It is specified for external installation and uses a blade-style terminal layout to match the original electrical connection on the listed Mazda MPV, Mercury Capri, and Mazda B2600 applications. This part number, LX-644, is a direct-fit service option for vehicles requiring the same module style and connector configuration.

Common Problems This Module Can Address

• Engine no-start caused by ignition module failure
• Intermittent stalling related to ignition signal loss
• Misfire conditions from weak or inconsistent spark control

• Loss of ignition output on supported Mazda and Mercury applications

Installation Notes and Tips

Verify the original connector style, terminal count, and mounting style before installation. The LX-644 mounts externally with a bolt-on design and uses male blade terminals, so the harness and mounting surface must match the OE configuration. No instructions are included, so compare the removed module to the replacement part before final assembly.
