Disable or disconnect E320 E420 E300 alarm
For future reference, the red plug has never been related to the alarm, “facelift” or not. Every airbag-equipped 124 vehicle has an Attention label on the black metal cover plate identifying the red plug as part of the airbag and seat restraint system. If it’s unplugged, the red SRS lamp in the dash lights up warning about a problem with the airbag/SRS.
As many know, the original alarm system could be disabled by disconnecting the two black plugs from the Becker alarm control module under the metal plate in the passenger-side foot well.
In 1993, MB added an ignition kill feature to the alarm system, controlled by a relay behind the instrument cluster. So if you disconnect the two black plugs from the Becker alarm module, the car won’t start.
Here’s a link to someone who figured out a work around to disable the 1993+ alarm system while still allowing the car to start:

If you do this, post back how it worked for you
