docs/mb/M104/M104_ETA_rewiring.pdf
I know at least the M104 ASR cars had this, I have a 1991 300SL with such a system and a motor from a 96 E320 that still has this type of arrangement
97 was the first year for true drive by wire ( no linkage between the pedal and throttle blade ) at least on the SL320 , C280 , E320 .

Right, I'm familiar with how those engines are set up, but the OP's car is a '92 300E, which came standard with the m103 engine, which utilizes a straight mechanical throttle linkage to actuate the throttle plate.
Your 1991 SL has the more advanced 104 engine, but the 300e ran with the older 103 engine until 1993 as the standard 3.0 option.
