Available Wiring Diagrams

[pstiff]

Moderator feel free to delete this post if the information already exists somewhere.

I did not see 115.38 The Euro Spider of 1984 on the list of available wiring diagrams. I scanned mine, so here it is.

I just added the key to the diagram - easier to use

[papajam]

Thank you for sharing this diagram, pstiff. I've printed it and it's on the list to colorize.

Could you pls supply me with the wiring diagram for my alfa 33 1500cc. I've finished restoring, just do wiring.

thanks

[papajam]

I'm sorry logan. I do not have the diagram that your looking for.

Hi,

We are in need of the wiring diagram for a 1965-66 Giulia Sprint Veloce.
The wiring for the instruments is what we are really in need of, can you help ?

Thanks,

Mario or Paul Colasacco

Hi papajam,
was wondering if you would have the wiring diagram for a Alfa Romeo 164, 3 litre v6, 12v, 1991 model. What I am trying to find is a complete wiring diagram of the vehicle and where everything connects up to. Have already gone through the shoreys car disc that I got offline but it dosen't actually give you a full wiring diagram of the car. Hopefully you can help us or point us in the right direction

Cheers

The 72/73 Spider & GTV as well as the 76/77 Spider diagrams have been split into separate diagrams because of slight wiring differences. The 10536 listing on the 10502/10536 diagram has been removed as there are numerous color code differences particularly in the headlight wiring.

There are many black and white wiring diagrams available as well. 10102 Giulietta Sprint 10103 Giulietta Spider 10104 Giulietta Spider 10105 Giulietta Sprint 10106 Giulietta Sprint Veloce 10107 Giulietta Spider Veloce 10118 Giulia Spider Veloce 10123 Giulia Spider 10125 Giulietta Spider Veloce 10502 Giulia Sprint GT 10503 Spider 1600 (Duetto) 10521 2000 GT Veloce 10524 2000 Spider Veloce 10526 Giulia Super thru 1967 10526 Giulia Super from 1968 (with generator) 10530 Giulia GT 1300 Junior Series 1 10530 Giulia GT 1300 Junior Series 2 10530 Giulia GT Junior 1.3 Series 3 10530S Giulia GT Junior 1.3 Series 4 10544 1750 GT Veloce Series 1 10544 1750 GT Veloce Series 2 10551 1750 GT Veloce 1969 10551 1750 GT Veloce 1971 10562 1750 Spider 1969 10562 1750 Spider 1971 10591 Spider 1300 Junior 10602 2600 Sprint Series 1 10602 2600 Sprint Series 2 11500 2000 Berlina 1972 11500 2000 Berlina 1973 11501 2000 GTV 1972 11501 2000 GTV 1973 11501 2000 GTV 1974 11502 2000 Spider 1972 11502 2000 Spider 1973 11502 2000 Spider 1974 11502 2000 Spider 1975 49 State 11502 2000 Spider 1976 49 State 11502 2000 Spider 1977 49 State 11503 Giulia GT Junior 1.6 Series 3 11534 Giulia GT Junior 1.6 Series 4 11535 Spider 1.6 11538 Spider 2.0 11541 2000 Spider 1977 California 11541 2000 Spider 1978 11541 2000 Spider 1979 11541 2000 Spider 1980 11541 2000 Spider 1981 11541 2000 Spider 1982 11541 2000 Spider 1983 11541 2000 Spider 1984 11615 Sprint Veloce 1977 with Air Conditioning 11615 Sprint Veloce 1977 without Air Conditioning 11615 Sprint Veloce 1979 with Air Conditioning 11615 Sprint Veloce 1979 without Air Conditioning 11629 Alfetta GT 2000 1975 without Air Conditioning 11629 Alfetta GT 2000 1976 with Air Conditioning 11629 Alfetta GT 2000 1976 without Air Conditioning I've spent many, many hours drawing each of these diagrams wire by wire and while I ponder quitting my day job and retiring on the proceeds of the sale of these things, they are still, for now, free. However, if you ask for and receive any of these diagrams, all I ask in return is that you consider making a donation to the AlfaBB. Please mention in your donation that it is, perhaps only in part, for a wiring diagram. If you need any of the above mentioned diagrams, please send me a private message with your email address and I'll get it to you. Let me issue this public THANK YOU to those who were kind enough to supply me with copies of original Alfa diagrams and pictures of various devices so that they could be drawn as accurately as possible. Without your help, some of these diagrams could not have been drawn. This list will be updated as new color diagrams become available.

