Why is the "green wire" so special?
 
I was doing some cleanup in my engine compartment and noticed that the end of my green wire is beginning to get brittle and crack. Needless to say I was a bit stunned when I priced this part out. Over $100.00! Tell me what type of magical properties this little piece of wire has that make it so costly. Is there something special about this wire, or is it just a length of wire with factory connectors on each end. :eek:

because its green! DUH

and S4's and later cars dont have them, so they are rare





why is it so special, is the magic green wire as important and the magical blue hose?

It is a shielded cable. Nothing special other than that. If someone locates the connectors it could be fabricated for $5.00.

Shielded- sort of.
The wire has a core that handles one side of the polarity for the signal, and then a braided casing that handles the other. So you have both positive and ground in one casing. I don't get how that doesn't induce a current, or why Porsche elected to do it that way, but I guess it doesn't matter.

The wire is just a shielded coax cable with a Bosch two pin connector on one end. What makes it unique, and pricey, is the pin configuration on the distributor end. Just another case where the Porsche engineers reinvented the wheel. :(

I sell the Green wire for $98.20 and already said the connector at the distributor end is all that makes it special.
John Speake has an alternative for about half the price but we need cores to reuse the connector.
If the connector is toast we are SOL.

I personaly am happy that it is still available new because the cars will not run without it. Which reminds me I should buy one and tuck it away in my personal stash along side the new printed circuit foil that I bought for the very brown 1980....

So Roger, do you require the old wire in order to make the new?

Assume John Speake also requires the old wire?

Just want to clarify if the connector is golden and the ONLY way to create a replacement.

I need to get one for my stash as well, it will go along side my 9 printed circuit boards for my 80.

The distributor pickup is used on the same year 911's. If the 928 version becomes NLA, why not make an extension for the 911 green wire (< price of 928 wire)?

What years is this wire applicable to? Pre-87?

If someone sends me a sample of the magic connector, I may be able to duplicate it..

I don't remember seeing a green a wire on the early 32V engines.

Jim bailey - 928 International 06-11-2008 05:41 PM

Used 78-84 except the LH Euro cars. Not on any 32 valve. Basically all single distributor cars it sends the signal to the spark TSZ unit tach and brain. The crank timing sensor replaced it for L H cars

Porken,

My problems with the wire have always been at the connectors. Would adding an extension double the potential problem areas?

These look like they have a fairly standard 2-pin Bosch connector at the non-distributor end. It's the end at the distributor that seems to be the challenge. I have the modern cable (it isn't green though) for replacement but no good source for the distributor-end connection. Maybe if the 911 cars chew them up too, it would be worth new-sourcing the connectors.

By the time K added her normal mark-up and billing fees, a single replacement would cost as much as a new one from Jim and Mark. Plus the 928 Int'l service and warranty policies are much better. :)
