07 Volvo S40 FM Modulator Sirius or Ipod - FYI

To upload images, click on this button in the toolbar above the new message form. You have a power antenna. The fused lead should go to a constant 12V+. The base of the antenna needs to be grounded. The blue wire is most likely for fully automatic mode. Applying 12V+ to this lead will make it go up. Removing it will make it go down. This would connect to the power antenna output of the radio (also usually blue on all aftermarket radios). The other two leads are probably for manual mode and would require an included toggle switch. I would bench test this first before installing it into a vehicle.
