FOR EXAMPLE, SUFFICIENT DAMAGE TO THE WIRES COULD RESULT IN THE LOSS OF VARIOUS EXTERIOR LIGHTS, WIPERS, THE DRIVER’S AIRBAG TELLTALE LIGHT, THROTTLE CONTROL, DEFOG CONTROLS, OR TRAILER BRAKE CONTROLS. IN ADDITION, WHILE THERE IS NO EVIDENCE OF ANY STALLS RESULTING FROM THIS CONDITION, IT IS POSSIBLE THAT IF THE RUN/CRANK WIRE WAS SUFFICIENTLY DAMAGED, IT COULD RESULT IN AN ENGINE STALL.
