In the diagram above splices are made and a three conductor cable is installed between all the switches. 4 way switch wiring diagrams this 4 way switch diagram 1 shows the power source starting at the left 3 way switch. It shows the components of the circuit as simplified shapes and the aptitude and signal friends amongst the devices.

Install the idevices dimmer switches according to the diagram. This 4 way switch diagram 2 shows the power source starting at the fixture. 4 way dimmer switch wiring diagram this is the wiring for a dimmer in a 4 way circuit.

To make this circuit work a 3 way dimmer can be used in place of one or both of the standard 3 way switches. The dimmer s hot wire through the air gap switch. Using a ballpoint pen put an x in the box to indicate that this is the secondary switch.

Thus the blue wire is used to provide power to downstream key pads in 3 way 4 way scenarios in order to ensure that all power to the load has been removed when the air gap switch is open. Install the dimmer switches into the gang boxes and install the faceplates. I figure the rarity of use for 4 way dimmers combined with the rarity with which they would be purchased make them not worth manufacturing.

Three wire cable runs between all the switches and 2 wire cable runs to the light. Four way switch wiring diagram with the line and the load in the same switch box. Free quick start guide here.
