Motorised sedan rear antenna help!

[Diabolical EG]

My previous JVC headunit was stolen and the old man bought a cheap temporary hu but now it's not wired up properly so my antenna is stuck at the highest position and can't be lowered(looks like a warthog)
so can u help me find the correct wiring that control my motorised antenna

look in the wiring diagram that came with the head unit. it should show which wire is for the power antenna. that is if it has that option of course.

It's the blue wire but i can't find the wire(s) from the antenna it's just the 1 for reception

i tihnk it has to be wired into the main power for the radio, that way when u turn the radio off the ant. goes down, the other ant. wire is for reception.
