Key Features

• Universal OBD2 Compatibility: Standard 16-pin male connector plugs directly into any OBD II port; open-end pigtail wires are perfect for DIY wiring harness builds and custom installations.
• Oxygen-Free Copper Conductors: High-purity, oxygen-free copper ensures excellent signal transmission with minimal resistance — keeping data communication fast and reliable.
• Tinned Connector Pins: Tinned pin contacts resist oxidation and make soldering or terminal crimping far easier for DIY builds.
• Flame-Retardant PVC Jacket: 7 mm thick PVC sheathing made from flame-retardant, environmentally friendly material — durable, flexible, and resistant to everyday wear and abrasion.
• Color-Coded Pin Map: All 16 pins are individually color-coded for easy identification and correct wiring every time:
  1-Black | 2-Brown | 3-Red | 4-Orange | 5-Yellow | 6-Green | 7-Blue | 8-Purple | 9-Gray | 10-White | 11-Pink | 12-Light Green | 13-Black & White | 14-Brown & White | 15-Red & White | 16-Green & White
• Multiple Length Options: Choose 0.3 m, 1.5 m, 2 m, or 3 m to match your installation needs — from tight under-dash installs to longer routing runs.

Frequently Asked Questions

Q: Is this OBD2 extension cable compatible with my vehicle?

A: Yes — this cable is compatible with all vehicles that use a standard OBD2 / OBDII 16-pin diagnostic port, which includes the vast majority of cars and light trucks sold worldwide from 1996 onwards. It also works with popular scan tools and interfaces that use the ELM327 protocol.

Q: Can I use the open pigtail end for custom wiring projects?

A: Absolutely. The open-end pigtail design is ideal for DIY automotive wiring projects. The 16 conductors are individually color-coded by pin number, so you can easily identify, crimp, solder, or terminate each wire to suit your specific installation needs.

Q: What length should I choose?

A: Choose 0.3 m for a compact under-dash install where you just need a short extension to reposition a dongle. The 1.5 m option suits most standard routing runs inside the cabin. The 2 m and 3 m cables are ideal when the OBD port needs to be relocated further away or when routing behind trim panels adds significant length to the cable run.

Q: Is the cable safe to use in a vehicle environment?

A: Yes. The cable jacket is made from flame-retardant, environmentally friendly PVC with a 7 mm thickness for robust protection. The oxygen-free copper conductors with tinned connectors ensure a reliable, corrosion-resistant connection in automotive environments.
