This harness is standalone and is not intended to replace the OEM engine wiring.
Standalone harnesses are designed to run the designated engine & transmission only, generally when swapped into another vehicle.
This harness is for 1990-1992 Tuned Port Injected TPI 5.0L /5.7L V8 engines using the MAP speed density system.
These engines were factory equipped in Chevrolet Camaro and Corvette and were mated to either a 200-4R or 700R4 transmission.
Harnesses do not include all the original connections for the original emissions but are available separately; see the specs page for more details.
Also available for this harness is a detailed step-by-step manual, and GM color coded wires with labels for easy installation.
This harness also requires the following mating parts: ECM #1227730, #16198262, or #88999196.
The EPROM broadcast code must match tire diameter, gear ratio, engine size, and transmission.
It is recommended to check the online manual for the full list of required mating parts prior to ordering.
