Power drain from fuse 27 (or not)

[grounch]

Thanks for the links I'll have a look.
Did a first amp test, putting the meter between battery neg and the neg cable. Hacked the door and trunk by pushing the locks as it was closed, lights turned off but somehow the car didn't went to sleep this way (P light stayed on after 16min).
I got around 700ma after lock, then dropped to 400 300 after few minutes. However removing the 27 fuse doesn't seem to reduce it, but turned off P light.
Had no time today to go through all the glovebox fuses, will try later. Trunk fuses removal did not make amps drop.
