Anyone used to metra kit S14(wires) to install a headunit ? There is 2 blue wires (I guess one of them is the antenna power up/down) and I was wondering what the second one was for. I tried a “Y” to connect to my radio blue wire and now, once the unit is turned on, not on tuner, my antenna goes up. I tried wiring each one individually and on keep the antenna up and the other just doesn’t do anything. Only thing I did not plugged yet is the antenna adapter which I will in a few days. Might affect I guess. Anyone did it with the metra kit wires ?
