Yaw sensor is located just aft of the gearshift (small box bolted to the transmission tunnel).
Hope that helps.
I don't think that will work for the dyno TimeLord; as soon as you pop any of the wheel sensors the CAB module with throw a code and the spoiler will pop-up and you'll get the dreaded rev limit. There again there do seem to be some differences between the model years from what others are posting. Worth a try I guess. The only way I could fool the thing for was to feed a front wheel speed signal into the CAB unit so the car thinks its moving. The YAW disconnect just disables the ESP on mine, not the TC or wheel sensor failure detect.
