The Fuel Injection Forum suggested I tell this here as well.
I have a Vehicle Speed Sensor (VSS) for my fuel injection (EFI) and Delphi cruise control. When I installed it I wrapped it with reflective heat tape. After numerous trans/final drive/speedo work the tape was sort of flaking off. It was one of those things "I need to do something about".
I have headers and suddenly had the engine stop while on a freeway. Luckily I was going down hill and there was an off-ramp at the bottom. Looking at fuses I had one burned. Took me a while to find the short. It was part of the VSS/Cruise control but the melting heat did damage to several wires. The VSS had melted and burned wires down into the unit. Clipping the power to the VSS revived the system and allowed me to continue home.
When I called JimK for another VSS he said he had seen this before. So, if you have a VSS for speedometer or EFI or cruise and it is down by the transmission I suggest protecting it. If you have a particularly clever way of protecting things down by the headers, I will be happy to hear about it.
