There is only one wire, usually blue on modern head units which is live only when the head unit is switched on.
As we don't know what head unit you have you will have to check for a switch output from the unit, or use an independant 12v supply as already stated.
A wing mounted electric powered aeriel uses that supply but the aerial is raised or retracted via a switch and relay so turn the unit on and upgoes the aeriel..
 
If your planning any off roading fit a rubber type arial like i did then it wont break and you wont have to worry about the electrics
 
Thanks all. It's a Sony stereo, it's the wire from the arieal that I'm looking for. I do some greenlaning, that's why I could do with sorting it so that I can get the areial to retract, just dont know which wire in the blocks that plug into the stereo is for it
