Here's the problem
My W124 doesn't come with switch antenna and I've installed it..
The results :
Switch and antenna work well... and i like it very much,
BUT when the radio goes off, the antenna still
stays UP 
this is my schematic :

1 & 5 only for the light
2. lead to antenna ( red wire )
3. battery (+)
4. lead to antenna (Trigger / blue wire)
anyone can help me ?
here's another pictures which maybe you can help me to figure it out...
Antenna connector,
without switch antenna requires only 3 wires, right?

(1,3 and 4)
and still 2 wires not connected... (2 and 5)
my question, are these 2 wires necessary to be used in order to make switch working properly?
Thanks folks...!!
