Yep, looks like pin 6 would go straight to the subamp line in. But you need a ground line from the head unit to the amp, which probably just means a shared earth, which is probably the AF earth on pin 3.
I'm would expect the sub's amp to have a line in pin and an AF earth pin to which those would be wired, respectively.
