Wiring Diagram

[ultramens]

Hi, I was wondering if anyone has the wire diagram to a 1999 996 cab. I am trying to install an aftermarket keyless entry system that will also be able to control the convertible top and the windows remotely. Has anyone tried this, does it work? I am not going to disable the factory alarm, but merely bypassing it??? All thoughts are encouraged. Thanks

Is it the device sold by Wilhelmy...Mods4Cars? If so...it works great. You do not need the wiring diagram.

no its not the Mods4Cars version. I was just thinking that it be possible to add keyless entry to our cars, once i have that installed, i would like to add remote window operation and remote convertible operation. I would not be disabling the factory alarm, just bypassing it. If i had the diagram that labels all the wires, then maybe this will work....If anyone has one, please provide, thanks!

Remote windows and top are already a feature of the Porsche system - but they were not offered in the US. As I recall you need a 2 or 3 button key and then reprogram the alarm/central locking controller to a European country. You will need a shop with a PST2 or PIWIS tester to do the reprogramming.

Porsche had sold schematics on their tech website in the past (for $110 each) - but I now see that feature is gone from their site.

These cars already have keyless entry .... at least every 996 I ever saw has it. Have you checked your owners' manual?

The remote window & convertible top operation can be added with a very simple, plug and play device by Wilhelmy. In addition you get the ability to raise / lower top while moving. With the availability of these great products, I can't imagine doing something so drastic as disabling / bypassing the OEM entry / alarm system.

thanks all for the replies. i have the oem keyless entry but the FOB has stopped working. to get a new one, it would cost around the 250-300 dollar range just for a new remote. For that price, i was thinking I could just get a keyless entry system with the ability to operate the windows and maybe add the ability to operate the convertible.

So I guess it all started with the FOB failing and me not wanting to pay 300 dollars for just another remote.....

You need to check Sunset Imports (Porsche Parts at Dealer Cost - link at the top of the page) price on a remote - they are under $100.
