I have a car antenna with red and white wire going into the controller on the antenna ( Relay ? ) a green wire ( with inline fuse ) and the blue wire are mounted on a switch - does anyone has a wiring/hook-up diagram?

Thank you for your help

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 for fully automatic mode. Apply 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.
