OBD2 3 Pin To 16 Pin Diagnostic Adapter Cable

A diagnostic adapter cable converting the 3 pin service connector used on Fiat, Lancia and Alfa Romeo C and A5 models to the standard 16 pin OBD2 socket. Without it, a modern scan tool cannot reach those vehicles at all.

  • Connects modern 16 pin scan tools to the 3 pin Fiat family service port
  • 40cm length keeps the tool clear of the pedal area during a drive test
  • Moulded connector bodies handle daily workshop use
  • 250g assembly stays put on the dash rather than hanging on the socket

Quality Control And Certification

  • Continuity And Circuit Verification. Verifies the physical arrangement sequence of the harness terminals and the circuit topology between them
  • Circuit Configuration Verification. Confirms that a complete, uninterrupted current flow path exists within each circuit
  • Terminal Retention Strength Test. Measures the mechanical reliability of the connection between the terminal and the wire
  • Ingress Protection Rating Test. Evaluates the dust and water resistance sealing performance of harness connectors

The company is certified to IATF 16949 and UL standards. Samples are confirmed prior to trial or mass production, and the approved sample is the reference for every repeat order.

Customization Options

  • Connector family and terminal type to your part numbers
  • Conductor gauge selected from the current per circuit
  • Finished length and breakout positions to your drawing
  • Jacket colour, marking and labelling to your scheme
  • Packing to your instruction, PE bag and carton as standard

Compared With The Alternatives

Universal OBD adapter kits

A dedicated 3 pin lead is wired for this vehicle family rather than pin-jumpered

Improvised jumper leads

Moulded bodies and fixed wiring remove the risk of a shorted service port

Use Guide

  • Switch the ignition off before connecting or disconnecting the adapter
  • Support the adapter on the dash rather than letting it hang on the socket
  • Keep the cable clear of the pedal box during any drive test
