The Link G4X CivicLink HC96X (206-4000) is the Honda 1996–1998 OBD2A ECU platform this loom is built around. The harness brings Link-specific engine-management connections, additional sensor provisions, and selectable trigger configurations into one engine-side assembly.

A purpose-built Link ECU PNP engine loom designed for OBD2A Honda H/B-series applications, with direct C101 chassis integration and integrated sensor wiring and engine-management connections.

Developed around the Honed Development dual K-series crank/cam trigger system, this loom provides a clean path to modern sequential ignition and engine management while retaining straightforward Honda chassis integration.

Built as a complete engine-side loom — not a universal standalone harness or adapter.

Sensors are not included. The sensor connections below are pre-wired provisions for separately purchased sensors.

Integrated From the Start

The additional standalone circuits are built directly into the loom, including:

• Bosch combination-sensor wiring with a 5-pin connector
• Two AEM pressure-sensor wiring provisions with Aptiv/Delphi-style 3-pin connectors
• One additional AEM temperature-sensor wiring provision with an Aptiv/Delphi-style 3-pin connector
• Wideband DTM connection
• Spare ECU input
• Spare ECU output
• Direct coil-fire wiring
• Direct injector wiring
• OBD2A C101 chassis integration

Everything is integrated into one clean engine loom instead of relying on a collection of external add-on harnesses.

Configurable Trigger System

The loom architecture supports multiple ignition and trigger configurations:

Stock Distributor · Honed Development · Snake · T1

The pictured/development configuration utilizes the Honed Development dual K-series crank/cam trigger kit.

Select the appropriate termination when ordering.

Injector Options

Injector connector configuration is selectable to match your injector setup.

Built for H & B Series

Designed around common OBD2A Honda applications including:

H22 · H23 · B16 · B18 · B20

The same VTI production architecture carries across the platform while allowing the engine, trigger, injector, and ECU configuration to be specified at order.

VTI Motorsports Construction

Built to the VTI Motorsports standard with controlled routing, Motorsport-grade connectorization, integrated branch construction, wire identification, and full electrical testing before leaving VTI.

The result is a clean, serviceable engine loom that gives a modern Link ECU installation the fit and integration of a purpose-built Honda harness.