Papajam, I'm stuck on a client's car wiring. Do you by any chance have this one in color and has been corrected?

It is totally screwed up in the area of the turn/headlamp switch and what color of wires attach to what colors on both sides of the six-way connectors.

Hopefully you'll know what I'm talking about but I'll try to explain better by using an example using the yellow wire. The wiring diagram I have shows the yellow wire coming from the headlamp switch, then attaching to a yellow wire on the female side of the six-way connector and going to the IN side of the #5 fuse.

In reality the yellow wire comes from the turn signal and attaches to dual blue wires on the female connector.

It is identical on both '69 Spiders I have in the shop.

There had been numerous shorts along with numerous lights not functioning on the client's '69 which I'm working on and they'd been patched. I, perhaps naively, believed the color of the wires going into and out of the fuse box on the wiring diagram I have. So now I have to trace each wire as to where it is coming from and where it attaches on the fusebox or(?), no matter what color it might be.

I've restored a number of '69 Spiders but never had to do such an extensive rewiring, and merely plugged in the two halves of the six way connector and everything worked (generally or eventually).

I am lucky to have a spare car to double check, but if you have a corrected wiring diagram, it sure would be helpful.

Also, the wiring for the emergency flasher is totally screwed up on the wiring diagram.

I received this diagram from a client who I believe printed it out from a CarDisc.

The good news is that I have a color diagram for the 10562. The bad news (perhaps) is that it was drawn using the original Alfa diagram as a guide. If there are any color code discrepancies on the original, they were drawn into the color version.

Memory tells me that Alfa used the same color wires for certain things for many years. An example of this is the headlight/turn signal switch. The headlight switch uses yellow for the parking lights, and green and gray for the low/highbeams (I think). Later switches added a gray/black stripe wire for a separate highbeam circuit (I'll assume to reduce the load of two high beams thru one contact). The turnsignal switch uses black as the power in. Blue is the output to the right signals and blue/black for the left signals.

Having said that, the difference in the switch color codes could be with the Jaeger supplied switches. Perhaps Jaeger switched the colors? Since the switch wires go into a mutipin connector that can be plugged in only one way, a specific color at a specific pin number might be considered irrelevant (except of course when one needs to diagnose the thing). OTOH, there may be an Alfa published document that describes this change (I've not seen one though if there is).

Then of course Jaeger could have employed the Alfa practice of using what was on the shelf for the task at hand without documenting it. If so, then it may not be that the diagram does not match the car but rather the car does not match the diagram.

I'll email you the color version this evening.

Jim, much appreciated. Are you at all interested in corrections for this wiring diagram or is it too tedius to change? I'm not going wire by wire, but I am making corrections on my b/w schematic (though have used Prismacolor pencils to designate some colors). In my case I'm only making corrections if both 69's are the same.

[papajam]

Sure, I'd be happy to modify a diagram for you. Just let me know what color wires go where.

[Zunige]

Jim,
Have you done a wiring diagram for the series 4 Spiders ('91-'94)?

Best regards,

[papajam]

No, I haven't.

As a result of reading thousands of automotive and industrial wiring diagrams over the years, certain attributes, to me, made for a much easier read. Things like color, writing the name of each color on each wire, identifying each wire (and its size) in numerous locations from point to point, having each device in it's approximate location in the system and naming each device. Having large enough type for aging eyes doesn't hurt either. These are some of the reasons for drawing the color diagrams.

Having said that, I think that the S4 diagrams in the service manual are much improved simply by doing away with the coded device format. Now although the break out of each sub system (separate drawings) makes for an easier understanding of each system, sometimes one needs to know how each sub system fits into the grand scheme of things. So it's a toss up as to how many sub systems put together will over complicate and clutter a diagram verses showing how the sub systems fit into the overall electrical system. The 1986-1988 Spider diagrams were condensed from 20+ pages to four pages for this reason.

Long story short, should add the S4 diagrams to the to do list?
