Low Inductance Cable for ECU Injectors

Common rail system (piezoelectric injectors) use harness with low inductance cables between ECU and Engine Injectors.

This cables have one drain-wire. This is used as a "circuit shield", and there is a common "circuit" between ECU - Injectors (1-4 injectors and 2-3 injectors).

My first doubt is related with: This drain-wire is used only for electromagnectic field that is created (to avoid bad communication between ECU and Injectors) or is there any other reason for that.

Second, and this is a question: Is there any problem if a miss connection append between injectors? Means insted of 1-4 and 2-3 we have 1-3 and 2-4 (only drain-wire).

Please let me know if more detail is necessary.

Thank's
