Tank level indicator wiring

[Jkdstar]

Water Tank Indicator wires. I can't find the diagram for what color wires attach to which holes in the actual water tank? I have 6 rubber holes coming from the tank with a 3 hook red wire not attached to anything (guessing ground of some sort). And then a Yellow, Orange, Red, Grey, and Green coming from the wall (I'm guessing the switch that runs the pump by the sink. Or do the colors even matter which one is in which hole?

What is the brand of the Monitor Panel? If it's a KiB, that company used to publish a lot of support info. Seems they've "cleaned up" their web, I couldn't find much.

Try gOOgle "kib monitor panel wiring diagram k-21 2f" without the quotes, you can experiment from there, changing that search a little here and there.
