Modification – Wiring Protection Addition (1) Behind the wardrobe, in the area of the crew oxygen reservoir, inspect the electrical wiring connected to the following connector, P1WQ and surrounding components for signs of damaged insulation, abrasion, or chaffing. The following wires require inspection: (Ref. Refer to the Wiring Manual, Chapter 35-21-00). See Photo 1. (a) Oxygen Pressure Transducer MT1WQ with connector P1WQ, (consisting of 2 single wire conductors, 1 twisted-shielded pair, and 1 shield return wire (respectively): WQ1G24, WQ10A20N, WQ2A24WHT, WQ3A24BLU and WQ4A20N (wire for shield return to ground)). (b) Low Pressure Switch S1WQ with connector P5WQ, (consisting of 2 wires: WQ22C24 and WQ19A20N).

Photo 1 (2) Make sure that the harness is not coiled, and that there is no excessive slack, ensuring a minimum clearance distance of 0.5 inch even with harness movement, per Standard Practices Manual, Section 20-12-00 “Wiring – Maintenance Practices”. (3) If necessary, trim wiring to length or push any excessive slack back into the main harness, while maintaining a drip loop (with connectors mated), per Standard Practices Manual, Section 20-12-00 “Wiring – Maintenance Practices”.
