Porsche changed from individual wires to the coil and points with a seperate shield Ground for each to shielded white cables on the '73.5 to '77 models, so ignore my colored wire info for 73 and earlier cars.
One shielded white wire is for the coil, the other is for the points and splits off near the 3 pin to connect to the tach signal with the CDI switched power red wire.
No green wire used at all. That is a PO Hack...
