NotesThis harness is designed for use on the 1999-2006 throttle by wire engines with a 4L60E, 4L65E, 4L70E, 4L80E, 4L85E, or manual transmission. 1999-2002 engines will require installing a 2003-2006 throttle by wire throttle body. This harness will support flex fuel and non flex fuel engines. Flex fuel engines will require an inline fuel composition sensor in order 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.
Special AttentionThis is not an OEM replacement harness. This harness is standalone and is not intended to replace the OEM engine wiring. Standalone harnesses are intended to run the designated engine and transmission only, generally when swapped into another vehicle.
