Overview

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.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
