speed control schematic
 

i need a speed control schematic for a 1982 sc. also part locations. (can't find the location of the control unit).
can anyone help?

I have an 87 so it's likely different, but.... Bently manual is wrong for my car. It states the unit is in the trunk around the tach/speedo area. Mine is actually under the dash behind the ashtray. That was apparently a change at some point for the Carrera. It's a bare metal box maybe 6" square and an inch thick...

Yeah .... and in Porsche's infinite wisdom ( like so many other goofy things they do electrically, like not using fuses where they're needed)...the "Tempomat" unit fails "hi" instead of "low"...

Idiots.....

I'm not sure if this is what your looking for, but I spent a little time with that lovely silver box.
