Put the rear sensor on the tailshaft/diff yoke. Single front sensor on preferred wheel. Input to cancel TC if foot is on brake (unless you left foot brake and may not matter if you do) . Use hall effect sensors to simplify the conditioning circuitry. Box with wheel speed comparator (front/rear). Kno...
