Painless Wiring 60221 - 2003-2006GM Gen III 4.8, 5.3 & 6.0L Throttle by Wire Harness Std. Length

This harness is designed for use on the 2003-2006 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 Vortec Trucks. 1999-2002 engines will require installing a 2003-2006 TBW throttle body. Engine codes supported are LR4, LM7, LM4, LQ4 and LQ9. 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. This standard length harness allows four feet from the back of the intake manifold to where the fuseblock and ECM mount. Perfect for those that plan to mount these components under the dash or in the glove box. This kit 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 Mounting hardware We recommend checking the online manual for the full list of required mating parts prior to ordering.
