Volumetric Alarm Sensor

I just got this advice from Duncan from "The Community"

According to my circuit diagrams the two wires go to connector C0660. Pins 15 and 31.

However this diagram also has a mistake as it shows two ground connections, and only one 12v. It's clearly wrong as the actual wiring has two 12v feeds and one ground.

I can see from the thread why there's confusion over connector numbering. The C2 does not refer to C0662. Remember the workbook will have been written by the Engineer who looked after the BCU(Body Control Unit), and she will have been referring to C1, C2, C3 as they are numbered on the BCU itself. Only later as the circuit diagrams for the whole car had numbers allocated, would C0660 have been assigned to connector 2 on the BCU.

C0662 seems to be for the ATC(Automatic Temperature Control) functions that the BCU looks after.

I have been advised by Duncan to use the circuit diagrams rather than the workbook, as the workbook is correct.
