OBD2 1-to-3 Splitter, 16-Pin Male to 3 Female

This 1-to-3 adapter turns a single OBD2 socket into three, so a diagnostic tool, a GPS tracker and a second scanner can stay connected at the same time without being unplugged every time. It is the usual fix in workshops, inspection lanes and fleets where the port is in constant use.

All sixteen pins pass straight through, so every protocol the vehicle supports reaches each connected device. The moulded sockets are built to resist the sideways load of a dangling plug and to hold a scanner firmly without wobble.

FAQ

Will all three sockets work at once?
Yes. All 16 pins are wired through, so several devices can stay connected. Some scan tools cannot share a vehicle bus, so test with your own equipment.

Does it work with 24 V trucks?
It passes the vehicle’s own voltage through, so check your tool’s input rating before using it on a 24 V system.
