How do you wire up a switch to control the radio antenna? I know it's been covered a million times, but I couldn't find a detailed diagram. Can anyone help me out? Thanks!

 

What do you mean "control" the power ant., it is controlled by the HU.

If you want to control when it goes up, all you have to do is install an on/off switch, [1A switch will do] on the power ant. control line, [brown/white] in oem radio harness of an ITR, [if that's what you have]... http://www.installdr.com/Harnesses/HA-Wiring.pdf cut the lead and install the switch in the line. 94
