K-Series Universal Chassis Subharness – KPro / K-Tuner Compatible | VTI

For Custom Builds, Race Cars & Non-Standard K-Swap Chassis.

When a chassis-specific subharness doesn't exist for your build — or your factory under-dash wiring has been modified or removed — this is the solution. The VTI Universal K-Swap Chassis Subharness interfaces K-Series engine wiring with custom or simplified chassis wiring, giving you clean signal routing and flexible termination without being locked to a specific OEM chassis connector layout.

Ideal for custom builds, race cars, and projects that need adaptable routing rather than fixed OEM chassis integration.

ECU Compatibility Options

• Hondata KPro — supports common K-Series swap configurations using KPro engine management
• K-Tuner 05–06 ECU — 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.

Important Notes

Designed to interface with VTI 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.
