Honda K-Swap Universal Chassis Subharness

Honda K-Swap Universal Chassis Subharness

This universal K-swap chassis subharness is designed to interface K-Series engine wiring harnesses with custom or simplified chassis wiring. It provides a clean and flexible solution for K-series swaps where a chassis-specific subharness is not required or where factory under-dash wiring has been modified or removed.

This subharness is ideal for custom builds, race cars, and projects that require adaptable routing rather than fixed OEM chassis integration.

Universal Integration for K-Series Swaps

This subharness supports universal K-swap applications by allowing critical engine and ECU-related signals to be cleanly interfaced with the vehicle’s power, ignition, and chassis circuits.

Rather than relying on chassis-specific connectors, this design allows flexible routing and termination while maintaining proper signal integrity for K-Series engine operation.

ECU Compatibility Options

This universal K-swap subharness is available with selectable ECU compatibility to support different K-Series engine management setups.

Hondata KPro compatibility supports common K-Series swap configurations using KPro engine management.

K-Tuner 05–06 ECU compatibility supports applications using 2005–2006 K-Series ECUs running K-Tuner software.

ECU selection is made at checkout to ensure proper wiring configuration for your chosen engine management system.

High-Quality TXL Construction

This universal K-swap subharness is built using high-quality TXL automotive-grade wire and OEM-style connectors to ensure long-term reliability, heat resistance, and flexibility.

TXL wiring offers an excellent balance of durability and ease of routing, making it well-suited for street cars, track builds, and motorsport-inspired projects.

OEM-Style Connectors & Reliable Signal Routing

All wiring is constructed using OEM-style connectors and proper termination methods to ensure dependable electrical performance. Signal routing is designed to maintain clean communication between the engine harness, ECU, and chassis circuits while allowing flexibility for custom layouts.

Each subharness is built with serviceability and long-term reliability in mind.

Compatibility

Designed for K-Series engine swaps using either Hondata KPro ECUs or 2005–2006 K-Tuner compatible ECUs, depending on the selected option.

This universal subharness is intended for applications where chassis-specific subharnesses are not used or where custom chassis wiring is preferred.

Important Fitment & Support Notes

This subharness is designed to interface with VTEC Innovations K-Series engine wiring harnesses.

Because this is a universal solution, final chassis integration and termination are the responsibility of the installer.

Technical support is not provided for installations using third-party or generic engine harnesses, as compatibility issues introduced by non-VTEC Innovations harnesses are outside of our control.
