Thank you for your welcome and responses; as I get more permissions I shall browse more threads and contribute where I can.
The 968 loom is an interesting one .... looking through Katalog the wiring looms and variants are shown, and there is no specific wiring loom variant shown for CC even though all the CC hardware is shown and itemised.
This would suggest there is no variant for CC and hence it is incorporated for all.
Under the dash behind the clutch on my 968 is the wiring and plug for the clutch release switch, why would that be there if it doesn't feed into a CC loom?
I have searched various fora and can find no definitive answer to this situation, and as mentioned, most diverge fairly rapidly to the 944 models.
I think I shall attempt to contact Porsche Stuttgart direct to see if they can shed any light. I'll get back to you if I find any useful answers.
