Hi all, I'm having trouble connecting to the Body computer using an ELM327 and a yellow adapter. Can anybody send me the wiring diagram of the adapter, or give any assistance?
I'm trying to perform the proxy alignment on a 2013 Fiat 500.

I can connect to the Engine, ABS, and other modules that don't require a yellow adapter, but I am unable to connect to any other.

I reckon that all the adapter wiring diagrams are viewed from the soldering side of the connector?

Any info and help would be much appreciated.

Thanks

Wiring diagrams are on the right.
