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 1992-1997 5. 7L LT1/LT4 & 4. 3L (V8) L99 engines with a 4L60E transmission, using a '94-'97 ECM. This harness will not work with ’92-’93 ECMs. These engines and transmissions were factory equipped in Camaro, Firebird, Corvette, Road master, Impala and Caprice. These harnesses also include a VATS bypass module. The 4L60E transmission used must be a 1994+ which utilizes a 13th pin on the transmission connector. When using either of these harnesses on a '96 or '97 engine you must replace the coil, coil output wire and knock sensor with the parts from a '92 -'95 engine. Included with this harness is an 8-circuit modular fuse block 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 fuse block and ECM mount. . . perfect for those that plan to mount these components under the seat or in the center console. This kit includes: All new fuel injection harness with OEM fitment connectors and harness breakouts; OBDII connector, mounting bracket and check engine light; Vehicle Anti Theft System (VATS) bypass module; Rubber grommet and mounting hardware, Installation manual. This harness also requires the following mating parts; ECM #16188051 or #88961150. We recommend checking the online manual for the full list of required mating parts prior to ordering.

  • Painless fuel injection wiring utilizes all new TXL wire, OEM fitment connectors and grouped harness breakouts making for an easy install and saving you from using old re-worked wiring; Machine crimped terminals match OE quality
  • Every EFI harness is tested before leaving our facility, ensuring that each connector is properly pinned out and seated…no chasing mis-pinned connections with Painless EFI wiring
  • Diagnostic port and check engine light included with powder coated bracket, allowing you to check codes and troubleshoot just like a new OE vehicle; See product details below for additional fitment information
