4L80E Transmission Control Harness

The AMP EFI LS 4L80E Transmission Control Harness is a plug-and-play subharness designed to simplify the connection between your GM 4L80E automatic transmission and a MicroSquirt transmission controller. This harness is ideal for LS swap builders, racers, and tuners who already possess a MicroSquirt TCU, offering a quick, reliable installation process without the need for cutting or splicing. Engineered to integrate seamlessly, this harness is the same component found in AMP EFI's full 4L60E TCU kit and is designed to plug directly into AMP EFI's LS 24x and 58x PNP Engine Harnesses. It features OEM-style connectors for a secure and easy fit, supports CAN communication with various MicroSquirt ECUs, and includes wiring for the input shaft speed sensor. The construction utilizes automotive-grade materials and loom for enhanced reliability. This harness is compatible with GM 4L80E automatic transmissions featuring the 1994 and newer style connector, as well as MicroSquirt-based transmission controllers, MS3Pro setups via CAN bus, and standalone TCU wiring setups. It is crucial to note that this harness is not compatible with early 1993 or older 4L80E transmissions that use the original-style connector. The listing is for the harness only; no MicroSquirt controller is included.
