  • App
  • Specs

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.  

 

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 orginal connections for the the orginal emissions but are available separate, 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 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.

We recommend checking the online manual for the full list of required mating parts prior to ordering.

#60315- In states/counties which require all the original emission equipment to be installed, Painless offers this emission harness for the 60203 harness. This harness activates the Air Port solenoid Control, Air Diverter Solenoid and Canister Purge Solenoid.


If you plan to mount the ECM under or behind the dash or in the glove box please see Painless Performance®™ part number 60103 as it provides 4 feet of harness length between the main engine breakout and the ECM connectors.


Installs which have an external coil distributor:
#60124- This pigtail will be required in order to connect the coil to the distributor.
#60125- This pigtail will be required in order to connect the power to the coil and will provide a tach signal from the coil.
