1) the Earlier Bentley (8v up to 1984) shows no Blue/Lite Blue but does 
show Grey with Blue stripe. This is listed as dash illumination type 
wiring, supports the glow bulbs that come on when you turn on the 
headlights.

2) Don't use remote turn on to supply the 'bee stinger' Ant's amp until 
you get to specs: What is the amp looking for (volts and amps or likely 
milliamps) & What can the Radio's Remote Turn On supply? You might smoke 
something if these don't overlap.

3) You, sir, need a schematic but you also need a Volt/Ohm Meter. It'll 
tell you what has 12v with the Ign key ON as well as OFF.

My pref is to run a separate 12v hot straight from the battery through 
the  firewall w/ an inline fuse near the battery end. IN any case modern 
radios need uninterrupted 12v to keep station presets, shaft type radios 
don't care so do what you will. (Just how old is OLD in your case?)

Besides a good medium gauge hot* I also like a good radio case to 
chassis ground. It helps with power output as well as radio reception. 
This can be as short as say six inches or a foot (you need a _little_ 
space to get the radio out and back in place.)

*My additional wires are smaller around than battery cables but larger 
by far than any stock wire you will see in the car. Bigger, er Medium is 
better.
