sorry it took so long everybody but here is a video I made showing how to wire your G.G. underwater headphones for your ctx. I am sorry for the poor quality, all I had was my phone camera and one of my sons helping. I didnt end up taking video when I did the epoxy as it was to difficult to hold and work at the same time and my helper decided he wanted to play some basketball. LOL
