1975 Porsche 911S Fuse Diagram

[wrxnofx]

Can anyone give me a layout of the fuses/relays in a '75 911S fuse box?

I can't find one anywhere. The Technical Specifications booklet for sure has this but I don't have a copy of that document, unfortunately.

The fuses/relays should be printed inside of the frunk fuse box cover.

Though I would like a paper color copy of the fuses as well. Easier to see.

I can post a photo of the inside of my fuse box cover if you want.

A pic of the inside of the cover would be great! The cover in this car is not original and has nothing in it. Knowing which fuse is for what would make it WAY easier to diagnose some of the lighting problems this car has. Same for the relays - I don’t know if they’re for the horn and fuel pump or something else. I had read the ‘75 didn’t have a relay for the fuel pump.

I wasn't able to find an actual diagram, but from searching one post did pop up with some information that might help you. Scroll down a bit and you will find someone who typed out info from a 74.

Cross reference the list above with the photos of the fuse box cover that came with my 1975S

EDIT: I ran the part number through the PP web site and got this for the fuse box cover.

This is what I have in my 'tech' folder. Do not know what year it is for though. I think it is meant to be printed out.
