I just got my Shark Attack II antenna from LoCustom.com and I have a question with the wiring...

Shark Attack II Wires:
Red wire (I believe it's the power)
Black Cable (I believe it's the antenna)

My Car Wires from 97 Integra GS
One plastic Adapter containing 3 wires: Red, Green, and Black (I believe one of them is the power)
Black Cable (I believe it's the antenna)

So I need to know which of these three wires is the 12V for power. Once I know, I believe all I have to do is to solder the red wire from the Shark Attack II antenna with that wire and connect the two thick black cables together. Am I right???

Thanks in advance.
