bbfly B54 OBD2 Splitter 2-Way 1FT/30CM for Ford & GM — 16‑Pin OBDII Durable Extension

The bbfly B54 OBD2 Splitter is a compact 2-way 1FT/30CM OBDII extension that lets you connect two devices to a single 16-pin diagnostic port in Ford and GM vehicles without blocking the factory location.

If you need to run a GPS tracker, fleet device, or code reader alongside your factory diagnostic link, the bbfly B54 gives you a neat, robust solution designed to match Ford, Chevrolet and other GM 16-pin OBDII ports. This splitter is thicker than many on the market for improved durability, and its 30 cm length positions devices conveniently under the dash while keeping the original port accessible and unobstructed.

Will this splitter fit my vehicle’s OBDII port?

The B54 is specifically shaped for standard 16-pin OBDII diagnostic connectors used by Ford and most GM models. Before ordering, verify the port in your vehicle is a 16-pin OBDII—this is the only port type compatible with the cable.

• Designed for 16-pin OBDII diagnostic ports common in Ford, Chevrolet and GM cars and trucks.
• Fits the factory port location without forcing or altering trim pieces.
• Not compatible with non-OBDII or manufacturer-specific proprietary connectors.

How does the 2-way splitter help when installing tracking or diagnostic devices?

The two sockets allow simultaneous connection of two OBDII-compatible devices so you can run a GPS tracker or telematics unit alongside a scanner or dongle without unplugging one to use the other. The short, flexible 30 cm cable keeps devices tucked away under the dash for a clean installation.

• Two outputs let you power and read two devices at once—no constant swapping required.
• 30 cm length provides enough slack to hide devices while avoiding excess cable clutter.
• Thicker cable jacket offers improved wear resistance for long-term installs.

Will this splitter impact vehicle diagnostics or device function?

The B54 is an extension/splitter only; it passes OBDII signals to both connected devices. It is intended for standard monitoring and scanning tasks, but complex multi-device setups could create bus contention depending on how devices communicate—so keep installations simple and test devices together after installation.

• Pass-through wiring maintains standard OBDII signal lines to both devices.
• Ideal for trackers, basic code readers, and telematics hardware that share the bus.
• If two devices initiate conflicting commands, diagnostic behavior could be affected—verify with your device manuals.

Installation tips: confirm the port type first, route the splitter so it rests under the dash or behind the trim panel, and avoid pinching the cable when closing panels. For fleet or professional installations, ensure both connected devices are compatible with split-line operation.

Who is this for? The bbfly B54 OBDII 2-way splitter is ideal for vehicle owners, installers, and small fleet managers who want a tidy, durable way to power and connect two OBDII devices simultaneously in Ford and GM vehicles. It’s a practical choice for anyone adding a GPS tracker, telematics dongle, or keeping a dedicated code reader accessible while maintaining the factory port location.
