I understand Mike’s comment. In most cases German cars don’t come pre-wired for options that weren’t ordered from the factory. On the 986 Porsche appeared to make a wiring harness specifically for the options on each car. I retrofitted heated seats in my car and I can attest that there wasn’t any preexisting wiring for that function.

As an exception to the rule the defroster wiring was in my car even though it didn’t come with a hard top from the factory. The harness is behind the driver’s seat if the original poster wants to check. The switch on the dashboard that operates the side mirror defrosters also operates the rear window defroster.

Maybe Porsche thought hard tops would be a common option and decided to add it to every car. I think that all of the early 996 cabriolets came with a hard top unless the buyer chose the hard top delete option when ordering.
