Fits 1992-1997 LT1/LT4 5.7L & L99 4.3L (V8) with a 4L60E transmission, using a 1994-1997 ECM. This harness will NOT work with 1992-1993 ECMs. These engines and transmissions were factory equipped in Camaro, Firebird, Corvette, Roadmaster, Impala and Caprice. Harness includes all connections needed for fuel injection and transmission operation: ECM, Ignition Module, IAT, CTS, Coil, Left & Right O2, EGR, MAP, IAC, Knock, Air Pump Relay, MAF, Fuel Pump Relay, Canister Purge Solenoid, VSS and 4L60E Transmission. Harness includes its own fuse block with ignition relays. 4 feet of harness between ECM connections and main engine breakout gives ample room for custom installation and mounting of ECM behind dash, in the kick panel or glove box.
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 1996 or 1997 engine you must replace the coil, coil output wire and knock sensor with the parts from a 1992-1995 engine. Included with this harness is an 8 circuit modular fuse block and GM color coded wires with labels for easy installation.
