Pentair Intellichlor ic 40-no salt reading

My system was consistently giving me a cold water error message turning off the chlorine generator.
After a little research, I bought a flow sensor through Amazon (the Luxvoko that says it is compatible with the ic 40.
The wire colors didn’t match(blue and white instead of black and yellow , red and green matched), but I found a picture and wired it according to that.
Now the cold water error is gone, but I’m getting a reading that the salt level is 0 .on the Intellichlor, in the salt group, the low light is a solid red. When I run a diagnostic through the control panel, it reads 0 now (the salt level is probably 3300 or so… Defintely not extremely low.

Did I wire the new replacement switch wrong, or the little clip connectors not work? Or could it be a bad switch?
 
I don't know how you have your non-Pentair assembly wired but red & black wires go to the flow switch while green & yellow wires go to the temperature thermistor. You need to figure out which are the correct wires for what you have.

Thanks for the quick reply! Here’s a picture of the connections.
Both bundles had red and green, so I think those are paired correctly
The new switch had a blue and a clear/white, so I connected the blue to black, and the ‘clear’ to white.

But I’m confused about the explanation for which wires are used for what.. Two pair are for the flow, 2 are for the temperature. Does this switch not measure the salt?

I have no idea what the correct wire pairing are.

Nope. The assembly has a flow switch and a temperature thermistor that measures the water temperature.

The salinity is calculated based on the conductivity of the water and the water temperature.

The conductivity sensor is a separate device in the cell which can be seen if you look in the cell.
