The fact that moving the ETA wiring harness around causes the ETA motor to activate leads me to believe it could be a bad ETA wiring harness or a bad connection where the ETA harness connects to the ETA circuit board inside the unit. This is exactly what happened on my old 400E. Like you, I discovered it by accident when I was trying to figure out why my CC didn't work and I leaned on the air cleaner and heard the ETA motor activate. I never did replace it because once I positioned the ETA harness to where the ETA motor was working, I never had any more problems with it.
As for the missing fuse, I have a 95 E420 without ASR. Let me go out and check it for you to see how many fuses there are.
UPDATE: Here's a picture of the module box for my 1995 E420 non-ASR. It has four fuses. I don't know how different your 92 Japanese model would be from this, but I would think that if it was running fine before on three fuses then a missing fuse is not your problem. Can you get the car to start by moving the ETA cable until you hear the ETA motor running?
