 The LO-Z wiring is individually routed from the processor to the tank units and compensators.

 (18)
 The HI-Z wiring is connected in "daisy chain" between the tank units and compensator with only one HI-Z wire terminal at the HI-Z/LO-Z connector. One HI-Z wire goes from the HI-Z/LO-Z connector to the processor.

 (19)
 The tank wiring harness does not require FQIS field calibration.

 (20)
 The end terminals of the tank wiring harness at the tank units, compensators or densitometers can be repaired by replacement of the end terminals. All other damage to the tank wiring harness will result in replacement of the harness.
