Does your existing wiring harness look like this rats nest?

 

 

 

 

Broken casing, deteriorated or missing boots, spliced or cut off branches, melted, brittle or broken wires causing internal shorts?

You can be certain that the original wire terminals are definitely dirty, corroded and worn out.

All of these conditions adversely affect the electrical connectivity of a wiring harness.

 

 

No Connectivity, No Joy

 

 

 

Replacement Porsche 914 Wiring Harnesses

 

The engine bay wiring harnesses in our Porsche 914 cars are vitally important components and are exposed to severe degradation and contamination from heat, vibration, rain, oil and just ordinary handling. The original wiring in our 914s is four decades old and new OEM wiring harnesses are not available anymore. The unique original parts for harness repairs are nearly impossible to find…you will not find them at your neighborhood hardware store or even at the best German car parts stores. Used original wiring harnesses can be found, but these original wiring harnesses, are also likely to be at the end of their service life. Heat degradation and fluid contamination cause the harness casing, protective rubber boots and wire insulation to harden, crack and break off, eventually causing internal wiring harness shorts. Vibration contributes to wire breakage at wire terminals and intermittent contact. Dirt and corrosion at the wire terminal connections inhibit electrical conductivity. ~40 years of disconnecting and reconnecting the connectors from the engine simply wears the wiring harnesses and their connections out and causes them to fail. With any of these conditions you could be sitting by the side of the road instead of canyon carving. Installing carbs is not your only option, and may not be the best solution either.

 

We rebuild repair and restore the critical engine bay wiring harnesses for the Porsche 914. We make replacement wiring harnesses for the harnesses that see the most abuse and deterioration because we want to do our part to keep these great cars on the road for many years to come. Not surprisingly, many customers have conveyed to us how these replacement harnesses have cured long term, previously undiagnosed problems such as intermittent stumbling, a bouncy tach, a faulty idle, lean/rich conditions, or that replacing or repairing a harness was the actual solution to what was thought to be a faulty fuel injector, bad pressure sensor, defective coil or an electrical system charging problem.

 

Let us explain what we mean by ‘rebuilt’. We could easily call these harnesses ‘new’ and mostly they are, except that certain original hard plastic housings and other miscellaneous parts which are no longer available new, and only where those items are perfectly serviceable, are reused. Everything that can be replaced is new. New correctly color-coded wire, new wire harness casing, new wire terminals, new rubber boots…you get the idea. Our list of satisfied 914-owner customers is extensive, and these harnesses have helped keep the factory fuel injection on many 914 cars.

 

The research and development required to make these harnesses to the high quality that they are is extensive, including rigorous in-service testing. They may appear easy to make but do not be fooled into thinking you could do your own in a few hours, they are much more difficult than they appear. Over four years in development and testing, each FI harness takes most of a day to fabricate, even with all the correct parts, special tooling and experience on hand. You receive the benefit of all of these things at the lowest price possible and with quick delivery. Our replacement harnesses are configured identically to the original OEM factory wiring harnesses and are handcrafted to exacting standards using new, OEM or better quality components, without being overbuilt. New high-count multi-strand copper wiring with correct color coding and upsized wire gages is used with new OEM wire terminals and durable new harness casing. Original, serviceable, hard plastic parts are cleaned and reused because they are not generally available new. Our wiring harnesses feature extra-durable, new rubber boots (the finest-quality available), and casing reinforcements at critical wire terminals and internally to the harness, for long-lasting durability. Great care is taken in the workmanship of every harness, and each harness is comprehensively bench-tested during fabrication and again at completion. Each harness includes an electrical circuit diagnosis and installation diagram to make the installation of each harness a simple task.

 

Unsolicited responses from customers we have received since 2001:

 

“Have to say the harnesses look mighty fine…great job and thanks for keeping the 914 alive!!” – Greg G, Massachusetts

 

“OMG!! We received the harnesses and are extremely pleased with the engineering quality and diligence!!”

 

“Jeff, you are an artist and skilled practitioner!  Thank you for the time and effort!” – Darren C, Washington

 

“Jeff, I had to send you an email. The harness that you built is of the finest quality and craftsmanship. I took it

out of the package and I could not stop staring at it. Excellent in all aspects. Installing tonight!” – Steve T, Ohio

 

“Just installed the MPS. YOU DID IT! It's FIXED!. Fired right up. idles great. revs quick. No flat spot

and no bucking…it is definitely a 100% improvement.  Thanks again for your great service.”  – Gary C, California

 

“Top Shelf work and well worth the money” – Steve C, Missouri

 

“Beautiful work. The included literature is both clear and useful” – Jim Thorusen, California

 

“Jeff, I just wanted to drop you a note to say the harness you build for the 1973 1.7 that I am restoring is by far the best piece of

craftsmanship that I have seen in some time.  Although I think your harness far exceeds the factories version, what I especially liked

are the dust boots.  The fit is tight, snug and creates a very good seal.  Thanks again” - Hayward S, Washington

 

“It looks like it should be on the Space Shuttle” – Steve S, California

 

“Jeff, You are a lifesaver!  I had struggled with fuel injection issues for a year and I was at my wits end about what I could do to rectify those issues.

Once I installed the new FI harness all those problems went away and my 1.7L is back to being a car I love!

You provide a hugely valuable service for us that no one else I know of does.  Thank you for that!”   - Greg R, Colorado

 

“The build quality is excellent, the components are superior, the appearance is great” – Brad Anders, Arizona

 

“Better than OEM Factory…solved all of my problems” – Bob H, California

 

“You Rock..You Rock..You Rock..!!!” – Rex L, Colorado

 

“I have received the harnesses, thank you so very much for building it and assisting with the shipping. The quality

and the workmanship of the harnesses are flawless!  I feel like wrapping it in clear plastic

 just to keep it looking that good!” – Christopher G, South Africa

 

“Aloha Jeff, I've gotta tell you, those aren't harnesses you sent, they're works of art. By far, these are

the most beautifully-prepared and restored harnesses I've ever seen. I wish I could have received the

same quality of workmanship for the harnesses I've installed in other vehicle restorations. I can't wait to get these

installed, and have the car back on the road.  Many mahalos” - Scott M, Hawaii

 

“I received the MPS yesterday and have to tell you:   My car has never ran nicer!

It started right up, no stalling, and went on a small Christmas Eve road trip.  I'm really psyched.

Great job and thanks again!”  - Ron W, New Jersey

Rebuilt MPS–Manifold Pressure Sensor for stock 1.7L and 2.0L D-Jet 914 engines. 

 

Sorry, I do not offer MPS calibrations for custom engine configurations including the 2056 engines.  A custom calibrated MPS requires custom tuning on a dyno or exhaust gas analyzer by a qualified technician, to meet the requirements of a custom engine.

 

Cleaned, rebuilt with a new diaphragm and gaskets, calibrated and bench tested.

0.280.100.037

1973 2.0L

MPS calibration notes:  Rebuilt MPS are calibrated to the known values of NOS MPS’s.  These values are verified to be generally accurate for the specified engines, but may not be precisely correct for your engine, because your engine may not be in the same state of tune, wear or condition as a factory new reference engine used to determine the NOS MPS calibration values.  Consider that the MPS calibration provided is as close as possible, but for optimum performance your engine/fuel injection system should be evaluated on a dyno or exhaust gas analyzer and adjusted accordingly by a qualified technician.  So that the MPS can be accessed easily for adjustment, the outer MPS stop receives only a drop of clear nail polish to hold it in place and not a full epoxy seal.

 

I do not offer MPS calibration-only services for MPS’s that I have not also rebuilt.

Cleaned and rebuilt:  $312.
