OBD II 16 Pin Splitter Extension Cable - 1ft 5 Pack

In this review the reviewer looks at the bbfly OBD II 16 pin splitter extension cable pack to decide if it belongs in a technician's toolbox. The bottom line: this 1 ft, 5-pack extension is for anyone who wants to protect a scan tool's OBD connector and add simple OBD-2 accessories without risking wear on the primary plug. Its single biggest benefit is passing all 16 pins straight through with no shared ground wires, which maintains a direct, reliable connection for diagnostics and add-on modules.

Key Features

• Full 16-pin passthrough: Ensures every diagnostic pin is carried straight through so tools and accessories receive proper signals.
• No shared ground wires: Prevents ground routing issues and preserves signal integrity for sensitive readers and modules.
• Ultra flat low profile: The slim, low-profile connector sits neatly under dash panels and reduces strain on the vehicle port.
• Durable, flexible cable: High-quality materials give the cable enough flexibility to route in tight spaces while resisting repeated bending.
• Saves wear on tools: Acts as a sacrificial extension so a scan tool's original OBD connector sees less wear from frequent plug cycles.
• Pack of five: Provides spare extensions for multiple vehicles, technicians, or projects without separate purchases.

Who It's For

This extension pack is ideal for professional mechanics, diagnostic technicians, and car enthusiasts who regularly connect scan tools or add OBD-2 accessories and want to reduce wear on their primary connectors. The short 1 ft length suits tight engine bays, under-dash work, or situations where a compact extension is preferable to a long cable.

It is less suitable for users who need long reach or integrated indicator features; this is a basic, no-frills extension intended to maintain connection quality rather than add functionality. Buyers who require manufacturer-branded packaged cables or specific proprietary wiring changes should look elsewhere.
