This harness is not intended as an OEM replacement but is specifically designed to manage engine and transmission functions in non-factory setups.

Key Features:

• Engine Compatibility: Designed for use with 1992-1997 5.7L LT1/LT4 and 4.3L (V8) L99 engines. Ideal for projects utilizing a 4L60E transmission with a '94-'97 ECM. Note that this harness will not work with '92-'93 ECMs.
