Interest in Replacement Engine Wiring Harness

Thanks, BC, for your post - I hope that everybody will understand what a great deal this is...
I had to get a replacement one for my 83 euro from Europe...
Trust me, it was not cheap (close to $1000), and probably not many more new ones available.
But when my old one came out, I could not believe the state of the wires.
Green, corroded, crumbling apart... It was BAD.
All that engine heat, and corrosion, were not good for those wires...
The new harness cured a lot of my cold-start issues, and strange running problems that I could not track down. I actually think I probably did not need some of the things I did, like the warmup regulator, etc. Because I still had problems, but when I replaced the harness, a lot of problems went away.
If you have a pretty old car, or live in a wet state, I would highly recommend doing this,because it may really help things. Especially people who are rebuilding, etc. Why re-use a crappy old harness, if you can replace it with a new one?
That price is very good.

Wow, this is exactly what my shark needs!
We found out that the Warm Up Regulator wire and the Cold Start wire are open, and we were thinking about fixing it, somehow. I cannot remember off of the top of my head right now, but this looks like it can be a better alternative
Do you guys still have the wire harness in stock? If so, how many do you have left?
Edit: Will this wire harness fit the Euro 928?

I had a prototype with me at Sharktoberfest, but was not satisfied with the crimp-on ends, so we sent it back.
We have 6 on order now, and 3 of them are already sold. They will have copper wiring connectors, and black wire loom. I hop to ship in 2-3 weeks max. If you want to read more about them or get your name on the list, go here:

Injector wiring harness - working on this. We have decided to supply a firewall-forward solution, with a wiring connector that can be spliced in at the firewall. That would eliminate the need to pull the wiring harness thru the dash and all the way to the LH, plus we think the guys that pull their motors every year would like an easy disconnect right there so they can remove the engine with wiring harness attached.
I have all but one of the parts I need for this sourced - shouldn't be long for the rest.

BrianG - I am not certain about that, but I think no. It looks like I will have to have two injector wiring harnesses at the LEAST, one for 16v and one for 32v motors.
According to Mark Anderson, Porsche used a sdifferent injector wiring harness for each of these years:
Unfortunately there are many #s
80-81
82-83
84
85-85
87-88
89
90
91-93
94-95
We will be trying to combine as many as we can so we do not have to inventory that many different SKU's

Still hunting for a few wiring connectors.
From time I locate them all to time I can have a wiring harness is usually about 1 month.
If you are in a hurry, I have the 8 injector clips in new-style Bosch form (no tools required, just squeeze to put on/take off) already in stock for this project.
I could sell you those and you wire them in yourself.

Carl,
For Andy's SC kits, two wires (I think the grounds for the MAF and for the Idle Control Valve) have to be cut and lengthened. Would it be possible to specify which wires we need lengthened by whatever amount, and have those changes incorporated into a "customized" loom that you would build (recognizing that, basically, all your looms are customized...)
Thanks,
Brian

bdonaldson - just saw your message because the engine wiring harness conversation has moved to another thread. I do not think I want to get into a custom one-of harness like that, just lengthen the wires you need and seal with het-shrink tubing and you'll be fine - and save $$ too.

5 years later......I'm finally getting around to putting a new harness on the 79.
Received it from Carl and the fine folks from 928 Motorsports today, and am very pleased with the quality of workmanship and materials. It is correct, and I will install it Saturday.
