Description
Standalone Wiring Harness for Drive-by-Wire LH6/LY5/LMG/LH8 - 11 pin
This Standalone Wiring Harness for Drive-by-Wire LH6/LY5/LMG/LH8 - 11 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.

COMPATIBLE WITH
'09-14 Trucks Drive-by-Wire LH6/LY5/LMG/LH8 Engines
• WH1213: 4L60E ('96-'07 13-pin) automatic transmission
• WH1213-1: 4L80E (11-pin) automatic transmission
• WH1213-2: 4L60E ('05-'08 15-pin) automatic transmission
• WH1213-3: 4L60E ('09+ 17-pin) automatic transmission
NOTES
• Standalone harness — requires a compatible PCM/ECM matched to your engine code.
• This is one of four transmission-connector variants of this same engine harness — confirm your specific transmission's connector pin count (13-pin 4L60E, 11-pin 4L80E, 15-pin 4L60E, or 17-pin 4L60E) before ordering, as WH1213, WH1213-1, WH1213-2, and WH1213-3 are not interchangeable.
• Does not include a PCM/ECM, throttle body, or accelerator pedal — confirm these separately before ordering.
COMMON VEHICLE APPLICATIONS
- Chevrolet Silverado / GMC Sierra (2009–2013, 5.3L LH6/LY5/LMG/LH8)
- Chevrolet Tahoe/Suburban, GMC Yukon/Yukon XL (2009–2014, 5.3L LH6/LY5/LMG/LH8)
- Cadillac Escalade (2009–2014, where equipped with a 5.3L variant)
- LS/LT engine swap applications pairing a 2009-2014-generation 5.3L truck engine with an 11-pin 4L80E transmission
Q&A
What does the 11-pin designation refer to?
The 11-pin designation refers to the connector used on certain 4L80E automatic transmissions. This harness is specifically designed for applications using a 4L80E transmission equipped with an 11-pin transmission connector.
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 4L80E automatic transmission using the 11-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 4L80E transmissions equipped with the 11-pin connector. Before ordering, 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. 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.
