Wiring diagrams for ESP/Traction Control? or comprehensive wiring diagrams?

I'm having trouble with my ESP/traction control unit (N47) the one that is attached to the front of the abs pump in 2003+ w163's. The unit isn't responding at all, so I suspect either the unit is dead, or the wiring loom has problems. Does anyone have wiring diagrams for the w163? I want to buzz out this loom to test it for continuity, then (assuming I fix the issue) would like to install an electric brake controller for a heavy trailer.
