This standalone harness is not intended to replace the OEM engine wiring.
Intended for running the designated engine & transmission only, standalone harnesses are generally used when swapped into another vehicle.
Designed 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 original connections for the original emissions but are available separately; see the specs page for more details.
A detailed step-by-step manual is also available for this harness, along with GM color-coded wires with labels for easy installation.
This harness allows eight feet from the back of the intake manifold to where the fuse block and ECM mount.
For those planning to mount these components under the seat or in the center console, this extended length harness is suitable.
The following mating parts are required for this harness: ECM #1227730, #16198262, or #88999196.
The EPROM broadcast code must match tire diameter, gear ratio, engine size, and transmission.
Checking the online manual for the full list of required mating parts prior to ordering is recommended.
