Description
GM Standalone LY6, L92 Drive by Wire Engine and Standard Trans Wiring Harness
This GM Standalone LY6, L92 Drive by Wire Engine and Standard Trans Wiring Harness is built for standalone Drive-by-Wire engine management with standard transmission. 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.

Engine Fitment
COMPATIBLE WITH
'09-14 Trucks*
*Fits drive-by-wire applications with LY6 and L92 engines and T56/TR6060 manual or non-electronic automatic (700R4, 200-4R, Powerglide, TH350, TH400) transmissions
NOTES
Standalone harness — requires a compatible PCM/ECM matched to your engine code.
Fits 2009-2014 production connector generation for LY6 (6.0L) and L92 (6.2L) engines — earlier (2007-2008) L92/LY6-equipped vehicles use a different harness connector generation and are not covered by this harness.
Does not include a PCM/ECM, throttle body, or accelerator pedal — confirm these separately before ordering.
COMMON VEHICLE APPLICATIONS
- Chevrolet Silverado / GMC Sierra HD (2009–2014, 6.0L LY6)
- Cadillac Escalade / Escalade ESV / EXT (2009–2014, 6.2L L92-family)
- GMC Yukon Denali / Yukon XL Denali (2009–2014, 6.2L L92-family)
- Chevrolet Tahoe/Suburban (2009–2014, where equipped)
- LS/LT engine swap applications using a 2009-2014-generation LY6 or L92 engine paired with a T56/TR6060 manual or non-electronic automatic transmission
Q&A
What engines and transmissions is this harness compatible with?
This standalone wiring harness is designed for 2009–2014 GM 6.0L LY6 and 6.2L L92 Gen IV LS engines paired with a T56 or TR6060 manual transmission, or a non-electronically controlled automatic transmission, including the 700R4, 200-4R, Powerglide, TH350, and TH400.
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?
No. This is a standalone engine wiring harness and does not include a PCM/ECM. A compatible PCM/ECM programmed for your specific engine combination is required.
Does this include the throttle body or accelerator pedal?
No. The throttle body and accelerator pedal are not included and must be purchased separately.
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.
