Info re battery sensor on the neg battery terminal:

The Hella part number partly matches the FoMoCo labelled sensor on my MC TDCi in 6PK 010, and looks much the same.

The meaning of ASIC in this context -
'application specific integrated circuit' it seems.

So the single wire to the +ve terminal is the supply to the sensor and the the single white wire from the sensor is the LIN communication wire.
