Description

Standalone Wiring Harness for Drive-by-Wire LY6/L92 with Automatic Transmission - 11 pin

This harness is built for standalone Drive-by-Wire engine management with a 4L80E automatic transmission (11-pin). It integrates the fuse/relay box, sensor connectors, engine control wiring, fuel pump control, fan control, OBD2 connection, and supporting outputs needed for a clean LS engine control installation.

Use this harness when the engine code, throttle type, transmission connector, ECU strategy, and sensor layout match the compatibility section. This harness uses an EV6-style injector plug — confirm your engine's injectors use this style before ordering. Confirm transmission pin count, pedal and throttle body requirements, oxygen sensor layout, MAP/MAF connections, and power/ground routing before installation.

Q&A

What applications is this wiring harness compatible with?
This standalone wiring harness is designed for 2009–2014 GM Gen IV drive-by-wire LY6 6.0L and L92 6.2L truck engines when paired with a 4L80E automatic transmission equipped with the 11-pin connector.

Does this include a PCM/ECM?
No. This is a standalone engine wiring harness and does not include a PCM/ECM. A compatible PCM/ECM programmed for your specific engine and transmission combination is required.

What injector connector style does this harness use?
This harness uses EV6-style fuel injector connectors. Verify your engine is equipped with EV6 injectors before ordering.

What's the difference between the LY6 and L92 engines?
The LY6 is a 6.0L Gen IV truck engine, while the L92 is a 6.2L Gen IV truck engine. This wiring harness is compatible with both engine codes.

How is this different from TSP's other LY6/L92 harness?
This version is designed for a 4L80E automatic transmission equipped with the 11-pin connector. TSP also offers a version for 4L80E transmissions with the 13-pin connector. Verify whether your transmission uses an 11-pin or 13-pin 4L80E connector before ordering, as these harnesses are not interchangeable.

Does this include the throttle body or accelerator pedal?
No. The throttle body and accelerator pedal are not included and must be purchased separately. The harness includes the necessary wiring for electronic throttle body and accelerator pedal control.

What's included in this harness kit?
This harness includes a fuse/relay box, fuel pump control wiring, electric fan controls, check engine light wiring, speedometer and tachometer outputs, OBD2 diagnostic connector, electronic throttle body and accelerator pedal wiring, MAF and MAP sensor wiring, coolant temperature sensor wiring, alternator wiring, upstream oxygen sensor wiring, crankshaft and camshaft position sensor wiring, EV6 fuel injector connectors, coil pack wiring, transmission control wiring, and knock sensor wiring. Fuel injectors are not included.

Does this include installation instructions?
Yes. A downloadable installation instruction sheet is available for this harness.
