You don't need to connect anything back to the radio. What the radio wants is irrelevant since you are installing a switch to put the antenna up.
Top spade: Ground.
Middle: To antenna - NOT radio
Flip the switch and 12v is sent to the relay to put the mast up. Flip it off and 12v is removed and the mast goes down. I have this same system in my car because the new Pioneer NEX8100 puts the stupid antenna up whenever it is powered on, even if you're watching a DVD or listening to something off bluetooth. Wired up (what appears to be) the same LED switch as you to bypass it.
