I could be wrong about the head unit. I was thinking of high power units
that can draw a lot of power. If this is is a lower power unit, it might
not have the high current lead. It would probably have a "pink" wire for
the low current memory lead, and the current required might be tiny, and
not mentioned in the consumer level manuals. I see a rating of 5mA for
some head units.
What about the light bulb in series with just the power for the Pioneer?
You could connect it across the fuse holder with the fuse out.
(The draw of the Pioneer is interesting to me. I don't know what the draw
for the rest of the car ought to be.)

Re: Parasitic Drain - Bulb Trick
Just re-measured the standby drain today... Now it's at around 60 mA.
I haven't really changed anything, so I'm really baffled now.
Maybe it was a "ground" of some kind caused by water from the engine
wash (alternator got wet)?
The water could have dried out by now, resulting in the more normal
reading.

BTW,if you want to extend the DC amps range of your inexpensive DMM,use a 1
ohm resistor in series with what you want to measure(use short heavy leads
soldered to the 1 OhmR),and the DMM measures across the 1 ohm R.
Since I=E/R,1 volt across 1 ohm= 1 amp.
If your DMM has a 2V range,that's 2 amps full scale.
I'd use a 10W 1 ohm WW resistor.

I forgot to add "volts" so it would read "and the DMM measures VOLTS across
the 1 ohm resistor."
