Painless Wiring LS Engine Ignition Coil Extension Harness Kit

Painless Performance LS Engine Ignition Coil Extension Harness Kits are purpose-built solutions for LS engine swaps, custom builds, and modified vehicle installations that require ignition coil relocation. Each kit provides the flexibility to move coils off the valve covers and reposition them to the firewall or other mounting locations, all while maintaining clean, reliable signal delivery throughout the ignition system.

Key Features:

• Factory Color-Coded Wiring: Manufactured with factory color-coded wires for straightforward, mistake-free installation and easy future serviceability
• Weatherproof Connectors: Pre-terminated weatherproof connectors seal out moisture and contaminants, ensuring long-term reliability in demanding under-hood environments
• Automotive-Grade TXL Wire: Built with high-grade TXL wire featuring cross-linked polyethylene insulation, offering superior heat resistance, abrasion resistance, and durability compared to standard PVC wire
• Plug-and-Play Design: Pre-terminated connectors on both ends eliminate splicing, cutting, or custom modifications — connect directly to the factory coil harness and go
• Driver and Passenger Side Coverage: Each kit includes one driver side and one passenger side pigtail, providing a complete solution for both coil banks
• Multiple Length Options: Available in a range of pigtail lengths to suit different swap configurations, chassis layouts, and coil mounting locations
• Rigorous Quality Control: Every crimp, splice, and terminal connection is inspected throughout production to ensure the integrity of the finished harness
