60526 - 2007-2012 GM Gen IV 4.8-6.2L EFI Harness - Throttle by Wire
This harness is designed for use on any 2007-2012 4.8L, 5.3L, 6.0L, & 6.2L Vortec truck engines with throttle by wire. It uses the factory ECM & TCM and will operate engines with or without variable valve timing (VVT) and active fuel management (displacement on demand or DOD). This harness does not support flex fuel operation. Included with this harness is a 10 circuit weatherproof fuse block & mounting bracket, GM color coded wires with labels, and all the required terminals and connectors 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 harness also requires the following mating parts; ECM #12597121 (Painless # 60701) or #12612384 (Painless # 60702); TCM #24234503(Painless # 60710); Accelerator Pedal #25832864 or #25835421.
We recommend checking the online manual for the full list of required mating parts prior to ordering.
