Default 993 coils connection scheme

Received the 993 coils for my 964. Not clear what is the power (12v) and what is the ground connector on the coils.
Anyone has info on the connector connection scheme?

Thanks in advance!

The studs are two different sizes as well as the wire terminals. They will only go on one way unless you modify something.

Studs are exactly the same on the 993 coils.

The ones I put in my car last month were different sizes. I even reused the brass nuts/washers from the 964 coils on the 993 coils too.

Have you actually measured them or tried to put the same nut on both posts? Or are you just looking at them by eye?

Strange thing is on pictures on the web the poles are indeed different. Mine are the same, it's an original new Bosch coil pack.
