This standalone harness is not intended to replace the OEM engine wiring.
Standalone harnesses are designed to run the designated engine and transmission only, generally when swapped into another vehicle.
This harness is for the throttle by wire LS1/LS6 engines from 1997-2004 with a 4L60E/4L65E automatic or T56 manual transmission.
These engines were factory equipped in the Corvette from 1997-2004.
Harnesses do not include any emissions-related connections.
An 8-circuit modular fuse block and GM color-coded wires with labels for easy installation are included with this harness.
This standard length harness allows four feet from the back of the intake manifold to where the fuse block and ECM mount, perfect for those planning to mount these components under the dash or in the glove box.
This kit includes: all new fuel injection harness with OEM fitment connectors and harness breakouts, OBDII connector, mounting bracket, and check engine light, rubber grommet, and mounting hardware.
This harness also requires the following mating parts: ECM #12200411, TAC Module #12578953, Accelerator Pedal #12565643.
PLEASE NOTE: GM no longer offers the accelerator pedal #12565643.
The sensor is still available; however, the full assembly is not.
Sourcing a pedal before proceeding with your project is recommended.
Trying a certified used parts supplier is suggested.
Checking the online manual for the full list of required mating parts prior to ordering is recommended.
