I spent some time tracing the wires in the Infinity Stick Grip. I made the mistake of taking the grip apart to look inside... Big Mistake. It took quite some time to get it back together without pinching any wires. Once back together I decided to use my multi-meter to find the switch to wire-pairs. There are 16 wires (actually 17, a black wire that is not used) and there does seem to be a somewhat organized system to the wire pairs. I got lucky on the very first two wires I selected and they were on the green "start" button. From there it was just a process of elimination. The black 17th wire is some kind of spare and not used.
