fan question

[Nismo24zero]

i bought fans out of a 95 nissan altima and each fan has 4 wires they are blue, green, yellow, and black when i wire them up does anyone know what the colors mean i figured that the black means ground. im running them on a toggle switch so i can turn them on manually i figured that summer is comming up so i would wire them for high speed. i just wasnt sure which one was the power wire. i have searched on both google and nico but couldn't find quite what i was lookin for so if anyone could help me with wiring them in i would appreciate it thanks
