Found a .pdf file
that shows LSDC163pwv ... it does not show wiring for LSDC
. It shows wiring for other 3-way dimmers & separate wiring for 3-way fan control. This is a clue.

download page does not load, so I can't see specific manual. Let me provide what I know
-Instructions might be confusing because LSDC works for both single-pole and 3-way circuits ... which probably adds a lot of extra wording in manual
-LSDC Device has single-pole/3-way dimmer (this requires 3 wires)
-Device has single-pole/3-way fan control with 3 speeds (which requires 3 wires)
-That's 6 total wires
-If I understand correctly, you just want to control a ceiling light? -And you do not have a fan? And your ceiling light is set up with 3-way switches.
-IF you are also wanting to control a fan in addition to the light, the box will need separate wires that go specifically to the fan
>> your description shows that you do not have separate wires for the fan. Is this correct?
-Without separate wires to the fan, you can still control the light ... but if wires to light also turn the fan on-and-off, then the LSDC is not the right control since a dimmer for lights will not work on both fan and light.To wire the light
-You have identified black common wire for light (it is connected to dark-colored screw on 3-way switch)
-You have identified travelers that connect the 3-way switches
-The neutral wires seem to be twisted together at back of box.
-I think the dimmer is located on the top, and fan control is bottom?? Not 100% sure >>>
-Question: are there 3 wires that are associated with dimmer?
-If you can see 3 wires for dimmer, one of those wires should be black ... just hook that to common, and hook other 2 wires to travelers ... and see if it works. If not, keep connecting them until correct combination is found.
Tip- I read a lot of electrical part manuals, and when confused, I write out the instructions so it breaks down the information.
