Painless TPI Harness (MAP)
This harness is 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 the original connections for the original emissions but are available separately. Also available for this harness is detailed step-by-step manual, and GM color coded wires with labels for easy installation.
This extended length harness allows eight feet from the back of the intake manifold to where the fuseblock and ECM mount. Perfect for those that plan to mount these components under the seat or in the center console. 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.
This harness is standalone and is not intended to replace the OEM engine wiring. Standalone harnesses are intended to run the designated engine & transmission only, generally when swapped into another vehicle.
