Anyone know The Wiring color codes for a 993 Coil??
 

Anyone happen to know what the + & - sides are on the 993 Bosch coils.


I think I may have a failing coil, and am swapping them out for small MSD coils.

What I'm unsure of is, are the Black wires + or -, or are the Green striped wires + or-.

I'm trying to avoid wiring up the new coils backward..

Thanks,
Ron

The green and black terminals are different diameters,just like the fuel pumps so i would guess the MSD coils would be similar,in other words somewhat fool proof !
