348 door wiring loom - cable colours?

Do you have the wiring diagram?? I just took my 348 back to my shop because they had wired up both sides of the passenger door multipin connector using the colors of the wires on either side as a guide. I ended up with the door ajar lights, dome light and key buzzer turning ON when the door is closed and OFF when it is open.

Do you have any idea how hard it is to steer, shift, and hold the passenger door open to keep the buzzer off at 90MPH on the freeway?

So I guess I'm suggesting use the colors as a 35,000 foot guide but check with your multimeter to make sure you're lining up the right circuits.

Cheers
Kevin

 

There should be 18 active pins in the driver's door jamb connector. I have a list of the color codes taken from the Workshop Manual, cross referenced to the pin number imprinted on the connector, and where these wires go inside the door. Will type out the list later this evening and post, unless someone else does it first. OK?

 

Yes I do - will bring it to the office tomorrow and scan it for you. However, Miltonian, I don't have the information that you have so I'd be interested in your write up as well for future reference.

And yes, damn these bloody Ferrari electrics. I drove 50 miles today with the effing key buzzer going in the car - kept having to goose the throttle to try and drown it out with the Tubi...!!

Cheers
Kevin

Edit - Miltonian, I DO have the repair manual or at least a bunch of it. What page is the color-coding list??? Maybe I can save you typing if I scan that page as well.

 

Kevin: I don't think scanning the wiring diagrams will work very well, and would require several pages. The print is too fine. Here is what my notes show from careful reading of the Workshop Manual, based on the pin numbers found on the connector:

1) White - to RH door power window control switch on LH door
2) Blue - to LH door locking actuator
4) Black - (splits into three) - to RH power window control switch on LH door, to LH door locking actuator, and LH power mirror
5) Brown/red - to LH door locking actuator
6) Violet/white - to LH door locking actuator
9) White/red - to LH power window control switch
10) Brown/white - to LH open door indicator light
11) Blue/black - to power mirrors control switch
12) White - to power mirrors control switch
14) Violet/black - to LH door speaker
16) Red - to LH power mirror
17) Yellow - to power mirrors control switch
18) Red/black - to LH door locking actuator
19) Orange - to LH open door indicator light
20) Blue/red - to LH power mirror
21) Yellow/red - to RH power window control switch on LH door
22) Yellow/black - to LH door locking actuator
23) Green - to LH door speaker

There should be 18 active pins in the connector. I took only a quick look at the bundle in the car itself, this is based on the wiring diagrams in the factory Workshop Manual. For fine detail on the exact function of each wire, you would need to do a careful study of the diagrams. This should get you started at least.

 

Yeah - was gonna let Adobe .pdf do its thing and see how it comes out. Can't be any worse than what he is using now!!!

Geoff,

Had the same problem. Just kept replacing the wiring pins. I pain in the ass.

 

Geoff,

Had the same problem. Just kept replacing the wiring pins. A pain in the ass.Looking at the coloured wiring desciptions on this thread. Mine seem to be different for some of them. Might be due to being a later 348 model 1994 spider.

Cannot really remember the wiring colours. Just played around with them.

 

Here's the wiring diagram for you - just realized as I am checking the .pdf that I did not bring the sheet that decodes the numbers for you - I have that in the book but only brought the one page. Can do the other on Monday if you need it.

HTH.

Good Morning All

My name s Mohammed and i have just signed up to Ferrari chat, i am having issues with my driverside door loom, could anyone be kind enough to share an image of the window switch plug please, my wires have snapped off and i am unsure which go to which pin as its been repaired in the past with random coloured wires.
Thank you

 

If you go the 348/355 forum and search for door connector, you may get a few thousand hits... and images like this:

Which plug wiring is damaged? Car side or door side? Passenger or driver? LHD or RHD?

Anyway, here is a wiring diagram for the Windows/Doors

Link expires in 6 days.

The wiring diagram does have a graphic of one side of the door plug, but you may have to flip it and/or spin it to get the correct orientation.

e.g. driver's door:

The second image is a rough equivalent of the photo.

There are extra wires on the Spider. The pin numbering is in horizontal rows approximately aligned with the keyway.

Please let us know how you go.

 

Good Morning All

Thank you Qavion for the photo, my Ferrari 348 is a RHD, it has the 355 body kit fitted with the 355 door cards and window switches, when the conversion took place, the previous owner replaced the plug sockets to accommodate the 355 window switches, these wires have now snapped off and i am unsure which go where.

Thank you
Mohammed

 

There was a conversation on the 348/355 forum about RHD cars, but I can't remember the details. I can't remember if the harnesses are mirrored.

Looking at the F355 diagrams, the window switch internals seem to be completely different from the 348's. It's anyone's guess how your switches are wired in. When you say the plug sockets were changed, do you mean the 348 circular connector on the door hinge was changed to an F355 rectangular connector? Or do you just mean the window switch connectors? Do the 348 window switches have backlighting? It's not shown in the wiring diagrams.

Here is the F355 diagram:

Hi

The main loom is as original with the round connector, i have the 355 window switches (not sure of the backlight on them), the wiring has been modified at the point of the connectors accommodating the 355 switches , i hope i am making sense lol

 

Sorry, I misread your original message (I have a habit of doing that). You did actually specify switch pinout, not circular plug pinout.

With the two diagrams I supplied, are you able to determine the pinout?

Anyway, with the search words "window switch wiring" specifically on the 348/355 forum, I got some interesting hits. e.g:

How the original wiring diagrams for the 348 were in error (My first wiring diagram has the applicable corrections.):

How to diagnose 348 switches:

But are you still trying to use the F355 switches? Do you want us to come up with possible ways of using 355 switches on a 348 or can you figure it out yourself using the two wiring schematics?
