I hope to have pricing very soon, and pictures of the wiring harness to go with it.

Quick Carl:
I am interested in where you are sourcing the Bosch/Porsche plugs and the 14 pin connector for the engine harness. I just made harness and was looking into sources for these parts. If possible, could you let me know who the vendors are and ballpark pricing. Also if I could source them from 928 Motor Sports.

Thanks in advance

If you send me your email address, I'll send you an attachment (msword) of a Fuse Panel / Wiring assignment list I made. I find it very helpful finding electrical problems. It is for a '79 but is real close for all ob's.

I don't care about the harness color.

The remaining parts of my harness are rigid with age.

Count me in.

Alex - I'd appreciate that wiring assignment sheet as well.

I'd prefer black, if I had a choice. The factory original color (L-Jet) is not all that exciting, it's downright ugly.

Default Engine Wiring Harness

Here is what my research shows me:

78 thru 82 uses one wiring harness - 928-612-002-00
although there is a - 01 option in there possibly.
This is the engine wiring harness we are working at replicating now.

I do not have a L-Jet car here to look at right now - somebody tell me if the injectors have there own wiring harness separate from the engine harness?
The "engine harness" that I speak of starts at the 14-pin connectpor on the right front fender near the auxillary positive post, and goes to alternator, warm up regulator, oil pressure sender, etc.

It looks like 1983 is a red-headed step child - all by itself with part number 928-612-002-05

84 thru 86 uses the same harness, 928-612-001-07

87 thru 91 uses 928-607-002-14

92 thru 95 uses 928-607-002-17

The quote is now in and it looks like we will be able to offer the full replacement engine wiring harness for $419.00 ea.

It will have a new 14-pin connector on the end where it plugs into your right front fender, and all new Bosch bail-type connectors too. The wire loom will be black in color. All new copper wires of slightly larger US AWG wire gauge than stock, and of course all new wire ends.

We are having these professionaly made by a automotive harness maker - this is not a homemade/handmade deal. Compared to what the 356 owners and the early 911/912 owners are paying for replacement wiring harnesses, this is right on the money. Remember that this part is no longer available from Porsche and the used ones are just as old and corroded as the one you have.

I will have a sample in 1 week or so to take pictures of and post.

I have to order 10 engine wiring harnesses at a time. I will take orders now, and when I get to 5 pre-paid orders, I'll pony up for the other 5 so we can place the order right away.
(Sorry I will not pay for 10 of them "on faith" like I did the 200 A-pillar gauge pods - out of 86 people on my list that said "I'f you make gauge pods I'll buy one" we have sold 5....)

This first production run of 10 replacement harnesses is for part number
928-612-002-00 for 1978-82 Porsche 928.

I understand your frustration on the Gauge pod thing. Those pods are GREAT, and we all wish for you to continue to offer these imaginative things for the 928 people. Maybe just limit it like you are with the looms.

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.

Carl I had another customer call me today when he turned Off the key the car continued to run which can happen when power cross feeds in that harness. All kinds of weird and nasty things can happen when the main power feed from the alternator finds its own path !! Order me one of those harnesses the very brown 1980 is in need , no point in putting it off any longer waiting for something to FRY . What is the ETA after you have enough orders ??

Carl, sounds like you are talking about the wiring that runs across the top/front of the motor, down to alternator, oil sender, oil level sensor, etc. I had to fabricate a new one. I elected to run mine across in front of the radiator, then down behind the ps pump, then across to their termination points. It would be more advantages to re-route this part of the harness to get it off the motor and away from exhaust/engine heat, and possible oil leaks. Any thoughts? This would mean splitting the cold start system wiring from that harness, and basically ending up with two seperate units. Will be more more work to fabricate, but will be a superior unit.

Hi Carl:

I don't have a need for a wiring harness (yet), but wanted to thank you for developing products that help keeping the sharks on the road.

Keep up the great work!

Sparks is right -- in my engine removal I've thought a lot about rerouting it away from harm's way and also out of my freaking work area

Jim - I am told to expect 3 weeks from the date I put in the actual order.

I am told that they have the production sample almost done, and I am insisting they send it here to me for my inspection. Then I will also take pictures of it and post them for all you guys.

Only then will I take orders for it - although anybody who is interested should put their name on this thread.

Jim Bailey (again) would you check my post further up in this thread and see if you agree as to the number of different versions of the engine wiring harness used? I plan on making them in reverse chronological order - oldest first - but hop not to have to inventory 16 versions for Chrissake - help me determine what the minimum number of variants is.

Thanks to all you others for your kind words - we are ALL trying to keep these fine automobiles on the road.
