Wiring Harness for a 330 GTC/S

when you have a wiring diagram then make a new harness starting from the fuse board. those cars at that time had not so much wires like today

 

I think you not will get it cheaper than doing by yourself. also you just can put in more wires for may be some more info from the engine, gearbox, differnetial?

 

Romano, making an accurate wiring harness from scratch, especially if trying to replicate correct wire colors and gauges/sizes on this era Ferraris can be difficult and something many will not be able or willing to do and if factory diagrams of 330 GTC/S are as incomplete and incorrect as they are for Daytona*, it can become very difficult.

* I have 4 different, factory drawn wiring diagrams for Daytonas and none are anywhere near complete or correct.
I’ve re-drawn & corrected 2 different (1 Euro, 1 U.S.) diagrams of my own and while they are probably 90-95% more complete/correct than factory ones, I’ve learned that cars themselves can have many discrepancies, including incorrect wire colors, etc on their respective wirings, even if same delivery market and/or close to each other in production timeline.

Ed, while I have a fair amount experience with reproduction harnesses for vintage vehicles (I’ve made several from scratch, including couple for vintage wooden boats), I don’t have any for Ferraris, but will be interested in learning about this also.

 

Although I never bought a Ferrari loom from Autosparks, I can highly recommend based on my experiences with them here in the UK.
I've used looms from them for a wide variety of cars*, they can also customize looms based on drawings and diagrams. (wire colours always as original)

*(Austin Healeys BN1 to BJ8, MGs TC to MGB, Morgans, Mini Coopers, Morris Minor, Land Rover S1, Cortina, Escort, Volvo PV etc. + bespoke looms)

The material they supply have always been to a very good quality and they are always very helpful in finding solutions,

They happen to list the loom for the 330 GTC too, the looms have always been made based on an original loom supplied as reference.

I have no affiliation with the company, I only speak from being a customer over the last 25 years.

Contact them if you wish, to discuss your requirements.

 

timo, I see not big problem to do such wiring when you have the colors all.
start at the fusebox and make them longer than you need
I not would like to pay more than 1.600 GBP, even this is a good price, I expected much more

 

Prices and quality are all over the place. As well as reliability.

I have heard good and TERRIBLE opinions on Autosparks, have tried to order 5 sets for 5 different cars.
Either the gal answering the phone / email, is related to the owner (flagrant, incompetent nepotism)
or she's plainly out of the ball park. Got nowhere. Hope she's cute at least.

What to do? Many have rolled their own in Dinoland, but they are very talented and patient.

Others have gone to other (high and mighty) sources, methinks a direct correlation to the brand, thus upwards of $4K. Crazy.

A FIAT loom is the same as a Ferrari as an Alfa. No science fiction there, all made by the same 2 or 3 companies in Italy at the time.
Just as the ones made in Ukraine last year.

Get ahold of an issue of "Ruoteclassiche" and many advertise there. Who's great? Do not really know.

Go to Italian chats and ask there. Best of luck with the language.

I have original looms all over, so patiently will fasten to a 24' plywood back board and try to retrace the ones missing.

It worked on the "L" Dino, tried continuity on all wires and went through with flying colors. Once all is connected we'll see if she fries or...

Others, we'll see.

that is what I once thought too

 

If this is the case, would Alfa Romeo Forums (alfabb.com) be a place to ask?

 

Road Island Wiring makes a nice harness for a C-type Jag. They do not list a 330 Ferrari but they do list a couple of 250’s. May be worth a call.

Cheers Jim

 

Recently spoke to Rhode Island Wiring on behalf of a friend about making a custom reproduction to match an existing Italian harness, they said no, they don't do that these days.

 

I’ve bought and installed numerous Y’n’Z harnesses in last 35+ years and more than once have helped them to correct some of their patterns, but all have been mainly for vintage American (luxury) cars and designed quite differently than, let’s say, a Daytona harnesses.
If I ever encounter a need for a vintage Ferrari harness, I’ll probably check with them first.

Last time I got a complete harness (including the main and several separate sub-harnesses for tail lights, power antenna, power seat, power windows, A/C, rear seat cigar lighters, etc) from them couple of years ago for a mid-fifties American luxury car (w/perceived value less than $100K), the total cost was closer to $4K than $3K and yet one of their sub-harness patterns needed some corrections, which I helped them with by providing the original one, along with some instructions.
In most case, their harnesses have been dead-on.

 

John Whittington in Virginia specializes in making concours quality harnesses for vintage Ferraris. He is supplier to the Who's Who of Ferrari restorers.

[email protected] 540-335-9443

He also offers rebuilding service of vintage starters, generators, alternators etc.

Good friend, very good guy and really outstanding work.

 

I used YNZ Yesterday's Parts in Redland's CA for my GTE (https://www.ynzyesterdaysparts.com/) and found them to be excellent. They have a large collection of patterns for looms and and I know they have done a number of vintage Ferrari's.

 

If anyone wants a reference for John ask Admiral Phillips. His little blue car was a recipient of Johns attention.

 

We're restoring a GTC now and have the original harness in tact to use as reference. We've replicated the harness in house and it's being installed now.

We could certainly make a second if there's interest.

 

With all due respect Brian, but I imagine 500 Mondial harness is probably 10-20% complexity of 330 GTC/S.

Here's one I restored for a Daytona 10+ years ago.
Like few others I've seen, it had several factory/OEM mistakes (or should I just call discrepancies ?) I was able to correct during the process, but did these "corrections" made it inauthentic ?

So what? Hardly the only one hes done. Just a known, highly respected owner that can vouch for him.

I forgot you are perfect in every way.

The man asked for a source for a very high quality harness and I gave him a known, proven, good, reliable, well respected source.

2 posts before this is also a known, good, proven, well respected source. Dustin works for Motion Products a company that has very real bona fides unlike you.

 

?!?

 

Only God is perfect, and I do not see Him here in either case.
I would kindly request to tone down, as it leads to nowhere and is non constructive.

After all, "cast the 1st stone...etc, etc."

When my GTC was in the rebuilding process my go-to tech said it needed a new harness. I researched a number of sources for a replacement. He said that using the existing harness coupled with the original wiring diagram would be his preferred approach.

Like Timos example it was tired, brittle and hacked. He labeled every wire before pulling the harness out. Then put the old harness on a sheet of plywood with nails to create a pattern that he used to build a new one. Each wire matched the color and size of the original harness.

 

I agree Alberto, except on that "God"(?), but yes, I should've been more attentive and specified my reference comment and photos in post #19 being intended as a reply to your comment on the post #8 about spreading the harness out and retracing it all to find damaged, incorrect and/or missing circuits, etc.

I didn't really expect anyone to get riled about any of it or my (respectfully offered) comparison opinion of harness complexities between 500 Mondial and 330 GTC/S, but hey, live and learn...

 

Dog?
