I'm wondering if you could abuse an NPN sensor, which switches the GND side, to do this? Looking at the first link you provided:
that switches the load to GND, so if you take the black wire and connect it to the KC868 input, with the KC868 and sensor sharing the same +12V and GND, that might work. You'd probably want to get one or two of the sensors first and check that the black wire is open-circuit to GND when not triggered and closed-circuit to GND when triggered before you connect them to the KC868.
