1973 Fiat 124 CC Sports Coupe wiring diagrams

Post by uzz32soarer » Tue Sep 11, 2018 9:19 am

Hello guys from Melbourne, Australia. A new owner of a 1973 CC series 124 coupe to add to my stable of a 1963 500D, a 1965 2300S Ghia coupe, and a 1972 Dino 2400 coupe.

Yep, a Fiat fan!

My 1973 124 coupe has been fitted with fuel injection and turbo charged and this has meant that a lot of hands have been in and on her, under her skirts and in places I don't want to think about.

The wiring is a shambles, but except for the windscreen wipers, most things work!

I've been struggling with the wipers for three weeks pretty much solid and although I have workshop manuals for the car, I don't have a suitable wiring diagram for this year model. Colour coding on the 1970 model is different and tracing the wires through it appears to be a lot different from the 1976 Spider diagram that I've been using.

For the most part I've been able to trace the wires and amend the diagrams that I have, but there is so much damage, cut and shut mess, that I'm not even sure that the wiring to the actual fuse box is as it should be. ie: Brown power feed wire to the wipers should be on a switched supply from fuse 2 and it's on 12 and direct current!

Could anybody possibly help with accurate diagrams for the 1973 sport coupe?

Please send anything that you may have to rhayden@bluegumbs.com.au

Thanks in advance for any assistance.

Hey - I know the ‘72 Coupe was a five wire motor (having just sorted one). Is the CC coupe a 6 across all years?

Actually not really too helpful. That diagram doesnt show the fuse box nor have any wire colours. So it's quite difficult to know if the car is connected correctly. I'm currently working on a more suitable diagram, comprising details from a number of drawings that I'c\ve been able to locate which should be very helpful to 1972 - 75 1800 CC owners.

UZZ32soarer,

I can't offer any help in this topic, just wanted to say that your coupe is stunning! Might have to start looking to add one of those to my stable as well...

I will try to scan a wiring diagram I have - it is clearly a CC coupe, but the key i have for it is labelled 1973 124 Spider, so the key could have incorrect items (though at quick glance, the numbers all seem to be proper to their parts). The numbers for the taillights are definately wrong, as my key says 87 is the Rear stop lights, but 87 on the digram is the rear glass defogger. But the wiring diagram is definately CC coupe.


The wiper motor has six connectors, but 8 wires:

unnamed - grey/black
& grey

D - grey
C - blue black
F - blue white
INT - blue


37 - black
& black


I'll try to scan this later tonight, but I had it laminated so I'm not sure if the relfections from laminate will allow my scanner to work.

I don't really know what book it came from, or I would direct you there.

I scanned the wiring diagram in as a pdf. I didn't bother with the key, bc it is wrong (though close enough for Most things) and I didn't want it to get archived somewhere as the correct key.

The wiper motor is number 34

Try this one then ... sorry for the delay

If she’s got FI and a Turbo (is it a Legend one or an aftermarket?), then I’d be looking at the wiring diagram for a CS0 (available in the library - assuming it’s the Bosch LJet fitted).

1973 was a transition year for the coupes and the details varied from month to month and market to market. The attached 1972 and 1974 info may help but recognize that this is a US based forum so most of our info is for the U.S. market coupes. Try posting on this Australian-based forum for info the right hand drive models and turbo conversions: https://t124.com/forum/

Bradley has done a good job of loading whatever we could find on 1972 to 1975 coupe wiring diagrams in the library section of this forum.

If the turbo system is Legend-based, you'll also find some tech documents in the library section of this forum.
