How to Wire 4-Way Switches

Electrical Question: I can not seem to find the correct diagram for my 4-way switch configuration. I have 14-2 power into a 3-way on one side of the room, then 14-3 into a 4-way and from the 4-way 14-3 across the room to another 3-way. My problem is I have the power wire(s)from the light to the box where the 4-way is located. I cant find a diagram where the light is getting power from a 4-way. Everything I have found shows the light on the end of a run w/ a 3-way switch.
Thank  you.

Wiring 4-Way Switches to Control Light Fixtures

Understanding Four Way Switch Wiring

Wiring 4-way switches

• Tim, 4-way switches work with 3-way switches. When more than two switches will be used to control lighting 4-way switches must be installed between the 3-way switches.
• There are several ways to wire 3-way and 4-way switches, and typically the cable leading to the light fixture is installed to the switch box that has the power supply cable because of the required neutral for the light fixture.
• The resources below provide links to wiring diagrams that will assist you to wire 4-way switches.
