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.
Designed for use on the 1999-2006 4.8L, 5.3L, 6.0L throttle by wire engines with a 4L60E, 4L65E, 4L70E, 4L80E, 4L85E, or manual transmission.
These engines were found in factory 2003-2006 Vortex Trucks.
Installing a 2003-2006 TBW throttle body will be required for 1999-2002 engines.
Supported engine codes are LR4, LM7, LM4, LQ4 and LQ9.
This harness will support flex fuel and non-flex fuel engines.
An inline fuel composition sensor will be required for flex fuel engines to run E85 fuel.
Included with this harness is a 10-circuit weatherproof fuse block mounting bracket and GM color coded wires with labels for easy installation.
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.
Includes: all new fuel injection harness with OEM fitment connectors and harness breakouts, OBDII connector, mounting bracket and check engine light, crimp-on terminals, rubber grommet and mounting hardware.
