Haze machine remote control pins

A friend is trying to control a haze machine, via it's 5-pin DIN remote control input.

Q1: Does anyone know which pins need to be connected to turn on the haze?

In this video (https://www.youtube.com/watch?v=9N\_5diiYLPI) his relay connects the red, black and white wires. But the video doesn't give any information as to which pins they are!

The model he has is Kam Atmosphere haze machine.

Q2: But do all haze machines have the same pin connections for their remotes?

Q3: The machine has +5V on one of the pins. Is there any danger of blowing something in the machine if he accidentally connects this to the wrong pin?

Thanks for any advice.
