There are 2 systems I know about.

If the car has a EZL it should have a single coil and distributor. My 91 300SL M104 3.0-24 Valve has this. The fuel control is Bosch K jet / CIS

If the car has multiple coils, they are triggered by the engine computer. My 97 SL320 M104 ME 2.1 engine control.

I had though the 93 - 96 HFM -SFI had multi coils and used engine computer to trigger the ignition.
Sorry, typo on my part. It is a 1995 S320. Do you know which module in the box is the ignition? I'll post some pictures here in a minuite.
