get yourself a plug from a porsche breakers yard or from a porsche specalist.
i have sorted out which wires go to which pin on the plug they are as follows:-
1. temperature sender input
2. minus
3. internal lighting
4. hi-beam for head lights
5. turn signal tell-tale
6.oil warning light
7. plus
8. fuel sender
9.fuel reserve light
10.handbrake light
11.battery/ alternater charge light
12. plus
numbers 2,7 and 12 just seamed to be as what they are listed as and these were taken from a main porsche dealer electrical manual.
hope this lot helps you on your way.
