    EFI Wiring Harness

  • 1986-93 GM 4.3/5.0/5.7/7.4L TBI

    The GM Throttle Body Injection system this Painless Performance harness operates is a perfect upgrade for those fed up with their carburetor fueled engine. Harness utilizes factory components listed in the next paragraph or see the actual part numbers in the installation manual. This harness will not work with a 94 or 95 ECM and will NOT operate a 4L60e transmission.

    For installations of 1986-1993 4.3L, 5.0L, 5.7L, 7.4L Throttle Body Injection and Cross Fire engines (with a 200-4R, 700-R4 of other non-electronic transmission). Harness includes all 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 fuse block and ECM mount. Perfect for those that plan to mount these components under the dash or in the glove box.
