Installing a New Kroon DME Wiring Harness | 1987 Porsche 944 Turbo Restoration (Part 4)

In Part 4 of my Porsche 944 Turbo restoration mini-series, I install a brand new DME wiring harness from Kroon Wire Harnesses on my 1987 Porsche 944 Turbo (951) — one of the most important electrical upgrades you can make on these 40-year-old cars.

The original wiring harnesses on 944 Turbos are now decades old and commonly suffer from:

Brittle insulation
Internal wire breaks
Heat damage
Intermittent sensor faults
Charging and drivability issues that are extremely hard to diagnose

That’s where a professionally rebuilt Kroon DME harness comes in. These harnesses are expensive, but they are built to modern standards, using new materials, correct wire colors, proper shielding, and factory-correct routing — eliminating countless electrical gremlins in one shot.

Advantages of a new DME wiring harness:
Restores reliable sensor signals
Improves starting and drivability
Eliminates intermittent electrical issues
Reduces false fault chasing
Increases long-term reliability
Protects your DME and engine

In this video, I show:
My experience installing the new harness
The challenges I faced during routing and connection
Why this upgrade is worth considering on any 944 Turbo
That this job can absolutely be done by a 100% certified amateur with patience and care

This is doable if you take your time, label connections, and follow a methodical process — and the payoff is huge for reliability.

If you’re restoring, maintaining, or troubleshooting a Porsche 944 Turbo, this upgrade can be a turning point in making the car run like it should again.

👉 This is Part 4 of the restoration series — more testing, driving, and results are coming soon.
