Serial Cable Pin Out

[BAKERy]

Hi,
we are currently working on a 07 Mastiff here in the shop and need to connect to the VFI with Pro Tune. Nobody over here seems to have that 3-Pin Serial Cable. - Any chance someone of you guys has a pin out? Is there anything else special to that cable?

Thanks and regards from Germany,
Gerry

My VFI has a 9 pin serial connector, I use a USB to serial adapter with it.
If the db9 is the cable you mean I could always check it with the DVM (I got my cable from S&S way back)

Is this what you need?

Thank you guys! The diagram is what I was looking for. Can connect to the ECM now.
