Made left and right nav/strobe wiring. Attached left and right ground wires to wing tip close-out skins. Trimmed and stripped nav/strobe power wires in each wing tip to match the length of the nav/strobe ground wires. Crimped a female Molex pin onto the end of each nav/strobe power wire. Snapped the female Molex pins on the ends of the nav/strobe ground wire and nav/strobe power wire into a male Molex connector housing on each wing tip. Tie-wrapped the nav/strobe ground wire to the nav/strobe power wire near the ring terminal on each wing tip as directed.
