I am trying to avoid having a 75 dollar labor fee to install my amplifier in my 05 gt. I have already built the box and installed it myself but i don't want to have to put in a shotty looking kill switch for the amplifier and would rather hook it up to the remote wire in the radio to kill the power to the amp when i turn the car off. Can anyone tell me where the remote wire is on the factory headunit. I have a Shaker 500. Thanks a ton stangers.
