Most aftermarket replacement power antennas seem to have
three wires.---------
In most cases the wire colors are red, green and black. The red wire is hooked to a
constant 12v source, the green wire is hooked to a conditional 12v source,
usually a power source from the radio that is controlled with the radio on/off
switch and the remaining black wire is connected to ground.
The green wire provides power to raise the antenna. When the power from the
green wire is removed(i.e. radio turned off), the power from the red wire
retracts the antenna. The green wire power source could be controlled by an
on/off toggle switch, if its connected.
------------
But in some power antennas the wire color is : black, yellow, and orange. The black is
ground, the orange is +12 v at all times, and the yellow is switched On makes
it go up, off makes it go down. Usually this is controlled by the radio.

You will need a 12v source to connect to the green wire via
any type of on/off switch. You can not use a momentary toggle switch for the
power to the green wire. You will need an on/off (toggle) switch so that power
is sent to the green wire as long as the switch is in the on position, to hold
the antenna extended. The red wire can be connected to any constant 12v power
source, such as headlights, dome light, any relay power terminals or a
cigarette lighter. While your fuse panel does not have an antenna terminal, you
could connect it to any fuse panel terminal that has constant 12v power. This will help.Thanks.Keep updated.Helpmech.,
Connect the green wire to one side of the toggle switch and a 12v source to the
other side. For the toggle switch power, I would use a 12v source that is
controlled by the ignition switch. That way, if you forget to turn the toggle
switch off, when you turn the vehicle ignition switch off, the power will be
cut to the toggle switch and the antenna will automatically retract and not be
draining the battery when the vehicle is off.
As for fusing the power to the antenna, its always a good idea to fuse all
power sources. Chances are that you will connect it to a power source that is
already fused at the fuse panel, but the additional power draw to the antenna
may overload the existing circuit. I agree that inline fuses are a PITA, but
the installation of an inline fuse to the antenna would provide a level of
protection to the antenna and protect the circuit you tie it to from additional
overload.
I would mention that the antenna should be fused for around 10 amps. IMO, the
cigarette lighter circuit would be best because this circuit is used the least
and wouldn't tend to be overloaded by the addition of the antenna power
requirement.-----------
