Painless 60102 GM TPi Fuel Injection Wiring Harness for 5.0L and 5.7L engines from 1986-1988. Designed for those who choose to run the factory engine management computer when swapping engines. You will appreciate the simplicity of a Painless Performance fuel injection wiring harness! Yes, you can whittle away at the stock wiring hraness and eventually make it work, but why complicate your life? Why work with wire and connectors that have already aged by many years? The Painless Performance engineers have worked out all the potential problems ahead of time so all you have to do is follow the detailed instructions and you're on your way. Every wire is color coded and labeled for ease of installation. Painless, the professional way to wire! The GM Tuned Port Fuel Injection system this Painless wiring harness operates is a perfect upgrade for those fed up with their carburetor fueled engine. Works great for street rods and customs where a longer harness will help the installation. This harness utilizes factory components listed here. Designed for installation of 1986-1989 TPi 5.0L, 5.7L engines using the Mass Air Flow system. Includes all needed connections for fuel injection operation, such as: ECM, MAF, O2, TPS, ESC, IAC, IAT, CTS, knock, injectors, OBD1 with SES light, VSS and TCC solenoid. This extra 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 or behind the passenger seat. THIS KIT INCLUDES: All new fuel injection harness with OEM fitment connectors and harness breakouts. OBD1 connector, mounting bracket and check engine light. Crimp on terminals and rubber grommet. Mounting hardware and installation manual.
