Did you permanently earth the parking brake sensor and if so have you seen any downsides of that approach. It has been so long I couldn't remember if we decided on switching the parking brake sensor and breaking the speed sensor circuit on one button or having the bypass circuit effectively permanent and having one switch do the reversing override and the other the speed sensor.
