2004 996 w/MOST Bypassing Amp need speaker diagrams

[RTSC4S]

Installing Alpine setup and have nifty little bypass Adapter from EuroMotorsport. It gives you multiple connection sites and butt fits right into amp harness once its disconnected. The problem is there are only 5 sets of wires in this cars case. 4 +/- terminal
Pin 1,2,4,5 (correspond to color chart) Pin 3 is Brown - Blue +
This would direct me to 5 speakers but there are 7.Taking sub as one channel

Now either Porsche branches off at some point and that is the info I need to verify so I can either
1. run wires from my aftermarket amp to it
2. find out its impossible and run dedicated wires to each speaker from amp...big time drag but may be the only solution.
Any help appreciated?
