phono plug connections

[tknick]

I recently purchased two fans that I need to add the phono plugs to so they will work in the existing light fixtures at the bunkends of the PU.  I purchased the plugs from radio shack, but when I opened them up I found three connections inside the plug (presumably left and right channels and ground).  Anyone know which ones to use for the fan hook up?  There are six possibilities and I rather not figure it out by trial and error if I can help it.  I also don't want the fan spinning backwards!

any help would be appreciated

return the stereo plugs and buy monoral. Only two contacts. center contact is hot.

If returning the plugs is a bother, the hot is the tip, the ground is the sleeve.  The ring isn't used.

Radio Shack is a bit of a drive and I threw the reciept away just after I posted the message. I'll make do with what I've got.  Thanks for the answer!
