On-off switch set at "OFF". No ground connection to controller: unplug #6 terminal connector and check black wire for proper ground. Brake lights dead: check fuse and stop light switch. No signal from transmission speed sensor: unplug #6 terminal connector at controller and check resistance between red and white wires at harness (should be 1600-2400 ohms); if circuit is open, check resistance across sensor terminals (if open, replace sensor; if 1600-2400 ohms, replace harness).
