Take advantage of GM's electronic engine management system with this Painless Wiring Harness. Complete stand alone harness allows you to install late model GM fuel injected engine and correct computer into almost any chassis. Harness includes all needed connections for fuel injection operation: ECM, MAP, O2, TPS, ESC, IAC, IAT, CTS, Knock, Injectors, OBD1 w/SES light, VSS and TCC solenoid.
This standard length harness allows four 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 or behind the dash or glove box.
Besides the obvious economy and driveability benefits, check out these other great features that make it easy and painless to install:
- Foolproof factory connections
- ALDL (diagnostic) plug
- Computer controlled fuel pump provision
- Wired for 2004R or 700R4 transmission and EGR solenoid
- GM color code
- Closed loop design
1990-1992 GM TPI Wiring Instructions (PDF)
For installations of 1990 - 1992 Tuned Port Injection 5.0L and 5.7L V8 engines using the MAP system. These engines were factory equipped in Chevrolet Camaro and Corvette and were mated to either a 200-4R or 700-R4 transmission.
Note: The 1986-1989 TPI uses a Mass Air Flow Sensor, and is easier to use on a hot rodded motor. This 1990-1992 unit uses a MAP sensor, which works best on a stock or very mild motor.
This kit includes:
- All new fuel injection harness with OEM fitment connectors and harness breakouts
- OBD I connector, mounting bracket and check engine light
- Crimp on terminals and rubber grommet
- Mounting hardware
- Installation manual
