Installation Guide

1. Disconnect the Battery: Ensure safety by removing the negative terminal before working on electrical components.
2. Remove the Old Unit: Locate the existing ignition module, usually mounted near the engine block or under the dashboard. Disconnect wiring harnesses and unscrew mounting brackets.
3. Mount the V24‑70‑0026: Align the new unit with the mounting holes and secure it using the supplied screws. Verify that the connector aligns correctly to avoid reverse polarity.
4. Reconnect Wiring: Attach the shielded harness, ensuring all pins match their respective contacts. Tighten connectors firmly but do not overtighten to prevent damage.
5. Re‑connect the Battery: Restore power and check for any error codes on the vehicle’s diagnostic display.
6. Test Run: Start the engine and observe smooth operation. Listen for consistent spark and monitor engine performance parameters such as idle stability and throttle response.
