Hi- Can someone please verify which wires from our old 3-way non-dimmer switch go to which ones on the new 3-way dimmer switch? I wasn't able to piece it together and don't feel like burning our house down. Thanks in advance. Pictures attached. New switch is Lutron.

I am attempting to install a replacement light fixture in our utility room and it appears the existing box is wired into a switch loop. A little summary: [list] [*]The original light fixture was one bulb, I am replacing with a two bulb fixture [*]There is one red and four wire bundles (black, white, and ground) coming in to the box (see attached image) [list] [*]One bundle is directly from the switch [*]One bundle is directly from the power source [*]Two bundles go to other lights, outlets, and smoke detectors [/list] [*]Switch is wired with BLACK on top and WHITE on bottom [/list] Now I have tried a few combinations that seem to fail in one way or another. [list=1] [*](Switch White to Black Source) + (Switch Black to Light Black) + (Light White to White source and outgoing white) [list] [*]No light [/list] [*](Switch White to Black Source) + (Switch Black to Light White) + (Light Black to ALL white) [list] [*]No light [/list] [*](All White to Light White) + (Switch Black to ALL Black) [list] [*]Light but no effect by switch (duh!) [/list] [/list] There was one other combination, I didn't write down, that caused the switch to function, but would trip the box if I tried to shut it off. I would greatly appreciate any help I can receive on this and will post any other info that is needed. Thank you all.
