Potentially stupid question but.....is this the Harman room sensor? This "optional part" (according to my owners manual) is already connected and coiled up neatly on the back of my stove. To me, it looks like just a long lead wire with a piece of shrink tubing at the end and a female crimp fitting that would accept the actual room sensor device. However, when I search for "Harman room sensor" pics, I see what is already on my stove.
