Finding parasitic draw - 80s 4Runner

[RatLabGuy]

Chasing down a parasitic draw that slowly kills my battery.
Sitting w/ everything off, no radio installed and the center bezel removed, I measure 41.5mA between the negative battery terminal and lead.
Its not a huge amount but I'm like to find out where this juice is going.
On the fuse block under hood by the p-side fender if I remove the "AM1" 40A fuse it drops by about 12mA. I have no idea what this fuse is but I can probably hunt it down.
I then pulled each remaining fuse, both in the udner hood block and the block under the drive side kick panel - no change in draw. Suggests there's another circuit somewhere...
But... where? Is there a 3rd panel somewhere I don't know about? Any other suggestions where to look?

pull the relays and check

Do you still have the rear power window relay installed?

Disconnected ECU, no change in draw.

Start by getting a good /reliable diagram before you do anything.

If you measure current with a multimeter on the fuses you can pinpoint the circuit no need to pull fuses

alternator?
