Anyone use an alternative power source to connect the VCM TUNER II? I have 2014 EXL and the only way to connect the ring terminal to the positive battery post is the 10mm bolt used to clamp the cable to the car battery. I thought there was another bolt under the plastic cover to connect the ring terminal but there is not. I tried connecting it to the bolt on the cable clamp but it interferes with the plastic cover no matter how I bend the ring terminal not to mention it looks hokie and I also see nothing but future problems with corrosion with this connection. Is there another source available under the hood or do I have to run a line to a fuse panel inside the car??
