Product Description:
Restore proper engine management and electrical system functionality with this genuine OEM GM Engine Wiring Harness for 2005-2006 Pontiac GTO models. This used factory harness has been removed from an original vehicle and is designed to provide the correct connections between the engine, sensors, fuel system, ignition components, and vehicle electronics.
Whether you're replacing a damaged harness, repairing electrical issues, or completing an LS2 engine swap using factory components, an OEM GM engine harness ensures proper fitment and connector compatibility that aftermarket alternatives may not provide.
All harnesses are inspected for major damage prior to sale. As a used OEM component, minor cosmetic wear, dirt, tape imperfections, or previous service markings may be present.
