Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- 2003-2007 Chevrolet and GMC truck-based Gen III 4.8L, 5.3L and 6.0L engines with 24X crank and drive-by-wire
- Compatible Cadillac and Hummer truck-engine donors using the same ECU, sensors, throttle system and injector connectors
- 4L60E / 4L65E / 4L70E applications where the supplied transmission connector and calibration match
Product Overview
An LS swap needs a clean way to connect the engine, transmission, electronic throttle, sensors, power, grounds, relays, and ECU outside the donor truck. This standalone harness removes unrelated body wiring and provides labeled branches for a compatible drive-by-wire powertrain.
LS parts interchange physically more often than they interchange electrically. Confirm 24X crank signal, ECU connector, cam sensor location, electronic throttle type, pedal and TAC requirements, injector plug, alternator, oxygen sensors, transmission, and emissions needs. A 4L80E or manual setup may require changes.

- Standalone engine and transmission harness for compatible swaps
- Drive-by-wire throttle-system connections
