live from the fuse box under the bonnet, looks like oem, ignition for the amp from cig lighter or headunit, depends what have you got inside, audio cables using high low adapter from the rear speakers or from the unit. Good high low adapters has amp ignition option too. If you have rcd510 or rns headunit, it can be coded for the active system, which would convert the signal, but you would need to modify the harness to add plugs for audio signal. For ignition aswell, I think pin 6 is correct one.
