Good info for everyone thank you!

1994 FSM pics, hopefully similar to a 90.

There is actually a Blue wire in the Metra wiring harness that is for the Amps that is listed as Power/Antenna. Hooked that up and have surprisingly decent sound out of the Bose System without a problem. The wire I am referring to that I couldn't ind was the actual Antenna for reception which *I think* is a thicker 14 gauge wire. I remember it being more obvious in my 1992, but that was years ago and I've slept since then.

Same here. The blue (with white stripe?) amp wire on my metra harness wire is going to the dark green wire.

Oh, sorry! Yes, that is a big chonky black shielded coax type wire. The car side of that should as far as I know be under the tray of the rear passenger storage compartment. That's where mine is, then the metra harness plugs into that end and has its own antenna wire that goes up to the radio unit.

Unfortunately on the 90-92 the CDM is behind/under the glovebox instead of behind the seat. (Which would have only been 11,000x easier). Also the reason the CDM is still in place instead of removed, because getting it out of there is a royal PITA. lol
