bbfly OBD2 Splitter B54 2-Way 30cm (1ft) — Low-profile Y-split with thicker insulation

The bbfly B54 OBD2 Splitter is a compact 2-way 30cm extension that lets you connect two devices to a single 16-pin OBDII port for Ford and GM vehicles.

Designed as a low-profile, durable Y-split harness, the bbfly B54 gives you simultaneous access to your vehicle diagnostic port without removing factory plugs. It’s built with thicker cable insulation than many generic splitters and made to fit neatly in the OEM diagnostic port area so GPS trackers, code readers or inspection tools stay connected and hidden.

How do I know this splitter fits my vehicle?

Confirming fit only takes a quick visual check: the port must be the standard 16-pin OBDII connector. The B54 is intended for Ford, Chevrolet and other GM models that use the typical OBDII layout; it preserves pin-to-pin connections so devices receive the correct signals.

• Works with standard 16-pin OBDII diagnostic ports.
• Specifically compatible with many Ford and GM models using OBDII.
• Maintains original pin mapping — no rewiring required.
• Short 30cm (1ft) cable reduces clutter around the dash area.

Can I use two devices at once without causing errors?

Yes — the B54 is a passive splitter that provides parallel access for two devices such as a code reader and a GPS tracker. It doesn’t alter signals; instead it duplicates the OBDII connection, allowing simultaneous communication for monitoring and diagnostics.

• Passive Y-split design duplicates OBDII connection.
• Compatible with scanners, telemetry boxes, and trackers that use OBD power and data pins.
• Short length and thicker cable reduce electrical noise and wear.
• Plug-and-play — no software or configuration needed.

How durable and discreet is the B54 splitter in everyday use?

The B54 uses heavier-gauge wiring and reinforced insulation compared with many lightweight alternatives, so it stands up to repeated plug cycles and in-cabin movement. Its compact Y-shape and moderate 30cm length let you tuck devices out of sight while keeping access simple for service or scanning.

• Thicker cable jacket for improved abrasion resistance.
• Compact form fits factory diagnostic port locations cleanly.
• Short cable avoids messy loops under the dash.
• Designed to protect connected devices from accidental unplugging.

Will the splitter affect vehicle diagnostics or warranty?

The B54 is a passive connector and does not modify vehicle systems; it only duplicates the existing OBDII signals. As with any aftermarket accessory, use according to manufacturer guidelines and remove the splitter if a dealer requests a direct single-device connection for warranty diagnostics.

• Does not change ECU programming or OBDII signal content.
• Meant for accessory use — remove if instructed by service personnel.
• Non-powered, no electronic modules included.
• Preserves OEM connector layout for easy reinstallation.

Who is this for: The bbfly B54 OBD2 Splitter is ideal for vehicle owners or fleet managers who want to run a GPS tracker, telematics box or OBD scanner at the same time without unplugging equipment. It suits DIY mechanics, installers, and anyone who needs a tidy, reliable way to share the OBDII port on Ford and GM vehicles while keeping devices hidden and accessible.

Note: Always verify the diagnostic connector on your vehicle is a 16-pin OBDII port before purchasing.
