installing a small flip micro switch for it to go up and down as i desire. too much headache trying to figure out what's already huge mess of spaghetti inside the dash. i did trying to look for that other blue wire but at this point, it's too much hassle to try out each wire connection. thankfully, i use the antenna turn on only for antenna and my amp turn on lead is from different wire. i will post brief reviews and pics later.
