OBD2 1-to-4 Splitter Cable, 16-Pin Male to 4 Female

Comparison testing means one vehicle, four readers, and a lot of unplugging. The 1-to-4 splitter turns the single OBD2 port into four live sockets, wired full pass-through so every branch sees power, grounds and communication lines. It is the harness behind a working demo bench — and in fleet depots, the way to run a tracker, a speed limiter and a service tool without touching the port again.

The build carries RoHS-compliant connector and cable materials and a working range of -30 to +89 °C, matching the vehicle communication standards pin-for-pin. Branches leave at 90 degrees from the trunk, so four heads do not fight for the same inch of dash. For two- and three-device jobs, see our 1-to-2 and 1-to-3 splitters in the same family.

FAQ

Do four tools conflict on the bus?
The wiring is honest pass-through; conflicts come from the tools themselves. Power-only devices coexist freely, and bench setups usually assign one scanning tool per session.

Is this the same build as the smaller splitters?
Yes — same materials, temperature range and pass-through wiring, just more branches.
