I've searched for and found nothing concrete on a wiring diagram for a 3 wire aftermarket electric antenna. I know the yellow wire is supposed to be power the black ground and the two blue uses the button on the radio. When I connect the red wire to the yellow and the ground to ground the green won't work on either blue wire. The only way I get it to move is when I connect the red and green wire to the same blue wire of either one. But it won't go back down when the radio is off or you press the button. How else.do I need to wore this to make it work?
