I installed one in mine and tried to hard wire it to my Love TSS2, but it's not getting power when the second output kicks on. I'm thinking maybe I just have the two wires reversed? There wasn't a black or white wire, so I just chose one for my hot.

small blade of plug is hot, large blade is neutral. many appliance cords have markings or ribbing to differentiate hot from neutral.

I used a fermwrap for mine. I doubt that polarity really matters on a heat pad, but worth a shot.
