1996 SL600 Terminal X4/10 Connectors 61e and 87L

[Roncallo]

The attached photo shows the terminal block X4/10 located behind the passenger side airbag on my 1996 SL600. I am having difficulty understanding the functions of terminals 61e and 87L.

What I really need to know is when should these terminals be hot and how do they get there power. Looking at the wiring diagrams:

The 61e terminal is connected to the following:

Airbag Module N53
ADS Module N51
Exterior Lamp Failure Monitor N7
Instrument Cluster A1
ESP Module N47-5


The 87L terminal is connected to the following:

Basic Module N/16
ADS Module N51
Transmission Control Module N15/1
Shifter S16/9
Instrument Cluster (Check Engine) A1
Steering Angle Sensor N49
Level Adjust Switch S77/1

One of these modules must be providing power under the right conditions:

Anyone ????
