Installation Notes and Tips

Verify engine and emission-system fitment before ordering, especially on 1990-1991 Ford LTD Crown Victoria and 1991 Mercury Colony Park or Grand Marquis models with Federal Emission System. Route the wires to match the original layout, keep them away from hot exhaust components, and confirm each terminal is fully seated on the spark plug and ignition coil connections.
