Product Description
Michigan Motorsports LS2 LS3 LS7 LQ4 LQ9 Ignition Coil 48" Harness Extension
48" One-Piece Coil Relocation Harness | Fits D585, D514A, D581 & D510C Ignition Coils
Remote mount your LS ignition coils with the Michigan Motorsports LS2 LS3 LS7 LQ4 LQ9 Ignition Coil 48" Harness Extension. This harness set is designed for coil relocation setups using compatible D585, D514A, D581, and D510C ignition coils. The 48" one-piece design eliminates the need to patch together a separate bracket harness and extension harness, giving your relocation a cleaner look with fewer connection points. Ideal for LS coil relocation brackets, LS swaps, custom valve cover setups, shaved engine bays, and performance builds, this new harness gives you the extra length needed to move coils to a remote mounting location while keeping the wiring organized and serviceable.
Key Features & Benefits
- 48" Coil Relocation Harness: The extended 48" length gives you the reach needed to remote mount LS ignition coils away from the factory valve cover location. This is ideal for custom coil bracket placement on the firewall, frame rail, inner fender, or other suitable mounting locations.
- One-Piece Harness Design: This harness eliminates the need to combine a bracket harness with a separate extension harness. Fewer connection points help create a cleaner install, reduce wiring clutter, and give the finished coil relocation setup a more professional appearance.
- Fits Multiple LS Coil Styles: Designed for compatible D585, D514A, D581, and D510C ignition coils. Check the ignition coil guide in the product photos before ordering to confirm your coil style matches this harness.
- Great for LS Engine Bay Cleanup: Perfect for LS2, LS3, LS7, LQ4, LQ9, and related LS coil relocation projects where removing coils from the valve covers creates a cleaner look. This harness works well with custom valve covers, swap builds, and performance engine bays.
- New Harness for a Cleaner Relocation: Using a new dedicated relocation harness helps avoid patched-together wiring and gives you more confidence in the finished installation. It is a practical wiring solution for remote coil mounting and LS ignition system organization.
