F22 HK Amplifier Connector Pinouts

Im adding an aftermarket amp for a subwoofer and i need remote amp turn on lead, and speaker wires for a line-output-converter to RCA. I'd like to pull these wires straight from the factory harness.

Does anyone have the wiring diagram of the Harmon Kardon amp connectors ?

Are the factory battery terminals good for ring terminals, or does it need to be extended with studs?
