Brown/ black is the ground.

Not a radio wire.

Not a radio wire

This is your ignition power, although it should be Violet/Gray.

>White: Continuity with ground.

There are two white wires, one is your antenna trigger, the other is
dash lights.  The full time power wire is yellow and shares a two pin
connector with the dash light white wire.

>Grey (thick steel tipped):  Is this the antenna trigger?

This is the antenna lead.

Does the car have an in dash fader wheel ? If so, and you are not
installing a factory radio, do yourself a favour and run new speaker
wires throughout the car.  The in dash fader uses common grounds and
hooking an aftermarket radio to this wiring can cause it's output
channels to take a dive.
