I had a very similar situation with my Ford harness. I eventually tracked it down to a relay that was stuck in the open position. It was a real pain in the rear to find though.

Now think of it, I think the relay for the engine harness may be stuck also. Pulling the relay should not make any difference in the amp draw, correct?
How we find them is take the negative battery cable off, hook up a multimeter between the cable and the post with the multimeter on amperage setting, and then start pulling fuses until the draw drops. Have the door open but the door switch closed, that way you can access interior fuses but it won't be trying to turn on the dome light and similar accessories. You can also use a test light in place of the multimeter, just wait for the light to go out when you pull a fuse. However, with a tiny draw it's hard to see.

That's what I did. Pulled the main relay feeding the engine harness fuse panel, and the amp draw dropped from 0.5A to around 0.002A.
