I'm having trouble figuring out how to connect or if I can connect two dimmers to the switches below. I can't see any neutral wires. The switch on the left has 3 wires connected. One of them(marked in red) is connected to were the neutral should be, then runs to the second switch. It also seems to be a passthrough. Removing it, will kill the power to the outlets in the room. I have the PD-6WCL-WH-C. Also, my electrical knowledge is close to zero.Any help would be appreciated.
