The hot from the power source is spliced through to the common terminal of the switch SW1 via cable C1. The travelers from the switches, via C1 and C2, are spliced through the fixtures,and joined by cable C3. The hot to the lights comes from the common terminal of SW2 via cable C2 where it is spliced to the hot of of LT1 via cable C4. Two, 2-wire cables C3 and C4 run between the fixtures, and a 3-wire cable C2 runs from the second fixture F2 to the second 3 way switch SW2.
