OEM-Style 3-Pin K-Series Ignition Coil Connector – Professional Harness Grade

The Honda K-Series 3-Pin Coil Pack Connector Kit is an OEM-style ignition connector designed for K20 and K24 coil-on-plug applications. These connectors fit factory Honda K-Series ignition coils and are ideal for engine harness repair, K-swap builds, standalone ECU installations, and custom coil harness fabrication.

These are the same high-quality connector housings and terminal sets used in-house at VTEC Innovations for professional harness construction.

Designed for K20 & K24 Ignition Systems

This 3-pin coil connector is used on:

• Honda K20 engines

• Honda K24 engines

• RSX Type-S

• 8th Gen Civic Si

• TSX K24A2

• K-swap builds

• Standalone ECU conversions

Perfect for replacing damaged coil connectors or building new ignition harness systems from scratch.

Perfect for standalone ECU installations using Haltech, FuelTech, or MoTeC systems. Pair with our Standalone ECU Connector Kits for complete custom harness construction.

Ideal for Custom Coil Kits & Harness Repairs

These connectors are commonly used for:

• Custom coil harness builds

• K-swap engine harness fabrication

• Coil-on-plug conversions

• Ignition system repairs

• Motorsport and race harness construction

Proper ignition wiring is critical for consistent spark energy and engine reliability.

When building a complete K-swap harness, combine these coil connectors with our Honda K-Series sensor connectors for crank, cam, MAP, and VTEC circuits.

Built for Professional Harness Fabrication

• Accepts 22–20 AWG terminals

• Includes matched wire seals

• OEM-style locking housing

• Designed to withstand engine bay heat and vibration

• High-quality connector system used by VTI in production harness builds

These are not generic low-grade connectors — they are selected for professional engine harness construction.

For professional ignition signal routing, we recommend using MIL-DTL-27500 Spec 55 shielded cable for crank and cam circuits in high-performance K-series builds.

Available Configurations
