Power antenna to radio wire

[KNanthrup]

(Repeated from tech forum)

Ok, one quick question I'm hoping someone can answer for me. While connecting my amp a few weeks back, I ended up accidently cutting the wire that tells the power antenna to turn on and I just went out to reconnect but I can't remember which wire it was. If someone could let me know what color the wire is that comes from the back of the radio to control the power antenna, I would really really appreciate it. (I think it goes from the stereo to the switch but im not sure). There are a few open wires but I'm skeptical about just connecting it and finding out what happens.
