NEW ENGINE WIRING HARNESSES FOR THE PORSCHE 964 — IN STOCK!

For the Porsche 964, we supply brand-new engine wiring harnesses, available directly from stock.
Depending on model and production year, there are three different versions:
964.607.016.01
964.607.016.02
964.607.016.03

But these are not just wiring harnesses.
Every single 964 engine harness is carefully handcrafted by our specialists, with exceptional attention to detail. From the correct connectors and terminals to the routing, protection and finishing — we consider every harness a true piece of craftsmanship.
A masterpiece for the masterpiece that is your 964.

There is also a very important reason to take the condition of your original engine harness seriously.
Many original 964 engine harnesses suffer from a notorious ageing problem. Due to the biodegradable insulation materials used at the time, the insulation can deteriorate, become brittle and eventually disappear completely.
What remains can be exposed wiring inside the engine compartment.
In other words: a ticking time bomb that becomes increasingly dangerous as the harness continues to age.
A serious short circuit in this part of the electrical system can have devastating consequences. Certain circuits are connected directly to the battery supply, meaning you simply do not want to take that risk in a valuable Porsche 964.

Have your original engine wiring harness inspected — and replace it before deterioration turns into a serious electrical failure.
Through our worldwide network of certified installation partners, inspection and professional replacement can be arranged quickly and correctly.

Protect your 964.
Preserve its reliability.
And give it the wiring harness it deserves.

Not just another distributor cable.

The early 1975–1976 Porsche 930 Turbo uses a different distributor arrangement than the later models.
On these very early Turbo engines, the distributor rotates clockwise, which is why this specific blue distributor cable is different and essential for the correct application.

Our reproduction is made specifically for these early 930 Turbo models, with the correct connectors, dimensions and distinctive blue cable, closely following the original specification.

Article number: 930.602.911.00

It is one of those small but important details that distinguishes the very first 930 Turbos from the cars that followed.

Preserving the details that make the early Turbo truly special.

Another Porsche classic is getting the wiring it deserves.

Today this brand-new engine wiring harness for a 1990 Porsche 944 S2 left our workshop, heading all the way to Upton, Massachusetts, USA. 🇺🇸
Article number: 944.607.040.08

After more than 35 years, the original engine wiring in a 944 S2 has endured countless heat cycles, vibration, oil, moisture and general ageing. Connectors become brittle, insulation hardens and electrical resistance can increase — all of which can eventually affect reliability.
That’s exactly why we reproduce these harnesses.

Built from scratch using high-quality automotive-grade wiring, correct connectors, terminals, protective sleeves and carefully reproduced routing and dimensions. Designed as a direct replacement for the original harness, while bringing the electrical system back to the standard these cars deserve.
No repairs. No patched-up old wiring. A completely new engine harness, ready for the next decades.

From our workshop in the Netherlands to a Porsche 944 S2 in Massachusetts — another piece of Porsche history kept on the road.

Engineered. Reproduced. Built to last.
