Both, but this ONLY applies to EC2s whe= n used on 20B engines.   EC3s do not require the diodes even on 20Bs.

Sounds good Mark,  that's the way it's supposed to work.

Hi Tracy, =20

Well, it looks like your hunch about the diode being bad wasn't very fa= r from the truth.  Actually, when I started looking,  R2 & R3 b= oth had diodes, but not R1, the diode was actually missing from R1.&nbs= p; If that wasn't bad enough, I also discovered that some time in the p= ast, while changing intake designs, swapping injectors, etc., I ended up wit= h the diodes on the secondaries instead of the primaries.  So, I just w= anted to check to be sure as to how they are intended to be wired.  Can= you please explain so that I can maybe get it right this time?
