Do you have the owner's manual in the glove box? You'll find this info in there.

I have a '73. This is what's in my manual. Might be different for a '74.

here you go

Thanks guys!

Hmm, I have a '74, but it's not a US model. I was looking at the fuses today, because I am adding in a subwoofer and I am going to put that on a separate circuit with an auxiliary fuse, either 10 or 16A.

I am hooking the auxiliary fuse input side to the hot side of terminal S12 - that looks to be 12V, direct to battery - the incoming wire is also pretty heavy gauge. There is actually even a free spade lug there on mine. The other side of the auxiliary fuse will go to the radio and subwoofer.

According to this:
https://bowlsby.net/914/Classic/zTN_Elect_FuseIndex.jpg

Fuses S8, S10 and S12 should be 16A, all the others 8. On mine, both 8 and 12 are 16A, but 10 is only 8A.

S10 is supposed to be for the fog lamps and the horns. My car has the aux lights in the bumper, but they are not fog lights, they are driving (distance) lights - clear lenses, no ribbing. And, there is no separate switch on the dash for these lights. They go on with the high beams, and if the headlights are retracted, flicking the brights lever switches them on as well. I like this arrangement, you can "flash" an oncoming driver without raising the headlights. I'm not sure if all the "Euro" cars work this way, or maybe just those delivered in France...

I am thinking I should replace fuse S10 with a 16 amp guy. If I have the headlights on with the high beams (i.e. aux lights on too) and I hit the horn... I don't know what wattage the aux lights are - haven't taken them out yet to look. If they are 55W, that would already be 9A alone... So possibly they are 35W, which would draw only 6A. No idea how much the horns draw.

Does anyone have an actual wiring diagram for a '74 non-USA? I can't make heads or tails of the '74 "Current flow" diagrams in the manual.

I have a beautiful 14" x34" hand-drafted wiring diagram for my '57 T-Bird, it's a work of art...

@chmillman

i don't have wiring diagrams for euro models.

but i did have this on file from some L jet research i was doing.
owners manual out of 74 french market 914.
the fuse rating layout does seem different to the USA models.
don't know if this helps.

Nice to know that they speak French near the antarctic.

multilingual international research base down here.
we all drive red vintage VW beetles around on the ice.

this was yesterday. its supposed to be spring time.
the roaring forties normally blow well south of north antarctica.
(the old clipper ship trade winds).
well, whether its global warming, or whatever it was, the winds came way north.
its been like this for a week but yesterday was the peak of the frenzy of weather.
freezing cold gale force winds. i swear i thought the roof was going to get sucked of my place at least a dozen times yesterday.
and this hit. (i took photo half an hour after the event when 50% of it had melted).
a solid 3-4 inch carpet of hail on the ground.
i've been through some hail storms in my times but this was the maddest.
not big hail. but like a tropical downpour of hail. just immense volume of it suddenly.
but worse the gutters in my research facility completely overfilled with ice.
and as it slowly melted the whole building leaked everywhere along the gutter lines for about 5-6 hours afterwards.
frantically throwing tarps around everywhere and went to the supermarket to buy all the buckets left on the shelves.

still mopping up this morning.
had the 914 parked under one of the gutters. with the roof off.
i was quick to get a tarp over that situation.

@worn , @wonkipop

Thanks for the manual photos! 8 amp fuse already replaced with a 16-er.

I do have a Haynes manual (reprint) but the '74 "Current flow diagram" that replaced the '73 and earlier "Wiring diagram" is just painful to try and read. Maybe someday I will redraw it and put actual labels on the page instead of numbers/letters in circles and squares that you need to look on another page to try to figure out what they are.

yes - you have my sympathy - its a black and white diagram in haynes.
i do have colored ones but its from the USA workshop manuals and only covers USA market cars.

There is very little difference between the Euro and North American harnesses. Mostly due to the lack of side markers on the Euro cars, and the brake warning light.
