Question about Pre-FL R170 Radio connector

UPDATE: answered myself - these pins go to the CD player.

I'm replacing my Audio 30 head unit with a new Alpine unit -- keeping the factory amp and speakers. Looking at my 98 wiring diagram, I found two wires I don't understand - Connector C, pins 5 and 6. In the wiring diagram these only show reference to PE82.64-U-2000I.

I also am not quite clear on the antenna amps A2/18 vs A28/4.

Can anybody with STAR or the service manual 1) search for PE82.64-U-2000I and tell me what components these two wires attach to? and 2) tell me the locations for A2/18 and A28/4?

My radio is component "A2" in the wiring diagrams.
