What you should use are the black (-) and white or yellow (signal) wires. Black goes to the Common terminal on the microswitch. The signal wire connects to either the Normally Open or the Normally Closed terminal.

Agreed x100.
I will add that it is IMHO good practice to use a pick to undo the red wire's clip at the female end and remove the cable and metal terminal from the plug... you could call it extra insurance against shorting.
