W140 main power lead wiring diagram

I donít have 12v at all fuses. I pulled the fuse box and see the wires screwed well to terminals each designated with a letter. I donít know how the busbar in the fuse box are lined up and connected by row. Some rows didnít even have a main connector.

Can anyone point to a wiring diagram for the fuse box, and where the conductors, especially the one that goes to ďTĒ comes from? Hoping someone knows the connector name/number and location.
