Description

GM Standalone '97-'04 LS1 and LS6 Drive by Wire Corvettes with 4L60E Transmission Wiring Harness

This GM Standalone '97-'04 LS1 and LS6 Drive by Wire Corvettes with 4L60E Transmission Wiring Harness is built for standalone Drive-by-Wire engine management with 4L60E automatic 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 EV1 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.
