Canbus sniffer V2

Hi all , currently playing with the V2 canbus shield and I am using a DB9 to OBD cable.

I am wanting to get more data than just basic OBD such as engine speed and wheel speed and looking at connecting to other protocols over the networks.

I understand that only 6 and 14 is used for OBD Lead so can I use the push fit connections and create my own OBD lead for connection to other pins within the OBD? I’d like to be able to see messages such as button press of steering wheel, radio turn on signal etc.

Thank you
