3 wire is for fan speed , pick one, black or red , one is for high speed and one is low and then tape off unused wire on fan.hope that helps, if not i will try to explain better.

Wiimb are you talking about wiring up a adapter cord to your fan?

Isn't Black - & Red + & the 3rd wire the speed control and if not used the fan will run at full speed? I'm pretty sure this is how old school PC fans run. I'm assuming that is what you are trying to hook up??

Actually 3 wires can be...

Live , Negative , Ground

I have a fan here that I use in the summer and it uses a PC power cord and uses all 3 prongs.

are you talking low voltage pc fans?

or a regular fan? in Europe or N.America?

First of all are you using AC (house and utility) or DC(battery). AC power uses hot and neutral , black & white. DC power uses positive and negative, red & black.
So what style fan is it and what voltage?

Exactly, easy to install either way. If AC you can just cut an extension cord, connect your wires to it, and then plug it in

Maybe the OP should respond before we keep going on.
