As many of you may know by now, and as new members are finding out, a few of the color wiring diagrams that I've drawn have been (and will continue to be) available here on the BB.

The 'R' following each model listing indicates that diagram's Revision number. Please check back from time to time to see if your diagram has been revised so that you can get the latest version. The revision number on your diagram is in the lower right hand corner next to the copyright. No revision number means that the diagram is a first edition. Most revisions are the result of additional information being added, usually obtained from actual vehicles, and graphics changes to improve the readability by more accurately depicting a device's actual location in the vehicle.

If you do not see what you're looking for, please PM me with your needs. There are many factory black and white wiring diagrams available for many models from the 1950s through the Series 4 115 Spider.

For 750 Series cars with 6-fuse fuseboxes, please click here. Fellow BB'er dabraham has done a marvelous job at creating these.

PLEASE NOTE: The color wiring diagrams listed below are copyrighted. While they are available free for the asking, they are not to be made publicly available without permission.

PLEASE NOTE #2: When requesting a diagram, please include your email address. I can not email a diagram without an address.

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 becoming a paid subscriber to AlfaBB.

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, descriptions and pictures of various devices with their physical locations in the car and countless other details from actual vehicles so that these diagrams could be drawn and revised as accurately as possible. Without your help, some of these diagrams could not have been possible.

Hi Andy,
I haven't drawn a color version for the 88 Spider (yet?) but I do have an original (about 20 pages). I could email it to you if you'd like.

Hi Andy,
Unfortunately, no, I don't have an 01 Spider diagram. Nor do I know where to find one. Schiff European ( ) currently does not have one listed but perhaps sending a quiry will prove positive. Good luck!

Thanks, alfaman! Every bit helps.

Spider 1991

I am looking for a wiring diagram for my 1991 Spider.......

It's been converted to RHD by Seaking (don't know if this makes any difference:confused: )

Any help would be most welcome :)

Hey Papajam. You seem to be the Guru on Alfa wiring. I have a 59 Milano with the generator and regulator taken out. The old regulator has 6 wires going into it, the new one only has 5 post on it for the wiring. My Client has no clue because he didnt pay any attention to the wiring when he took it apart. Can you give me any clue or direction on this?
Thank you in advance

'85 spider wiring diagram

Do you have a wiring diagram for an '85 spider? If not, is the '84 diagram the same? I have 2 '85's and they ahve some wiring differences. One (veloce) was built 10/84 and the other a graduate (I think) 2/85. They are 1699 cars apart in sequence. I will be happy to make a site donation if you have a diagram that will work for me. By the way the grad. has a switch push type (inoperative) oprated by the hood located on the passenger side (looks factory but it's. hard to tell since the wire is cut off) and another of the same type on the driver side operated by the trunk lid. I havent traced those wires yet. Neither of these switches occure on the veloce which seems to be unmolested in any way.

'85 wiring diagram

I have 2 '85's and no good wiring diagram. They are slightly different with some extra switches on one which I think may have been installed by PO. If tou have diagrams available for the '85 please reply and I will be happy to make a site donation
Thanks - Conrad

The 10103 Giulietta Spider diagram I have shows eight wires connected as follows to five terminals on the regulator;

Terminal A1 - three wires; black to horn relay, 16ga red to headlight flashing relay and a 10ga red to the hot side of fuse #3.
Terminal A - one 10ga red wire from the battery cable post on the starter.
Terminal F - one 16ga black wire to the F (I think) terminal on the generator.
Terminal D - two blue wires, one 10ga to the generator and the other to the dynamo light on the dash.
Terminal E - ground

I suspect though that you may have a 750 Series car and I don't know if the wiring is the same. I'll try to find out....

Sorry, but I don't have an 85 diagram; only 84 and 86-88.

If either of you would like these diagrams, please send me your email address in a private message and I'll get them to you.
