Painless Wiring 60524 Throttle By Wire EFI Harness 08+ Gen IV LS3

This harness is designed for use on any 2008 and up LS3 with throttle by wire. It uses the factory ECM And 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 And 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.
