It seems to be wired up correctly (image 4) however:

Have you physically measured the wires all the way back to the chip?

Have you measured the supply voltage when all is connected?

With such long wires you need to put a 100nF ceramic cap across
the supply pins on the chip itself (pins 4 and 8) or the whole thing
is likely to oscillate crazily.
