The M63_P3 Output Harness is designed to connect Spitronics engine management systems to various external output devices such as solenoids, relays, actuators, or control circuits. It ensures stable signal transmission from the ECU, allowing precise control of assigned outputs required for correct engine operation and auxiliary system management.

Manufactured using automotive-grade wiring and durable connectors, the harness is engineered to perform reliably in demanding engine bay conditions, including exposure to heat, vibration, and electrical interference. Its plug-and-play configuration simplifies installation, reduces wiring complexity, and provides a clean, professional solution suitable for both workshop installations and custom performance applications.
