Zenith Blue Hardtop
 

Looking for a Zenith Blue Hard top to fit 1999 Boxster.
Is there wiring for rear defog?
Thanks.

I can't help with the top, but the wiring for the defroster is already in the car. Look behind the driver's seat (between the seat and the outside of the car). You will see a small rectangular piece of plastic connected to wires. The top flips up exposing the connector for a plug that is fitted to the hardtop.

The defrost switch that turns on the heated mirror turns on the rear window defroster.

Good luck with your search. It took me about 3 months to find mine, and arctic silver is much more common than zenith blue. You may need to consider painting another color top to match.
