Standalone Wiring Harness for Drive-by-Wire LH6/LY5/LMG/LH8 - '96-'07 13-pin

This Standalone Wiring Harness for Drive-by-Wire LH6/LY5/LMG/LH8 - '96-'07 13-pin is built for standalone Drive-by-Wire engine management with transmission configuration shown in the title. The harness 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/LT engine control installation.

Use this harness when the engine code, throttle type, transmission connector, ECU strategy, and sensor layout match the compatibility section. The EV6 injector plug style should be matched to the engine and injector set. Confirm transmission pin count, pedal and throttle body requirements, oxygen sensor layout, MAP/MAF connections, and power/ground routing before installation.

What does the "'96–'07" in the title refer to?
The "'96–'07" designation refers to the 13-pin connector used on certain 4L60E automatic transmissions commonly found in 1996–2007 GM vehicles. It does not refer to the engine model years. This harness is designed for 2009–2014 GM 5.3L LH6, LY5, LMG, and LH8 engines.

What engines and transmission is this harness compatible with?
This standalone wiring harness is designed for 2009–2014 GM 5.3L LH6, LY5, LMG, and LH8 Gen IV LS engines paired with a 4L60E automatic transmission using the earlier 13-pin transmission connector.

How is this different from TSP's other LH6/LY5/LMG/LH8 harnesses?
This harness is one of four transmission connector variants available for these engines. It is specifically designed for 4L60E transmissions equipped with the 13-pin connector. Before ordering, verify whether your transmission uses an 11-pin, 13-pin, 15-pin, or 17-pin connector, as these harnesses are not interchangeable.

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

Does this include a PCM/ECM, throttle body, or accelerator pedal?
No. This harness does not include a PCM/ECM, throttle body, or accelerator pedal. These components must be purchased separately and matched to your engine and application.

What's included in this harness kit?
This harness includes wiring for the fuse/relay box, fuel pump control, electric fan controls, check engine light, speedometer, tachometer, OBD2 diagnostic port, accelerator pedal and throttle body control, MAF sensor, MAP sensor, engine coolant temperature sensor, alternator control, two upstream oxygen sensors, crankshaft position sensor, camshaft position sensor, fuel injectors, coil packs, transmission control, and knock sensors.

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