Yanhua ACDP 2 OBD Extension Cable

What it does

It is basically a male-to-female OBD2 extension lead that lets you:

• Connect the ACDP2 device to a car’s OBD2 port more easily
• Extend the cable when the port is hard to reach or recessed
• Avoid hanging the ACDP unit directly on the OBD socket (better stability during programming)
  

  Simple summary

  It’s not a diagnostic tool by itself — just an extension cable that helps the ACDP2 system connect to the car’s OBD port more conveniently and safely.

  If you want, I can tell you whether you actually need it for your specific ACDP modules or if your setup already includes one.
