## Discrepancy

LEFT HAND TAXI LIGHT INOPERATIVE.FOUND NLG WIRE HARNESS HAS OPEN IN WIRE. REMOVED AND REPLACED WIRE HARNESS PN - 8469800-1. DURING REPPLACEMENT TECHS DISCOVERED THAT MATING JACK IS NOT PROPERLY CLOCKED TO AIRFRAME. CONSULTED OEM AND CONFIRMATION WAS OBTAINED THAT DURING THE MANUFACTURE PROCESS,THE JG028 WAS INCORRECTLY CLOCKED (90-DEGREE)TO THE ON THE AIRFRAME SIDE. THEREFORE, THERE WAS A MISMATCH OF THE NEW MATING PLUG PG028. RECEIVED INSTRUCTIONS TO RE-CLOCK THE BACK-SHELL OF THE JACK (J028) SO THAT THE KEYWAY IS POINTING UPWARD (12 0'CLOCK POSITION)WHICH IN TURN WILL PERMIT THE NEW WIRE HARNESS TO PROPERLY FIT.
