WARNING: This page is about a different car, the 2002 Mercedes-Benz G500. However, it is still accessible from the selected car via links, so may be relevant.
Manufacturer recommends using Socket Box (129 589 00 21 00) for making measurements to prevent damage to electrical connectors and terminals. See Fig 1 . Manufacturer identifies all system components with an alphanumeric identification (i.e., N3/10 is for ME-SFI control module).
NOTE:
When connecting test equipment, disconnect ME-SFI control module connector "D" first. When reconnecting connectors, connect connector "D" last. See ME-SFI CONTROL MODULE CONNECTOR IDENTIFICATION
