I had the problem with my o7 gt shaker 1000. Pulled every fuse to the stereo and amps and no more drain. Have not fixed, car is loud enough that stereo volume required making me deaf, so have left disconnected
Although I have an s197, I got the cue ball round shift knob white with blue graphics from CJ Pony parts and it looks and feels great.
