What it Brings to Your Build

Durability meets practical design. The housing uses robust ABS plastic for a solid feel, while the internal copper conductors are PVC insulated to resist wear and corrosion. This combination helps maintain stable electrical performance across a range of temperatures and drive conditions.

• ABS housing offers a sturdy, long-lasting shell
• PVC insulated copper wires encourage reliable conductivity
• Corrosion resistance supports sustained performance

Easy, No-Modification Installation

Install in minutes with a true plug-and-play design. The red plug connects to the car’s OBD2B port, and the gray plug links to the OBD1 device. No wire cutting or splicing is required, helping preserve factory wiring and simplify setup.

• Plug-and-play; no wire cutting
• Red to OBD2B port, gray to the OBD1 device
• Clear color coding reduces the chance of misconnections

Real-World Scenarios

Whether you are updating ECU software, testing configurations, or maintaining a familiar ride, this harness offers a tidy, dependable interface. Expect a compact, uncluttered setup that tolerates engine bay vibration and fits within typical layouts.

Note: Compatibility depends on the exact computer and harness specs, not the engine alone. Always confirm the model year and configuration to ensure a proper match.
