Blue (I think) wire at the CDM box. Pass side of dash.. Or back behind the package cover on the driver side

And when you play CD and if you are running navigation head unit which stays on all the time.
I installed a switch and keeps my antenna down. Around town, even with the antenna retracted, have no issue receiving FM and HD FM signal.

Marc installed one for me under the carpet behind the driver seat. Saves the up and down big time.

You have an aftermarket Pioneer nav unit? If so, look at installation electrical schematic.

on a 1990-1 passenger side there is a CDM. The main radio module, that is where. I don't have pictures though
