Installation Guide

1. Preparation: Disconnect the vehicle’s battery to prevent electrical shock. Remove any existing tachometer cable or shaft that may be in place.
2. Routing: Carefully route the Metzger S 07039 Tacho Shaft along the engine bay, ensuring it does not contact hot surfaces or moving parts. Use protective clips if necessary to secure the cable.
3. Connection: Align the screw‑in connector with the tachometer housing. Tighten securely but avoid over‑torquing to prevent damage to the connector threads.
4. Testing: Reconnect the battery and start the engine. Verify that the speedometer needle moves smoothly and accurately reflects vehicle speed. Check for any abnormal vibrations or noise from the cable.

Maintenance Tips

• Inspect the cable periodically for signs of wear, such as frayed insulation or exposed conductors.
• Avoid sharp bends that could compromise the internal wiring; maintain a gentle curvature when routing.
• If the speedometer display becomes erratic, consider replacing the shaft to rule out signal loss due to cable degradation.
