its a honda accord power antenna but its in my 89 prelude. I pulled it out n tested it on my battery charger. works fine that way there is a black(ground) red n green wire. Now its hooked to

Yellow/white-old wire from previous power antenna? Which has power.
White/Yellow- dunno what wire that is. No power to it.
black-ground. duh no power of course

As of right now it was hook up
Black-black from antenna
yellow/white-green wire from antenna
white/yellow-red wire from antenna.

Anyhelp would be great.

 

White/yellow wire is to feed +12v to antenna while stereo is on.
Yellow/white is permanent +12v,
Black is ground.

Try swapping over yellow/green and white /red wires.
