944 Turbo Electrical Nightmare? | Removing the 38-Year-Old DME Engine Wiring Harness

In this video, I tackle two major reliability issues on my 1987 Porsche 944 Turbo (951) — starting with the removal of the original, 38-year-old DME wiring harness.

Aging wiring harnesses are a huge and often overlooked problem on classic Porsches. Heat, vibration, and time can cause brittle insulation, internal breaks, and intermittent electrical issues that are nearly impossible to diagnose. Rather than chasing ghosts, I remove the factory DME harness and ship it off to Kroon Wire Harnesses in the Netherlands, one of the most trusted names in classic Porsche wiring restoration.

If you’re dealing with:

Random electrical issues

Drivability problems

Sensor faults that don’t make sense

Aging insulation or cracked wiring

…this is a repair worth understanding.

While the car is down, I also work on replacing a leaking power steering reservoir and hoses, another extremely common failure point on the 944 Turbo. Old hoses, hardened o-rings, and contaminated reservoirs can lead to leaks, noise, and premature pump failure if ignored.

This video shows:
-How much work is actually involved in removing a 944 Turbo DME harness
-Why wiring age matters on classic turbo cars
-What to expect when sending a harness out for professional restoration
-Power steering reservoir and hose replacement basics
-Real-world ownership of a nearly 40-year-old Porsche — no shortcuts

This is part of an ongoing Porsche 944 Turbo restoration and maintenance series, focused on reliability, proper repairs, and what it really takes to keep these cars on the road as a 100% certified amateur.

If you’re restoring, maintaining, or troubleshooting a Porsche 944 Turbo, this is one you won’t want to skip.
