Quick update to help those in the future. I didn’t connect the blue wire from the metra harness as I didn’t know what to connect it to. The answer is the blue with white stripe wire from the head unit. Power antenna control is back. Also crutchfield rep told me that for illumination connection to utilize pin2 on the factory harness. On my 2000LC the wire was green. I made this connection but did not confirm the functionality yet. Hope this helps someone.
