Green ignition wire
Looking for a cheaper alternative to the green wire. Anybody have one or know of a cheaper way of obtaining one? I have seen a $50 wire but it appears to be shorter than the other wires. Would that be a big issue?

Do you know of a magical way to make the ignition signal jump the expanse of atmosphere that will be present since the wire is shorter?
Other than that and having the correct ends to fit the 928, it shouldn't be a big issue.
Just pony up and buy the correct wire from one of the companies that support our love for the 928. It will cause you much less grief in the end.

Not to offend you, but if you can't afford the cost of a proper green wire, I'm thinking a 928 might not be the car for you. They're cheap to acquire these days but were still very expensive luxury cars when new and proper replacement parts for them reflect the original purchase cost not the current market value.

The shorter one is most likely for the 911 which is too short to reach from our distributor to the harness.
While that's a common sentiment around here, for someone 100% new to 928's it does seem a bit absurd a 3 foot piece of two conductor wire is almost $140:

When I looked this up for my response I was in a bit of a sticker shock, it was $70 not all that long ago.
I don't think it hurts to check with the collective. The last thing anyone wants to do is shell out money for something only to find out a week later it could have been purchased for less somewhere else.

I'm fairly sure I could make up a green wire for a lot less than $140. I'm going over to help John today, and he may have a sample of the wire, connectors and plugs I can examine. I've never had a car with a green wire, so starting from scratch here. As I see it, this is a coaxial cable with a weaved shield, and some special ends. Gimme a couple days, maybe I will go into the green wire business. Kinda surprised Sean hasn't already taken up the task.
So far you're doing fine Dylan. Just a bit of patience, and keep asking questions. No harm, no foul, lots of free good brains here to guide us along.

We have tried making the green wire before - the wire is OK and the 2 way male at the 14 pin end is OK. The big deal is the distributor end which is unavailable - I have tried and John Speake has tried.
As a single DIY project where the original distributor end is still intact and usable a remake would be totally possible.

There is some stuff you can 'cheap out' on. There is some stuff you can find a home made alternative for.
But not everything.
There are certain things that you need quality parts to do. Sometimes (not always) the ONLY option is to pay up and get the actual Porsche part. The 'Green Wire' is one of those parts. No real alternative, no way to repair it so it works reliably. Believe me, if there was, it would be on here. (Edit to add: Roger covered what can and cannot be repaired. The distributor connector.)
The crest on the hood comes with a price premium sometimes.
Something to remember (and I've said this more than once), the 928 was the Porsche flagship for quite a while. Most expensive, fastest, most powerful in some (not all) model years.
It cost the equivalent of a mid-sized house when new.
Regardless of how much you can find one for now, parts prices, especially Porsche parts, are going to reflect the 'price when new'.
And if you think this is bad, take a look at what "Porsche Classic" parts are going for. They are in the process of realizing that there are people that like these cars. And bringing back some of the NLA parts. But the are NOT cheap.
If you aren't willing (or able) to pay that premium for some parts (again, not all of them), then maybe a 928 isn't the right car for you.
Not ripping on you, but there's a cost that comes with ownership (at least if you want to drive it).

I'm going to look into 3D printing now. I may need a sample to map. The rubber boot is also going to be a challenge. I'm thinking of 3D printing the whole thing including the boot, and then use a rubber seal bushing around the dist housing.

I fully trust and know your skill set doing things, however, this is one of those areas where as long as a new one is available from Porsche, I'll pay the price. It's not like these are an "every 5 year" kind of a part. I have 3 cars with this green wire and all are close to new. Good chance I'll never have to buy another one in my lifetime (unless I buy another car with one or do something stupid).

Just wanted to be clear my point in saying I'd rather by a factory new one has nothing to do with your ability to make a quality item.

If someone was able to develop a cheaper and effective wire that would be brilliant! Although im looking for maybe a slightly used wire from a parts car or someone just having an extra that they would sell for cheap. Id rather find a wire that is slightly used and cheaper than going to buying brand new expensive right away

Years ago my 79 developed a very, very random misfire that only happened on the race track towards the end of a session on warm / hot days. There is a laundry list of things which could cause such an issue, reality was the green wire. The old one looked fine.
Now could my issue have also been related to a worn / old ignition lead causing the interference? Absolutely, that is why a fully functioning green wire is so important. It's one of those things I'll replace on a CIS / L-Jet car with running issues before anything else. Unless I have documented history showing it's fairly new.
