3 pin, colorless, wires.

Hey there, I've looked everywhere for the past 10 minutes so I hope this is ok. I need assistance identifying the wires of a fan. The model number, or what I used to search it up on Google, is Cooler Master a14025-12CB-3bn-f1.
I'm trying to identify which wire is which, and they're all white/silver, except one also has a black mesh printed along the wire in strips. There are very very tiny words at the end of the wires, but I can't read it for shit and was hoping someone might be able to help?

I'm on my phone at the moment and not able to upload an image, but I will if needed? I just want to know which of the wires is the one that reads the rpm. Typically it would be yellow, but in this case, they're all white/silver

Thank you

You can watch from Google that how those wires goes. its MINUS - PLUS - SENSOR

the position for those cables are the same but in new fans they also use black cables.

@Sanzufin, thanks for your response, the thing is I know about the MINUS - PLUS - SENSOR bit, the thing is I looked up the fan and the positioning of the wires appear random, but colored across the board. I fear I'd risk having to go through the trouble of soldering if I get a wrong cable cut off.
(I'm trying to install a new fan, 3 pins, into a power supply block which can hold only 2 pins. The sensor wire isn't needed in this case which is why I wanted to cut it off so the 3 pins turns into 2 pins)

EDIT: here's an image I found off Google. I'm not sure if it's clear, but what I'm trying to illustrate is that the wires are all white/silver, and just bare under the insulation
