Splice both the fan and the light hot wires together with the common wire from the SW2. The traveler wires are spliced together in the ceiling fixture box. To control the fan and light separately, a builtin switch such as a pull chain or remote control is required on the fan/light.
Here the source is at the fan/light and a switch loop runs to the wall switch. The source is wired directly to the fan and spliced through to the switch. With this arrangement the light is controlled with the switch and the fan is hardwired for pull-chain control.
This wiring arrangement allows for lowering the lights with a dimmer and controlling the fan with the builtin pull chain. The source is at the ceiling outlet box and 3-wire cable runs from there to the switch box. The neutral from the source is spliced directly to the white wire on the fan kit and the cable, running it through to the switch box.
This diagram is similar to the one above, but with the electrical source originating at the fixture. Three-wire cable runs from there to the controllers. The neutral wire from the source is spliced directly to the white wire on the fan/light. The hot source wire is spliced to the white on the 3-wire cable and then spliced to the input wires on both controllers at the other end.
