What prompted you to replace the green wire in the first place? Preventive maintenance? I'm concerned because I have the same MY but I don't have any running problems as of late.
Just wondering.

Orest,
At some point when I replaced my timing belt etc. it got pinched in between some parts which exposed both the inner and outer wires. I spliced it back together as a temporary measure. I have been having some slight missing/hesitation problems during hard acceleration. I decided to replace the green wire in order to eliminate it as a contributor to this.
Max,
There is nothing like a logo, or manufacturer name on either of the connectors. The connectors are molded onto the wire.
Great idea though.

You can add another defective green wire to the list. The old green wire had the one plastic connector completely broken. The terminal positions of the old broken wire were reversed in comparison to the new green wire, and the problem was instantly gone. The new wire has the terminals molded into the plastic connectors, so they can't be taken out and positioned correctly. This particular bad green wire came from 928 Specialists a few months ago, so the problem appears to be a manufacturing defect that ended up getting shipped to at least several different parts suppliers.

If you cannot switch the terminals at the distributor end, then the wire is junk.
The green wire has an internal signal wire shielded by a braided ground wire (just like cable tv wire). Running the distributor pulses in the braided wire is bad.
Distributor to harness connector:
(Signal wire is white, braided wire is covered by black shrink tube)
Harness connector to spark box:
I took the pics in order to show how to switch the wires at the harness end, but then realized how silly this would be!
I need to replace my green wire because the connector disintegrated, note the "racers' tape" holding the wire into the harness connector! Plus the wire has some 90deg kinks in it, which is bad for this type of wire. Avoid sharp bends with shielded cable!
FYI: Pelican sells a distributor wire for $35. I don't know if it's OEM (or green).

I am reluctant to purchase another one unless I KNOW it's good. I'll drive around with my patched one until I can work out something better.
The green wire I bought is useless. There is no way to repair the problem, exchange is the only solution I can see.
PorKen,
Yeah the thought of messing with the ECU connection is pretty distasteful isn't it?
Pelican sells them awfully cheap.....I wonder if there is more to it than meets the eye.

the green wire in question is only available from Porsche the batch with problems seems to be the 02 : 10 : 2002 production run . Porsche in the quest for short term profits has had a number of " price adjustments " . It is very easy for a retailer of parts ( who does not inventory parts ) to take an order based up what they last paid for something and when they order it and take delivery pay more for it than they sold it for . A Porsche dealer now must pay about $43 to buy one from Porsche Cars North America . Anyone buying from a dealer must pay them more than that . In my opinion there should not be any " restocking charges" for defective parts . We have ordered several more from Porsche BUT must check them to see if they are correctly manufactured when they arive . Those who got a bad one from us need only ask for a replacement and return the defective part for a no cost replacement . Moral of the story ..."Sometimes new parts do not work" fortunately that does not happen very often .

Well, the original one came from the big three. As you say, it may be that they all source these from the same place. Now that the problem is identified, it should be really easy for a supplier to test them and make sure you didn't send out one with switched leads.
I am surprised we haven't seen any comments from suppliers on this.

I was tempted to tell them where to go when they give me the BS about restocking cost, but 15% of $32 is about 5$, a cheap lesson; needless to say, that's my last order from them.
Oops, do you suppose they visit this site and I just kissed the whole $32 away???

Al D ....I believe they are far too busy taking orders for every model Porsche , V W , BMW , toyota , etc to spend much time reading this list and far too busy to be posting much of a response . Al even though you did not purchase the green wire from 928 International if you send it to me I will send you a new green wire just as soon as I get them in from Porsche and confirm that they are correct . I will be returning several to Porsche what difference does one more make ? The 02:10:02 batch is reversed and causes all kinds of timing issues .

Excellent example of why 928 International and for that matter Devek and 928 Specialists are known as the BIG 3.
Can you imagine getting support and service like that from a discounter?
Kudos Jim

Mitch;
I've had similar problems w/ my 80 Cab. Unfortunately the green wire wasn't my answer, but what I did was to trim the 'nub' on the ECU end of the green wire (both on the inside and outside of the molded white piece). Then just insert it as normal. It will still lock in place due to the catches on either end.
Truely frustrating.
