Spotswood - Sucess !! - all systems are intact.
I found the errant white lead up under the glove box - then plugged it into the head unit - and, it's alive.
I took a detour on the wiring. I'm hooking it up to a previously installed micro-switch I put in the console 9 years ago. I don't like the idea of the antenna going up/down every time I turn off the radio, or the motor stalls during warm-up on cold days.
I ran a direct line to the fuse panel in the frunk for the power source.

FWIW I found the correct speaker plugs at Becker Auto Sound in Saddle River at $5 ea
They did not have the power plug for 12 V plus the antenna feed. (made my own, as you did)

Next couple of days will be the hard wiring, hiding wires and the FM signal enhancer, and splicing in some in-line fuses.
This year I will have tunes for the drive to Werks Reunion. YESSS.

Thanks for the tutorial in the auto antenna.

I had two of these radios, one with the 'record' function (original to the car), and one without.
Now that I have know-how, I'm going to attempt to install the spare into my 912E. That's a project for warmer weather.
