HRNS GM LS2/3/7 BY WIRE 0608

This Painless Performance 60524 Standard Length EFI Wiring Harness is designed for use on any 2008 and up LS3 engine with throttle by wire. It utilizes the factory ECM and TCM and is compatible with engines that have or do not have variable valve timing (VVT) and active fuel management (displacement on demand or DOD). This harness does not support flex fuel operation. Included with the harness are a 10-circuit weatherproof fuse block with mounting bracket, GM color-coded wires with labels, and all necessary terminals and connectors for straightforward installation. Its standard length allows for a four-foot distance from the rear of the intake manifold to the fuse block and ECM mounting locations, making it suitable for installations under the dash or in the glove box.
