But since there's not a white, I have no idea which is neutral. I tried hooking it up as pictured, but only the red wire had any power (and the switch wouldn't work).
If I put the red in "line" and what was in "line" instead into "load", I at least get the led on the switch powered but the lights don't actually work.
I can confirm at least that (from the picture of the new outlet) the red and "line" wires are in the same sheathing from the wall.
Any guidance would be appreciated!
