The E75_P4 TCU Output Input Harness is designed to connect a compatible Spitronics Transmission Control Unit (TCU) to both transmission-related input signals and external output devices through a single harness. This integrated design supports reliable signal exchange for inputs such as switches or sensors, as well as outputs to solenoids, actuators, or control circuits required for proper transmission operation.

Constructed using high-quality automotive-grade wiring and durable connectors, the harness is engineered to perform reliably in demanding automotive environments, including heat, vibration, and electrical interference. Its plug-and-play configuration simplifies installation, reduces wiring complexity, and provides a clean, professional solution for efficient and organised TCU installations in both standard and custom vehicle applications.
