Former Moderator. RIP Icemark.
One is for referance voltage from the ignition circuit, and the other is to tell systems in the car that the alternator is running.
S5 and FD (FD uses the non-turbo style connectors):

Nope, an alternator and a dynamo are quite different. A dynamo (aka generator) produces DC voltage; an alternator produces AC voltage (hence the name) which is then rectified to produce DC. Alternators are a lot more powerful and efficient, which is why they totally replaced dynamos in cars along time ago.

Cause according to what your saying, our cars using alternators, do not use a 12v dc system?
I never even mentioned voltage. Dynamos (more commonly known as generators) and alternators both have a DC output but they go about producing it in very different ways.

a generator (dynamo) produces dc voltage directly, but not particularly efficiently. it is basically a motor being spun backwards.
an alternator produces ac current fairly efficiently, and then you have a rectifier circuit (usually built into the alternator housing) that converts it to dc.

Well, thanks for the help guys! Got the S6 ALTERNATOR working today 
But the "wheel" on the s6 alternator didnt fit, had to use the old s4 one.. Where can i get a complet kit ? The S4 slips!
