Description

Standalone Wiring Harness for Drive-by-Wire LH6/LY5/LMG/LH8 - '09 17-pin

This harness is built for standalone Drive-by-Wire engine management with a 4L60E automatic transmission (2009-and-later, 17-pin connector). 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.

NOTES
• Standalone drive-by-wire engine management harness designed for LS engine swap and custom build applications — not a factory replacement harness.
• Injector plug style: EV6 — confirm injector connector style before ordering.
• Includes: fuse/relay box, fuel pump control, fan controls, check engine light, speedometer, tachometer, OBD2, accelerator pedal and throttle body control, MAF sensor, MAP sensor, engine coolant temp sensor, alternator control, (2) upstream oxygen sensors, crankshaft position, camshaft position, fuel injectors, coil packs, transmission control, and knock sensors.
• Confirm transmission pin count, pedal and throttle body requirements, oxygen sensor layout, MAP/MAF connections, and power/ground routing before installation.
• ECU and tuning required separately — harness does not include PCM.

Q&A

What does the "'09" and "17-pin" in the title refer to?
The "'09" refers to the 2009–2014 engine applications, while "17-pin" identifies the 17-pin connector used on certain 4L60E automatic transmissions. This harness is specifically designed for 2009–2014 5.3L LH6, LY5, LMG and 6.0L LH8 engines paired with a 17-pin 4L60E transmission.

What engines and transmission is this harness compatible with?
This standalone wiring harness is compatible with 2009–2014 GM Gen IV 5.3L LH6, LY5, and LMG engines, as well as the 6.0L LH8 engine, when used with a 4L60E automatic transmission equipped with the 17-pin connector.

How is this different from TSP's other LH6/LY5/LMG/LH8 harnesses?
This is one of four transmission connector variants of the same engine wiring harness. Verify whether your transmission uses a 13-pin 4L60E, 11-pin 4L80E, 15-pin 4L60E, or 17-pin 4L60E connector, as these harnesses are not interchangeable.

What injector connector style does this harness use?
This harness uses EV6-style fuel injector connectors.

Does this include a PCM/ECM, throttle body, or accelerator pedal?
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. The throttle body and accelerator pedal are also not included and must be purchased separately.

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.
