I have a 72 911T. The sticker on the cover of the engine fuse cover is missing. from top to bottom, what is the fuse amperage and what does each fuse control. FWIW, I have the single stage rear defogger if that makes a difference

I don't believe there was a sticker, the fuse info is embedded on the inside of the cover if memory serves me right.

If mounted correctly, the engine fusebox should be in the order of position 3,2,1 from top to bottom.
Position 3 should have a black/red wire and a red wire on either side. It is an 25 Amp fuse. The red (a thicker red wire than the same side one that goes to fuse position 1) comes from the starter motor and is always live. The red/black goes to rear window defogger relay.
Position 2 should have a red/white on one side. The other side is bridged to position 1. It is an 8 amp fuse. The red/white goes to the cold start valve relay (for MFI) and the speed relay for the anti-backfire function for MFI.
Position 1 should have a red wire coming to it and nothing leaving. This is a 5 amp fuse (if anything is actually installed) and is supplied by switched power from the ignition switch via the 10 fuse panel in the frunk. Not sure what accessory it is used for. I've usually seen no fuse in this position.

Position 1 is for the Sportomatic switch, terminated with a blue/yellow wire on 70/71’s.
Actually, I don't believe there was a cover for the engine fuses in 72/73. The big plastic cover with the two knurled knobs over the whole rear console was all that was provided. I think I asked about this once in my build thread.

Yes and that was stuck on the inside of the plastic cover but suspect it didn't stay there for long as only ever seen one original which is what my copy was made from
