tail light connector info needed

Post by rridge » Sat Jun 15, 2013 4:01 pm

On my '81 Spider I need to repair several of the tail light wires where they
enter the large white nylon connectors that fasten 6-7 wires to the the top of
the right and left corner circuit board cards that hold the taillights. They
were apparently damaged many years ago by temporary trailer light
connections.

The cleanest way to repair it would be to release the individual wire
connectors from the nylon block, cut back the damaged section and install a
new crimp connector. However, the connector block is a style I've not seen
before and my usual techniques to release the individual wires from it have
failed.

Also, the individual female wire terminals inside the block have an
unfamiliar shape, perhaps because they are intended to latch onto the edge of a
circuit board. I need a source of new matching crimp on connectors to attach
to the cut back wire ends. Any suggestions on how to disassemble the
connector blocks and individual connector sources would be welcome.

If you look at the end with the connector and have the locating notches up,
you will see to the left of each connector is a small square notch. the
connectors have a tong on them that keeps them in place just like the normal
Fiat connector. If you slide a small screwdriver down that notch, you can,
with some effort depress the tong and remove the connector from the wire side.
Major word of caution. this old plastic is quite brittle and the chance of
trashing your clip before you get the tongs to release is quite high. The
secret is to grind your screwdriver to look like a chisel. (doesnt have to be
sharp). the flat side orientation is toward the connector. I have no idea
where to find the connectors. Might be able to refurb the ones you have. PM me
if you want pix. Your current harness should have a color code tape on each
end. note that so you can put it back in the same way. Also send me the info
since i didnt pay attention to mine.

Re: tail light connector - solved

With a little snooping around the Ferrari Chat website, the problem was solved.
The large white nylon connector blocks used on the tail light circuit boards of
late Spiders are similar to the connectors used on the printed circuit boards in
similar vintage Ferrarii.

There is a nylon cap that at first glance looks to be part of the connector
block but simply pries off with care and the right tool. Once off it reveals
individual wire holders that can be removed by pulling with needle nose
plyers. The wires can be lifted out at that point, repaired and replaced.

Russ,

I'm thinking that there must be differences in the tail light connectors between
your '80 and my '81. I had none of the usual tangs you describe to release the
wires in my connector blocks. In fact there were no crimp-on connectors on
the wire ends, much to my surprise. Each wire was simply pushed onto a barb
which stripped away the insulation and held on it by a removable clip that
looked a lot like a crimp-on female spade connector but was just held in place
by the nylon cap that locked over the top of the connector block with friction.

As far as a right and left side for the small harness that connects the two
cards, I have no colored tape to code them. The connector blocks are
indexed. They only fit the sockets on my card holders when the side of the
connector that has the wires extending out of them are facing the rear of the
car. If you reverse my harness, the connector blocks have the wires
protruding into the trunk and the slots on the tops of the cards will not
accept them.

Take a look at the pictures I've posted above and see if this description makes
sense to you.

I looked at your pictures. it does indeed looked like they improved the
design. Mine are definitely one piece. I fabricated a tool and got all the
wires out. Now my issue is the circuit board. the problem is getting the side
marker to light. the bulb, socket and connector check out, but when plugged
into the board it wont work. when i play with the center connector on the
taillight bulb, i can get it to go on, but it wont stay on. It appears to draw
power from the taillight center connector that is rivited into the circuit
board. The condition of the board is excellent. I just need to figure out a
way to improve that connection. i'm afraid to solder as it could melt stuff i
dont need. If there was some electrically connective paint, it would do the
job. looks like the PO jammed some foil in one of the tab holes on another
light. Any ideas. I havent removed the board from the plastic cover to look at
the other side.

Russ, have you tried using rear window defroster repair kits? I think it was
electrically conductive fluid. I used this stuff to repair Brava instrument
panels.

I have seen rear cards with wires soldered to the connective strips.

I have too, and some of them are scary. Too little heat and you have a cold
joint. Too much and you have a crumbly board. Too much flux and there
are corrosion issues...

These tail light cards are routinely harvested by our favorite Fiat recyclers.
A brief post in the Wanted section will probably get you an offer on a card
in good condition at reasonable price.

Better yet, work on a 78 or earlier spider and work on taillight assemblies
designed in the age of steam locomotives and propelor driven aircraft...no
cicuit boards and plenty of exposed and easy to replace wires.

I found it easier to drill out the pop rivets, remove the crusty old lamp
socket assemblies and replace them with slightly less crusty old lamp socket
assemblies (on the '72) :-) Wires were push on spades IIRC

Does anyone have a picture showing how the connector was disassembled? Or where I can buy new connectors and terminal?
