 GM LS-1 Fuel Injection Harnesses

1997-2002 Corvette and 1998-2002 Camaro/Firebird LS-1: First introduced in the 1997 Corvette and then available in the 1998 Camaro and Firebird, this is GM's generation III small block engine design. All aluminum block and heads, six bolt main caps, and individual ignition coils for each cylinder are just a few of the new designs implemented on this engine.

While the Camaro/Firebird and Corvette engines are similar, the Corvette version is impractical to install in an aftermarket application. While still listed as 4L60-E (automatic) transmission (also available in manual), the transmission was moved back to the rear of the vehicle and labeled a transaxle. The Camaro/Firebird engine version transmission still bolts direct to the engine block and is labeled a 4L60-E. The Corvette version of this engine utilizes an electric motor mounted on the throttle body utilizing various sensor inputs to control engine RPM (acceleration). Aftermarket applications require conversion to a 1998 Camaro throttle body for accelerator cable control. Cable driven speedometers use of older type transmissions (4L60, 700 R4, Turbo 350) cannot be used with this engine.

If you plan to use the Corvette engine version, it is best that it be wired as Camaro/Firebird. The engine computer for the 1998 Corvette and Camaro/Firebird are the same part number, however the Corvette computer must be reprogrammed to utilize the Camaro/Firebird programming. This engine utilizes the OBD II diagnostic system and requires "all" emission control devices be connected into the system or trouble codes will be set. Make it run like factory.

1999-Newer GM Truck LS-1 4.8, 5.3 & 6.0: These are coil on plug based LS-1 engines but in iron block form.  Found in most Chevy and GM trucks and SUV's (Suburbans, Tahoes, Yukons, etc.)  Due to the complex anti-theft found in these computers, we do need to reprogram your ECM. We can provide a host of other services on the ECM including removing all the emissions. Click on the link below for more info.
