The ECT Display Driver is a small module with a removable wire harness that mounts behind the driver’s foot well cover. All wiring connections are near the ECM and only 4 wires are needed for basic operation:
• +5v power from the ECM (T-tap)
• Ground – available at ECM mounting bolt
• ECT sensor wire (T-tap at ECM)
• Dash temperature gauge wire (must cut at ECM)
