Three wire cable runs between the switches and 2 wire cable runs to the light. It is true that there are several wiring configurations for wiring 3 way light switches and all of the wiring configurations will depend on where the incoming circuit power is located and once that is identified the rest of the three way wiring connections are straight forward. This diagram illustrates another multiple light circuit controlled by 3 way switches. The two hot wires of three wire cable connect to a pair of brass colored traveler terminals on each switch.
In this diagram the electrical source is at the first switch and the light is located at the end of the circuit. The black and red wires between sw1 and sw2 are connected to the traveler terminals. Pick the diagram that is most like the scenario you are in and see if you can wire your switch.
