Need help identifying unconnected wire under hood

[peterp]

I found a pair of disconnected wire under the hood and am hoping someone can identify where it should be connected. It is a pair of wires, both are red with black stripes and have female terminals on the end. The wire pair with black rubber surround originates from the right side of the fuse box when standing in front and looking towards the rear of the car. That's not a lot of info to go on, but I'm hoping the red with black stripes is a telltale.

I tried looking in the owners manual, but the electrical diagram is virtually unreadable. I'd also be interested if there is a quality wiring diagram available for the 330 GT S2 -- I've heard that somebody sells these but haven't been able to locate one.

Thanks,
Peter

Smells like gearbox. I think on GTE overdrive switch wires are brown, OD activate wire is red and reverse light wires are red/black.

From the fuse, down to the gearbox switch, then back to circuitboard and into the main harness, then out into the back harness running under the car and into the tail lights...

Peter,

I think Kerry made a large drawing of the Series II 330s. See if he has a better wiring diagram to work with.

I know you have a Series II 330l, but you should put it in your "signature" so we don't have to ask.

Do your back up lights work?

Ding, Ding, Dine -- we have a winner. Thanks Kare and Tom, I haven't been able crawl under to see where it goes yet, but seems like it is the reverse light switch:

Exhibit A: Just checked and the reverse lights don't work
Exhibit B: I originally spotted the wire hanging under the car

Thanks very much for your help.

Tom -- I went to update signature and I see series 2 in it -- maybe you updated it for me?

I am interested in Kerry's drawing if he still has them. I don't have any electrical issues currently, but the OM is useless so would be handy to have.

The problem now is trying to get it plugged back in! You said it has two female plugs, so perhaps the ones going to the transmission are extensions. The switch on the transmission should take males, and is really only accessible by removing the transmission tunnel and the two front seats!

Well, Peter, if you were a registered owner (http://www.330gt.com), you would have just received an annual update with information about the wiring diagrams. Either contact me through the contact page in the registry or PM me here and I'll give you the details on ordering.

And yes, the red/black wires are for the backup light. Originates in the black 4 pole connector in the upper left of the fuse box, then to the reverse switch on the transmission, onto the the backup light in the rear (though a connector in the LH side of the trunk) and to ground through the bulb. It will only work when the L switch (lights) is on and the transmission is in reverse.

Hey Kerry - Do you have to own a 330 to register and get all this cool stuff?

You have to be a registered owner to access the download section that has all of the manuals, etc. on PDF. Registered owners (and past owners) get notified whenever any new information becomes available on their car.

I get a lot of technical, parts availability, etc. questions through the registry. I have a tendency to take longer or do more research for a registered owner than on the random inquiry.

Things like the oil filter wrenches, wiring diagrams, repro warranty books, repro service and assistence books are available for sale to anybody. However, I don't advertise these, so usually it is the registered owners that find out about them. A while ago, I had access to build sheets and I was able to obtain them for quite a few registered owners that were interested. Sadly, that source is gone.

So there are advantages for 330 GT owners to be registered. BTW, PeterP is now a registered owner.

Guilty as charged. You contacted me to register shortly after I bought the car, but I had a lot of work done over an extended period before ever taking delivery, so I didn't have that much info at that time and felt more like an owner in training. By the time I took delivery, of course, I forgot all about registering (though I used the registry quite a bit). I have amended my ways as of last night.

Thanks,
Peter

Kerry - Were the warrantee and maintenance books the same for the GTE? I have the owners manual, but that is all. Do you know if they came in a leather pouch like some other cars did?

Thanks for the info Tom. Sadly, this appears to be the case. I've spent some time under the car and haven't been able to find anywhere where these would plug in.

The S&A booklets changed for each year, as the list of dealers changed. I don't know what they looked like in the early 60s.

The warranty booklet was probably the same, though I don't know for sure. BTW, Parker Hall has some warranty book reprints, but they are for 365 and later cars as the orange background on each page is darker than on the original 330 one I have.

Yes, they would have come in an owner's pouch, see http://www.330gt.com/Literature/OwnersPouch.htm and look at the America and 4HL version. It would have been the same as used for the GTE (and my PF coupe). Scroll down and you can also see pictures of warranty and S&A books.

I did not realize how much stuff there was! I like that the battery owners manual is 34 pages...
