Even where wires seem to have been reasonably well protected by the PVC (?, whatever the now-inflexible black tubing is) you can feel that the wires themselves have become significantly less flexible as compared to what you can feel in the parts that go into the passenger area. I know that people on here that really prefer to keep things original looking will disagree with the choice, but I went with putting everything in InsulTherm to try and protect things as well as possible. Granted, the materials that Porsche chose have held up very well for decades (!), so I can't fault the original choices, but I also think that material science and the fruits of its development are much more readily available now to Joe Consumer and should be taken advantage of. At the very least, this is what I plan to do with my own 928 once I get that far; I have all the tools and wiring I need now from my current project.

Good luck
